This video show a little game console that I designed around the CH32V003 risc-V microcontroller. The interesting part is that it drives the 240 LED screen directly from 16 pins. The way tri-state buffers work allows to utilize the third state to drive many LEDs with only few pins. On top of that the video explains some of the design considerations of this little project and how get is cheaply manufactured.

You have to excuse the low video quality. I didn't have the HD-camcorder yet when I started the project half year ago.

This video shows the development of a PCB Art badge.
JLCPCB Prototype for $2(Any Color): https://jlcpcb.com (sponsor)
If finally tried some PCB art. This badge for Halloween uses a combination of different PCB Layers to get the colors for the artwork. With some animated LEDs and an buzzer playing sounds it is a nice electronics project. The new ATTiny1604 was used to drive the badge. It is efficient and works well with the coincell battery. You can get this project as a kit from my shop, Happy Halloween:

Vid to watch if you can't fall asleep.
Let me bore you to death with my Ouya controllers unboxing and thoughts on them.
People which were waiting for their console and controllers will understand why I needed to do a 14min video on this.

I got the opportunity to attend some solar safety tests on Cyprus. The tests showed some cutting edge safety technology that prevent rooftop fires. On top of that I organized some unexpected efficiency testing and was surprised about the results.
The conducted tests AFCI and RSD.

In this second part of the CRT BOY project we build the case and optimize the hardware.
A single cell battery with a step-up converter is used to drive the CRT screen. This way a charging a simple board can be added. The resulting handheld looks totally like the original GAME BOY but even more retro. Enjoy!
The latest schematic and some further details are provided here:
