great video man !!! thanks for the direction .. the giggle at the end when it lights up , priceless hahaha .. good job on the kits cant wait for mine to show up
You mentioned around 1 minute and 35 seconds that you need to program the 4313 chip. If I buy one from you does it come pre-programmed, If not how do I do that?
The exact value is not too important. The power supply chapter of app note Atmel AVR040 has more info. In my opinion, the capacitor adds a small delay to the chip's power on time so the chip isn't slammed with voltage too fast. Crazy ripples ringing through the wires, etc.
NOTE: it is unwise to solder the ATTINY IC directly to the board. Should it be faulty/glitchy, you’ll have a hell of a time removing and replacing it. So. Go to Amazon or wherever and buy a 20 pin IC socket and solder that in place then plug your ATTINY into that.
The IC socket adds to the chip height and may not fit in your armor. If you run into a situation where the chip is zorched 🌩 contact me and I'll get you fixed up.
I sell the kit for $20 on etsy, free shipping. Pick Mando from the options. www.etsy.com/shop/WestabyElectronics Kit includes the custom parts made by me. I also give you a 1-click shopping list to order the remaining parts from mouser. Current price on those is ~$26 shipped.
If you purchased my kit, then you already have an attiny4313 chip. If you are programming your own chips.... well... the attiny2313 has half the flash memory as the attiny4313. The sketch compiles to around 1k to 1.5k (depending on the code version you get) and will fit on the attiny2313, just select the appropriate options in the arduino ide. The difference between Attiny2313 vs 2313V vs 2313A are voltage tolerances and speed ratings. If you are more curious, google 'attiny2313v summary pdf' to get a shorter datasheet from microchip for easy comparisons.
Dustin, do the symbols on the 7 segment displays have any meaning? Just curious.
Yes. I have a write up on my blog. Here is a link www.westaby.net/2023/02/boba-fett-chest-display-circuit-an-in-depth-analysis-part-1/
To be safe, when you test your led bar graph, it’s best to use a 470 ohm resistor or higher to avoid zorching your segments.

Yes, comes pre-programmed. I have some older instructions on github if you are curious about my process. github.com/thatdecade/Boba_Fett_Chest_Display
The capacitor you show has a code of 334, which is not a 0.1uF, but a 0.33uF. If a 0.1uF is the necessary value, the code on the cap will be 104.

Thank you for this very informative and awesome video.

How much do you sell these for. Need a Mandalorian boba fett version

hi dustin sorry a little question, what's the difference using Attiny2313 - 2313V - 2313A? because here it is difficult to get Attiny4313

Is it possible to make this super tiny, like 1/6 scale tiny?
Sure. They make LCDs that small, but the control electronics will be larger than that, so they will have to be housed elsewhere.
