Hi Sajarov,
there still is.
But I just did an A2A refueling
in the F18 and never noticed
anything.
On the contrary! The "poti"
is much more responsive and for
the first time I was able to
stay connected for the full refill.
Because of your question I
went to the CH Manager and saw
that there is a change in output
by one digit in some places,
and I dont believe its the "poti".

Cheers

I had a chat with Merkin via PM. I believe this may be due to noise on the power supply or digital noise of the CH Throttle Mainboard. With a bench power supply I get no jitter whatsoever and in a Cougar the signal is also very clean. This seems to be a CH specific problem and I will have a look at it. CH sadly does use last century electronics in their devices, so my planned upgrade mainboard will probably solve this once and for all as well. Ill test if different type of decoupling Cs have any influence and if I can improve on grounding somehow.

However Merkin said it is not noticible ingame at all, so it seems to be only minor noise. Anyway I will investigate this, Id like to get things perfect!

You can also try some filtering. A simple 2x filter is in most cases more than enough to get rid of minor 1 Bit jitter, while it cant help with a badly spiking pot. This guy here wrote a nice script: https://www.reddit.com/r/hoggit/comm...cts_with_this/

Just uploaded the CH index finger slew sensor housing + hat to Shapeways. It is designed for an ALPS RKJXV1224. I also ordered all my latest models for a testprint. Now I just need to get the PCBs sorted.

Firstly I think I found the problem with the CH pots. The decoupling caps I am using are of the wrong value, I ordered 100nF caps but got 10nF. So as decoupling caps these are pretty much useless and I might have been using none at all... Decoupling caps are basically for smoothing out the power supply and reducing noise. Before I realized this, I had already redesigned the PCB and possibly improved grounding a bit, so newer sensors will have a rev 1.1 PCB.

Secondly, I received the Shapeways shipment today, but I have to say tolerances this time were abysmal.. I contacted Shapeways, lets see how it turns out. Anyway, here are a few new toys.

CH sensors for Combatstick, Fighterstick, Pro Pedals and Yoke:




Saitek sensors for Pro Flight Pedals. However, these need to be redesigned because currently they are just way too hard to assemble and some dimensions are not quite right yet. Please ignore all the dirt, once the sensors are ready I will clean them thoroughly.




Next, CH hats and slew. I absolutely love the feel of the CMS and DMS hats and the slew sensor. The slew sensor case and hatswitch case need a bit of work as it is a pretty loose fit currently, but it might as well be that Shapeways botched the dimensions this time.. The new PCB for Combatstick to Fighterstick conversion is getting along good, but I have only so much spare time per day.







Finally, I can now offer Allegro 1324 based hall sensors for the Cougar Throttle (for those that do not want to convert their Cougar Throttle to USB standalone and use my digital 14 Bit sensor). I tested this setup today and it works as expected, calibration is easy too.

Price will probably be 15€ with cable as PnP, but I cant ship before next week.

New hall effect sensor kit for the Cougar Throttle without the USB standalone adapter:

Quote:
I can now also offer a Hall effect sensor kit for the Throttle. It consists af an Allegro 1324 hall sensor + cable and a 3D printed casing + N52 magnet. It is plug and play for the Throttle unit without my USB standalone adapter and similiar to older hall sensor kits for the Cougar.


Price is 18€ + 6€ international shipping

Just yesterday I found a crap ton of docs on the real dimension on F-16 parts. Just updated the CH Slew Sensor, it is now completely to spec of the real deal (although I was very close).

Also good news on the STM32 front. I played around with several HID enabled firmwares of these little 32 Bit ARM MCUs and I may have found a way to make them TARGET compatible. That would make it possible to install a replacement mainboard for all older joysticks with 1000Hz updaterate (standard Cougar has 100Hz eg), 14 Bit axis resolution, 4021 shift reg support and TARGET compatability (maybe even running on FreeRTOS instead of last decade Arduino loops). That would be like the holy grail of flight sim gear..

I finished the CH Fighterstick mod PCB. This PCB will convert a CH Combatstick into a Fighterstick & more. The bottom header pins will connect directly to a shift register PCB, which I will do next. It is also compatible with a superb quality Knitter MPS103F as pickle button, at least the cutout is there.

Anybody interested in F-16 combat rudder pedals for eg... MFG Crosswinds?

First: Thank you! I replaced the Z axis pot for a CH pro throttle USB with yours which arrived yesterday. The jitters are gone, installation was easy (no solder despite the good advice), and I can apply flame and pliers to the original pot. I will make it match the many S-3's that it plowed me into.

My throttle's analog thumb-stick is also very twitchy. Maybe your product can help my USB throttle:
  • Can your product replace the CH thumb-stick pot as well as its plastic bits in my USB throttle?
  • Is your slew stick analog like the original thumb-stick or '4-position-clicky' like the index finger position hat?
  • If I also replaced the index finger hat with one of your slew sticks, would that control change seamlessly to an analog axis (like the original thumbstick instead of '4-position-clicky')?
  • How is installation/removal of both the CH throttle's thumb-stick and the index position? Is it loose plastic fittings like the Z-axis pot? Is the wiring also done with those lovely little crimp connectors?

Pictures might clarify it a lot... I'm enjoying my throttle too much right now to figure out how to get to those bits myself. Thanks!

Hey kojdog,
Awesome to hear everything is working well for you! My slew sensor uses the same type of analog microstick as are used in Playstation 4 or Xbox controllers. Theoretically it can replace the thumbstick directly and interface with the CH mainboard, but you would have to cut out a part of the PCB. The CH hatswitches and microstick on the thumb panel sit on top of a PCB and the distance between the black plastic cover and the PCB is simply too small for a PS4 Microstick. If you cut the PCB and solder the cables derectly to the Microstick it is possible. On the indexfinger position it is a simple swap, but you still have to connect it to the CH mainboard somehow. You could swap the original Microstick for a four way (from the index position) and insert the slew sensor in the index position. Again, not sure if its worth the hassle.
I will do a new 12 Bit PCB for the CH Throttle eventually which will make it easy. Just right now I have higher priorities.




Btw, big thanks to the community! I sold all the sensors I made and now have recouped my initial investments and had enough money over for a Creality Ender 3. The printer arrived today and I hope I can start making 3D prints in good quality soon. This is going to be put on a first big test for prototypes of my MFG Crosswind combat pedals. These are as close as I can get to a F-16C Block 50 pedal without 3D scanning. A few details need to be reworked, but they are almost done and will soon go out to beta testers!
