Hey All,

I picked up this novel little ESP8266-12f development board, I quite like it. It is programmable through the Arduino IDE and breadboard friendly. Thought it might be useful for some of you.

I got a 10% off code from the seller and put it in the video description if you are interested. There is no incentive for me to push this board over others, it is just the first ESP8266-12 I have tried and similar boards are available.

Questions/Help  - 
 
Does anyone here have a lot of experience with electronics design? I am a bit stuck with a board design. Here is the problem.

Scenario:
I am making a shield for an Arduino Nano that includes a battery, charging circuit and a boost chip to output 5v.

To detect when the usb is plugged in to the nano I can only use the 5v pin (as far as I know) when that happens I would like to shutdown the boost chip and enable the charging circuit.

When the USB is remove I would like the boost circuit to activate and the charging circuit to deactivate.

I my recent streams I can do this to some extent by having an on-off switch on the battery and preventing 5v going into the boost converter and also preventing the boost output feeding into the charger. However, that doesn't stop the use from switching on the circuit manually while the USB is plugged in.

My work around it to have a USB connector on the power shield but that will still not fully prevent the PEBMAK (User error) effect.

Any ideas? I realise that this is tough without diagrams.

+David Watts also yes if compare 5V and 5V that'd be useless but i was thinking you could compete 5V and batt+ (4.2 or whatever). but idk. still brainstorming/circuit drafting over here :)

Thanks for all the help on the live streams, I am getting there with the nano shields. Still some work to do on the shutdown circuitry, VIN does not come from the USB so I need to have a rethink.

Hey All,

I have been playing with some wood filament. Have you had any experience with with the FormFutura stuff or similar?

+Tim Visiblé Yeah, the colour saturation is a little high in the camera, it is much more subtle in real life. I am going to have to try out the fish, I have a few just not in wood.

Interesting idea about aligning the infill, I bet that can look really cool.
