I tend to blog about technical topics, but I think this is worth sharing so I'm going to put it here for visibility. I am starting to suspect I may have had Coronavirus at the very end of January, with symptoms starting around the 29th - Coincidentally the date of the first confirmed cases in the UK.
I recently purchased some BlitzWolf BW-RC1 IR Controllers from Banggood to create an IR Blaster between two rooms so I can control my SkyQ box from the bedroom, and also integrate some dumb devices into my home automation system. I tend to prefer local control over dodgy servers in the cloud, and as they're ESP8266 based I was going to flash them with Tasmota - an open source project that adds MQTT and other goodies to enable local control. I was hoping I could use tuya-convert - an awesome tool that fakes part of the Tuya setup process and allows you to flash your own firmware, however it turns out these devices are being shipped with a newer more secured version of firmware that tuya-convert can no longer take advantage of. With little documentation online, I took it apart and attempted to flash it via serial. After a few set backs, it became apparent that the serial pins are broken out via the USB connector (N.B, these are the raw serial pins, there is no real USB interface) so flashing is straightforward and doesn't require any soldering. Note: I only cover preparing and connecting the device for flashing. It's assumed that you already know how to flash Tasmota onto a device once it's connected via serial.
