Felt covered speakers for 30Watt DIY amplifier

After a long break from doing crafts we are now back with another wonderful project. My son Lee built a 30Watt stereo amplifier during the summer vacation and designed these speakers at school. Finally we managed to find time to complete them and the gluing of felt was a great exercise in being neat. The loudspeakers cost 10 Euro from our local electronics shop. They look, feel and sound great on his amplifier (see a post further down) We will design speaker stands for them to bring them to ear height.

Mini 10W 8Ω speakers for DIY amplifier

Lee-Kuo found a new pair of speakers in our local electronics shop, which gave him the idea to build little speaker boxes and drive them with a self built amplifier. He designed the box with a bass port at school and we did a quick rendering in Cinema 4d to see if it would look good. I cut the wood and sanded it in about half an hour and Lee-Kuo did the soldering and electrical connections. We are really pleased with the results and they sound really powerful.

Mini, miniature golf course

This was another summer vacation craft that Lee-Kuo made. He missed the crazy golf course in Germany and decided to make his own from wood. We found a wonderful set of instructions on the internet from a magazine printed in 1950. Lee-Kuo had so much fun sawing, cutting, sanding, shaping, drilling and gluing. The summer vacation was simply too short so he only completed 5 holes, nevertheless they are superb. click here for the original 1950 instructions

Hole 1, the ski jump

Hole 6, the maze

Hole 11, pinball

Hole 12, diamonds in the rough

Hole 14, foothills
