This post will be updated from time to time, the components might change, so it is up to you if you want to experiment on your own while in the “pre-release” state or wait for a release state. All items get a color status:
yellow = component might change blue = component is final choice, only chance of change is if insurmountable obstacles appear
The prices are those I payed for them and of course depend on the source where you get them. I am not related to any of these shops and I don’t get any bonus or affiliate payments, they are just a suggestion.
NOTE: Not in the list are basic items you will need for sure such as wires, solder, some glue and filament for the printed parts. For the JST connectors I don’t provide a link since there are offers with collections that make more sense including or not including tools etc.
Minimum requirements for ONE blaster, minimum means no audio or visual feedback and no blaster ID, which makes all of this pretty useless but you can fire at a target and the target gives feedback. Actually you just need the IR sender and receiver, one resistor plus the LOLIN S3. But hey, that won’t be fun at all.

Update 2024-03-07:
Since the S3 Mini causes massive trouble with many libs I probably have to replace it again by something else, I ordered some ESP32 WROOM dual core boards to check them out and to compare their behaviour to the bitching of the S3 Mini.
I hope the S3 is still an option in the future (damn, I got ten of them 😉 ) but at the moment it suffers from incompatibility because the development of many important libs is still not aware of it or just doesn’t want to be aware of it.
