Helper board prototype PCBs are here y'all...
mmmmmm...classy...

no no. Just the prototypes to verify the traces. Then we'll send the batch off to an assembly outfit
Yes sir!!

In regards to the top reveal board, personally I have to vote for it being as accurate as possible over the addition of extra features which do sound properly awesome but start to deviate from what I understand the goal of the project and what I personally want out of it (the most prop accurate FX hilt possible). I understand the ultimate accuracy of the board has been compromised already (to what extent if it's not revealing to much?) but feel the next best thing is still fine compared to having something that looks cool but doesnt represent what we know is in the prop.
It is simply amazing the level of detail, effort, thoughtfulness and accommodation that you are both putting into the project and either way the end result will be nothing short of monumentally amazing!

No matter what you choose, Bryan is going to have to endure the process of teaching me how to install the FX as I wait for the static run. I can’t even get past the terminology in some cases. He’s literally going to have to hold my hand in all electronic steps of the process.
alright so I will be revising the helper board to add the switch. No switch is short enough to go onto the top board so we have to have it poke through....
like this:
on the plus side. This makes the switch actually a working set of pads. Not that I know what anyone might use it for (not rated high enough to act as a kill switch for a working FX saber)

I agree, the FX should be the closest approximation to the static possible.
As we (still) are working on this, it’s been a very useful tool to dialogue between the offerings and has helped inform problem solving for both... ultimately, this is the best approximation given the parameters for an appropriately robustly designed FX build... and has helped foresee and problem solve in anticipation for the static. I like to think of it as an active test-bed scenario if the static is the endgame.

I can do my best! Ultimately my assistance will probably be a mirroring of all the pitifully asked questions I’ll have for electronics mastermind Verity Cosplay

Update. I actually think I CAN make this switch work as a kill switch by adding a FET to the helper. Mwahahahahaha
Confirmed. With the addition of a P-channel SOT-23 MOSFET I can make the 300mA switch into a 3A+ switch. So now it can perfectly function as a full kill switch for a FX saber board.
now I just gotta figure out where to find room for the pinout pads haha!

That's awesome! Just sliding the card open to power her up and sliding it closed again, ready to activate the saber will be properly cool
yep. Exactly
Incidentally this same approach may also solve another project I have been working on that requires a smaller kill switch. Using a fet to manage current and use the switch as a gate to the fet will allow much smaller switches to the same affect since the fet is doing the heavy lifting.
current through the switch itself is nearly zero.

Ok so I think with a bit of simplification I can get away with doing all of this on the helper with 9 pinouts.
i poured over most common boards for compatibility and I think i can get away with the following pinouts on the helper:
SW1+: goes to first switch pad on FX board
SW2+: goes to second switch pad on fx board
LED1-: negative lead for first pixel led
Data1: data lead for first pixel led
LED2-: negative lead for second pixel LED
Data2: data lead for second pixel LED
(If Running chained you would leave data2 unconnected and splice a single wire to both LED1- and LED2- to the same led pad on the FX board and cut JP2 on the top of the helper)
BRD+: goes to the + battery supply on the FX board
BATT+ goes to + on the battery
GND: goes to GND pad on the FX board.
this allows all the + signal supply to be shared and simplifies the traces and reduces the pin outs needed.
kill switch operates on the + line instead of the - line of the board power supply which has the benefit of fewer amps going through the helper. Expected maximum amps running through the helper would be around 2A @ 3.7-7.4V. The board technically will be able to handle 4.3A @ 30V so plenty of headroom.
I'll probably need to write up a config / wiring manual to capture all of this but... once I make all the changes I'll have another set of prototypes made up. Hopefully this will be the last iteration for the helper.
Any FX folks who are familiar with wiring let me know if you see any issues with this. I don't foresee any and I have confirmed this setup will work with the most common boards (Proffie, CF, NEC).

Ok. That was a bit tougher than I thought. Kinda like a combination of the games Tetris, Flow as well as a tile puzzle and 4 mazes all in one. The schematic was easy. Getting the traces all to work on the top layer to avoid shorts when bedded? Tough as heck.
but here we go. These soon will be dispatched for prototype. Hopefully the final helper.. with a MOSFET to manage tiny kill switch!!!
just need to get the pinout silk screen layer done and I'll dispatch for prototyping.
