The SheevaPlug is reputed to have a marginal power supply. It seems to be more of an issue for the people in the UK running at 240VAC, and it also seems to be a problem to load the USB too heavily, as happens if you want to add an external mechanical disk....

Those of you who own large 500 watt and higher Astron linear power supplies, and even large HF amplifiers, know all too well that "GNNNNnng" sound that they often make when turned on. This is due to the high inrush (surge) current flowing into the....

To obtain the power supply graphs on the previous page, I didn`t stand outside for two days straight measuring the power sources with a voltmeter. Instead, the circuit itself is able to independently monitor the power sources with the addition of a few....

This is a simple circuit which outputs a voltage which is more than the input. This could be used to power 12v or 9v devices from a 6v system, or even 6v devices from a 1. 5v battery (see below). This circuit uses bog standard parts, without requiring a....
