USB 2.0 FPGA Based 24 Channel Logic Analyzer


[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 soldered with a standard iron and de-soldering wick. If you’re looking for a good starter FPGA project, this looks like a good one.

I started writing for Hack-A-Day a little over a year ago. I’ve barely taken a break, but for the next week I’m going to be taking some serious time off on a Caribbean island. Thanks for a great year guys! While I’m gone, [fbz] has kindly consented to take over the reins. I’m looking forward to another year when I get back, but right now I’ve got to finish packing my dive gear.

Add USB Ports And A Flash Drive To You UMPC


[ThoughtFix] sent in our first ever UMPC hack. It’s along the lines of laptop mods we’ve seen before, but he deserves credit for opening up the already tightly packed inside of his UMPC, tapping the USB interface on his bluetooth card, adding a hub and an internal usb flash drive to provide readyboost to speed up Vista.

VUFan – VU Meter


This hack isn’t really all that, but I’m giving it points for creativity. [Christopher] pulled some blue led case fans and used them to make a giant VU meter. Each I/O line has a transistor to drive a TIP120 FET. Personally, I’ll like to see even more of them stacked end to end and pulling fog from a conduit placed behind the stack.

Heat Pipe Wine Chiller PC Cooling


[Gordon Johnson] sent in one of the odder active cooling mods I’ve seen. Initially he planned to use lots of pennies to create the heat pipe, but ended up using some copper pipe with some pennies tacked on to mate to the cpu. The pipe carries the cpu heat from the case into a… wine cooler. Judging from the size, I’d guess that the cooler is one of the peltier variety. To see the final creation, I had to go through the slide show youtube video.
