This weekend is Sony CRT weekend. The headliner is the new 120V DC/DC converter, tomorrow, but let’s start with this VGA to 40 pin IDC connector board. It replaces the contraption on the left. The new board has a nice extra: an I2C EEPROM!

Junk merry go round! I bought this front panel on eBay as a donor for the Horizontal knob, just sold it on eBay for the Vertical one. tomverbeure.github.io/2024/04/17/T...

Everyone should be aware of the line that has been crossed in the Trump trans military EO. No longer is this about "evidence," "science" or "protecting kids." Now, explicitly, black and white, it's about trans people being "liars," "dishonorable," "false." It's a big step towards very bad things.

More cleaning up, more stuff to give away: the #Hackaday Supercon 7 (2023) badge. It uses a Raspberry Pico to emulate an analog vector scope. Let me know if you want it and I’ll send it to you.

I met a retired power supply design engineer. He was very interested in building the 120V DC power supply for my old Sony logic analyzer CRT project from a few year ago. This is the first prototype. It looks chaotic but it works great.

If anyone wants last year’s #Hackaday Supercon 8 badge, let me know. I never really used mine and I know it will just languish for years in a box with all the other badges… Even if you don’t use the add-ons, it comes with a Raspberry Pico W. Free to a good home!

LTspice (or any Spice really) quirk: 1000M is NOT 1000 mega by 1000 milli. If you need 1000 mega, you need to write 1000Meg. !@#$!@#%

Mechanical design preparation of LED cube nr 3: modelling the backside of the LED panel to make sure that the frame does interfere with the components. I’m giving FreeCAD another chance. The most important is to get the clearance between a boundary and closest component right.
