I have a few of these little counters on hand and decided to mod a few. One I have at my office sat on my desk, and another two I'll be sending out in the wild. My original intention was to mod a bunch of them and sell them to potential radmon.org users as a 'works right out of the box' counter submitting to radmon.org. I changed my mind after realizing they take a lot longer to actually mod than I initially thought (because I'm doing a much better job on these than the first), and that recently a version of ESPGeiger firmware was released with a bug that made them unable to update

I couldn't wait to tinker with this so I decided to mod this in lieu of getting the ESP-12 modules and programmer. Using a scope I found the connection points I needed, Soldered some wires on. Soldered a Wemos D1 Mini clone on the other end, installed ESPGeiger 0.7.0, and boom! Literally as simple as that. Using the scope I checked the ribbon cable pins one by one and found the pulse coming from the PSU board. I didn't want to solder right on the ribbon, it looks janky already, so probed about and found that it is connected to L12. The MCU side of the inductor is where I soldered the pulse

Yaorea YRG01 I bought another cheap Chinese counter from Aliexpress and I am impressed, especially for the price of £27 shipped to my door. Despite its cheap appearance it actually offers a lot of bang for buck. I haven't looked into it closely, but there seems to be a lot of attention to detail, and I reckon whoever designed this really gave a damn about it. 😄 It came up in suggested products on Aliexpress and I wouldn't have bothered about it if not for the fact that someone reviewed it and posted pictures of its insides. "Okay, a glass tube... Ooh a separate PSU board with a big hunking
