1A Over Current Protection Load Switch

The Over-current limit load switch project presented here provides full protection to devices and loads from access load conditions. The default current limit is set to 1 Amp, however, this load limit is adjustable from 0.4A to 2A with the help of R4 ISET resistor. When an overload...

Article PC Watchdog – Automatic reset for remote PCs gone haywire

Today’s PCs are quite reliable, but occasionally they hang and stop functioning. Only a ‘hard reset’ will then be able to bring them back to (useful) life. This project takes care of that automatically. Especially handy with remotely located hardware!While many PCs, including...
