ir_tx_serial

Hello! How do I get the ir_tx_serial, or make it myself? I read through the webpage and couldn't find anything (it's probably on there but I couldn't find it)

Hello. You can follow the schematic schem.jpg and flash the MCU with ir_tx_serial.hex, then connect the RX/TX serial lines to a TTL USB-serial cable.
The critical component is the 10MHz oscillator, which is needed for the precision timing.

Perfect! Thank you so much for your quick reply! Hopefully the tariff situation gets figured out.

Shipments to the US have resumed but only for insured parcels, which are really too expensive for anything sold under $50.
Hopefully the cheaper mail service will resume soon.

In the meantime, if you're experienced with SMD soldering I'd recommend building an ESL Blaster instead, all the files are provided. It's faster and easier to carry around :)
The ir_tx_serial adapter was more of a quick hack from parts I already had.
