Making of the LED Rainbow Tool

1) Alright, let's solder the LEDs to the perforated plate! I don't have a clue about soldering, but I read an online tutorial...

 

2) Looks terrible. But...

 

3) ... it works. That's all I need. Who cares for the side without light and colours?

 

4) The LEDs are fine. How should I layout the flash circuit? Luckily, I have enough transistors.

 

5) Everything is wired up! The LED is flashing. Fine!

 

6) It works with the new rainbow plate, too!

 

7) This moment had to come. Anyway, I'm scared. It is time to solder the parts without destroying them.

 

8) Done! The flash controller is working, the LEDs are working. I plan to make more LED plates with other colours and forms, so I need to connect the two plates loosely. The flash circuit is meant to be an optional part to place between any LEDs and the battery. What could work here ... yeah, flash fasteners!

 

9) I can hardly believe it! The blinking rainbow actually works, though I haven't destroyed a single electrolytic capacitor. What a glorious day!

 

These are the first two paintings done with the new rainbow tool:
