Taotronics Mobile Phone / GPS Car Holder Permanent Mount

Summary: If you are the owner of a Taotronics car phone holder and, like me, you like the design and functionality it provides, but dislike suction cup attachments in general and the fact that it occassionally falls off the windscreen when the weather is warm, then check out this project where I convert the suction cup mount into a permanent mount for my car’s dashboard. Super-steady and no more messing around with the unpredicatbility of suction cups. Looks good too, although would have preferred it in black! Read More

Doorbell for the Deaf (or hearing-impaired) – DIY

Summary: The objective with this project was to create a visual signal on my treadmill that would alert me to when someone was ringing the front doorbell. Why a visual alert? Well, because I invariably have music blaring out of my in-ear headphones when I’m running and between that and the noisiness of the treadmill itself, I have, in the past, missed the delivery guy knocking at the front door. It is so annoying to have to go on a treasure hunt just to recover parcels that I could have easily received myself if only I had known that the doorbell had been rung. The final design involved a large red flashing LED to get my attention, controlled by a 556 timer chip (which is two 555 timer circuits in one package) and wired through internal house wiring to the doorbell. The enclosure housing the device was designed to fit into one of the bottle holders on the treadmill display console. Read More

Apple Mac USB Temperature Sensor

Summary: The idea here was to create a temperature sensor that could easily be connected to an Apple Mac computer and have it display its readings inside an OSX application. More a demonstrator than anything someone might actually use in the real world, but who knows, maybe someone out there has a practical need for such a contraption… Read More

A Simple Programming Board for the AVR microprocessor

Summary: A number of the device creation projects detailed on this website use the Atmel AVR microprocessor as the CPU or the ‘brains’ behind the device. However, before one can build any of these devices, one has to be able to get the firmware code on the AVR itself. There are a number of ways to achieve this and the method descibed here is probably not the most efficient way, but it does tend to be one of the less expensive ways of firmware loading and can also put to work some old equipment which you might have lying around earmarked for the trash heap.
