Volunteer Lab Rat has an interesting project allowing you to build a 3D Scanner out of some common parts. “The following blueprint shows an exploded view of the vital components of the rotating table. I use an R/C servo to rotate the table. It would be easier to construct a table using a steppermotor, but I had an R/C servo on the shelf. The servo cannot rotate a full 360
Julian put together a plan for a RFID zapper, the information below was translated but reads not bad. Project Page. UPDATE: Julian was kind enough to send in a hand translated version. The text below has been changed accordingly. (Thanks Julian) “This drawing represents schematically the circuit board of a disposable camera with built-in flash. Also, the necessary design changes are illustrated. Essentially, the “on-switch†(On-Schalter) must remain closed permanently,
The Hackers Bench has put together an interesting way to hack a cheap remote door bell into a remote control relay. “I was looking for a cheap remote control that would turn on my driveway floodlights from the car. Yea, an IR motion detector would work, and I even tried that for a while. The problem is that we have coyotes, javalina, and other nocturnal creatures that wander around here
For this Flying Crank Ghost project you can either get a kit, or simply follow the instructions to build your own. “This project requires a fair amount of work, but with a few helpers (at least one of which has some woodworking skills), you too can have a ghost haunt a crypt for your Halloween celebration. As always, unless you want to be the ghost haunting the crypt, make
Rob M. from Michigan bought some parts from our store and was nice enough to share the resulting project with us. His son Will has an antique bike on display, it has an old acetylene light on it that hasn’t produced any light for many years. A few well placed LED sure solved that problem. Rob documented the circuit that he designed and is available in the photos below. The
These Halloween Cave Eyes look like a cool project that will spook everyone that comes to your door. Check out the site for full details and PIC chip code. “This is a little microcontroller circuit that has 15 pairs of L.E.D.’s that look like rodent eyes. The pairs of eyes blink in a semi-random fashion. So, what you end up with is 15 pairs of eyes staring out at you
You may remember this tiny Web server. Well I guess small Web servers are the in thing right now . Is that a Web server in your pocket… (well you know the rest). Have a look at this Newton Web Server, not very powerful but it is amazing that it even works! If you are lucky you will even see a page served up by the tiny server by clicking
