It will; you will need either an external regulator of the sort discussed in the article, or an ESP8266 module like the Wemos D1 with a RAW voltage input that will take approx 5v and regulate it internally to 3.3v

bit late, I know, but that bar had me puzzled too, until I saw a bigger picture; it looks like its just a light bar with a row of leds on it.

still illegible
- slarti.fartfast commented on TechKiwiGadgets's instructable Arduino Metal DetectorView Instructable »
The single coil version of this project is ideal, as the use of a microcontroller allows fine tuning BUT it would be better if the diagrams were uploaded in a legible size, and some empirical tests of its capability shown (e.g. detects a dime from 10cm away)

A good quality article, but at least some indication of capability would be helpful, in terms of e..g. detects a 1 euro coin at 30cm

Good idea. Those joints are going to take all your weight, though, so I'd add a diagonal brace (using perhaps some of that steel strap?), to save the whole thing lozenging if it gets any fore/aft force on it.

Wouldn't it make more sense to put the magnet on the door and the Hall sensor by the solenoid? less wiring and no flexing.

well no, the DIY circuit is hardly complicated! and besides the DIY version can be tuned not only for touch , but also proximity, just by changing the resistor.

It may be a bit late, but I think the problem is that it looks like TomK32 is using an I2C screen (scl/sda) not SPI (sck/mosi/miso/ce)ucglib works fine for spi, on my ILI9341 screen to the ESP8266 I usedsck=d13 mosi=d11 miso=d12 (those are the esp8266 hardware spi default) then ce=d2 cs=d8 d/c=d4 reset=d0the screens are sensitive to power upset on boot, mine was stuck in white screen mode till i put a hard reset into the code.

Sounds like a good project! I'm a bit confused about what scripts the ESP8266 ends up retaining; I see we can nominate a "boot" script which obviously should control all our other scripts; are there any constraints re the lua code we upload? e.g. can our ESP8266 have a web server, or would that conflict with the OTA code?

interesting question - how much current is needed? We don't want the act of measuring a battery voltage to drain it!

FYI those updated tuned lengths are in Lee Hite's very comprehensive website on wind chime construction - http://leehite.org/Chimes.htmwhich also gives details on tuning for other scales.
go and read his post again - look for the bit that says " Lithium battery and charger" - and the protection is built into the battery pack, which is what he's adapting.
