Introduction: Simple LED Tester in a TicTac Box

A very simple project, all you need is a transfer cable, 2 AAA batteries, short of wire to connect the batteries and lot of glue...........All details are in sketches.......

Step 1: Materials and Prepation

If you own an old PC of the days of 90's you will find this trasnfer cable in the specific controllers of Serial or LPT ports......Never throw away something you will need it a decade after....hehehe

Step 2: Transfer Cable

Ok, now sellect the red ribbon cable and the next one. Don't cut the rest of them because someday you will need them to expand my work and make it also a circuit or continuity tester...

You will need a lot of hot glue (if you own a glue gun) or just any glue.

Step 3: Finishing the Job

Always have in mind when you do mods and etc, the result must be perfect functional and beautifull. So some details with the cover and the perfect job is done.....

Step 4: Always Remember Our Supporters

neat... but why not just carry around a 3v coin battery? I have a bundle of CR2032 's and they work perfectly for testing LEDs, assuming the LED is rated for lower than 4V.

You have right, but i had these batteries now, and the device with button batteries maybe has not the need weight....:))))....but is a good idea. Also you can add a 500Ohm resistor at the + edge of the cable to have better results even with low voltage LEDs....

thats what im talking about buddy. HEL.L.U.G. i like the build like the notebook pictures. im going to start this build in a little bit. only im going to use some stuff thats already made like a 2 AAA holder outta parts ive salvaged. but i need this for a led project im working on. i ordered a bunch of surface led's from china. and i wanted to test them before i make it and solder a bunch and find out one or 2 are bad. (ive had previous times of buying 1000leds where a handful were bad)

dont forget to vote in the burning questions round 4. read my entry's and if you like it vote for me..

And don't forget. U can use also 2 more cables from the rest in transfer cable to make them test transistors or other PCB parts. Of course you have to do some extra mods.

Thanks ! Iwas boring to write in computer and i had bought some years ago a pen tablet made by ACECAD model A502, very useful tool in seminars. I found it dusty on a shelf and i use it.......
