JULABO immersion circulators for controlling temperature +20 to +150 °C in any bath tank up to 50 liters. Parts that are immersed in bath liquid are constructed of stainless steel or synthetic material. Common applications include controlling the temperature of samples, temperature testing of articles, materials testing, and evaluation, adjustment, and calibration or thermometers and thermal switches.

Aethra CCD Webcam Teardown – From Back When Streaming Was Expensive!

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.

HP T620 Thin Client – PSU Hack And Windows PC Modification

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

The machine itself is powerful enough to put a little work into modding it into a PC, running Linux or Windows off a USB disk or for some models, you can even find a spare SSD slot on the motherboard, unlucky for me, this model does not have that option.

Analog Panel Meter Shunt Calculation and Custom Scale Design

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 Kyoritsu KM-66 1 mA 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.

Chinese 1800 Watt Induction Heater – Horizontal Oven Heat Insulation Test

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
