  1. I just had the same "bricked" issue occur to me on a Thrustmaster Warthog throttle purchased in 2018. I ordered a replacement mainboard from Thrustmaster for about $70 US including shipping, and it shipped from France. It came pretty quickly. I think I had the order in by Monday, and it was here today (Friday). Here's a picture of the replacement board, which is identical to the failed board except the size of the PCB was slightly smaller. My original has 1808 printed on the silkscreen instead of the 2113 printed on this one. I also highlighted 7 ESD pads that are not populated. I saw on this thread that some people have populated ESD6, but what about ESD 1-5 and ESD 7?
  2. It is a private group at the moment, but you should be able to find it and request to join. This may help: www.facebook.com/groups/openharrier/
  3. I did create an OpenHarrier faocebook group. It's just 2 of us so far. Feel free to find us and I'll accept you. I've been working on a CAD model for the seat and cockpit in FreeCAD. I've gotten pretty far as you can see from this screenshot. Still a long way to go. Hope to start construction in March.
  4. I have lots of experience operating 12V solenoid valves from Arduinos, but I use relays instead of MOSFET. But its basically the same principle. Are you powering both the solenoid and the Arduino from the same power source? If so, the current draw from the solenoid could actually be starving the Arduino and may cause it to reset. I've had problems with this in the past and will often provide a separate, isolated power supply to the solenoid valves so that current draw does not affect the Arduino. I've run as many as 16 rapid fire 5-way pneumatic solenoid valves off a single Arduino, but isolated power supply is a must for that. The current draw from the relays was also a problem, so I use a separate 5V regulator that is fed from the same power source going to the Arduino. The grounds are connected between that separate 5V regulator and the Arduino (necessary in order for the digital IO signal to work with the relay boards). I should point out these relay boards use opto isolators and flyback diodes for the relays. I would have to add those things if I were going to use a raw relay. And for the record, I have controlled a solenoid from an Arduino directly, using a TIP transistor. Here's a demo without solenoids connected:
  5. I'm going to be building a full scale AV-8B Harrier simpit in my basement. I'm starting an "OpenHarrier" group and plan to share all files I create for the greater good of the hobby. For the past couple of months I have spent countless hours building up a CAD model in FreeCAD. I want to use as much free and open source software tools as I can over using paid software. I'm not planning on selling anything, and sharing is caring. Anyway, here's what I've got going so far. The construction geometry is only draft placeholder stuff for right now, as I figure out the size and materials that I'm going to use to recreate the different pieces. I have a long way to go. I hope to start actual wood construction in about 1-2 months and I will certainly be sharing my models by then. For now, here's a taste:
  6. This is really looking great! I can't wait to start building my own throttle (and the whole darn cockpit!). I've spent crazy hours modeling up the cockpit in FreeCAD. I'm getting closer. I haven't yet worked out the construction geometry yet... that is all place holder & draft construction that is work in progress at the moment. I hope to start building maybe next month, March at the latest. I'll be sharing my files on the OpenHarrier FB group & GitHub. Because sharing is caring!
  7. After some more testing, I estimate the "hyper roll" to be more like 1.5 revolutions per second, not 3 to 4 per second. I calculated this by taking the video into a video editor and counting the revolutions over 1 second worth of video. I can't achieve that roll rate without AFC on. The other thing that I have observed is that only my first plane / spawn after loading the mission is able to achieve unlimited sustain roll without blacking out. After I purposely crash the plane and use subsequent planes, I'm unable to achieve sustain rolls without blacking out. If I exit the mission and restart, my first plane will again be exempt from blacking out. Subsequent spawns will black out. So... that could be an ED bug maybe? Will be interesting if someone could try other planes and see if they get that same result. I recorded a video, will post a link to it when it's uploaded to YouTube. First hyper-roll at 2:42 After second spawn, you can see blackout occurs at 10:45
  8. Witnessed something really weird this morning with the Harrier. Jet #1 I was able to get the Harrier to roll at "hyper speeds" like it was an A4 Skyhawk. I was flying a clean jet on the Caucuses map, low-level (100-1000 feet AGL near Kobuleti) with about 6.6 fuel state. Initial configuration was full fuel, no stores. Performed a STO takeoff and flew around low-level pullling no more than 4.5 G's. Did a low pass over Kobuleti runway, and pulled up 5 degrees and started rolling. Noticed that while holding a sustained left or right roll at level attitude or near level attitude, I was able to achieve something like 3-4 full 360 rotations per second continuously without blacking out or redding out. Eventually I held the roll in continuously for more than 30 seconds (I am not sure how long) and the engine quit. Also note that no pitch adjustment was needed to enter or sustain the roll. I may have had AFC on. I thought to myself... this is odd. The Harrier shouldn't be able to roll this fast. I mean this is crazy fast. Something is wrong here. When my plane flamed out and crashed, I tried to recreate it and couldn't get it happen exactly the same way, but could still enter the hyper roll but in a different way that causes you to blackout. Note that I wasn't blacking out at all with Jet #1. Jet #2-5 So I tried recreating the hyper roll from jet #1 and can't get the exact same conditions that allows me to hyper roll without blacking out. I can get it into a hyper roll, but the pilot blacks out after a few seconds. The roll stops when the pilot blacks out. Also, I now have to put in some nose down pitch for the roll - it will not stay level unless I do this (and will crash into terrain if I don't). The only way I can enter the hyper roll is with AFC on and holding slight pitch down on the stick. With AFC off, the hyper roll will NOT ever occur, and if I don't apply a slight pitch down on the stick, no hyper roll will occur. If hyper roll does occur (with AFC on and slight pitch down being held), pilot blacks out after a few rotations. Remember that with Jet #1, no pitch adjustment was needed for the roll, and I think AFC may have been on but I am not sure. I have not since been able to recreate the hyper roll without blackout. Would love for others to try it out. I'll try some more later today and see if I can get a video of it happening.
  9. Here's the latest progress on my CAD model. I figured out how to use the ModelViewer2 to generate planar ortho images to use as references in FreeCAD. I had to rework almost the entire model, but it's starting to get there! I also obtained real seat back and head rest pads from a real AV-8B...
  10. I forget which is the default, but mine is default which means if I move the TDC it will do the TDC action for me. I do have the TDC action bound as well.
  11. I would not say mk82's are useless against MBT's. I usually have decent success with low level drops using snakeyes and airs, but I will drop 2-4 at at a time with low intervals which gives a higher success rate. Of course it is riskier... their gunners can hit you. The key is to come in fast.
  12. By the way, this is looking really awesome. Did you put any metal inside the yellow throttle arm for strength? I'm guessing you did, but can't really tell from the 1 picture.
  13. It won't let me see or download this video.
  14. I have been working on designing a full scale facsimile AV-8B ejection seat, which is the first component of my Harrier cockpit that I plan to build. I've got a long way to go before this design is finished and I can finally start building. What do you think so far? It will be made out of 3/4" and 1/2" wood primarily (most likely MDF, possibly plywood). The seat back will get covered with a thin piece of aluminum (I think) and of course will get a padded seat back in front of that. I was going to make the seat raise and lower like the real thing, but I couldn't find any cost effective solutions for that at this time, but is something that could be added later. When I'm done, I'll be putting the FreeCAD file up on Github to share.
