Hey guys, I have a few questions about LED lighting a Sanwa JLF stick. I’ve read the threads and individual posts around the board, but can’t find some absolute, direct answers. I’m also formatting this help thread in a way that will be useful for others in case they want to do the same thing.
From what I’ve read in the threads and in shop sites, I will require:
- “Hollow bottom” 6mm threading clear balltop (Undetermined, require help on this)
- A basic LED ( http://www.paradisearcadeshop.com/en/joystick-leds/530-white-5-volt-3mm-joystick-led-0855742005307.html )
- A resistor (Undetermined, require help on this)
- LED controller / power source (Remora)
- Hollow Sanwa shaft ( http://www.paradisearcadeshop.com/en/paradise-arcade-custom-parts/422-sanwa-jlf-stainless-steel-hollow-joystick-shaft-0855742004225.html )
*Notes: “threading” denotes the size of the screw holes on the bottom of the ball. Some shafts are a little thicker and may require a 10mm+ threading. But standard JLFs always use 6mm.
STEP 1: I am using the Remora LED Controller by Toodles, of which, has 2 solder spots labelled E1 and E2. Soldering an LED to E1 causes a constant light up whereas soldering an LED to E2 causes a breathing effect. I’m choosing E2. (If you dont have Remora, there is a lot of other LED boards that can do the same thing!)
STEP 2: General circuit of this entire process: Remora’s E2 -> wire -> Resistor -> Cathode leg of LED. Then, Anode Leg of LED -> Wire ->Ground. Can someone confirm this?
STEP 3: The resistor is determined via 3 variables: LED’s forward voltage, power source voltage, and LED current (mA). I need your help here guys. The forward voltage of my LED is 5v. The Remora’s power source voltage is 5v (because it’s power source is coming from the main PCB, which in turn, is using USB @ 5v). Can someone confirm that the power source of my set up is 5v?
The LED current is, I assume, 20 mA. Can someone confirm this?
If that’s all confirmed, that the resistor I would need is a 1 ohm 1/8th watt resistor. Determined using: http://led.linear1.org/1led.wiz
STEP 4: I take a wire, solder one end to E2 and then connect the other end to the resistor. I then follow the path outlined in STEP 2. The LED should function as intended now. (If you don’t know where to wire ground, look at the screw terminals of your dual mod and you can pop the ground wire into there. If you don’t have a dualmod, look at the USB wires and slice open the black one and connect your ground wire into that)
STEP 5: I take apart the stick and install the hollow stick (use slagcoin.com for reference on the stick’s individual pieces). Then reassemble…
STEP 6: I need a balltop that is compatible with the standard JLF 6 mm threading and also has a hollow bottom that the LED can poke through.
I noticed most people use the Seimitsu LB-39, the ones with the little bubbles inside for most LED Joysticks: http://www.paradisearcadeshop.com/en/65-seimitsu-35mm-bubble-balltops
Can someone confirm these indeed do have a “hollow bottom?” Its not clear from the pictures. Secondly, the Sanwa Clears LB-35 line: http://www.paradisearcadeshop.com/en/148-sanwa-lb-35-translucent-balltops
These are perfectly clear, but do not have that hollow bottom. Does anyone know of balltops thats are perfectly clear like the Sanwas without the bubbles, but also possess a hollow bottom? Thanks!
STEP 7: Voila done.
Thanks for anyone who read all this and can provide help. Thankyous.
