An odd application of a supercapacitor which works very much like decoupling capacitors in a logic circuit

If the capacitor leads cannot stretch between VCC and ground, how to install the bypass capacitors on a breadboard?
Has anybody ever noticed this problem on a Z80 CPU chip?
Hey Julian,
Have you seen the videos that James Sharman is doing? His build is very interesting too. I reckon his channel disserves more attention then it gets.
Would you mind mentioning him in one of your videos?
Thanks

Sounds like an impedance mismatch at the latch clock input. Maybe in addition to the 10k resistor, you should use a pull-up or pull-down resistor at the input pin. I used to see a lot of this sort of thing back in the day when I was trying to interface TTL to CMOS ICs. Just a thought…
Conformal coating needed on the capacitor PCB to 'weather proof' it.
If im using 4x 2.7v super caps in series so 10.8v max and only charging them to 8.4v do i still need to use protection PCBs?
Your work sounds like mine, fix it as soon as possible, possibly find out what happened after
Good demonstration
Like an Easter egg hunt in Julian’s yard!
make a PCB out of it!
thank you, this made a massive grey area crystal clear for me!

get a remote control connected to a timer. connect it to control a solar rechargeable light.
I don't know what components your computer is using, but I am reminded of a hard-earned bit of wisdom: never gate a latch with the ripple carry output of a 74LS161 (counter). On some parts it's noisy; but not the ones in our prototypes.
Definitely scope out that latch circuit. A logic analyser won't work, because you need to check the actual waveforms, not just the logic levels. I'm wondering if you have problems with "ringing", which a local RC filter will certainly help to cut out. What's the fan-out like in the logic devices in your circuit?
