Ask HN: Great maker projects for 8th grade kids and above?
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?
