Inventors Kit 3: Spin-Art

Posted by Matthew Little on

This time we will use the motor to make a spinning wheel, which you can use to show off patterns you design or that can be used to make 'spin-art'. You will need your wobbly wrobot that we built previously. This time we will not need the nut, as we don't want it to wobble this time! You might also want to use two batteries to make the motor spin faster! Here is the motor circuit with two batteries: I needed to use some tape to hold the connections in place. You will need to cut a disk from some...

It comes as an almost complete board (SMD has all been done) with just the switches and ZIF socket to solder in. Getting started, I first went to the main page for this device on the Proto-Pic website. The main user guide is available here. The unit was dead easy...

Quotation Machine using the CheeseBoard

Posted by Matthew Little on

Setting yourself a small challenge in the form of an interesting project is a great way of learning - even if it involves a fair bit of failing! I set myself a weekend challenge of using our CheeseBoard ESP8266 development board to obtain and display some data from a website using a wifi connection. My original challenge was to show real time data about the electricity supply mix within the UK. As I looked into this problem I realised that it was far too complex for me to start with. So I reduced the challenge to display some data from...
