Don and his wife have a two year old daughter. They’re trying to teach her the concept of time, and get her to understand that, perhaps, one o’clock in the morning is not the perfect time of day for play! To help with this, Don has taken an off-the-shelf clock, hacked it around with a Dremel and inserted a ShiftBrite bright LED as a backlight. He’s then hooked it up to a Raspberry Pi which is coded to tell the ShiftBrite what colour it should be depending on the time. Their daughter then knows to associate specific times of day with a colour, like red for sleep, yellow for play. It’s a lovely idea and you can find out more about it on his blog.
Over at Dexter Industries they wanted to control a vintage Lionel trainset from the Pi. For this, they used their Arduberry board (which brings Arduino-compatible control to the Pi) and some standard software and custom code. Read how they did it here. You can see a video below.
Linux User and Developer has interviewed maker Dan Aldred about his PiGlove project. It’s a glove that has buttons in the fingertips that send commands to an attached Raspberry Pi. We were lucky enough to have Dan at the Big Birthday Weekend, and I hope lots of you saw the PiGlove! Read the interview here.
Trevor Appleton has written another of his great tutorials in which he takes you through a Python program. This time it’s to solve the “three doors” or “Monty Hall” problem. You are presented with three doors and have to try and find the car behind one door. It’s a pretty well-known puzzle, which makes it excellent fodder for a tutorial! Read it here.
