Hi!True, I am using a 3.6-4.2V Li-Po battery, all the circuits are running at 3.6-4.2V instead of their intended 12V. And yes, something like an OPA2134 IC would be a lot better, I just used the ICs I had in hand. This was my first pedal and because the circuit was just what I had, I made this instructable into more of a general guide.Cheers.

I think it is your voltage regulator then:I looked at the datasheet for LD33 (https://www.sparkfun.com/datasheets/Components/LD1117V33.pdf) and the quiescent current (current when not doing anything) is 10mA! that's a lot!I used a HT7333 LDO and looking at it's datashet (http://www.angeladvance.com/HT73xx.pdf) it only has a quiescent current of 4-8µA That's a big difference...A 50mAh battery would last for only 5 hours with the LD33 (50/10=5), but with the HT7333 it would last over six thousand hours! (50/0.008=6,250)

You could try adding a Serial.print statement after the line that says ESP.deepSleep . If the serial does print, then you know that it's not going into deep sleep. It's hard to know what's going on without measuring the current...

Yep, for storing key presses...

🤔?Maybe it's not entering deep sleep? Mine lasts for around a month on a 50mAh battery.Have you tried measuring the current drawn? It should be around 70-300mA while operating and only 20uA in deep sleep.

Could you show me your config.jsn file?

I haven't tried this project yet, however the process should be the same, only changing the PIC for an ATtiny and rewriting the code..

Have you edited the config.jsn file?It's failing to parse which means there's probably a syntax error in the json file. It should look like the one on https://github.com/Gangster45671/IFTTT-Dash-Button/blob/master/data/config.jsnI would have a look at the file and check for missing commas, quotation marks and similiar.Hope it works out!

Maybe I forgot to include the SPIFFS data on the bin file. Could you try compiling the code with Arduino IDE and make sure to upload the SPIFFS folder?
