Re: Adding GPS

NIXIE OXO board.

My finished OXO game. Note the subtle mods: brass domed nuts & washers to complement the golden ink used to highlight the game board. Also the micro USB C socket. Yes, off USB 3.0 I can run it off my laptop! Or even a mobile phone recharging battery! (For enhanced portability!) I used a lacquer ...

Re: Board PCB

I replaced the 5mm power socket with a micro USB C socket for greater power-supply flexibility. (USB v3.0 can supply the current.) Sadly I thought too late to add a "TP4056 Lithium Charger Module with Battery Protection, Micro USB 5V 1A" plus a Li-Ion battery (Part No. PD2280100 from https...

Re: Board PCB

FYI a photo of the pad waveform on the baseboard. Note the voltage is 10x (as I used a x10 probe). Many harmonics.

Re: Piece base case

I note that the NIXIE holders have an internal shoulder onto which the PCB sits so the pins of the NIXIE show. Yet when I try to sit PCB (with a NIXIE with clean pins) in it, the NIXIE will not strike. With the top board & as a test with the base board on top (for a double thickness) the NIXIE s...
