Fresh hacks every day
[Jim] just finished restoring an old Seeburg USC1 jukebox for his father using an Arduino, replacing an electromechanical rats nest of wires. The stack of 45 records were replaced with an Arduino Mega 2560 with an Sparkfun MP3 player shield, and he jukebox lights are now controlled with 74595 shift registers. Because his jukebox isn’t taking in money, the … Read the rest
As a student of MIT, [Jed Storey] has access to a ton of machine tools, so he decided to build an electric longboard with hub motors by hand. He wound up re-doing a lot of his project, so we can commiserate with him on the trials of R&D.
Inspired by the BWD scooter, [Jed]‘s longboard uses hub motors … Read the rest
[Grenadier] has a thing for the high voltage and, as you can see, he’s found multiple ways to build the icon of HV toys - a Jacob’s Ladder.
The three look similar, but they use different means of generation the voltages necessary to get a spark to jump through the air. The exhibit on the left uses a neon sign … Read the rest
The Arduino has been used for many purposes, and “shields” are available to make many common tasks easier. However, [Nick] wanted a stackable motor driver shield, so he build one himself!. There are many motor driver shields available for the Arduino, however, there aren’t any that allow one to drive as many motors as were needed for his project, … Read the rest
[Stynus] was frustrated with the fact that he would have to flip his PCBs over mid way through the exposure process, so he decided the best course of action would be to build his own double-sided PCB exposure box.
He scored some UV LEDs on eBay, and after waiting a few weeks for PCBs to arrive, he was ready to … Read the rest
