There are a lot of cats around where we live and some are agressive towards our pets. So here’s a description of a successful project to deter them from waiting outside our cat-flap to beat up our guys.
Flight Trim
A present for my daughter which turned into quite an enjoyable little project with a good outcome.
A Line in the Sand
Drawing in sand – it’s “just” a ball bearing moving around a circular, sand-covered tabletop using a concealed magnet – how hard can it be?
MK14 meets 7Bot
Programming this old computer by hand proved tedious so I decided to try a robot arm instead.
Board Anyone?
Making PCBs used to be hard. But now I’ve found EasyEDA and it’s great. Here are links to some boards I’ve made. So what’s stopping you. Get making!
A Little Logger
A quick route to a wireless data logger for testing ways to detect light levels outside
Non-Vesting Share Options
Stock options are a great way to reward employees and non-vesting options are the best kind for everyone – the company and the employees.
Single-Arm Robot
A single-arm SCARA robot which I intend to use to automate game playing on a smartphone – one day!
Auto Reminder Watch
Auto Alarm Watch to remind kids about music lessons and the like. When in range of a suitable Raspberry Pi running the calendar connection software the watch gets new time alarm settings automatically via Bluetooth Low Energy (BLE). It then vibrates discretely when the time comes to leave for a music lesson. It is also a binary display watch.
