Fresh hacks every day
[Fede.tft] wrote in to tell us about some work he’s been doing to save battery life for LED dominoes. He originally got the idea after reading this post about the electronic gaming pieces. That project was aimed at the 555 timer contest and therefore, used a 555 timer. [Fede.tft] calculates the battery life for the CR2302 battery in … Read the rest

The lock uses mostly NAND gates and 555 timers to get the job done, which makes it a nice alternative to similar software-based projects we have seen in the past.
The lock has 6 keys on the … Read the rest
Here’s an interesting method of reading data off of a NAND flash chip. Often we see these chips desoldered in order to read and write data, but not this time. This method uses hacked adapters to match the pin pitch of the various chips. Above you see parts of a breakout board cut down to use as wedges. These … Read the rest
Sometimes, a little bit of noise can be fun. This little noise synth called the Nandhopper, is a quick simple project to get started. The parts list is pretty short, mainly material for the sensors and a 4093 Quad, 2-input Schmitt trigger and NAND gate. You end up with an easy to use, fairly small 1-Bit synth. If … Read the rest

The method, which involves overwriting your data with music, is … Read the rest

This hack is fairly straight forward. All it took was someone with steady hands to try it out. The new NAND chip is … Read the rest
