Fresh hacks every day
If your board fabrication and soldering skills are up to it, you can make your own tiny MP3 player. This rendition is just about half again as large as a standard SD card, whose slot is on the bottom of the board seen above. The heavy lifting is taken care of by a VS1011 MP3 decoder which also has its own stereo headphone driver on-chip. There's no display and it seems that most of the 4k of … [Read more...]
[Glass Giant's] wrist-mounted fireball launcher adds a little stage magic to his life. This method of fire production is several orders of magnitude less dangerous than other arm-attached flamethrowers or instrument-mounted torches. The module, which is strapped to the underside of his wrist, stores and lights a combination of flash cotton and flash paper. The two flammables are housed in a small … [Read more...]

This is neither as pretty nor as accurate as a precision scientific instrument, but that doesn't mean it's useless. In fact, it works perfectly well for rudimentary observations. Light is shined through a sample solution, passes through a diffraction grating, then shows up as … [Read more...]
Hackaday writer [Gerrit Coetzee] built a simple clamp to aid in surface mount component soldering. This cheap, easily made device uses gravity to hold tiny components in place. The tip of the bolt is pointed, but gently like a ballpoint pen so as not to harm the components with a sharp tip. Roughly position your component, rest the tip of the clamp on its center, then nudge for final positioning. … [Read more...]
Want to put 100 horses into your golf cart and then take it to the Dragstrip? Why not? [Mac McAlpine] did just that by dropping a 2007 GSXR 600 EFI into a 1987 gas-powered Yamaha golf cart. After the break you can see a video of the test run, as well as an overview of the modifications made when swapping engines. [Mac] mentions that the setup still uses the stock bike chain and jackshift even … [Read more...]
