Introduction: LED Altoids Tester
Altoids LED Tester with 2x AA Batterysupply made of old IDE Cable
Tools you need:
Altoids Gum Tin
wire cutter or caliper
Battery Clip for 2xAA batteries
2 AA batteries
1 old IDE cable
20min of your life ;)
By the way.. I was inspired by this awesome Instructable:
Step 1: Find Empty Altoids Can
I like the size of this one because it fits 2x AA batteries pretty well.
Besides the gum tastes delicious.
*But don't eat all at once..*
Step 2: Find and Dismantle the IDE Connector
If you have a IDE or Floppy Cable, simply dismantle the connector.
Now you should have just the connector with the pins on the back without the cable.
Step 3: Soldering the Pins
First make shure how many hole you will keep for testing.
I left 8 holes and cut the rest with a caliper.
In the picture i drew 5 pins each row (10 holes) depending on how you like it.
You can either cut first and solder afterwards, or solder first and have some grip and space to solder.
I prefer the second version.
Solder the pins on each side and be careful that you don't connect with the other Row.
Solder now the positive wire of you batteryclip to a 68 Ohm Resistor (just in case *thanks for the suggestions*) and connect to other end of the resistor with one row of the IDE Plug, the negative wire to the other row.
Step 4: Test and Glue
Before you glue everything together make shure it really works!
Once glued there is no way back!
I used red hotglue to match the color of the Altoids.
Keep the connector fixed until the glue is cold.
Glue the Batteryclip first, then fill up the empty space as you like.
Check the polarity of the LED(s) you connect.
Now you're good to go.
Have fun with it. I certainly do.
