Mike is just controlling a CNC over the web with an iPad, no biggie – 

Controlling my cnc over the web with my ipad so I mocked up a powertail with an arduino to turn the spindle on/off. Took the original housing off and it fits easily into my adafruit arduino case. Matt Ratto made an on off button for me in processing that can leave on my desktop and click remotely.

Dan has taken an Ice Tube Clock, added a Roving Networks WiFly (RN-134) module, and wrote some firmware to add some more features to the clock. He has added time synch, weather data display, and even a Twitter display. He currently has it setup to alternate between the time, the weather and a Twitter message.

PC Fan Repair

I have changed out quite a few fans over the years, you know the ones that I’m talking about, they make your PC sound like it’s a jet engine on takeoff. A few times I blew the dust out of the fan, pried the fan blade off and dropped a few drops of oil into the fan shaft. This seemed to always fix the problem but in my case it always turned out to be a temporary fix since the squeal usually came back after a few weeks of operation and when I opened it there was a bunch of black gunk in the shaft. I think I see what my problem was after reading this PC Fan Repair post from hacklordsniper. I should have used bearing grease and perhaps cleaned the fan assembly better. Seems that he is quite a bit more invasive than I have ever been since he utilizes the bath tub to clean fans and other electronic parts.

“You will need it later. Remove the rubber seal, then use tweezers to remove white lock and a small rubber seal again. At this moment the fan will fall apart and you will see why it does not work. Clean all parts, apply ball bearing grease (not regular one, but the one designed for small bearings) to axle and top and bottom of fan. Reassemble and test”

Here’s an article that presents a rather innovative look at how to spoof magnetic card readers. The spoofer uses an atmega168 connected up to an electromagnet. The article has the source code, hardware schematic and action shots, don’t miss it!

PIR Motion Detector

This project demonstrates how pyroelectric IR sensor can be applied in the detection of moving object. Passive IR detector does not emits any IR light by itself. It is triggered by the variation of IR light that comes from warm & moving objects such as human body. Dogs, cats & other household pets have smaller bodies & do not radiate sufficiently strong IR to trigger the detector. Therefore it is pretty well immune to false alarm caused by pets.
