In most cases, you measure current by converting it into a proportional voltage and then measuring the voltage. Figure 1 shows two typical methods of making the conversion. In one method, yo... Read more
I published this schematic long ago in this article: Adjustable power supply and since then I made some improvements in PCB to make the board as small as possible. The idea is to be easy to... Read more
In this post we show you how to make a small and useful Arduino DMX512 controller, which can use by example to handle a smoke machine with DMX, or as test equipment, etc… We can use Arduino... Read more
The Tog base module contains a densely packed PCB assembly, battery, and modular expansion bus in a ultra-small plastic enclosure. The base module can operate standalone with no additional c... Read more
