iRangeX - how not to make a controller
Вставка
- Опубліковано 21 бер 2018
- A dissection and analysis of the iRangeX controller. We managed to identify and fix three big design issues, and on top of that, we tested the range and latency. Overall, poor product.

once again, these videos are amaszing. i am blown away
The name of this chanel really delivers to its videos. I dont know why this chanel has less than 1k subs.
“You might learn something today“ that Joshua Bardwell quote is just 👍... ;)
Damn you guys got some great electrical engineering skills. Great job!
Great job on debugging. Wish the manufactures were as skilled.
We should totally offer this kind of investigation as a service to RC parts manufacturers. At our regular consultancy rates of course :D
ALL your vids are of great quality. I know one day when you would have a ton of SUBS!
Great review! you deserve more subs.
Woaw thats really amazing man :)
It would be awesome if you could make a video about your range tester and explain how it works
Anyway keep up the good work your channel is sooo underrated ^^
Ditto to everything you wrote.
Great stuff dronelab!
Keep it up. Love the content.
wow you guys are amazing!
Great video! thanks
You just saved me a hundred dollars. Thank you.
Great review! I'm really curious what they've done to the v2. I have the original which is more like a pre-v1. It doesn't have button labels, the potentiometers are different and the lanyard hook is different. I do like the gimbal stick ends. They're now on my Jumper T8SG.
Whiffles does the jumper t8sg have any of these issues?
Not at all. Jumper makes a much better quality product. I love the T8SG Plus.
Thank you. Spot on.
Does the jumper t8sg have these same problems?
We don't have one on hand, so can't test that. Looking quickly at other reviews, it doesn't seem like it has these exact issues, but don't take my word for it.
The system has been updated, I have no issues. Painless360 did a review update of it.
Can you put a link to the parts that you use to fix it?
All parts are very much off the shelf. For the most important fix - the gimbals, you can use any tape. The switching-off glitch, use a 20k 0603 resistor. You can solder it on top of the current one, which is much easier than removing the one that is there (removing SMD resistors is best done with two soldering irons, one in each hand). For the speaker, use any buzzer that does *not* have a built-in tone generator. Can be piezo, or electromagnetic, it does not matter at all. Hope this helped!
I have a radio of that one more this one with problem to lose signal very easy it wants to be able to be that 20 meters already it was lost the signal
Make sure your transmit power is set to 100mW (and not uW!) . You can see it in the top-right corner on the main status screen (for example, at 0:30 I have it at 150mW). If that doesn't help, you might need to open it, and check if the antenna is properly connected. At 2:48 you can see the antenna connection at the very top of the board, with the gold connector and the grey antenna cable - check if yours looks the same. The issue could also be in the receiver, so you might want to check its antenna as well. Good luck!
@@dronelab1280 yes I adjusted to 150mw I checked the antenna everything ok, even more so it still keeps losing signal very close. how would you use an extraneous module?
I got one of these when they were still in pre-order. After getting it and finding the issues with the gimbals I tried to get a refund. But banggood offered to just send me new potentiometers. I said no thanks. And I again asked for a refund as I had already fixed the issue. They gave me a 50% refund. I'm actually pretty satisfied with the radio for only about $40. But at $85 original price it not even close to being worth it. I also did a 5dbi external antenna mod and I get much better range. And lastly I upgraded the firmware to a newer version for this radio. In the end, it works. But it's definitely not my go-to radio. I would not recommend it to someone not experienced with making modifications to electronics.
Thanks for suffering so we don't have to :)
Hello and firstly very good video but i dont undertand the first issue my irange always do a "bip" when i turn It on
Can you explain me a little bit
My english level are horrible
The beeper does makes sounds, but, at least on our unit, the sounds are very “unpleasant”. Instead of melodies it makes a weird sound. They used a wrong part in production - instead of a normal speaker they used a buzzer, that can only produce one tone. But they try to play melodies on that buzzer, so it results in weird sounds.
It’s not an important issue at all, but just shows that they didn’t put high attention to detail. Especially since the part they used is more expensive than the one they should have used.
dronelab okey but i dont understand how do you produce that melodie because me buzzer only do a single "bep" when i turn It on
Oh right! You can program any melody if you connect the irangex to a computer and edit the configuration files. I can show you how when I’m back from a business trip ;)
Excelent, thanks you very much
dronelab and it's posible to remove the buzzer and conect the speaker
It works?
Hey, didn't know you guys live in Sweden! Var hälsad.
What gave us away? Other than the amount of snow ofc :]
dronelab "Farthinder" ;)
Swap out the module from an IR4X to solve the range issues
KTH vad är det jag ser?
Precis!
Well done they should hire you LMFAO :)
OMG so much work for a video about a terrible product.
Very entertaining though.
Amazing!!! Great eye opening video. All Chinese have been doing is copying , implementing and making money on the back of the open source community without contributing back. Starting with the arduino project and going further to opentx, deviation and so on.... that's all they can do, copy... and very little innovation... unfortunately,
I wouldn't go as far as to say it's all bad. The cheap clones of arduinos, sensors and other modules made the electronics hobby much more accessible, especially to students and kids on a budget. As long as those devices are functional, I'd call that a good thing. There are some companies in China contributing perfectly well with their own PCB designs and open source software, like DFRobot for example. This iRangeX controller is a particularly bad apple though, definitely worth shunning.
Stolen firmware ? you kidding me? I thought if Deviationtx is open source project - it can not be stolen. just take the code and apply it to whatever you want.
My thought exactly, now admittedly you have to follow the guidelines set by the dev's but it's usually "make a screen that shows the dev's message/links etc..." and if you modify the code share the code. github.com/DeviationTX/deviation/blob/master/LICENSE.TXT
You aren't "stealing" from open source projects. Its called "using". The only requirement is to release modifications as GPLv3 and attribution.
Yeah, "stealing" might have been a bit harsh, but they didn't attribute, nor did they release the modifications anywhere. The people behind the deviation firmware had to reverse-engineer the hardware changes in this controller to be able to make builds for it. I guess "misappropriated" would be a more accurate word for what irangeX did.
open source firmware can't be stolen
