Open source logic analyzer
Posted: February 28th, 2010, 4:28pm MST by Mike Szczys

This caseless logic analyzer can operate at 100MHz and sample 32 channels at once. Better yet, a digital oscilloscope add-on is in the works. The pre-order comes in at $45, that’s a lot of [...]

Posted: February 28th, 2010, 7:26am MST by Mike Szczys
[Anders] tipped us off about his hack that re-purposes a smoke alarm as a burglar alarm. Unfortunately, he came home in the middle of a burglary but wanted to be ready the next time someone tries to break in. By cleverly patching into the test button on an old smoke detector he created a circuit-trip [...]
