You're welcome.The ESP WiFi module uses less than 200mA, so just about any 5V supply will do. You might even already have an old phone charger you no longer need. Or look in dollar stores, they usually have them for, er a dollar :-)
Thanks for detailed information, is there a cheap 5V output supply which we can use?

That's an excellent idea! - fractal7
An alternative to routing a groove would be to use two layers of foam board, with the inner layer having spacing to create grooves. It's quite a bit more work, and will take more material, but will add strength the way fractal7 is suggesting. See sketch below. - JC41

I would not connect two outputs. I think that would cause problems for the ESP.Alternatively, since the ESP is a microcontroller like an Arduino, you COULD implement the timer on it. Might be more than what you want to chew though :-) .You will also need to read current time from timer server in the cloud if you want it to be accurate.
Looks great! Love the fused power switch! Thanks for sharing your build!
Thx. Do you know if there is a way to have 2 widgets affected to the same digital pin in blynk?i was thinking having the on/off button and also having a timer for the same outlet.would I short the esp if I use another gpio pin in the same port of the relay?would it be better to program a virtual pin?
There it is... before and after putting everything together... with xtra insulation inside (i put electrical tape on every piece of metal I could see;)I used a recycled fused power switch from a dead projector in which I connect a computer power cable... ur never too safe. ?thx to HarryFun for all his guidance.im gonna make more of those for sure...
How exciting! Glad you were able to solve it.Yes, please post pictures, I'd love to see it!
Thx, it was indeed the case, the 1k was getting in the way of the GPIO 0 and the GRD because I was using the resistor pin to put the jumper cable on. I had to solder another pin on the side of the resistor. Its not like there is a lot of place to solder, but I was able to pull it off, then the sketch was able to upload sucessfully and what do you know, I got a wifi outlet too !! The only variation I did was that I had a fused power box with on off switch recycled from an old projector... so if the S%"$/ hits the fan the fuse will hopefully blow before going to my breaker pannel.Once again, thank you very much!!! ;)PS: I upload pictures once everything in put together.
Thx again Mr Fun.
I've never seen those errors, but one common cause of upload failure is that the ESP is not in program/flash mode.Power off the ESP, connect GPIO 0 to ground, apply power to the ESP. Now the ESP is ready to receive new program.Compile and upload the sketch in Arduino IDE.1 - I don't think Programmer setting on the IDE matters, but mine is set to "ArduinoISP"2 - You should be able to flash the ESP out of the box or any state since we're replacing everything that's on it.3 - As long as GPIO 0 is LOW/grounded during programming and the other pins such as Chip Enable and reset are properly set, it does not matter what you have connected to the ESP.Good luck!
This is the message I get:----------------error: failed reading bytewarning: espcomm_send_command: cant receive slip payload dataerror: failed reading bytewarning: espcomm_send_command: cant receive slip payload dataerror: failed reading bytewarning: espcomm_send_command: cant receive slip payload datawarning: espcomm_sync failederror: espcomm_open failederror: espcomm_upload_mem failed-----------------I've checked and re-checked, and re-re-checked the connections and everything is like ur tutorial, same hardware, etc. Which raise a few questions.1- In Arduino soft, what is the programmer used, mine is set at "AVRISP mkll" by default, is it the good one ? (library, board and all the shebang are up to date).2- Should I be able to flash the esp8266 right out of the box, or I need to pre-flash with another firmware before?3- Everything was connected together before I started attempting to flash, Should I flash, then connect all the component?Thx for your guidance.
