As a father of a 13-year-old kid, I tried to do my best to initiate him to different aspects of life. It could be watching a documentary about black holes, building coffee table or just enjoying a simple walk in nature.

I asked to some friends if they have great project idea that could be done by an 8th grade kid with or without support. I personally like to do it with him as it is a privileged time to build something together (for me) and learn new skills (for him).

The purpose of this thread is to assemble some ideas for Christmas presents.

I’m starting…

1. DIY LED Christmas tree kit for soldering (https://www.az-delivery.de/en/products/diy-weihnachtsbaum-kit-alles-inklusive-versandkostenfrei)

2. Software Defined Radios kit (https://www.rtl-sdr.com/about-rtl-sdr/ and https://www.amazon.com/dp/B0CD7558GT)

3. DIY Internet Radio Alarm clock with touch screen control (https://www.az-delivery.de/en/products/radiowecker-mit-dem-az-touch)

Any other ideas or suggestions?

You can have a lot of fun with a tiny traffic light using an Arduino and three different color lights. There are bunch of things you can do to build on it.

- 3d print a stand (here's one I did https://github.com/SalvatoreT/howmm/blob/master/week06/Traff...)

- incorporate an infrared sensor + infrared light to simulate triggering the red -> green flow

- make an intersection with each of the lights working together to show the right thing at the right time

- add a crosswalk
