Remoticon 2021 // Jeroen Domburg [Sprite_tm] Hacks the Buddah Flower

Nobody likes opening up a hacking target and finding a black epoxy blob inside, but all hope is not lost. At least not if you’ve got the dedication and skills …read more Continue reading Remoticon 2021 // Jeroen Domburg [Sprite_tm] Hacks the Buddah Flower

Ground Off Part Number Leads To Chip Detective Work

Sometimes when a piece of electronics lands on the bench, you find that its chips have their markings sanded off. The manufacturer is trying to make the task of the reverse engineer less easy, thus protecting their market. [Maurizio Butti] found an unexpected one in an electronic switch designed for …read more

Universal Chip Analyzer: Test Old CPUs In Seconds

Collecting old CPUs and firing them up again is all the rage these days, but how do you know if they will work? For many of these ICs, which ceased production decades ago, sorting the good stuff from the defective and counterfeit is a minefield.

Testing old chips is a challenge in itself. Even if you can find the right motherboard, the slim chances of escaping the effect of time on the components (in particular, capacitor and EEPROM degradation) make a reliable test setup hard to come by.

Enter [Samuel], and the Universal Chip Analyzer (UCA). Using an FPGA to …read more

The Most Flexible Synthesizer is DIY, Raspberry Pi

[Ivan Franco] sent us this great synthesizer project that he’s working on. Or maybe it’s more like a synthesizer meta-project: a synthesizer construction set. You see, what Pryth has is a Raspberry Pi inside that’s running a custom distribution that includes SuperCollider to generate the sound, OSC for the communication layer, and a Teensy with up to 80 (!) multiplexed analog inputs that you’ll connect up to whatever hardware you desire.

With the computer inside the box — the Raspberry Pi in question — you can easily make this system into a standalone musical instrument, without tethering it to your …read more
