Finishing the last bit of hardware to make the load usable. Temperature monitoring of the power MOSFETs. Also testing the effect of the case cover on MOSFETs temperature.
With the constant current mode working pretty well. I take a stab at the other 3 modes. Constant voltage has a surprise for me. Though if I would have thought about it more, it should have been obvious. And constant resistance is causing the difficulties that I kinda was expecting. Also, I try to get a bit more use from the hardware ADC filters.
Part 28 of the DCL1 electronic load project
Replacing the flexible cable assembly on a Canon imagePrograf iPF9400. The printer was giving intermittent and random, carriage and print head errors. Also the printer would intermittently indicate the carriage cover was open, when it was not.
Machining a block of aluminum into a load cell. Mounting strain gauges to form a wheatstone bridge. This is what the weld tip pressure will be measured with.
Searching for a dsPic MPU for my electronic load project. With the chip shortage, it is definitely slim pickings. But there are still a few deals to be found. And I’m trying one of them: dsPic33CH256MP508.
My last HP Officejet Pro 8100 finally died. Under Linux, I’ve stuck with HP printers for years. But wanting an ink tank printer, and just a printer. I’m going to give the Canon G5020 a try. Come see how it all turned out.
Replacing the USB cable on a Razer Kraken X, model number RZ04-0296 headset. Sometimes the headset would work fine. Other times moving the USB cable would cause the sound to come and go.
Test soldering some PIC16F15354 in the 28 pin, 0.4mm pitch, Quad Flat No-Lead (QFN) package. While these QFN-28 packages were quite a bit harder than the QFN-20 ICs. Success was achieved in the end.
