ESPboy as a tape loader emulator for Sintez - USSR clone of the Sinclair ZX Spectrum 48k, can be used for any ZX Spectrum. Actualy ported TZX-Duino soft

There have been complaints that ESPboy1 is hard to build for beginners and of course that's my fault, I got carried away with compactness and SMD.

But now I decided to go back to the source and finished a simplified circuit on large and cheap through-holes components.
Now you can buy all a few parts for less than $10 and even a kid can solder them. 
It's very hard to go wrong.

The compatibility to ESPboy1/ESPboy2 is 99.9% and an extension slot is provided.

So even on this simple device is available ESPboy AppStore, WebAppStore and in general all software and extension modules of the standard ESPboy.

Thanks to @MLXXXp for helping me design and the whole community for their support and inspiration :)

DIY you first own ESPboy!

Have fun :)

Maybe smart ESPboy flower waterer is a bit overengineered, but it turned out cool
You can set watering intervals and limits on soil moisture, run time, and amount of water supplied. Automatically detects if you run out of water. The RTC3231 alarm clock turns ESPboy on and off, saving battery life. Powered by an external battery, so it's not afraid to leave the sprinkler on for long periods of time. I can add WiFi uploads of all the watering statistics to thingspeak.com, for example, to see on the phone how the watering is going. But perhaps I will add it later. While I'm bored with it)

Absolutely amazing review!
It inspires me to push the ESPboy project further! :)
