What are daisy chains and how do you make them?
I am new to stick building and am in the process of making one. I have all the parts currently including: blank case, sanwa joystick, sanwa 30/24mm buttons, and ps3 Cthulhu pcb. I want to get all the info I need before I start and do everything correctly rather than jumping in on it and winging it.
Someone told me of a concept of daisy chains but I have no idea what that is or where to start. Any help is appreciated.
Daisy-chaining your grounds just means that you have a single continuous ground wire for your buttons, instead of separate wires running from each button.
It saves you a bit of wire, and looks neater.
However, you can only do this with common-ground boards (e.g. Cthulhu).
Please review Slagcoin: Joystick Controller - PCB and Wiring
Thanks for the explanation.
Do you have any suggestions as to what not do when installing any of the components or common mistakes to avoid?
Make sure that you give yourself enough slack that all of the terminals can reach the buttons. And crimp everything nice and tight.
Ah exactly what I was looking for, thanks.
This is probably a dumb question but where can I find the roll of wire you have there?
I get my wire from Fry’s Electronics. 22 -26 Gauge stranded wire will work. They got them in 5 colors there. Avoid solid core wire. The problem is that the Sunnyvale Fry’s is out of the 26 gauge black, so better check the Palo Alto, Fremont or San Jose Fry’s if the Sunnyvale doesn’t have the colors you want.
I like 26 gauge because they fit in small through holes, but most people prefer 24 gauge.
Also there is another electronic supply off of Lawrence expressway. HSC electronic.

Nice. I live really close to Sunnyvale frys so I’m really glad this was mentioned. Thank you sir
Would 20 gauge work as well? This is all I could find
So all the buttons work except for R2. Could this be because of the daisy chain? Would I have to redo the daisy chain over again?
o_O
If you crimped your terminals correctly, any ground on the daisy-chain should work with any button.
Try switching wires around to ascertain whether the problem lies with R2 itself, or a wire.
since all other buttons work, its probably the R2 wire or the soldering at the PCB thats faulty. do as kikimaru suggested, switch the ground from the working buttons to be sure 100% since u know for sure those other grounds work,
I think I’ll just redo all the wiring. I used 26 gauge wire and that stuff is so frustrating to strip. Plus I have a cheap wire stripper.
I took my time at first but I had to try and strip each wire at least 3 times because I’d end up getting a piece of the wire with the insulation. So I started losing my patience and just half arsed it the rest of the way
so i tested the R2 and it’s not the pcb thats the problem. i plug in other wires to R2 and they work. could it be that the actual button is faulty?
yeah with 26 gauge wire you need an automatic stripper like in my photobucket. I was at Sunnyvale Fry’s this morning, and they are out of a lot of different wire.
Do you know of any stores in Sunnyvale or anywhere in the bay area that sell pcb mounting feet?
I just realized I have a very dirty mind XD
Yeah I’d love an automatic stripper. My cheap stripper isn’t getting the job done
thats a possibility. test this: use the actual quick disconnect ends of the R2 wire and the specific suspected ground wire and touch them together. if it works, then u are right about ur suspicions with the faulty button. that, or try connecting the said R2 and ground wire onto another button to check.
Thanks I actually just redid the daisy chain with new 22 gauge wire that I bought and they all work now. Thanks for all the help
