General

  • https://en.wikipedia.org/wiki/Koomey%27s_law - describes a trend in the history of computing hardware: for about a half-century, the number of computations per joule of energy dissipated doubled about every 1.57 years. Professor Jonathan Koomey described the trend in a 2010 paper in which he wrote that "at a fixed computing load, the amount of battery you need will fall by a factor of two every year and a half." This trend had been remarkably stable since the 1950s (R2 of over 98%). But in 2011, Koomey re-examined this data and found that after 2000, the doubling slowed to about once every 2.6 years. This is related to the slowing of Moore's Law, the ability to build smaller transistors; and the end around 2005 of Dennard scaling, the ability to build smaller transistors with constant power density.

  • Why We Can't Have Nice Software - Andrew Kelley - "Technology, and in particular, software, offers a glimpse of magic; a perpetual motion machine; wealth created from nothing. It offers us a chance to work together on something beautiful; to achieve perfection by ratcheting improvements over time. In the end, this opportunity is squandered in a doomed quest for endless growth." [2]

  • The Garden of Computational Delights - Beneath the utilitarian purpose of computation, computing is also a source of delight and wonder. Software is not just databases and mail merges or SaaS and spreadsheets; it's creative coding and simulated cities, code poetry and bulletin board systems. It's websites that dazzle and iPhone apps that make the heart sing. And it's sometimes even spreadsheets, coerced to dance and do all manner of weirdness. All of these approaches to computing are what am collecting here, and bundling under the term "garden of computational delights." This is a list of places that collect or catalyze sources for being enraptured by the web, programming, and the wider world of computing. Or, as per Tim Hwang and Omar Rizwan, this is a garden of all the different places you might discover where "the computer is a feeling." [3]

  • Portable Hardware Locality (hwloc) - provides a portable abstraction (across OS, versions, architectures, ...) of the hierarchical topology of modern architectures, including NUMA memory nodes, sockets, shared caches, cores and simultaneous multithreading. It also gathers various system attributes such as cache and memory information as well as the locality of I/O devices such as network interfaces, InfiniBand HCAs or GPUs.

Mainframes

  • https://en.wikipedia.org/wiki/Mainframe_computer - or mainframes (colloquially referred to as "big iron") are computers used primarily by large organizations for critical applications; bulk data processing, such as census, industry and consumer statistics, enterprise resource planning; and transaction processing. They are larger and have more processing power than some other classes of computers: minicomputers, servers, workstations, and personal computers.The term originally referred to the large cabinets called "main frames" that housed the central processing unit and main memory of early computers. Later, the term was used to distinguish high-end commercial machines from less powerful units. Most large-scale computer system architectures were established in the 1960s, but continue to evolve. Mainframe computers are often used as servers.


Minicomputer

  • https://en.wikipedia.org/wiki/Minicomputer - or colloquially mini, is a class of smaller computers that was developed in the mid-1960's and sold for much less than mainframe and mid-size computers from IBM and its direct competitors. In a 1970 survey, The New York Times suggested a consensus definition of a minicomputer as a machine costing less than US$25,000 (equivalent to $165,000 in 2019), with an input-output device such as a teleprinter and at least four thousand words of memory, that is capable of running programs in a higher level language, such as Fortran or BASIC. The class formed a distinct group with its own software architectures and operating systems. Minis were designed for control, instrumentation, human interaction, and communication switching as distinct from calculation and record keeping. Many were sold indirectly to original equipment manufacturers (OEMs) for final end use application. During the two decade lifetime of the minicomputer class (1965–1985), almost 100 companies formed and only a half dozen remained. When single-chip CPU microprocessors appeared, beginning with the Intel 4004 in 1971, the term "minicomputer" came to mean a machine that lies in the middle range of the computing spectrum, in between the smallest mainframe computers and the microcomputers. The term "minicomputer" is little used today; the contemporary term for this class of system is "midrange computer", such as the higher-end SPARC, Power ISA and Itanium-based systems from Oracle, IBM and Hewlett-Packard.


  • https://en.wikipedia.org/wiki/Midrange_computer - or midrange systems, are a class of computer systems which fall in between mainframe computers and microcomputers. The class called minicomputers emerged in the 1960s and machines were generally known at the time as minicomputers – especially models from Digital Equipment Corporation (PDP line), Data General, Hewlett-Packard (HP3000 line and successors), and Sun Microsystems (SPARC Enterprise). These were widely used in science and research as well as for business.IBM favored the term "midrange computer" for their comparable, but more business-oriented, systems.




