One of the school projects that caught my eye was a popsicle stick-encased stereo amplifier with speakers built from used CD cases. Ian has to pay for supplies–popsicle sticks and the CD cases make for low-cost building materials.
One of his students wanted a cheap stereo to take to college, so he designed one for easy construction, affordability, and cool design. It’s all of that. The project is built around a $33 8-watt amp. Blue LEDs give it a cool glow at night. Ian had four students without prior electronics experience build their own and he said they did so with ease.
