A flatbed document and book scanner. Will also scan 3d objects that'll fit under the camera. Minimum of 13MP image resolution (4160 x 3120), can handle up to A3 size documents. Maximum document thickness: 10mm. Scanner camera's height above the document is adjustable. As fast as one second per scan. Portable - can be folded up for transportation. Can detect when you turn the page or change the document, look for the new page, and automatically take the next image. Abbyy OCR functionality built in. Scans to Word documents, PDF, Excel spreadsheets, or TIFF image files. Software for Windows (back to XP) and OS X.
Shows up as a UVC device under Linux (archived), so any image or video capture software that is UVC enabled can do the work for you.
flashrom is a utility for identifying, reading, writing, verifying and erasing flash chips. It is designed to flash BIOS/EFI/coreboot/firmware/optionROM images on mainboards, network/graphics/storage controller cards, and various other programmer devices. Supports more than 476 flash chips, 291 chipsets, 500 mainboards, 79 PCI devices, 17 USB devices and various parallel/serial port-based programmers. Supports parallel, LPC, FWH and SPI flash interfaces and various chip packages. No physical access needed, root access is sufficient (for mainboards, presumably).
FujiNet was intended to be a network adapter that attaches to the SIO (Peripheral) port of an Atari 8-bit computer system but has become an all encompassing SIO peripheral emulator. Designed to physically interface with any 8-bit Atari system via the SIO port with a 3d printed SIO plug. Also has an SIO jack on the back so that other peripherals can be plugged in as passthrough devices. Powered from the Atari (unless it's used on a 400 or 800, they don't supply enough current).
Emulates data storage on cassettes and floppy disks. Data can be stored on SD card or TNFS network share. Emulates the 850 modem. Emulates most of the common Atari printers, but converts files to PDF and saves them. Implements a brand-new network (N:) device.
Implements Bluetooth, NTP, text-to-speech.
RTCs for the RasPi that don't use the GPIO pins but a USB jack are apparently a thing. Battery backed.

Software for using those RTCs: https://github.com/sbcshop/USB-RTC
Another variant of single-board computers that folks like to call Pis these days. Cheap, lots of different sizes and features. Shipped from China. Has both ARM and x86 boards. Not compatible with RasPi cases. GPU acceleration for AI/ML tasks specifically supported.

WeeWX is a free, open source, software program, written in Python, which interacts with your weather station to produce graphs, reports, and HTML pages. It can optionally publish to weather sites or web servers. It uses modern software concepts, making it simple, robust, and easy to extend. It includes extensive documentation.
WeeWX runs under most versions of Linux, as well as macOS, *BSD, and Solaris. Many users are running on the Raspberry Pi. The images on this page and throughout this web site are from sample stations running WeeWX.
Thousands of stations throughout the world run WeeWX, many of whom have opted-in to be shown on our station map.

A collection of awesome security hardening guides, best practices, checklists, benchmarks, tools and other resources.
A collection of cartridges, adapters and replacements for the Commodore C64.
- DiskBuddy64 is a minimal adapter that can interface a Commodore 1541(II) floppy disk drive to your PC via USB in order to read from and write on disks. It uses its own fast loader.
- TapeBuddy64 is a simple and inexpensive adapter that can interface a Commodore Datasette to your PC via USB in order to read from and write on tapes.
- SD2IEC LP is a C64 SD-card adapter and floppy disk drive emulator based on the design by Lars Pontoppidan with cassette port plug. Copy C64 games and programs to SD-card on your PC, put the SD-card in your SD2IEC and load games and programs on your C64!
- Tapuino is a Commodore Datasette emulator based on the design and firmware by Sweetlilmre. Put your TAP-files on an SD-Card and plug the device in your good old Commodore!
- The classic xu1541 is a Commodore floppy disk drive to USB adapter based on the designs by Till Harbaum and Spiro R. Trikaliotis. It connects a variety of CBM drives (1541, 1541-II, 1570, 1571, 1581, SX-64's internal floppy disk) to USB-equipped PCs running Windows, Linux or Mac OS X. This allows for easy transfer of disk images to and from these devices and helps you preserve your old data.
- TapeDump64 is a simple and inexpensive adapter that can interface a Commodore Datasette to your PC via USB in order to dump your old software saved on tapes as TAP files. It is inspired by TrueTape64, a similar project by Francesco Vannini.
- A C64 keyboard to USB adapter based on the design and firmware by Mikkel Holm Olsen. Use the original keyboard with you favourite emulator!
- The SwinSID nano is a replacement board for the legendary SID soundchip of the Commodore C64 based on the design by Swinkels.
- A simple 8k cartridge for C64.
- A MagicDesk compatible cartridge for Commodore C64 based on the work of Marko Šolajić and Zzarko. Build your own cartridges out of multiple PRG-files! Has a 64k variant and a 256k variant.
- A 512k MagicDesk compatible cartridge for Commodore C64 based on the work of Marko Šolajić and Zzarko. Build your own cartridges out of even more PRG-files!
- The FreeLoad cartridge is a simple clone of an Epyx Fastload cartridge, offering a system reset button, a file access activity LED and a disable switch. Load 5x faster from your floppy disk drive, your SD2IEC or your Pi1541!
Keir Fraser’s Greaseweazle is a project for versatile floppy drive control over USB. By extracting the raw flux transitions from a drive, any diskette format can be captured and analyzed - PC, Amiga, Amstrad, PDP-11, many older electronic musical instruments, and industrial equipment. The Greaseweazle also supports writing to floppy disks. The design is fully open and comes with no license encumberment.
A companion code library, Disk-Utilities, converts between flux images and multiple, standardized floppy disk image file formats. These can then be used in hardware floppy emulators, like the Gotek or FlashFloppy, or as disk images in hundreds of pure software emulators.
Very inexpensive! $30us!
The FluxEngine is a very cheap USB floppy disk interface capable of reading and writing exotic non-PC floppy disk formats. It allows you to use a conventional PC drive to accept Amiga disks, CLV Macintosh disks, bizarre 128-sector CP/M disks, and other weird and bizarre formats. (Although not all of these are supported yet. I could really use samples.)
The hardware consists of a single, commodity part with a floppy drive connector soldered onto it. No ordering custom boards, no fiddly surface mount assembly, and no fuss: nineteen simpler solder joints and you’re done. You can make one for $15 (plus shipping).

I might even have the board it requires in my drawers someplace. It looks suspiciously familiar.
I offer the most common X cables that Joe Forster/STA lists on his site, not the X adapters as I have no ability to make the PC boards required. Special cables not listed below will be considered on a case by case basis and if I have the parts to build them.
The prices for the cables are in Canadian dollars and do not include shipping. The cable costs vary as each one contains different components and take different amounts of time to build. Shipping is typically $7 for one cable in a bubble-wrap envelope and multiple cables would mean a different shipping container and higher costs. Since I have no shopping basket, e-finance capability or ordering page, please email me with your orders. All of my cables are verified working under DOS, and are tested using various drives with the latest ROM versions and/or JiffyDOS.

rpi_rtlsdr_weather_station is Python code, based on https://dash.plotly.com to show weather data from a wireless weather station to a web page, served from a raspberry pi. Wireless data from the weather station is received with a RTL-SDR dongle and decoded by https://github.com/merbanan/rtl_433/.
The code is tested with a Fine Offset Electronics WH1080/WH3080 compatible Weather Station (Alecto WS-4000).