  • https://en.wikipedia.org/wiki/Superminicomputer - colloquially supermini, was a high-end minicomputer. The term was used to distinguish the emerging 32-bit architecture midrange computers introduced in the mid to late 1970s from the classical 16-bit systems that preceded them. The development of these computers was driven by the need of applications to address larger memory. The term midicomputer had been used earlier to refer to these systems. Virtual memory was often an additional criteria that was considered for inclusion in this class of system. The computational speed of these machines was significantly greater than the 16-bit mincomputers and approached the performance of small mainframe computers. The name has at times been described as a "frivolous" term created by "marketeers" that lacks a specific definition. Describing a class of system has historically been seen as problematic: "In the computer kingdom, taxonomic classification of equipment is more of a black art than a science." There is some diagreement about which systems should be included in this class. The origin of the name is uncertain. As technology improved rapidly the distinction between minicomputer and superminicomputer performance blurred. Companies that sold mainframe computers began to offer machines in the same price and performance range as superminicomputers. By the mid-1980s microprocessors with the hardware architecture of superminicomputers were used to produce scientific and engineering workstations. The minicomputer industry then declined through the early 1990s. The term is now considered obsolete] but still remains of interest for students/researchers of computer history.

Microcomputer

  • https://en.wikipedia.org/wiki/Microcomputer - a small, relatively inexpensive computer with a microprocessor as its central processing unit (CPU). It includes a microprocessor, memory and minimal input/output (I/O) circuitry mounted on a single printed circuit board(PCB). Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors. The predecessors to these computers, mainframes and minicomputers, were comparatively much larger and more expensive (though indeed present-day mainframes such as the IBM System z machines use one or more custom microprocessors as their CPUs). Many microcomputers (when equipped with a keyboard and screen for input and output) are also personal computers (in the generic sense). The abbreviation micro was common during the 1970s and 1980s, but has now fallen out of common usage.

IBM PC / AT / ATX

  • https://en.wikipedia.org/wiki/Personal_computer - a multi-purpose computer whose size, capabilities, and price make it feasible for individual use. Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician. Unlike large costly minicomputer and mainframes, time-sharing by many people at the same time is not used with personal computers.


  • https://en.wikipedia.org/wiki/IBM_PC_compatible - commonly known as the IBM PC, is the original version of the IBM PC compatible hardware platform. It is IBM model number 5150 and was introduced on August 12, 1981. It was created by a team of engineers and designers under the direction of Philip Don Estridge of the IBM Entry Systems Division in Boca Raton, Florida.

The generic term "personal computer" ("PC") was in use years before 1981, applied as early as 1972 to the Xerox PARC's Alto, but the term "PC" came to mean more specifically a desktop microcomputer compatible with IBM's Personal Computer branded products. The machine was based on open architecture, and third-party suppliers sprang up to provide peripheral devices, expansion cards, and software. IBM had a substantial influence on the personal computer market in standardizing a platform for personal computers, and "IBM compatible" became an important criterion for sales growth. Only the Apple Macintosh family kept a significant share of the microcomputer market after the 1980s without compatibility to the IBM personal computer.


  • https://en.wikipedia.org/wiki/IBM_Personal_Computer/AT - more commonly known as the IBM AT and also sometimes called the PC AT or PC/AT, was IBM's second-generation PC, designed around the 6 MHz Intel 80286 microprocessor and released in 1984 as System Unit 5170. The name AT stood for "Advanced Technology," and was chosen because the AT offered various technologies that were then new in personal computers; one such advancement was that the 80286 processor supported protected mode. IBM later released an 8 MHz version of the AT.


  • https://en.wikipedia.org/wiki/PC_System_Design_Guide - also known as the PC 97, PC 98, PC 99, or PC 2001 specification, is a series of hardware design requirements and recommendations for IBM PC compatible personal computers, compiled by Microsoft and Intel Corporation during 1997–2001. They were aimed at helping manufacturers provide hardware that made the best use of the capabilities of the Microsoft Windows operating system, and to simplify setup and use of such computers. Every part of a standard computer and the most common kinds of peripheral devices are defined with specific requirements. Systems and devices that meet the specification should be automatically recognized and configured by the operating system.


