Recently I made a camera stand so I can film my hands while soldering and assembling my project (Instructable of this is coming soon). This is a kick-off project to test the equipment! (And I made it a gift for Henk Rijckaert)
It's a 6cm x 6cm x 6cm cube that changes colors based on the temperature!
You'll need the following:
- TMP36 temperature sensor
- RGB led, I used common anode, but can common cathode can be used with a small change
- 8 pin DIP socket
- LP1117t 3.3V linear voltage regulator
- 2x 50 ohm resistors
- 10 µF capacitor
- 4xAAA battery holder (not in the picture)
To assemble the case I've used a laser cutter with one sheet of 30x60cm 3mm MDF and one sheet of 30x60cm 3mm plexi. You don't need the whole sheet, but I had it lying around. Some plexi cement is also needed for making the cube.
For programming the ATTiny85 you either need an Arduino, which is what I used, or a specific ATTiny85 programmer board.
To assemble the electronics you'll need a soldering iron and I've used a glue gun to afix the perfboard to the MDF.
