Glowing cube

Intructables member Alex the Great has a clever Awesome LED Cube project. Use the cube to slow, stop, or reverse time, or even turn ordinary technology into transformers. Your choice. This project looks like a great way to introduce kids to a number of valuable skills we have covered here at Make: Online, such as […]

LED fish = art circuitry

LED fish = art circuitry

From the MAKE Flickr pool Feurig etched a well-planned fish-shaped circuit to hosts a slew of pink LEDs as scales. Great work – though it would be nice to see all those lovely copper traces exposed in the final product. A lot of work goes into designing circuitry and etching your own provides an excellent […]

The PCB as a heatsink

The PCB as a heatsink

While developing the Roboduino, Scott had to calculate how many amps his project could deliver to attached motors. He wrote up his findings (and how he arrived at them) as a helpful article – As a review, the total heat generated by the regulator is just the energy in minus the energy out. This is […]

Dark-detecting pumpkin light circuit

Sayeth the animated, wraithian lab coats at Evil Mad Scientist Laboratories (think: Santa’s worshop, only for Halloween, and evil!): Here’s an inexpensive electronic circuit that you can build to put in your Jack-o’lantern. It provides power to drive a few LEDs at night, and automatically turns them off during the daytime. It’s a simple and […]

Review – The VCO Chip Cookbook

Review – The VCO Chip Cookbook

If you’re interested in building an analog synthesizer then the VCO (voltage controlled oscillator) circuit is the best place to start. Oscillators form the core of the instrument, generating basic waveforms which are then shaped and shifted by accompanying components like LFOs, VCAs, and filters and then delivered to our ears as tasty electronic audio […]