  • http://en.wikipedia.org/wiki/ATX - Advanced Technology eXtended, is a motherboard and power supply configuration specification developed by Intel in 1995 to improve on previous de facto standards like the AT design. It was the first major change in desktop computer enclosure, motherboard and power supply design in many years, improving standardization and interchangeability of parts. The specification defines the key mechanical dimensions, mounting point, I/O panel, power and connector interfaces between a computer case, a motherboard and a power supply.

ATX is the most common motherboard design. Other standards for smaller boards (including microATX, FlexATX, nano-ITX, and mini-ITX) usually keep the basic rear layout but reduce the size of the board and the number of expansion slots. Dimensions of a full-size ATX board are 12 × 9.6 in (305 × 244 mm), which allows many ATX chassis to also accept microATX boards. The official ATX specifications were released by Intel in 1995 and have been revised numerous times since. The most recent ATX motherboard specification is version 2.2. The most recent ATX12V power supply unit specification is 2.4, released in April 2013. EATX (Extended ATX) is a bigger version of the ATX motherboard with 12 x 13 inch dimensions. Advantages of having an EATX motherboard is dual socket support.

Mainboard

  • https://en.wikipedia.org/wiki/Motherboard - (sometimes alternatively known as the mainboard, system board, baseboard, planar board or logic board, or colloquially, a mobo) is the main printed circuit board (PCB) found in general purpose microcomputers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals. Unlike a backplane, a motherboard usually contains significant sub-systems such as the central processor, the chipset's input/output and memory controllers, interface connectors, and other components integrated for general purpose use.

Motherboard specifically refers to a PCB with expansion capability and as the name suggests, this board is often referred to as the "mother" of all components attached to it, which often include peripherals, interface cards, and daughtercards: sound cards, video cards, network cards, hard drives, or other forms of persistent storage; TV tuner cards, cards providing extra USB or FireWire slots and a variety of other custom components. Similarly, the term mainboard is applied to devices with a single board and no additional expansions or capability, such as controlling boards in laser printers, televisions, washing machines and other embedded systems with limited expansion abilities.

BIOS


  • Computer POST and beep codes - The computer POST (power-on self-test) checks a computer's internal hardware for compatibility and connection before starting the remainder of the boot process. If the computer passes the POST, the computer may give a single beep (some computers may beep twice) as it starts and continue to boot. However, if the computer fails the POST, the computer will either not beep or generate a beep code that tells the user the source of the problem.


  • dmidecode - reports information about your system's hardware as described in your system BIOS according to the SMBIOS/DMI standard (see a sample output). This information typically includes system manufacturer, model name, serial number, BIOS version, asset tag as well as a lot of other details of varying level of interest and reliability depending on the manufacturer. This will often include usage status for the CPU sockets, expansion slots (e.g. AGP, PCI, ISA) and memory module slots, and the list of I/O ports (e.g. serial, parallel, USB).

  • https://en.wikipedia.org/wiki/OpenCores - a community developing digital open-source hardware through electronic design automation (EDA), with a similar ethos to the free software movement. OpenCores hopes to eliminate redundant design work and significantly reduce development costs. A number of companies have been reported as adopting OpenCores IP in chips, or as adjuncts to EDA tools. OpenCores is also sometimes cited as an example of open source in the electronics hardware community. OpenCores has always been a commercially owned organization. In 2015, its core active users established the independent Free and Open Source Silicon Foundation (FOSSi Foundation), and created another directory on the librecores.org website as the basis for all future development, independent of commercial control. It has been shut down to redirect to a post on the FOSSi Foundation website seven years later in favor of a simple web search, reasoning that "free and open source silicon is no longer a dream".

I²C

  • https://en.wikipedia.org/wiki/I²C - pronounced I-squared-C, is a synchronous, multi-master, multi-slave, packet switched, single-ended, serial computer bus invented in 1982 by Philips Semiconductor (now NXP Semiconductors). It is widely used for attaching lower-speed peripheral ICs to processors and microcontrollers in short-distance, intra-board communication. Alternatively I²C is spelled I2C (pronounced I-two-C) or IIC (pronounced I-I-C). Since October 10, 2006, no licensing fees are required to implement the I²C protocol. However, fees are required to obtain I²C slave addresses allocated by NXP. Several competitors, such as Siemens AG (later Infineon Technologies AG, now Intel mobile communications), NEC, Texas Instruments, STMicroelectronics (formerly SGS-Thomson), Motorola (later Freescale, now merged with NXP), Nordic Semiconductor and Intersil, have introduced compatible I²C products to the market since the mid-1990s.



