This project was designed by hittconsulting. I revised the design slightly to work on our new project boards. You can get the kit from Gadget Gangster and download a PDF version of this howto.
Here's a quick video of the original version;
Warm up your soldering iron and get started!
Step 1: Gather the Parts
- 1x .1 Ceramic cap
- 2x 10uF Electrolytic caps
- 1x 28 Pin Dip socket
- 1x Power connector
- 1x 1n4001 diode
- 1x SX 28 microcontroller (if you buy the kit, the SX will come pre-programmed, otherwise you can download the sourcecode from Gadget Gangster)
- 8x 3mm Red LED's
- 1x Gadget Gangster Boss Board
- 1x 3.3v LDO regulator
- 1x 10k ohm potentiometer
- 3x 10k resistors (Brown - Black - Orange)
Step 2: Resistors and Cap
Add the axial capacitor from s13:t16. This capacitor isn't polarized, so it doesn't matter which way you insert it.
Step 3: DIP Socket
Step 4: Prepare the Voltage Regulator
Step 5: Add the Voltage Regulator
Step 6: Add Electrolytic Caps
Step 7: Diode & Power Jack
Add the power jack under the diode, as shown in the photo.
Step 8: Jumpers
Step 9: Blinky Lights, Set 1
First 4 LED's
Step 10: Blinky Lights, Set 2
Second 4 LED's
Step 11: Potentiometer
Add the potentiometer so the bottom two legs are at T2 & T4. The top leg goes through o3. Use the potentiometer to control the speed of the pattern, turn it right to make the pattern faster, left to make it go slower.
That's it!!! You can grab the kit from Gadget Gangster and the SX will come pre-programmed, or you can just grab the sourcecode there, too.
