I have news about my solar setup, summer is over and so is the solar setup :( In part 4 I take a look at the efficiency and look at the performance over the last 60 days.

Thank you Cliff, I also love my mug and the coffee inside of it, it is needed!  :=\

Also a new video :)

The 1800W IH is now boxed up with all power supplies, water cooling, foot switch, current meter and insulated work coil.

Test with using regular mineral wool for house insulation, to insulated the work coil in order to achieve higher steel temperatures.



Here is another try, just with horizontal instead to contain some more heat, accidentally melted some plastic on the enclosure from that

I visited HI Tech & Industry Scandinavia 2019 in Herning, Denmark and while doing so I recorded clips of the most interesting robots, robotics, machines, vision, PLC and machine technology.

You can find booth exhibitions from Schneider Electric, Beckhoff, Flir, MakerBot, Wago, Rhode&Schwartz, Coherent and so on.

I needed a 50A current meter for the 1800W induction heater ( https://highvoltageforum.net/index.php?topic=530.0 ), but had none with the proper scaling. I do however have a large box of 1mA blank scale meters, so I decided to do a video on the following topics:

- Learn how to calculate the shunt resistor for your analog panel meter
- Guesstimate the internal resistance of a unknown meter
- Design custom scales if you have a blank meter or want to use a meter for another purpose than its original.

The HP T-620 Thin Client is a powerful little machine, that with ease can be hacked into using a random 19VDC PSU and run Windows as any normal PC, easy and cheap PC!

This thin client was thrown out, without anything else than the box itself, no power supplies, no nothing.



The port and connector layout from the manual shows that the HP T-620 models needs a 19VDC power supply. A little searching showed that it was not as simple as just supplying it with 19VDC. HP has put in a few tricks to make a "smart laptop charger" so that you can only use their chargers.

The "smart laptop charger" restriction can be bypassed with a simple current limiting hack as per this little schematics. All credits for this hack goes to:  http://nerdipedia.com/wiki/tiki-index.php?page=Smart+laptop+charger

This is a Aethra Colour CCD #Webcam that was part of a system made for remote #medical diagnose / consultation for patients in remote locations.

The system was mounted in a car to be mobile, so a driver could visit patients and make a call to the doctor do complete the consultation within the patients home. The system was driven by a #embedded PC with a complete circuit for the interface, audio/video and running all peripherals on a RS232 daisy chain. The whole setup used some kind of GSM link to transfer the video and audio signal, seemed to be a very expensive and complex setup.
