Well, as promised in my last CPC2 post, I finished the next build of the CPC2 board and learned a lot of things during the process. Somethings worked, some things didn’t, but every build is giving me a wealth of knowledge of product design, fault diagnosis and rectification work. Yes, de-solder braid really was my […]
Show of hands: how many of you have parked your car in the driveway, walked up to your house, and pressed your car’s key fob button thinking it would open the front door? We’ve probably all done it and felt a little dopey as a result, but when you think about it, it would be […]
For a while now I have been intrigued with Integrated Light Sources i.e. NeoPixels. I knew nothing about them and with the coming of Christmas, I was inspired to take a closer look. I knew I would not have anything in place before Christmas 2017. But there is always next year.
We have the side room (ie including TV) reserved for talks.

This is it. This is the last weekend you’ll have to work on the most explosive battery-powered contest in recent memory. This is the Coin Cell Challenge, and it’s all ending this Monday. You have less than 48 hours to create the most amazing thing powered by a coin cell battery. Joseph Primmer slapped a coin…
This is a small blinky with 20 LEDs powered by one CR2032 coin cell
and with an ATTiny45 brain. The firmware is written in plain C and
compiled with the avr-gcc toolchain. The PCB is a two layer design made
Space efficient daisychained LED placing with shared anode/cathode soldering pads.
Firmware and gerbers are available on GitHub:
Jens has shared the board on OSH Park:
Here is a video of the LED in action:
Today you can buy flashing LEDs; a simple two-lead component that requires only a power supply to produce even flashes of light. They look for all the world like any other LED, though embedded in the plastic dome is an integrated circuit to do all that flashing work. There was a time though when a…

- What new features are on the roadmap for 2018?
- What new features were developed since we chatted in January 2017?
- Under the hood- how KiCad development works
- How can a developer get started helping out?
This is a short 2-minute video explaining what is the Tinusaur project about, who is it good for and what you could do with its microcontroller and shield boards. The Tinusaur is a small microcontroller board with a tiny chip on it. The Tinusaur board is powered by the popular Atmel ATtiny85 microcontroller. It comes as […]
