After making the speakers we needed an amplifier to drive them so we found this lovely little project on the internet. All the components were easily available and we etched the PCB ourselves. It took 2 afternoons over the weekend to completely finish from etching to switching on. It sounds great and Lee-Kuo is really pleased to have sound from his iPod. For lots more projects including this amplifier click here.

We finally finished hole 13 and here it is. It’s called “left turn” and is not easy to get a hole in one. We took the dimensions from a 3d model we made, this makes it so much easier to find the correct angles and lengths. Until the next hole, good putting.

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.

I find something so simple and easy to make like paper weaving, is great for children to get into mixing colours. I prepared all the strips of paper in many colours and cut the origami paper. My students then weaved the paper and made a frame from popsicle sticks. They look great hanging on a wall.

This beautiful maze was completely designed by Lee-Kuo. He began with a few sketches on graph paper and then decided to use a 20 mm cube grid system with 5 mm thick walls. He drew the maze on 4 separate floors until he had a great pathway to the end. After he had finished the drawings he wanted to make it with matchsticks, we glued about 500 together and decided it would take to long, so I drew everything in Illustrator and printed it onto 120g paper. The result is a wonderfully strong cube maze which gives people hours of fun trying to get the ball through the maze. I am now working on an animated solution which will be on my YouTube channel when finished.
