I have the Bysameyee HD 2MP 2K USB Microscope which was purchased on the cheap, to look at something on a motherboard I could not see easily. It is not high end by any means, but will magnify things to some pretty good detail. It is tough getting to focus, because a little change in distance to the object means a quicker change in focus. Think they call that the Inverse Square rule or something like that. The holding clamp is plastic and may not hold up long term. Probably have to glue the clamp base down to make things easier. The embedded light can be turned off, but it has a blue/white cast more towards the 5K range of the light scale. For under $30 it might be worth a try. However, I think this is geared more towards school children.
