Macro lens ring light progress.
Case from an old deceased power supply was good fit.
Modified UPS circuit (previous post) so DC booster can be switched off. Now it uses 0mA when off but can charge when plugged in. So I don't need to worry about deep discharging.
Used switch on the pot of the PWM module for this, both PCBs got some hacks.
Needs a nice knob, some way to close the case and an alien UNC bolt to attach to the camera tripod mount.
