Spot-Weld testing nickel battery tab 0.21 mm thick.
Spot-weld testing some 0.21 mm thick nickel battery tab strip. Weld energy from 50 joules to over 200 joules tested. With a constant tip pressure provided by my motorized weld head project.
In the exploration of my new programming toy. I’m throwing something quite old at it, an ATtiny13A. While old, not obsolete. The ATtiny13A is still in production and available in the 100,000s. And that did surprise me. But can I twiddle the bits in it from the new PICKit 5?
Description:
Starting the quest to build a multi-output DC-DC power supply for the electronic load. Initial test of the MAX17691A from Maxim Integrated. A very small integrated power switch flyback controller IC. And winding some small transformers for the initial testing. Loads of fun for all.
Part 14 of the DCL1 electronic load project.
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.
I’m testing out an FFG rechargeable air blower from Amazon. I'm planning on replacing most of my canned air use with it. If it works as advertised. Does it, watch and see. And I have to tear it apart and see what’s inside.

Using a mini-lathe with a 16 TPI lead screw to make an adapter. I want to attach my Marantz MPM-1000U microphone, with external M22-1 threads. To a Rode SM6 shock mount, with internal M20-1 threads. Plenty of metal chips along the way.

12:43 Assembly & use
Fixing a left door sag on a Samsung French door refrigerator. The door had dropped enough that the mullion was not catching in its groove. Not wanting to take the door off, I make a spacer for the lower left door hinge bushing.

Testing some IXYS linear MOSFETs for use in an electronic DC load. Laying out a test PC board to evaluate precision OP Amp with low cost current sense resistors. Power and heat sink testing. What is going to be required to get to a 600 Watt electronic load.
