January Update: Finally some closure (Patreon)

Nobody would expect a simple project like this to cause so much trouble. What seemed to be a basic swap of a DIY galvo to an off-the-shelf one turned out to be cursed from the beginning. While having some initial success the +-15V dual power supply is always risky since things go south if you connect it the wrong way. That only happened because I cheaped out on ordering the right supply with the galvo. I used a fat lipo instead and swapped the polarity. That was entertaining on stream as the electrolytics popped and a few components more. What followed were weeks of troubleshooting and trying to fix the driver board again. The result was frustrating as the driver didn't work even after swapping all active components. The positive thing was that we had the chance to play around with the TDA2050 AB-class audio amplifier that's used on the galvo driver and even build a little amp circuit ourselves. Using that amp without the feedback loop wasn't able to drive the galvo precisely, though. That meant I needed to reorder a new galvo with the driver and wait 3 weeks for the arrival. This time I ordered the PSU along it. The new galvo worked well… UNTIL it died. This time it was the motor though. We connected the old one with the new driver and it worked again. Turns out you can destroy the motors driving them with a too high deflection. I only found out destroying a second one and frankensteining a working one from the scraps. Long story short: I made it work after two months of drawbacks. The current state is looking good with a lens for a wider FOV and a pre-amp running Asteroids, a screen share vectorizer and a laser show player. The video is in editing currently and will be my first HDR release. It’s expected to be released in Feb. The lessons learned are that opams are interesting and anything driven beyond 5v.. needs ordering sacrificial units for a project to be finished in a timely manner.

Although, the video isn't ready yet I can only recommend checking out the latest stream for a good conclusion
