Behold the cardboardy-retro-nessKamil‘s BeatSequencer v1.0. Though the front panel may have some mechanical stability issues, It reminds me of a miniaturized vintage computing giant. FYI – Those 24 LEDs are handled via Arduino’s shift function and the handy 74HC595 shift register chip.
MusicMiK shares his PCB creation process while working on a couple of phaser effects pedal boards. If you’re interested in making your own boards this will of course be of interest. Keep in mind, some of the techniques he demonstrates could be accomplished by relatively simpler means – such as using iron-on transfer or presensitized […]
Alan Parekh, of Hacked Gadgets, write: Using a DVD player screen, a rewired toy keyboard and toy laptop looks like it made a great start to this DIY Parallax Propeller Laptop.This project demonstrates the power of the Propeller microcontroller. Full documentation is available so that you could make your own. “This is a Propeller laptop […]
Simple yet effective, they come in a dizzying array of forms and materials. Vital to so many circuits for storage, timing, and filtration – the mighty capacitor! Download the m4v file or subscribe in iTunes In this installment of the MAKE presents series I explain – how to build a leyden jar, how the capacitor […]
This might be just the thing for a robotics project cancelled on account of – “expensive”. Professor Mason created a quadrature encoder by fitting a motor with 2 inexpensive hall-effect sensors and a small magnet – In this application, two sensors are attached 90 degrees out of phase around the motor. A small permanent magnet […]
(photo from Andy Ihnatko’s 2007 You-Do-It Sale Flickr set) Andy Ihnatko writes about the annual You-Do-It Electronics Store Presidents’ Day Sale, which looks like a great opportunity to rummage for cheap, useful, and unusual electronics: The Sale is a big day on the New England nerd’s calendar. And YDI is a special kind of electronics […]
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 […]
