Using a 3020 Desktop CnC machine to make a mould of a Tshirt shape a viewer asked about - as a keyring. Software used: Inkscape, Universal Gcode Sender (with grbl on Arduino) and jscut. Materials used: Trycut (by Tekwani), Gede Crystal Clear resin and regrettably blue masking tape.

In this video, I connect an 8x8 Neopixel Panel to the esp8266 on a NodeMCU dev board. Lots of fun making blinking lights and shapes. The 8x8 panel is driven from a single IO pin - making it easy to adding to projects. They are also quite widely available. This is part of my video series having fun with the esp8266.

Dropping 6v batteries to 5v for an Arduino Uno - using 2 1n4007 diodes. It can't be done with the onboard regulator with less than 7v. Revealing some of my plans for the esp8266. For detail and a breadboard layout - see http://orionrobots.co.uk/2015/04/04/powering-arduino-uno-from-4xaa-batteries/ I've recently written a book on making robots titled: "Learn Robotics Programming" which takes you step by step through building a Raspberry Pi-based robot and programming it with Python to perform autonomous behaviours. Buying it at https://www.packtpub.com/hardware-and-creative/learn-robotics-programming is a great way to support my channel. More recently I have been building a Robot Arm with the Raspberry Pi at https://youtu.be/MQ6MhoB3PEU ... https://www.youtube.com/watch?v=GdwwRB3dKKE

If you are using the NodeMCU or Esp8266, there being only 1 analogue input seems like a drawback. I wanted to use a 2 axis analogue joystick with mine, and use a simple 2 transistor setup to solve it.
