While clocky runs away from you, this alarm clock can probably strike back. It’s got a pair of basic stamps along with relay’s to control external devices. [Jason] built it from parts he already had, and has visions of it being used for stage fx control later on. For now, I’ll bet that none of the guests will want to attempt turning it off for fear of reprisal by the clock.

Sanfordyne – Scavenged AM Tube Radio
[H.P. Friedrichs] sent in his Sanfordyne project a while back, but It took me a while to appreciate the effort he put in. (Partly because the write up is so long – but thorough) Grab some of your favorite caffeine supplement and take your time reading over the details. Most of the parts were scavenged, and he mechanically etched the pc board with a dremel tool.
DIY A/C Zone Controls
I’ve been planning to computerize my A/C once I buy a house. I stumbled across this simple vent mod. A $10 servo was added and controlled with some off the shelf computer servo controllers. Personally, I have visions of doing this along with several 1-wire temperature sensors. Check out the DIY zoning project for more ideas along these lines.
Accessing The RPM Sensor On A Pc Fan
This one is almost too simple, but it might come in handy. It turns out that Pabst fans (and probably several others) already have the circuitry for RPM monitoring. Pop it apart allow pcb access and add your own RPM sensor lead to the PC board. Not all fans will have it, but it’s a safe bet that it’ll have an RPM sensor instead of a rotor lock indicator on the common PC board component.
My Motors Finally Came Extra
I’ll be hiding out in my workshop tonight, so I figured I’d give you guys a little extra today.
[Ashish] added a servo to his laserpointer/webcam range finder to give his microbric robot the ability to navigate before moving.
[Fredrick] got really motivated, built his own apple I clone and programmed it to play life.
[natetrue] built a sweet wireless motion sensor. [via hacknmod]
[sprite_tm] made a mechanical web page hit counter.
Some people, like [Nuri], really enjoy pain.
Finally, [chad]’s got a different idea on alternative uses for the Wiimote.
Brute Forcing VM Pin Codes
er, [-] sent in this little project. War-dialing is classic. The Scanit is designed for VM wardialing from a cell phone. The interface is a simple sound card to cell phone device made from a cheap car kit.. A laptop does the rest of the work. Apparently the nokia they used responds to sound based send/end commands. (DTMF is easy) I’d like to see a schematic and some source code, but nothing in the project is too terribly difficult.
Adding USB To A Cheap Linux Router
[sprite_tm] usually sends this stuff in, but I discovered that he took some time to hack on a Sweex router. The CPU happens to have an on-board usb host controller, so he added a few components. Now the router can support memory sticks, or possibly become a USB print server. (I can’t say for sure since I haven’t checked out the software myself)
Update: the project was linked in a comment a while back, but we never gave it the attention it deserved. Enjoy.
