Older Technology / Thermostat upgrade

« Last post by SeanB on November 08, 2020, 01:30:28 PM »

Replaced this slightly elderly thermoswitch, using a more modern digital one. Original is a 96x96mm unit, new one is a more modern 48x48mm unit, so a blanking plate was needed to fill the hole.

Original one from 1976, just slightly out of calibration, as turning the dial (broken in trying to get it open, though it was more or less so already) as the pointer was pointing at 120C, while the heater element was at 160C, a small 40C plus error. Strangely enough I can actually buy them as new stock off Aliexpress, and there apparently is a US company that refurbishes the old ones, there must be enough demand to still keep these running, but at a price. New is a bog standard BTC controller, a lot more capable, PID, multiple input types and 2 outputs in the package, as opposed to this old one with nothing other than some hysteresis, and a meter to show error in the setpoint and input. Had to glue that back, just to show, as the little bit of tape fall off years ago it would seem, and the meter movement was floating inside the case. No IC's in sight, just analogue discrete circuits and a real wound iron transformer to provide power for the electronics.

Measuring Noise - HP 3400A True RMS Voltmeter - Part 2

https://www.youtube.com/watch?v=1Pdcoi8-K60

------------------------------ Click "Show more" -------------------------------------------
A look at the challenges of measuring power supply noise and ripple on oscilloscopes and multimeters. A look at the HP 3400A True RMS Voltmeter
which has enough bandwidth, impedance matching and crest factor to do these measurements to less than 1 mV or up to 300 V.

General Discussion / Re: Super Thin Wire

« Last post by SeanB on October 14, 2020, 07:56:04 AM »

Yes, you probably will want 28AWG wire, as that looks a lot like this, though you could also order enamelled copper wire instead, same gauge, and have it even thinner, though it will be single strand.

Otherwise do you have any of those cheap USB cords around that you can simply cut and strip the outer sleeve off, giving you 4 colours of this wire for nearly free.

Hi All, My wife wants me to make another lighted Christmas card this year. When I ordered the tiny LED's I didn't realize the leads were too short.Can I order this wire on Amazon?Not sure what its called.

Solar Panel Test Bed - Part 3

https://www.youtube.com/watch?v=HZJ_cnqnWL4

In this 3 part series I discuss the following:
* The process and this to take into account to build my solar panel tester
* Why do thin film / amorphous solar panels potentially perform better under low light and shading than other solar panel technologies.
* The build and calibration of my solar panel test bed.
