The Rad-O-Matic

A friend and colleague of mine handed me a LilyGo T5 a couple of months back (We sometimes trade electronics “overstock” resulting from getting over-excited during late night shopping sprees on AliExpress). I stuffed the T5 into my bag and mostly forgot about it until a few days ago. The device is marketed as a digital price tag, but since it has a capable onboard microcontroller (ESP32), SD card support, an E ink display along with WiFi and Bluetooth capabilities, you can use it for so much more.

The Automaton

“The Automaton” is my take on how to do a low budget robot controller. Tech specs 6 - 45V input voltage range. Support for up to 32 servos with a maximum total current draw of 6A at 5V. 24Hz to 1526Hz PWM controller with 12 bit resolution. 240MHz MCU with WiFi and Bluetooth. 9DOF sensor fusion IMU that outputs absolute orientation angle at 100Hz. FTDI programming header. Expansion header with 14 available GPIO pins.

Tiny robots

Inspired by the last local robot tournamet at Omega, the Norwegian initiative Lær Kidsa Koding and a few discussions at my local hackerspace (Hackhem) I decided to revisit the BBC Micro:bit platform to see if it would be suitable as a mini sumo controller. The idea was that it would be really cool to attempt a design of an entry level mini sumo platform, that used commonly available parts, didn’t cost an arm and a leg, was easy to build and easy to program.

You know you want it

After having wanted to get into kit making for some time, I finaly decided to give it a go. This year, I had a few Nixie clocks on display at Trondheim Maker Faire, and later also at Oslo Skaperfestival. The clocks generated enough interest to justify a limited run of kits. I am now offering a Nixie Clock kit in two versions. A “Full kit” version that contains all necessary parts for the clock.

If You’ve got one of these at home…

Norwegian Spar 7 machine.

You will probably want one of these… Spar 7 replacement boards.

I made a new batch of these a few days ago. Initially I thought that I had lost the gerber files and the Target 3001 design files, but I was fortunately able to locate them in one of my old backups. If the files had been lost, I could easily have redesigned these boards, using SMT components in order to make them even more compact.
