Thank you! Wireless charging is a possibility. If I can get this first revision working as intended then im sure there will be plenty of feature creep to come :) On Sat, Oct 3, 2020 at 4:04 PM Dekatron42 wrote: > Looks very nice! > > Will you include wireless charging? > > /Martin > > -- > You

Thank you David! It is indeed a lot of work for one person, as i'm sure you know. This project is heavily inspired by the successful Cathode Corner watch! The software features will be focused heavily around power saving when the display is off, in addition to using the bluetooth radio as the

Hi newxito, Ive been able to get the CJ51-43AL to produce high voltage, but only found that about 5ma @ 170 volts was feasible from a 5 volt input (using the LT-3757afe controller at a swithcing frequency of 100 KHz). Beyond that, the transformer would indeed go into saturation and get very hot.

Kevin, That's quite a project! It has a lot of processing power. I can tell that you've put a lot of thought into the design. I'm curious about the plans for software and features, since you mentioned that you haven't written any of it yet. The big limiting factor of Nixie tubes in a

295/5000 Great project! Have you had any success building a power supply with the CJ5143? I completely failed trying to build a 15x15mm PSU with this transformer. I have got the 170V but only about 4mA and it wasn't really stable. But to be honest, I haven't tried to improve it at all. Kevin
