All In One Cable For Ham Radio transceivers including Baofeng, Quansheng and many other makes of portable HT transceivers. This adapter incorporates thee functions: A USB sound card to convert the receive/transmit audio from the transceiver to USB, a USB to serial adapter to allow programming of your transceiver from radio software such as CHIRP, and PTT control to allow automatic receive & transmit using either serial port settings (DTR & CTS) or the CM108 standard supported by popular software (including Dire Wolf.) You can use this for APRS, Packet Radio, Winlink, Programming or any other sound card data mode.

Compatible with all portable radios that use the Kenwood Style connector.

This is a Raspberry Pi HAT that implements a PC-style parallel port. GPIO pins are organized as data, status, and control registers. The HAT includes a buffer chip that converts from the GPIB 3V3 logic to signals that conform to IEEE 1284. A 26 pin IDC header on the board connects to your DB25 connector. A parport-gpio driver and device tree overlay integrate the HAT with the Linux parport driver stack.

I wanted to use a parallel port based cooled astronomy camera, but preferred to use the compact and low-power Raspberry Pi over a PC at the telescope. Parallel ports are simple devices. Why not build one?

An open standard for a common interconnect between headsets and radios.

The device is HID mouse controller with 4 buttons. There are: left mouse click, right mouse click, wheel up and wheel down as buttons. Connected to PC by Bluetooth. The controller is implemented as a ring on the hand. Designed for left and right handed execution. The device is based on the Seeed Studio XIAO nRF52840 microcontroller, it has its own battery power supply. The battery is of course charged when the USB cable is connected. Charging is indicated by a green LED. Magnetic cable can be used. Used together with Leap Motion and fingers, it eliminates the need for a mouse in the cockpit and allows hands/fingers to operate the buttons.

A Python wrapper for BookStack's API. It pretty much requires you to build the JSON yourself, but doing it as a hash table makes it a bit easier. I was able to hack together a directory full of Markdown files-to-Bookstack converter in about half an hour. If nothing else, it abstracts away a lot of the boilerplate you'd otherwise have to do yourself.

An alternative PCB pawprint for the Tag-Connect TC2030 pogo pin programming cable.

ArduinoFDC is a sketch that implements a floppy disk controller. It works with Arduino Uno, Leonardo, Nano, Pro Mini, Micro and Mega.

ArduinoFDC consists of three parts:

• A library providing low-level functions to allow reading and writing disks at the sector level as well as low-level formatting disks.
• Integration of ChaN's brilliant FatFS library to provide file-level functions for reading and writing files and directories in a FAT (MS-DOS) file system and a high-level format function to initialize a FAT file system.
• An example sketch implementing ArduDOS, a (very) small DOS environment for browsing a FAT file system as well as a low-level disk monitor to access sector data on the disk, including the ability to transfer whole disks or single files via the XModem protocol.

ArduinoFDC works with double density (DD) as well as high density (HD) disk drives. It can read, write and format 5.25" DD (360KB), 5.25" HD (1.2MB), 3.5" DD (720KB) and 3.5" HD (1.44MB) disks.

This is a playground (and dump) of stuff I made, modified, researched, or found for the Flipper Zero.

There's a lot of everything in here, from customized apps, BadUSB scripts, hardware specs for modders, GPIO interface shenanagains and interface pinouts, hardware troubleshooting, sound and music stuff, and sub-GHz captures and dissections for just about everything. It's an impressive collection.

Gabotronics is a small company based in Lakewood Ranch, FL. We have 10+ years of analog and digital design experience. Gabotronics is recognized by Atmel as a Third Party Vendor. We design and manufacture embedded systems. We specialize in 8-32 bits microcontroller projects, instrumentation and data acquisition, PCB Layout, custom electronic designs and we can provide engineering consultation. Currently we are selling data acquisition development boards, but we plan to expand our product line with all kind of electronics products in the future.

This CLI tool provides an integrated set of utilities to remotely interact with and automate a MicroPython device over a serial connection. This will automatically connect to the device and provide an interactive REPL. No additional serial support software is required. Part of Micropython but can be installed as a stand-alone utility wherever you can install Python and run pip.

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.

• 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!

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.

Transforms tkinter, Qt, Remi, WxPython into portable people-friendly Pythonic interfaces, especially if you primarily do CLI tools. Tries to make it easy to build GUIs for applications, because ordinarily the process sucks. Supports several toolkits, including QT, WxPython, and Remi (if you want to turn something into a webapp); you can switch between those toolkits with a single line. No callback functions, that's all handled for you. Has a built-in debugger.

Glasgow is a tool for exploring digital interfaces, aimed at embedded developers, reverse engineers, digital archivists, electronics hobbyists, and everyone else who wants to communicate to a wide selection of digital devices with high reliability and minimum hassle. It can be attached to most devices without additional active or passive components, and includes extensive protection from unexpected conditions and operator error.

If your Ubuntu machine is having problems with network configuration (Network Manager is refusing to configure an interface for some reason), these tips may help you fix it.
