This shield is used in Tech Explorations “Make an Environment Monitor Gadget” and “Kicad Like a Pro” courses.

Uses Molex Mini-fit Jr. Connectors for a quick connection to build CAN networks fast for teaching with 1 power supply. Part numbers are printed on the silkscreen. Brought to you by the University of Tulsa’s Student CyberTruck Experience.

The next-generation speech synthesizer for the Amstrad / Schneider CPC line of computers.

https://github.com/lambdamikel/LambdaSpeak

This version supports the GI SPO256-AL2 retro speech chip, in addition to the TextToSpeech click board. The SPO256-AL2 makes LambdaSpeak a 100% compatible and authentic reimplementation of the original DK'tronics and Amstrad SSA-1 speech synthesizers. The LambdaSpeak firmware hence supports 2 more modes for SPO256-based DK'tronics and SSA-1 speech synthesis, in addition to the Epson S1V30120-based SSA-1 and DK'tronics emulations. See project page above for more details.

IN-18 One Tube Clock adapter for my One Tube Nixie Clock. These tubes have 1mm pins that plug in to a socket. This board is intended to use female D-SUB pins as a ‘socket’. These are often listed on eBay as ‘1mm tube socket pins’.

The board includes pads for a neopixel and for a current limiting resistor

This One Tube Nixie Clock adapter is for any top-view tube that uses a B13B socket. This includes ZM1020, HB-106, B6844A, B6091, B5092, GN3, GN4, etc. These tubes have 1mm pins that plug in to a socket. This board is intended to use female D-SUB pins as a ‘socket’. These are often listed on eBay as ‘1mm tube socket pins’.

This design controls various sizes of RGB Led Matrix displays using an ESP8266 and the Arduino IDE. A great tutorial for getting it up and running is at: http://www.instructables.com/id/RGB-LED-Matrix-With-an-ESP8266/ The Arduino library is at: https://github.com/2dom/PxMatrix

PCB for FMC Transient Generator, Surface Mount Version

This is an IO adapter board for the Raspberry Pi 3 based on the awesome Pi1541 project. It is currently very much work in progress. A prototype batch of the first revision has been manufactured and is being tested. It is generally working but there are a few minor issues.

Revision 2 is soon to follow!

An ATmega328-based millivolt meter based on a design by Scullcom Hobby Electronics. Uses an LTC2400 ADC and LT1019 voltage reference.

I have fabricated the board at OSHPark, built and tested it - all OK! There are a few changes I’d make to the PCB if I did this again - mainly concerning more convenient connector placement. All the design notes (including code) are available at in my LEAP GitHub repo
