Battery-powered Arduino compatible control station. This general-purpose device is meant for productivity and wireless control of remote units such as NRFBoyLED. It consumes < 2uA when not in use and < 30mA when in use, so a small 500mAh lipo battery will last for months.

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’.
