A first look at the Soulsby Synthesizers miniAtmegatron.
The miniAtmegatron is an Arduino compatible shield in kit form. All the parts for the shield were included, along with some (very) basic instructions. Here’s some quick thoughts on the assembly of the miniAtmegatron:
- Have a fine pencil/conical tip for your soldering iron, and hopefully very fine (small diameter) solder! (more on this below)
- Other things you’ll need: Arduino Uno or compatible board, soldering iron, wire cutters, mono 1/8 inch/3.5 mm audio cable, computer for uploading the source code & libraries and USB cable, optionally some machine screws to hold the shield to the Uno.
- Use the parts list as the order of assembly, i.e. proceed down the 1st column (left), then 2nd column and so on.
- Warning: the pitch of the leads from the RGB LEDs is tiny! I used a very small screwdriver type tip on my soldering iron, and still made a solder bridge between two of the leads on each LED. After unsoldering with a solder sucker (solder braid/wick was too difficult for me to get in there) I had to switch tips to a fine pencil one, and even then it was tricky, even with .38 mm (.014 in.) solder.
- Some type of magnification will not only help double check your soldering of the LEDs, but to read the values of the caps (black on dark blue, small font – luckily there’s only 3)
