More small steppers
The output of my stepper motor feeds into a gearbox which I’ve been told has a ratio of approximatly 64:1. During the research of this project I came across a discussion about why the gear ratios were not exact nice

Arduino Micro Review
The Arduino Micro is one of the newer Arduino models but it does not get much of a mention. Like the Leonardo it has a single microcontroller chip, the ATmega32u4 which is an 8bit controller with 32K of Flash and

Small stepper motors
For my clock project I needed to control the position of the hands. My options were continuously rotating servos or stepper motors. I found some small 28BYJ-48 stepper motors and gearbox with ULN2003 driver boards on the internet so I

Smart?
Back in Nov 2012 I backed a project on Kickstarter for a small Arduino like microcontroller system called “Smartduino” which I hoped to use for an internet connected humidity monitor. About this time last year I was expecting to see

Silly Clock
Whilst watching the Mr Silly, Mr Men episode on TV, I noticed he had a rather splendidly silly clock. Research I was having a think and concluded that such a clock could be made and could also be designed to

I2C Mini Shield
The proto shield I’d wired up for the LCD experiments was getting a bit full and I needed to wire up my rotary sensor board so rather than try and add yet another item to it I thought I’d make

Double Height Letters and a hidden hive of tech in Westminster
On Monday night I got to attend the London Arduino Meetup, this group is a mixed bunch of beginners and enthusiasts explaining and learning about using the arduino in their projects. The session was based at the Westminster Hub, a

A little venture in to electronics – Mechanical prototyping
Following the connection of the mouse and LCD to the arduino, I needed to have something physical to do further testing on. I wanted a design that would require the minimum of machining and would fit with my existing angle
