When I flashed my esp8266 it was part of a dps30v5a hack which ironically needs a seperate 3.3v to feed the esp, so I had a buck converter already connected to the power. To guarantee my connections I used that to supply the 3.3v and just used the FTDI for data (commoned all the grounds). Seemed to work OK so now I always use a separate data and power configuration. PCs seem to sustain more damage when they drop power – data is usually recoverable – I use the same principle. The Buck should boost that 2.4v battery supply to somewhere round 3.3v, a little more in line with the spec. In the past – just for giggles – I've used a booster with a single aaa to supply a 5m length of 5050 LEDs … not for long … but quite bright while it lasted. I use a nice little adjustable (1-5v in for 1-12v out) one for most projects now.
Julian help!! I can flash the esp (at least it looks like it did) but it does not seem to transmit (reply back) – I opened lua uploader and clicked restart esp & tried the ip code and it only says sent but theres no echo back (reply) from the esp?!? I've checked it a dozen times and I can't find the problem. I reset and made sure the jumper was removed – so I'm sure it's not in flash mode…
+JulianIlett Great video, a nice project that I can think of all sorts of IoT things to make. I'll be very busy ๐ I know this is an old video so if you haven't already, please get some software to record the pc screen directly instead of filming it…. Thanks for taking the time to make it.
On a ESP8266 bought in 2017, when I try to update firmware, it does not propose to update FLASH, IROM, DEFAULT & BLANK as in this video, it proposes to updarte INTERNAL//NODEMCU only. I have tried this, although the interpreter comes up, it doesnt follow the test proposed to check success a =5 print(a) I am sure it hasnt been fully updated all teh binaries, but I am not sure how to resolve this
Hi Julian im using windows xp 32bit and in Nodemcu when I look in my config I only have the top line with anything in it and that line says INTERNAL//NODEMCU do you know why I'm only getting this please ??
Now I remember why I gave up them. Esp32 was the best move, so much better.
Julian, it's 2019 now and people are still learning to use the ESP8266-01. It would be great if this were updated. Took some fiddling, but this works.
What's the name of the little green pin bridge doodad you used? Do they do longer versions (to connect multiple pins together)?
Thanks in advance.

Thank you so much
Bcz of you my dream of making IoT project come true
The tantalum capacitor is useless if you use battery power, it actually can cause problems when it fails
while using coolterm there was no RX blinking and I couldn't give any At command, what do you think the problem is?
Very useful ๐
Does the 2 batteries have enough volts? ESP8266 wants 3.3V,

do I need a microcontroller?
