I now have a deeper appreciation for what u do. I love messing with electronics but u do 'next level stuff'. Wow! Thx for sharing.

[@M-H433]

These sort of videos are fantastic Ian,reminds me of the days Bruce used to do them,keep them coming.

[@jakeclauson9863]

One of the motors stopped working on my v1 firefly 1s back in the day. And boy was I bummed cuz it was my first quad and I loved it. flywoo didnt have the aio in stock at the time to replace it. I noticed one the tiny little mosphets had an imperfection on it. So got the number off phet, ordered some up from digikey, and got a cheap hot air station and microscope from amazon and took a stab at it... shockingly I somehow fixed it! And a month later flywoo got me the replacment aio which in my mind paid for equipment. Plus I'v been able to fix many fcs ever since. Its not a fun task to solder such tiny components but boy is it satisfying when that baord boots and flies off! It was only like $100 for the hot air machine and digital microscope. A very worth while investment for this hobby. At the cost of 1 stack you can almost infinitely repair your boards (if you have a parts board)

[@EnglishTurbines]

Fascinating video using the thermal camera. I like how you tacked the chip back in place too. 🤔😳😮😏😏😀😀🇬🇧

[@TechTimeElectronics]

You have great comprehensive explanations for your boardwork.. Learned a new technique from you today.. I have a bunch of boards that i have transplanted the ic chips to other boards.. Some successful some not. I enjoy the troubleshooting methodology

[@istim]

Very cool! Only recently got into messing with surface mount components and hot air, not sure I’ve quite got the solder skills to work on the pins directly though!

[@EdJakes]

Most excellent and the level of your skill is unsurpassed! Keep up the awesome work!

[@MadRC]

Thanks I am trace that.

[@flyinryanfpv]

Need more of these vids! Cheers Mate🧉

[@claytonallaway853]

Awesome vid!

[@martianmcfly]

great video!

[@RideNFly_FPV]

Great stuff Ian, thanks! Makes me want to get a microscope and give it a go.

[@73FPV]

Love ur channel

[@MadRC]

Thanks.

[@erikvf7]

First! 😛Love these videos! That thermal camera really came in hands! Thanks for sharing Ian, keep posting content like this! 😉

[@bulufish8208]

If u want to learn this is the channel.

[@MCsCreations]

Oh... I thought you've saved this one. That's unfortunate. 😕 Anyway, you tried, Ian! Stay safe there with your family! 🖖😊

[@houssemansolanomontes1329]

sir, you should be a brain surgeon ,with that kind of dexterity ,oh PS, this is not as easy as this man makes it seem ,pure master!!!

[@typxxilps]

Hope to see the PC app soon of what it can provide more even though 90$ is a lot in nowadays world. I paid 220€ for the iniray with the wide lense and I doubt to pay another 100€ incl. vat for such a software. They should offer a bundle at purchase. 4:35 - Ah, now I understand that you have a donor pcb with the same part cause I was wondering first how you could repair that SOC. I like these videos a lot and watch it completely cause I had not thaught that it would work out that way that easy cause these legs or pins are so tiny and working under a microscope makes really tired.

[@SeeFPv-qm6ie]

Can that be done with the tbs nano Rx because two of mine button fell off?

[@Fly_High_FPV]

I noticed the sparkly burning spots around the chip when you first showed it on the orginal board. Thought the internal short was causing certain leads to also short pretty sure it's the same postions lighting after you moved to the 2nd board

[@Fly_High_FPV]

Wicked video...how much wad the microscope? How much for the thermal cam? Have been thinking about getting a cheap usb microscope for repairs

[@dennyrodman2022]

Great repair, thanx! I think this FC still can fly with external micro bec 5v 0.30$ with only 2 wires on usb pins))))

[@prki1024]

What kind of microscope did you use? What magnification level? The quality was very good!

[@kaskalo2]

I dont; understand what happens on 06:07. Is it adding the led or removing it? What's with that bubble following the iron tip?

[@johnstrzyzewski7796]

Great exploration. I've seen corrupt programs turn processors to route an internal MISprogarmed short on. Were you able to purge the hot processor program to blank boot loader mode?

[@MadRC]

Yea it’s a hw short. Iv reflash it from bootloader a few times.

[@testpilotian3188]

Nice, what soldering iron do you use?

[@MadRC]

Axiun T3A, it’s a fantastic iron.

[@sullytrny]

As usual, I forgot what I wanted to ask when your stream is on. But now I remember. Do you know of any products that I can hook up to a UART that will turn ta power source on and off? I want put a small fan on an AUX switch for my VTX. Since I can't disconnect the battery when I land too far from home I want to be able to flip the fan on to use the last of the battery, so it doesn't smoke. And the gps wait

[@user-mh8sq4qt6w]

by any chance you have a Flywoo F745 AIO FC? I recently accentally flicked a blob of solder and it hit 4 of the 0201 resistors. The only way to clean it out was to remove all 4. I need to know the resistor ohms for them, and you are the only person I know on KZbin that has EE background in the FPV community.

[@Robin-Visser]

One thing i noticed is the way you mounted the new chip will never let it sink to the pcb as it should.

[@MadRC]

Tbh I just pinned this one down. It’s got no large pad under so that’s why I did not bother to float it.

[@ChrisQuadFPV]

That is some high-tech surgery. I'm scared 😳

[@kennykobi]

I need to repair a few flight controllers. This is far beyond my skill set. I wonder where I can get them fixed.

[@brandonwoodford579]

I like to use low melt solder to remove stm32 chips(apply with iron, remove with air). wick the unleaded, and apply new leaded solder, then resolder with air.

[@MadRC]

Yea it’s a great way. I just did not have any😂, I really need to top up on consumables.

[@jiatan_fpv]

That's not a great idea unless there's no other way around - any remaining low melt temp solder will mix with the new one and compromise joint strength.

[@brandonwoodford579]

@@jiatan_fpv which is why I say i wick all the unleaded/low melt off, and apply leaded.

[@jas-FPV]

Please include in the videos the temps and flow you use with the hot air 🙏🏻

[@lemonsquareFPV]

Honestly 99% of the time I use 300C with just enough air so it doesn’t accidentally blow small components off the board. 8/10 on my hot air fan. Works well for me. Temperature regulation with distance is my method… also I pre-heat the boards for 20-30 seconds a bit, so I don’t have issues with delamination or thermal cracks on the PCB or more fragile components. I am in no way a professional, but taught myself and do fix 90% of all issues myself, so do with this what you will. Happy flying!

[@phiveone]

BetaFPV, 'nuff said.

[@fj1100mark]

Unusual substance to clean them off Indian pale ale Ian

[@MadRC]

Hjahahahah

[@DavidHanniganJr]

SOC?

[@MadRC]

System on a chip.

[@lasersbee]

8:30... Time to change your Q-tip Ian... That one is starting to grow hair..

[@MadRC]

Haha.

[@dronejunkiefpv9556]

like 113

[@luketurner8728]

lol bin. no one in this hobby throwing anything away spares box it goes

[@imignap]

What? its a microcontroller not an "soc". I cant watch this anymore

[@MadRC]

Ok bye bye.
