Source for Synthi-style Joysticks |
 |
|
I'm getting ready to start construction on a suitcase modular based around an ASM-2 pcb. I thought a synthi-style joystick controller might be a nice addition since Synthi lust is what gave me this idea in the first place. I've seen lots of commercial and diy synths that use joysticks like this, but I can't seem to track down a source.
I've found a few "industrial" joysticks on mouser, but they don't really look similar to the Synthi joystick and they're a tad too expensive ($150 or more).
Anyone know a good supplier? |

I've gotten dual 150K pot joysticks from Alltronics.com in the past, but they seem to drift in and out of stock. They were less than $5 each if I remember.

Hadn't seen that one yet. Still a bit pricey (Analogue Haven here in the US has it for $70), but probably my best bet so far if I decide I absolutely have to get one. |

you could always look for an old analog joystick on ebay (tandy, etc.) and re-house it.

The one on the Doeper site is the same one that Alltronics carries. I believe its made by Alps. Its simply two pots connected by a linkage. The pots are special because they move thru their whole range over about 90˚ of pot rotation.
I ordered 4 from them on 4/12/07. the part number was 93P005, Price: $3.95 -each.
You might contact them and see if they are getting more.

I get joysticks from the likes of Goodwill, ARC, Salvation Army, etc. They usually have some great old Joystick game controllers, but typically also have the added switch to select auto-centering, or not. And, this switch is separate for each axis. And, they're usually less than $5US. |

Out of curiosity, is the Synthi joystick self-centering or not? _________________ http://www.casia.org/modular/ |

I bought 10 joysticks of the same body type that Photon has the brass paddle in. MY big question, is building a 'centring' device FOR the paddle.
On my dual joystick that I invented (photo of it, below - details on it posted in the Design section of my web page) requires something for both of the joysticks, as the joystick body up in the air, on top of the other one in the base, causes a lot of weight. The wiring from the top joystick also, causes a leaning.
(Having each of the 4 axii switchable on/off can take care of this but .....)
Anyone have any ideas for keeping a shaft centred? |

I've never had the pleasure of playing with one, but I don't think they were self-centering. |

hmm the one i bought a while back (not from this place) was 4-40- maybe they come both ways?

i guess you could use some small light springs configured in an x hooked to the bottom of the carriage-
maybe easier just to get an old self centering joystick off ebay or from a thrift store though.

If you want to get really snazzy, I believe that there is an actual AKS suitcase (completely empty) currently on Vemia, but it's not cheap, beginning at 200 pounds. |

You're probably right. It's not centered in most Synthi A and VCS3 pictures. _________________ http://www.casia.org/modular/ |

Hi,
Try hobby shops catering to R/C modelers. Both online and brick and mortar. Plenty of nice joysticks in R/C gear. the older types will be closer to what the synthi's have. In fact, in the synthi's Ive seen the joystick WAS an R/C joystick of that time.
Hobby lobby is one large R/C supplier that may be able to help. But I'd bet cruising a few of the online R/C modeler forums and posting a request would turn up LOTS of used but useful joysticks due to the fact that old radios are no longer legal under present frequency allocations.
Kind regards, Randal |

Hi Ryk,
Depends upon the style how they are centered. I can't see yours clearly enough to be sure which technique to suggest.
But the most common means is to use two "paddles" shaped like the letters b and d. The holes go over the shaft that provides the pivot for the bail opposite the pot. The uprights of the b and d sit on either side of the bail, and there is a single spring going from one upright to the other.
There is a pin in the joystick housing just above the bail pivot so that as the bail moves the d leg, the b leg is stopped by the pin and the spring between them stretches providing the centering action. And vice versa.
It looks like your joysticks have metal bails? Copper, Brass, or phosphor bronze most likely. These usually didn't come with centering, but you probably could add it inexpensively if you're handy with metal or plastic fabrication. Sheet styrene or brass from a hobby store would be suitable.
The problem with using an "x" spring arrangement is that there is no hysteresis, so centering is weakest near the center and becomes unreliable. It also depends upon all 4 springs being equally stretched when you increase the tension to get past the lack of hysteresis. In short, it doesn't work very well.
Kind regards, Randal (Who used to fly R/C) |

I know that this is kind of an old thread... but since I came across it looking for joystick sources, I thought I'd add what I found.
Digikey stocks 10K and 100K joysticks. More info on this catalog page:
http://dkc3.digikey.com/PDF/T082/P1840.pdf
The only problem is that I can't seem to find matching knobs. If you come up with anything, please let me know.
