My controller arrived yesterday. Couldn't wait to try it. Worked great out of the box, so I haven't done the calibration or put the feet on yet. The stick is easy to handle and the buttons respond beautifully. Thanks for putting together a professional looking quality product!
 :cheers:

I got all the vectrex cool kids coming out of the wood work to this thread....  :afro:

@nexusmtz awesome pic, may your scores be higher and the tendons in your hands thank you.

@Vectrexer, I wasn't expecting a full macro focus porn shoot of the CTDE panel. Great Shots! man....

Columbus Day is gonna add an extra 24hrs to the wait for some other folks.  :badmood:



good day.

Chopper, do you mind indicating how you got those nice curly cables?

Best,
Avi

Nice Job.

Think I got lucky with mine, when I stumbled across the vectrex online. It was just before everyone seemed to want one (so before the imo crazy prices)...at that time there was one guy sell his boxed collection (most still have the film on the overlays) and another was selling his vectrex right nearby.

I took that as a sign, not that I needed much convincing. :D

@chopperthedog

I picked up an ebay Vectrex with display issues just before Christmas.  I've long since tracked the problem down, it was a faulty power switch.  After getting the screen going and making some adjustments I then had a great looking Vectrex that I couldn't play because it didn't come with a controller.  So I made a controller, which it turns out is similar to yours, though your case and logo look way better, (I used a plastic tackle box for my case).  I've been having a problem with my control stick though.  I've only got Minestorm to play so far, (a Sean Kelly Multi-cart should be arriving next week), so the only directions I need are Left and Right.  The Right works great.  The Left works good to about the midway point and then starts turning Right.  In trying to figure out what was wrong I found this thread.  After I read that your sticks are 5k ohm I checked mine and found that I have the same.  I had thought I was ordering a 10K, but that's not what I have.  Anyway, I was wondering if you would post or message me with a diagram of the resistor board you made to overcome this problem?  Thanks in advance for any help you give.  I would have messaged you but, where I am new to the forum I can't.

My diagram is the same as the stock vectrex analog circuit, but instead of the "trim pots" used in the original circuit I used a fixed value of resistors. Since the joystick I used has a way of adjusting the X Y centering position. I used 3 resistors in parallel that yielded a value of 1.53KΩ and finalized the trim with on the joystick itself. The sean kelly cart has the Test Rev4 rom so you will be able see what"s off and to tune yours more precisely. If your joystick has no centering abilities I would add maybe 2 - 3kΩ trim pots to your design.



good day.

@chopperthedog

Thanks for replying.  Since making the post, I did some more testing of the joystick with my mulitmeter and found that when I tested it removed from my case and the circuit, both pots showed as being 10K.  While in the circuit both pots are connected in parallel through both the -5v wire and the +5v, which seems to be what gave me the 5K readings.  Once I had that figured out, I checked the original controller circuit in the Vectrex service manual, (which I belatedly read in your reply, great advice for sure), and noticed the two 4.7k resistors and the two 10K variable resistors.  I hadn't had these in my original circuit.  so I added the two 4.7k resistors and in the place of the variable resistors I used two 10k regular resistors.  Left worked great, Right not at all.  I then started thinking those originals were variable for a reason so I took out the 10k resistors and figured I'd start at half of that, the closest resistors I had were more 4.7K, so I put those in, and now in works awesomely.

My joystick does have the adjustments on the potentiometers too, so as you suggested, I will definitely be checking the calibration once I get the multi-cart and have use of the Diagnostics program.  Thanks again, and like all the rest I gotta say that is one great looking controller you made.  It really matches the Vectrex, you'd think it was an OEM pro controller offered GCE back in the day.

Glad you were able to get a handle on it. If you're using a similar style stick in yours, check post #78 of this thread for my little instruction sheet.



good day.

Hello, I'm new here
do you sell those controllers?
I'll be interested if you do!