  • https://en.wikipedia.org/wiki/System_Management_Bus - SMBus, defined by Intel in 1995, is a subset of I²C, defining a stricter usage. One purpose of SMBus is to promote robustness and interoperability. Accordingly, modern I²C systems incorporate some policies and rules from SMBus, sometimes supporting both I²C and SMBus, requiring only minimal reconfiguration either by commanding or output pin use.


SPI

  • https://en.wikipedia.org/wiki/Serial_Peripheral_Interface_Bus - SPI, is a synchronous serial communication interface specification used for short distance communication, primarily in embedded systems. The interface was developed by Motorola in the mid 1980s and has become a de facto standard. Typical applications include Secure Digital cards and liquid crystal displays. SPI devices communicate in full duplex mode using a master-slave architecture with a single master. The master device originates the frame for reading and writing. Multiple slave devices are supported through selection with individual slave select (SS) lines.

Sometimes SPI is called a four-wire serial bus, contrasting with three-, two-, and one-wire serial buses. The SPI may be accurately described as a synchronous serial interface, but it is different from the Synchronous Serial Interface (SSI) protocol, which is also a four-wire synchronous serial communication protocol. SSI Protocol employs differential signaling and provides only a single simplex communication channel.




GPIO / pinctrl

  • https://en.wikipedia.org/wiki/General-purpose_input/output - an uncommitted digital signal pin on an integrated circuit or electronic circuit board whose behavior—including whether it acts as input or output—is controllable by the user at run time. GPIOs have no predefined purpose and are unused by default. If used, the purpose and behavior of a GPIO is defined and implemented by the designer of higher assembly-level circuitry: the circuit board designer in the case of integrated circuit GPIOs, or system integrator in the case of board-level GPIOs.




UART

  • https://en.wikipedia.org/wiki/Universal_asynchronous_receiver-transmitter - a computer hardware device for asynchronous serial communication in which the data format and transmission speeds are configurable. The electric signaling levels and methods are handled by a driver circuit external to the UART. A UART is usually an individual (or part of an) integrated circuit (IC) used for serial communications over a computer or peripheral device serial port. One or more UART peripherals are commonly integrated in microcontroller chips. A related device, the universal synchronous and asynchronous receiver-transmitter (USART) also supports synchronous operation.

It features two bayonet lugs on the female connector; mating is fully achieved with a quarter turn of the coupling nut. BNC connectors are used with miniature-to-subminiature coaxial cable in radio, television, and other radio-frequency electronic equipment, test instruments, and video signals. The BNC was commonly used for early computer networks, including ARCnet, the IBM PC Network, and the 10BASE2 variant of Ethernet. BNC connectors are made to match the characteristic impedance of cable at either 50 ohms or 75 ohms. They are usually applied for frequencies below 4 GHz and voltages below 500 volts


USB


  • USB in a NutShell - Starting out new with USB can be quite daunting. With the USB 2.0 specification at 650 pages one could easily be put off just by the sheer size of the standard. This is only the beginning of a long list of associated standards for USB. There are USB Class Standards such as the HID Class Specification which details the common operation of devices (keyboards, mice etc) falling under the HID (Human Interface Devices) Class - only another 97 pages. If you are designing a USB Host, then you have three Host Controller Interface Standards to choose from. None of these are detailed in the USB 2.0 Spec.The good news is you don’t even need to bother reading the entire USB standard. Some chapters were churned out by marketing, others aimed at the lower link layer normally taken care off by your USB controller IC and a couple aimed at host and hub developers. Lets take a little journey through the various chapters of the USB 2.0 specification and briefly introduce the key points.

  • Mousejack - a class of vulnerabilities that affects the vast majority of wireless, non-Bluetooth keyboards and mice. These peripherals are 'connected' to a host computer using a radio transceiver, commonly a small USB dongle. Since the connection is wireless, and mouse movements and keystrokes are sent over the air, it is possible to compromise a victim's computer by transmitting specially-crafted radio signals using a device which costs as little as $15.




