i just recently took apart my old Gameboy Color and noticed that at the top of it there are a couple of LED’s. i was just wondering if the Gameboy Color was originally meant to be able to control things remotely with its LED’s.

Look at http://www.farnell.com/datasheets/27736.pdf for a more professional detector. The diode is quite cheap by the way – only ca $3. Its name is HSMS-286K. Get it at Farnell: http://no.farnell.com/jsp/endecaSearch/partDetail.jsp?SKU=3883103&N=401

Mixer diode outta the radar detector, eh?

Ima slap one of these puppies together tonight!

Ugly, but beautiful! I’m wondering if the guage of the copper wire makes a difference? It looks as though this person used a 12 guage wire for the elements. This would maybe make a good detector for tooling around the neighborhood in your car, seeing which neighbors of yours are using an 802.11g transmitter ;). Oh – and put me in for 10 on pete also.

Another good source for these microwave diodes is old radar detectors. Nearly any radar detector that uses a cast metal waveguide horn and mixer housing will have one or more detector diodes installed in their mixer stage.

Some manufactures of radar detectors used “strip-line” waveguides and mixers, so these will have a double-sided p.c. board with
tiny little “pellet”, surface-mounted diodes instead of a 3-dimesional “horn” assembly. These would, admittedly be much harder to de-solder/solder to without overheating and destroying them, but might make for a far more compact antenna assembly.

Standard ESD precautions should also be observed to protect these types of diode/s from static discharge while handling and soldering.

1N5711 schottky diodes will work, and are much easier to find. To drive an analog meter, you’d need to buffer the diode’s output with an op-amp. For a accurate reading in dBm, look into the Analog Devices AD8313/AD8314 series of log detectors.

The main issue, is that this kind of diode are really rare, and hard to find. So don’t dream to much about this.

ByeBye

Teamhackaday.com is down, right when I was about to submit a long post too.

Forwarded this to my brother, he probably will be happy with it :-D

This is a beautiful hack. Thanks, Eliot.

ARRRGH! He doesnt specify EXACTLY which diode he used… I have a box full of thrift-store radar detectors and other door-opener gunnplexers, (all have SIMILAR microwave diodes in them) but theres no way to tell which will work best…
