Logic probes can be anything from useful to critical depending on the project, but if you don’t have one already, why not try building one? Instructables has a guide to building a logic probe using a PCB, an assorted lot of resistors, capacitors, regulators, DIP sockets, a 9V battery clip (and 9V battery), and a hex inverter. Instead of using … Read the rest

USB 2.0 FPGA based 24 channel logic analyzer
September 27, 2007 By 13 Comments
[lekernel] sent in his USB logic analyzer. I might just have to build this one for my work bench. It’s based on an Altera Cyclone 2 FPGA and he’s provided full schematics, source and a quick and dirty Linux driver to get things going. The board is nearly all surface mount, but he points out that the entire thing was … Read the rest
