Fox light

Casing and schematics for illuminating a fox model (fox not included). The casing has holes for two micro switches, the LEDs and a USB-C plug.

I recommend (trans) pride colours (🔵🟣⚪🟣🔵), although they are hardly distinguishable in the picture.

Software features

• 5 Programs (constant, moving light and variation, sinus, random)
• Low power standby

Assembly

1. Print parts. You can get the fox model from Keeya's shop.
2. Flash the ATtiny84. You need an ISP-programmer (or an Arduino board) for that. If you want to compile the software from the source, you do need to add the ATtiny core to your Arduino IDE.
3. Solder the components.
   
4. Screw everything together
5. Add 5mm holes to your fox model where you have placed your LEDs. The fox should fit tightly, even without glue.

Required materials

Electronics:

• 5 transistors with resistors (e.g. 10k), NPN type (e.g. BC547)
• An USB socket or another 5V supply (I used those; screw or glue them to your board)
• LEDs with resistors. I got pink ones from Reichelt. To model is created with 9 LEDs in mind.
• 2x 6×6×12 mm micro switches
• 2x 5×7 cm prototyping boards, and respective connectors (1×3, 1×6). The 1×1 connector does not have any function.
• 3x 1 nF and 1x 1µF (or larger) capacitor

Other:

• M2.5 screws and distance bits (I used those)

Required tools

• Soldering iron, solder
• A 5 mm drill
• A knife (I think the screw holds aren't placed perfectly)
• A 3D printer

Used filament

• Fox: Blend Pearl White (non-transparent white will make colors mor distinguishable)
• Top: Galaxy Black
• Bottom: Prusa Orange

“Fox not included” - Where do I get the fox model from?

The fox model is made by Keeya. You can buy one from his Ko-fi shop.
