OIVO IV-P5211B PS5 DualSense charging cradle modification. I didn’t feel comfortable leaving the controllers on the cradle after they were charged. Paranoia on my part, a bit. So I’ll add a couple of Zener diodes to keep the voltage-clamped in case of a boost regulator failure.
Going over the failure of my use of a CPU cooler to test the case temperature of a TO-247 MOSFET. Examining the mistakes made and where to go from here.

Testing the balance of current through the MOSFET power modules for the electronic load. Finding and fixing a careless error in the MOSFET drive circuit.
Part 13 of the DCL1 electronic load project.
Taking apart a Halco 89003 T8 LED lamp. Drawing up a schematic diagram of the internal power supply. And generally seeing how it’s put together. A fun little exploration.
Testing two MOSFET power modules for load sharing. Going for 300 watts total power dissipation. Evaluating the OPA189 for current sense to MOSFET drive.

Working on a Razer model RZ01-0201 wired gaming mouse. Disassembly, where the screws are hidden. Switch replacement. Assembly, reusing the mouse slide feet.
Just taking a look to see if you can spend under $50 and get a usable multimeter. Even if you simply want to replace the joystick module in a game controller, it’s worth having a multimeter by your side.

Using the 175 watt American Beauty soldering iron to put some copper bars together. The bars will create the mounting point for my electronic load’s high current shunt. Part 10 of the DCL1 electronic load project.
Trying to get a hand on just how much case to sink thermal resistance I’m dealing with. Getting a temperature prob on the case to see what is the real case temperature.
