    You could indeed adapt the Mustang cluster project for use in a older vehicle that does not have Can-Bus. Of course this would require hardware and software changes. I don't plan to do it. But this effort could be handled by another developer that has a lot of free time.
  14. TPlatt
    Mr.Rc-Cam, could your setup be ran inside a vehicle? Because this is next step on my list. At first I was going to use aftermarket gauges and use the mustang cluster just to house them. But now after I seen what you did, it got me thinking that I might could incorporate your project into getting my cluster to work in a non-canbus vehicle.

    Would someone please tell me which are the RSSI pads on the FR632 Diversity 5.8GHz receivers. Many thanks.

    That's a very "lightweight" LC filter. It looks similar to those sold for FPV drone installations (for video camera and vTx). Don't use it on the 5V to the servos (it isn't designed for the peak servo loads). No promises, but it might help to use it only on the power leg that serves the lower current video devices, such as the monitor and vRx. Interesting find. Especially if you are connecting the wall adapter to the exact same place (and same way) that was connected to the 3S LiPO. I would expect a good performing 3S LiPO to work better than some randomly chosen wall adapter. FWIW, I'

    Thanks Thomas for your reply. No I have not tried different ESC/BEC that has a switcher VReg but i will find and try. Yes i have tried different BEC that has a switcher but same issue.Using Hitec ESC's LDO BEC,it gets much better but i can still see some interference but that i can tolerate. No I have not but i will post my wiring diagram here. Sorry I don't have expertise to pinpoint ground loop issue. I am attaching a picture of my LC filter that i tried. I tried low esr 470uf,680uf,1000uf and even 2700uf on the 12v power rail and 5v servo
  19. Mr.RC-Cam
    Since the Hitec ESC's 5V LDO works well then that seems to confirm your suspicion that the issue is related to the UBEC's 5V switcher. Have you tried a different ESC/BEC that has a switcher VReg? Have you tried a standalone BEC switcher VReg rather than an ESC/BEC combo? Have you investigated the wiring layout for ground loops? Assuming the UBEC can be salvaged, I have some questions about your LC filter. 1. What L and C values did you use? Please post a photo of the LC you built so I can see the physical size of the components. 2. Where did you install the filter? On the 3S

  21. ninja_zx11
    Hi all,Need suggestion from the experts here.My Servocity pan and tilt servos(Hitec HS 785 HB) are putting interference back into the 12v power line and it creates white patterns on my monitor. Interference is visible only when the servos are moving or jittering or if i try to move my tracker forcefully by handI am feeding 12v from a 3S battery to my monitor,pitlab groundstation and to switching mode Ubec which converts 12v to 5 volts for servos.All servo leads are twisted and i have tried using ferrite rings,LC filters, low ESR caps and nothing is working. If i use seperate 12v battery to fee

    Seems possible to me. For example, add a second pot and use a switch to choose between two offset pots (High/Low range). If you don't mind writing some code, use a relay or digital pot. This would allow it to be a menu choice or auto-selected depending on weld current. That might work; Depends on the behavior of your welder's over-temp circuitry. My welder's PWM controller chip (SG3525A) has a hardware shutdown pin. So if your welder uses this chip (or something similar) then you could control weld current (on/off) via this pin. The SG3525A data sheet describes operati
  23. mrtimpovey
    Hi, With regards to the pot adjustment of the offset, do you think it would be possible to make that a switchable range on the front panel? also another thought would be the ability to start and stop the arc from a trigger, could this be put in parallel with the over-temp control input to start/stop the arc for potential TIG use? Mine is very similar inside to your unit but has an LED display for amps, wildly off as it goes from 25 to 250 amps but I will attempt to calibrate it somewhat... A very interesting project! Schematics would certainly be helpful though

    A diaphragm within the wing might work. On the top side having a tube opening on the top of the wing, creating a vacuum on the top side of the diaphragm, and another tube opening on the lower side of the wing. The diaphragm would operate a microswitch when there was insufficient suction from the top surface of the wing.

    The video shows the receiver pinout at the 3:00 minute mark. What it shows matches the photo you posted. The bottom row is somewhat of a mystery (the manual calls it a 5V power output).
  26. Tmo
    I can not seem to find a pinout for the rodeo 150 external Rx connector. The best information I could find so far has me to believe that the top 3 pins (from left to right) are GND, V+ and signal (maybe PPM and SBUS). I don't know what the bottom 3 pins are. Does anyone have a pinout ?

    The A1 voltage should be 2.0V to 2.1V with no RF signal. If you measure 0V then there is definitely something wrong with the AD8318 sensor (or the wiring to it). This voltage represents the measured RF power and should range from approx 0.6V (~0dBm) to 2.0V (~ -65dBm). My first thoughts: The 0V reading could mean that A1 is shorted to ground. Or a power supply issue related to the AD8318 board.

    The Vortex's R/C receiver port expects PPM (CPPM). I believe that some Radiolink Rx's have a "PPM" output, so try to use it if yours is equipped with this. But if your R/C Rx only has S.Bus then the special protocol convertor cable can be used to convert S.Bus to the PPM signal required by the Vortex. FWIW, I don't own a Vortex 285 or Radiolink. So check with the user manuals if you need more thorough advice.

    Hey all, I am new to the race drone hobby and have a r9ds radiolink receiver I'm trying to connect to an Immersion Vortex 285. I have a CPPM to S-bus converter cable on the way... Does this sound accurate? I can't find a video or explanation anywhere. Manual just says you need an Immersion "optional" cable but can't find that anywhere... thank you

    There's a handful of electronic modules that do all the magic. Here's a photo from an early bench test. The brains behind this talking bear is a ESP32 WiFi enabled microcontroller. It's mounted on a piece of Perfboard with two MOSFET modules (for driving the blower and wand motor). A high current relay is used to provide DC power to the 30W audio amplifier. Everything is mounted inside 3D printed enclosures. The pole mounted pushbuttons send an encoded signal to the Bear's 433MHz receiver. The receiver was originally mounted on the ESP32's perfboard, but EMI/RFI

    Let's not forget that the Panda Bear is an important part of the entertainment. It's no secrete that most kids (and adults) like teddy bears. The bear is a commercially made aluminum sign about 18" wide by 24" high. Despite its mostly two-dimensional construction, it can talk and has lips that articulate while speaking. Here's a sample of what the bear can say: The child-like voice originated from a Gund Peek-A-Boo Teddy Bear. It's a stuffed plush toy that was purchased from Amazon, but other retailers sell it too.