Mouse

  • https://en.wikipedia.org/wiki/Computer_mouse - a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface of a computer.

The first public demonstration of a mouse controlling a computer system was in 1968. Mice originally used two separate wheels to directly track movement across a surface: one in the X-dimension and one in the Y. Later, the standard design shifted to use a ball rolling on a surface to detect motion, in turn connected to internal rollers. Most modern mice use optical movement detection with no moving parts. Though originally all mice were connected to a computer by a cable, many modern mice are cordless, relying on short-range radio communication with the connected system.

In addition to moving a cursor, computer mice have one or more buttons to allow operations such as the selection of a menu item on a display. Mice often also feature other elements, such as touch surfaces and scroll wheels, which enable additional control and dimensional input.




  • Sprites mods - Optical mouse-cam - Optical mouse cam - Are you using an optical mouse right now? Ever wanted to see your desktop through the eye on the bottom of it? Me neither, I already know I have to clean my desktop :-) People get bored sometimes, and when I get bored I sometimes open up stuff to find out what makes it tick. One time, I did this with an old optical mouse. Well, a mouse only has 2 chips inside: the optical sensor and a chip for the usb/ps2-interfacing. I looked up the datasheet of the optical sensor (which is an ADNS2610) and it told me the sensor has a tiny 18x18 CCD, which can be read out using the serial port (the one which normally interfaces to the PS2/USB-chip). So I start Visual Basic (I usually do my stuff under Linux, but I'm no star at using anything graphical like QT or GTK, so for this quick'n'dirty project I fell back in my old habits) and hack something up using a few wires to the trusty ole parallel port. The result: crisp lo-res b&w imaging :-)

Graphics tablet

  • https://en.wikipedia.org/wiki/Graphics_tablet - also known as a digitizer, drawing tablet, drawing pad, digital drawing tablet, pen tablet, or digital art board, is a computer input device that enables a user to hand-draw images, animations and graphics, with a special pen-like stylus, similar to the way a person draws images with a pencil and paper. These tablets may also be used to capture data or handwritten signatures. It can also be used to trace an image from a piece of paper that is taped or otherwise secured to the tablet surface. Capturing data in this way, by tracing or entering the corners of linear polylines or shapes, is called digitizing. The device consists of a rough surface upon which the user may "draw" or trace an image using the attached stylus, a pen-like drawing apparatus. The image is shown on the computer monitor, though some graphic tablets now also incorporate an LCD screen for a more realistic or natural experience and usability.

Display

  • https://en.wikipedia.org/wiki/Display_device - an output device for presentation of information in visual[1] or tactile form (the latter used for example in tactile electronic displays for blind people). When the input information that is supplied has an electrical signal the display is called an electronic display.Common applications for electronic visual displays are television sets or computer monitors.



  • * https://en.wikipedia.org/wiki/VESA_Display_Power_Management_Signaling - or DPMS, is a standard from the VESA consortium for power management of video monitors. Example usage includes turning off, or putting the monitor into standby after a period of idle time to save power. Some commercial displays also incorporate this technology. VESA issued DPMS 1.0 in 1993, basing their work on the United States Environmental Protection Agency's (EPA) earlier Energy Star power management specifications. Subsequent revisions were included in future VESA BIOS Extensions.


  • https://en.wikipedia.org/wiki/Display_Data_Channel - or DDC, is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.The standard was created by the Video Electronics Standards Association (VESA). The DDC suite of standards aims to provide a "plug and play" experience for computer displays. DDC1 and DDC2B/Ab/B+/Bi protocols are a physical link between a monitor and a video card, which was originally carried on either two or three pins in a 15-pin analog VGA connector.

Enhanced Display Data Channel (E-DDC) is the most recent revision of the DDC standard. Version 1 was introduced in September 1999 and featured the addition of a segment pointer which allowed up to 32 Kbytes of display information storage for use by the Enhanced EDID (E-EDID) standard. Earlier DDC implementations used simple 8-bit data offset when communicating with the EDID memory in the monitor, limiting the storage size to 28 bytes = 256 bytes, but allowing the use of cheap 2-Kbit EEPROMs. In E-DDC, a special I²C addressing scheme was introduced, in which multiple 256-byte segments could be selected. To do this, a single 8-bit segment index is passed to the display via the I²C address 30h. (Because this access is always a write, the first I²C octet will always be 60h.) Data from the selected segment is then immediately read via the regular DDC2 address using a repeated I²C 'START' signal. However, VESA specification defines the segment index value range as 00h to 7Fh, so this only allows addressing 128 segments × 256 bytes = 32 KiB. The segment index register is volatile, defaulting to zero and automatically resetting to zero after each NACK or STOP. Therefore, it must be set every time access to data above the first 256-byte segment is performed. The auto-reset mechanism is to provide for backward compatibility to, for example, DDC2B hosts, otherwise they may be stuck at a segment other than 00h in some rare cases.

