DIY for Electronics
While playing with the first prototype I noticed that having just one sound is quite boring and doesn't allow to distinguish visitors with their different ringing habits.
Driven by the need to control a big lamp for time lapse shooting with the SmaTrig I designed a compact power switch useful for DIYers and electronics hobbyists. In the following I'd like to share with you the thoughts and ideas that went through my mind during the development of the device and provide you all data necessary to build your own switch.
Read the following if you are an electronics hobbyist and need something for occasional use. This short article describes how to build your own super simple vacuum tweezers at virtually no cost. It's perfectly suited for positioning small SMD resistors or caps and works much quicker than conventional tweezers.
This article describes how to build an extremely compact converter circuit built around the MAX232. With a size of just 14 x 17 mm (0.55 x 0.67 inch) the PCB is small enough to fit into a D-SUB plug housing
