Dave turns a low cost reptile egg incubator into a decent 2degC to 60degC lab thermal chamber.
Throw in a Rigol oscilloscope, an Arduino, and a few multimeters for good measure.

The model used is the HERP Nursery II, also known as the BCR-25 Wine/Beer chiller and Pie Warmer.

EEVblog #98 – Microsoft InstaLoad Battery Technology – Patent Busting Time?

Microsoft’s new Instaload battery technology allows batteries to be inserted into a product either way around.
Is it one of those brilliant “why didn’t anyone think of that before” moments, or just another silly patent on a really obvious idea?
Is it workable in practice?
Can YOU bust the patent by finding prior art before 2006?

See the Microsoft Patent here:
