Hello Peter and thank you. Yes, well, that HV module is rated at 30mA max - with all segments on that should draw about 36mA (based on an average of 200uA per segment) which is TOO MUCH - so I allowed space on the board for 2 x NCH8300HV or 1 x NCH6300HV.
So, theoretically - as it stands it is under powered - in practice - all segments are never illuminated at the same time. Things are not getting hot at the moment. There is a jumper to link the two sides of the clock together in terms of the HV supplies which allows the thing to run from a single NCH8200HV - or a single NCH6300HV. Further measurements are needed to be sure. - Richard On Wednesday 10 April 2024 at 07:05:24 UTC+1 Peter Hall wrote: > Stunning as usual..1 x Omnixie to power it all.Amazing👍 > > From🚨Peter Hall😁 insidiousnixies🦘Utube > > On 10 Apr 2024 1:46 pm, Richard Scales <ric...@scalesweb.co.uk> wrote: > > If there was ever an example of over engineering then this must be it! > Here we have 14 PCBs, 180 transistors, 360 resistors and 13 processors all > working together to drive six SP-252 multi segment Panaplex displays using > the Smart Socket circuit that was designed originally for B-7971 tubes. > It's taken quite some time to pull this all together, mostly because of > all the SMD parts and my soldering skills - the resistors are 0603.[image: > SP-252Pic2.jpg][image: SP-252Pic3.jpg][image: SP-252Pic1.jpg] > Regardless, the hardware is done, now working on the software to take > advantage of 12 digits of alpha numeric neon. > Each display sits on its own PCB.
