Dave shows how the piezoelectric effect of ceramic capacitors applies to oscilloscope probes, with SHOCKING results.

Dave & David2 have another go at repairing the dumpster dive 46" Samsung LCD TV. This time a further teardown checking out the LCD panel TAB connections, and then reflowing the T-CON Timing Control board. You know how it ends. If you don't like the lack of a happy ending, don't watch.

Dave looks at his 3kW home solar power system after being in operation for 18 months and analyses the results. Original video: https://www.youtube.com/watch?v=VGENVguQQmo Timelapse install video: https://www.youtube.com/watch?v=fQAd7nposJQ How much energy was produced? How does net and gross metering work? What is the payback period? What is solar insolation? The 3kW system uses 12 x 250W LG MonoX panels http://www.solarclarity.nl/wp-content/uploads/2011/09/Data-Sheet-LG-Mono-and-Multi-X-ENG.pdf and an SMA Sunnyboy 3000TL inverter. http://files.sma.de/dl/15330/SB5000TL-21-DAU131211W.pdf Uploading data to PVoutput.org using PVbeancounter and bluetooth from the Sunnyboy inverter.
