Ouch!
Oh, thatās a pitty. They canāt be the same with 110$ difference in cost. Hopefully they are of a more accurate quality.
Damn, Those are much more expensive then expected. I second KĆ„re, they canāt be the same and simply must be better quality. But $272 or $290 is some money for a setā¦
Jim, I think you have to smile harder and ask for a 50% discount 
I found more companies that are selling joysticks but they all ālookā more expensive ā¦
ctielectronics.com/industria ā¦ joysticks/
altheris.com/products/joysti ā¦ st-OEM.htm
etisystems.com/joystickselect.asp
Edit: Found a site that got the same ālookingā ones. Is it an idea to request a quotation?

I have sent out a number of information / price requests overnight. It looks like one place is really big, called Yueqing Omter Electronic & Technology Co., Ltd. Iām hoping they have good prices. Iām also going to submit RFQās for your contacts as well. 
Great! 
Thanks your still on to this!
Kurt,
I did some thinking about the 3-Axis joysticks from ServoCity. Just talked with KĆ„re about this to. Let let me know if Iām wrong with any of my assumptions.
The ServoCity joysticks are not that correct in returning to itās center position. Canāt find the thread, but as we remembered it correctly you said the following about the joysticks. We read the value in a 10 bit range (0 to 1023) the joystick has an center error of 12-16. I guess this error is both ways. This gives an percentage of (32/1024)*100 = 3.125%. ~3%
We can make a thresh-hold of +/-16. The center value is 512. Between 496 and 528 the output will be set to 512 = 0. Ones the value goes above the thresh-hold 529. The output value will not be 529 = 0 but 513 = 1. This way we can still use the (almost) full range of the joystick. The range from the joystick will be 97%
On the mechanical part we also have an error of 3%. The full motion angle of the joystick is 50deg. An error of 3% gives an error angle of 1,5 deg. I donāt think we can āfeelā such an error.
This is offcourse in an ideal situation where no parts in between the stick and the potmeter got any play. Do you also think (feel) some play in there mechanical part of the joystick. Or does it feel pretty solid?
Thanks, Xan
Hi Xan (and Zenta and Jim),
Yes, the problem I have had is the center location. I donāt think it is an issue with the pot, but simply the mechanical construction of the joystick. This is there feels like there is a little slop in the center. What I have found is if I move the joystick aways and release it, it gets back pretty close each timeā¦ But if I make small moves and release it does not always get back properlyā¦ Could be wrong, but that is how it fealtā¦
So with the self centering joysticks, could add in a large dead-band at the center. Would simply need to modify the ReadJoysticks function, that if the value is within 16 of the calibrated mid point, the value is 0, else we map the values on both sides of the mid point. That is for example the line:
diyp.ab[g_aiRawToDIYP[i]] = map(g_awRawSums*, g_awAnalogMins*, g_awAnalogMids*, 0, 128)Would probably go to something like:
diyp.ab[g_aiRawToDIYP[i]] = map(g_awRawSums*, g_awAnalogMins*, g_awAnalogMids* - (16 *8), 0, 127)Note: the *8 is because are sums are of the last 8 samples added upā¦
So yes I think it is doable. Obviously we only want to do this for self centering joysticks. Could even add configuration page to remote, that allows you to choose the dead-band for each of the valuesā¦
I will play with this soon. Have new OLED, but afraid to put it inā¦ Although I could for now probably simply use a couple of short spacers to hold the OLED back from going through the hole in the front plateā¦ Sounds like something to do later this weekend when it is supposed to rainā¦

Hi,
This sounds like a mechanical issue. Is there any way to tighten a spring or something. Iām sure this could be improved mechanically too. Jim, didnāt you also buy one of them? What do you say about this mechanical issue?
I second that. Sounds like the springs are in there āhomeā position to fastā¦
Itās a pitty that an āoff the shelfā product needs improvement right away.
Update!!! I found the real source. I will turn you all onto some, ahem, sample units, and I can easily match the servo city price! I spent the day working on prep work for my garage / workshop. I came in to check email and there was the reply. Good day. No Iāve not held one in my hands yet. Even if the mechanical slop is not fixable these are still a major improvement over PS2. lol
Ah, cool! Thatās great news Jim.
Good news! It will be interesting to see how much home position problems we may have. as I mentioned, I may play around and add a new page to the Arduino code to allow me to choose the deadband width for each of the joystick valuesā¦
Kurt
Thatās great news indeed! Good you found the source! Did the company Yueqing Omter Electronic & Technology Co., Ltd. had them available?
Looking forward to the āsampleā units
Yes the company is Omter. Iām arranging an order now! Weehoo!
I also found a source for these nice crimper tools too! Been looking for them for years!
I did also search for a while for crimp tool like that. But all I found was pretty expensive so it ended with a more simple version. But it worked ok though. It look like this:

Its a Texons product.
The crimp tool you found looks more professional though. Nice find!
I have one of these: pololu.com/catalog/product/1928
Works OK, but, I found that with the servo wires, I double crimp. That is, first I use the 2nd slot to crimp it and then move it to the outside one and do it againā¦

Here is the PDF from the joystick mfg.
joystick.pdf (478 KB)
Do you guys want to tell me what you think would be the best to get?
The faceplate comes in 4 styles. Do you think I should stick with the āBā version?
I donāt see the need to carry the 2 axis with the big knob. Does not scream robot to meā¦
I will go with 10k and 0 to 10k ohm throw, for 0-5vdc out. Does anyone see the need to go with 5k ohm. The 10k pots will draw half the current, but itās not a lot either way.
