The stick is finished! A good amount of time was spent sourcing tools and waiting to use the lab or work shop.
The final stick sports:
★ Carbon and glass fibre sandwich construction.
★ Exterior is clear coated carbon fibre with 3 red and gold pin stripes (made in germany!).
★ 6mm clear acryl base plate.
★ 6 rubber feet with screws.
★ Multi-fit mounting plate: Will fit both Seimitsu LS-32-01 and Sanwa JLF-TP-8YT joysticks.
★ Both Sanwa and Seimitsu brand screw-in buttons work.
Stick and buttons:
★ Seimitsu LS-32-01 joystick.
★ Clear Seimitsu ball top.
★ 8 x 30mm clear white Seimitsu buttons on the surface.
★ 1 x 30mm white Seimitsu button on the rear as PS3 home and 360 guide button.
★ 2 x 24mm white Seimitsu buttons on the rear as start/back.
★ Dual PCB Xbox 360 and Chtulhu.
★ Works with Xbox 360 / PC / PS3 / PS2 / PS1 / Gamecube / Wii (via Gamecube ports) / Xbox1
★ RJ-45 mod: Only one cable at a time, different cables for the systems will all fit to the same jack.
★ Quick disconnects for all buttons: Each button can be swapped easily.
★ Inter-PCB connection via SUB-D 25 connector: Each PCB can be removed separately.
I wired the buttons to the PCBs to mirror the MadCatz SF IV sticks:
X Y RB LB
A B RT LT
 /\ R1 L1
X O R2 L2
Y X L
B A R
Start = Start
Select = Z
X Y white LT
A B black RT
Start = Start
Select = Back
Select + X = Left stick click
Select + A = Right stick click
Select + Stick = Left and right analog sticks
So the 360 PCB and the MC Cthulhu board are connected so that RB/LB on the 360 ‘equal’ R1/L1 on the PS3 and RT/LT ‘equal’ R2/L2.
For the PS3 this is also the same layout as the one of the HORI Real Arcade Pros.
The buttons use quick disconnects so the layout can be changed easily. One could also change the lines at the Cthulhu’s screw terminals.
Decided to paint the interior glossy black. The exterior received a first layer of clear coat. On top of it the case received 3 pin stripes in red and gold. When discussing the colors we decided for black, red and gold as their our national colors – made in germany. Pretty international project: Stick + buttons from japan, 360 PCB ordered in the UK, Chtulhu made in the USA.
Preparing the case for the paint job. Initially the interior was not intended to be painted. But it also received a special treatment to increase its roughness to be able to mount parts on the inside. Trying to decide on a color, black is the first thing that springs to mind. But a colored contrast would be nice, too.
The carbide plated hole saws finally arrived and were put to their use. The top right corner served as a guinea pig. Smooth sailing.
Preparations for actually building the case were finished and we could start working with the actual carbon and glass fibres and the resin. Friendly company cs.federleicht let us use their work shop to build the case and the rest of the stick from here.
More parts arrived: Glass fibre in white and black (pictured) and resin (not pictured) for the case.
Got embarassed that they didn’t send a coil but packaged the fabrics into plastic bags. What you want is a surface as smooth as possibe and not a folded hanky *sigh*. That’s what you get for ordering small amounts.
In the SF4 craze it’s apparently becoming harder to find the coveted Sanwa and Seimitsu sticks and buttons. I managed to find a web shop and it’s even in Germany (arcadeshop.de). I Ordered a Seimitsu LS-32-01 stick, 8 clear white Seimitsu PS-14-KN 30mm buttons, 2 solid white Seimitsu PS-14-DN 24mm buttons (for start + back buttons) and 1 white Seimitsu PS-14-GN 30mm button (for PS3 home/ 360 guide). Rounded off with an additional clear Seimitsu ball top.
I chose the buttons because of their color (gotta love the clear Seimitsus). Since I have no experience so far with arcade sticks I relied on web wisdom to choose the stick. Because it was said to have the shorter throw I chose the LS-32-01 over the Sanwa JLF. As I have no preference for a square or octagon gate it doesn’t matter that there is no octagon option for the LS-32-01.
