Fresh hacks every day
[Leafcutter] is big in to making music and has put together all sorts of musical instruments and tools over the years. Recently, he was inspired to make his own piezo crystals, and wrote in to share the results of his experiments with us.
[Leafcutter] is no stranger to messing around with piezo elements, and after seeing [Collin’s] tutorial on … Read the rest
There’s been a lot of stories about arranging solar panels to mimic leaves on a tree, thereby boosting their efficiency. But before reading that story you might want to check out this blog post correcting some flaws in that breakthrough (page is down, here’s a cached version).
Before we go any further, we’d like to point out that the … Read the rest
You know them, you love them, you take them for granted – they are single push button on/off switches. As [Dino] explains in the most recent episode of his Hack a Week series, they are typically implemented in the form of IC logic switches nowadays, but it wasn’t always that way. When they first came on to the scene … Read the rest
Earlier today, [Jack] posted his latest video. He then promptly ran off to the secret Hackaday headquarters to begin work on the next one. Unfortunately there was a weird problem with Youtube which left the video un-viewable. We’ve fixed it now and wanted to let everyone know.

[fpgaminer], [li_gangyi], and [newMeat1] have been working together for the last few months to build an FPGA bitcoin miner that blows GPU mining rigs out of the water in terms of power efficiency. The board requires only 6.8 watts for 100 Mhashes/second, but [li_gangyi]‘s blog says the team expects to hit 150-200 Mhashes with some improvements. That’s efficiency GPUs can’t … Read the rest