Other important changes were removal of the DDC1 and DDC2Ab protocols, deprecation of separate VESA P&D and FPDI device addresses, and clarifications to the DDC power requirements. E-DDC Version 1.1, approved March 2004, featured support for HDMI and consumer electronics. E-DDC Version 1.2, approved December 2007, introduced support for DisplayPort (which has no dedicated DDC2B links and uses its bidirectional auxiliary channel for EDID and MCCS communication) and DisplayID standards. E-DDC Version 1.3 from September 2017 contains corrections for errata and minor clarifications.

  • ddcutil - a Linux program for managing monitor settings, such as brightness, color levels, and input source. Generally speaking, any settings that can be changed by pressing buttons on the monitor can be modified by ddcutil.ddcutil primarily uses DDC/CI (Display Data Channel Command Interface) to communicate with monitors implementing MCCS (Monitor Control Command Set) over I2C. Normally, the video driver for the monitor exposes the I2C channel as devices named /dev/i2c-n. Alternatively, there is support for monitors (such as Eizo ColorEdge displays) that implement MCCS using a USB connection. See USB Connected Monitors.A particular use case for ddcutil, and the one that inspired its development, is as part of color profile management. Monitor calibration is relative to the monitor color settings currently in effect, e.g. red gain. ddcutil allows color related settings to be saved at the time a monitor is calibrated, and then restored when the calibration is applied.


  • https://en.wikipedia.org/wiki/Extended_display_identification_data - EDID, is a companion standard; it defines a compact binary file format describing the monitor's capabilities and supported graphics modes, stored in a read-only memory (EEPROM) chip programmed by the manufacturer of the monitor. The format uses a description block containing 128 bytes of data, with optional extension blocks to provide additional information. The most current version is Enhanced EDID (E-EDID) Release A, v2.0. The first version of the DDC standard was adopted in August 1994. It included the EDID 1.0 format and specified DDC1, DDC2B and DDC2Ab physical links. DDC version 2, introduced in April 1996, split EDID into a separate standard and introduced the DDC2B+ protocol. DDC version 3, December 1997, introduced the DDC2Bi protocol and support for VESA Plug and Display and Flat Panel Display Interface on separate device addresses, requiring them to comply with EDID 2.0. The DDC standard has been superseded by E-DDC in 1999.
  • read-edid - a pair of tools (originally by John Fremlin) for reading the EDID from a monitor. It should work with most monitors made since 1996, assuming the video card supports the standard read commands (most do). read-edid is a set of two tools - get-edid, which gets the raw edid information from the monitor, and parse-edid, which turns the raw binary information into a xorg.conf-compatible monitor section (Modelines also compatible with xrandr). As of read-edid version 2.0.0, the lrmi code has been replaced by libx86 code - same syntax, but allows for use on many more architectures. For powerpc, there is a /proc interface, /proc/device-tree/pci/{video-card}/EDID, which you can pipe to parse-edid. Some architectures, AFAIK, may be stuck with only parse-edid. As of read-edid version 3.0.0, there have been significant code rewrites, including a new I²C-based interface that tends to work much better and in many more cases than the old interface (still included). If you had problems before, this will likely fix them.

  • splitflap - a work in progress split-flap display. Each module can flip between 40 unique characters: letters, numbers, and a few symbols. Multiple modules fit perfectly alongside each other to build bigger displays.The primary design goal was to make something that's possible to fabricate at home in small or single quantities and can be customized and built by an intermediate hobbyist at a reasonable price. This meant using widely available materials and avoiding any tooling with a high upfront cost.Following that philosophy, the design uses store-bought vinyl stickers for the letters, is driven by an ubiquitous and cheap 28BYJ-48 stepper motor, and uses common PVC ID badge cards cut to shape for the flaps (though custom die-cut flaps are also available).
