DIY RC LED Install - Tamiya Audi Quattro A2 Body Detailing Pt 3
Vložit
- čas přidán 6. 09. 2024
- Welcome to Part 3 of my Tamiya Audi Quattro A2 Body Set Build and detailing guide. Today I am testing my setup of 3 volt LEDs before finally installing them into the body. I want to run the LEDs straight off the main RC battery, with 2 headlights, six spotlights and 2 rear lights. First I have to work out how to wire them up safely, so I make a test rig - let there be light!
The component I used were as follows:
3mm and 5mm 3 volt LEDs, forward voltage = 3v and forward current = 20mA, Light Beam Angle = 30 Degrees
220 Ohm 0.25 Watt metal film resistors
The Tamiya battery plug, connector and switch were stolen from an old Tamiya MSC (Mechanical Speed Controller)
Thanks for watching! :))
BROSKI now she's gonna be looking fancy! Lights r gonna set it off!
Cheers, BROSKI!!!! Fancy sounds good to me brother - let there be light! :)

Hello mate. Sorry for the delay in commenting. I wanted to watch this all again when I was not in such a hurry as I was on Saturday night. I still got a bit lost in the sums. My brain has turned into jelly since I've been doing the driving job! I was thinking that 3 LEDs in series would be about right without a resistor. I haven't done the sums mind you! Anyway your setup seems to work well and doesn't overload anything. Great to save a load of money by doing a bit of work with the soldering iron. Anyway I did find it all very interesting and it's great to learn some stuff or re-remember it. I can see how you must be a great teacher at the school. This shell is going to look great with all those lights blazing. Anyway hope you had a good weekend. I had a great evening on Sat. Did find some electro pop to dance to in the end. Lasted till 3am which ain't bad at my age. Laters matey 😀
Hello Pete. No worries on the "delay???" Glad you always bother to take the time my friend! Hmmm, 3 LEDs in series doesn't work on 7.2v matey. I tried it, they barely glow. That's because the forward voltage needs to be 2.8v minimum to get them to work properly. 3 in series = 3x2.8 = 8.4v. So you'd need 8.4v + to light them up. Just 2 in series means 3.6v across each LED, way too much and the LEDs glow like beacons, but get very hot very quickly, hence the resistor to reduce the voltage - does this make sense?
I got the head and tail lights done yesterday and it looks great, just the spots to finish. Glad you had a good night - 3am? You nutter!!! See ya later young man! :-)
Now that was a really great explanation of how to DIY
Ohms law :) takes me right back to the school bench :)
I'm really looking forward to see how it looks now
Thanks very much, Are! Yeah, I felt like I was back at school, too! The LED install is going well, the headlights and tail lights are fitted and working, just the spots to do! All the best my friend. :-)
Thumbs up time to sit back and enjoy the show
Cheers Kirkster! :-)
Thanks Mark, For me being a Brummie looking for DIY lights this was both clear and simple. I have all the bits on order to make a few lights. Just built a crawler from bits and my plan is to have some lights. looks like I have some working out to do as I have both 2s and 3s batteries I run it on.
Fantastic! Great to hear from a fellow Brummie! Ah, so if you do swap from 2S to 3S it might be easier to wire up to a spare port on your receiver, if it has one. They are usually 5v so just 2 LEDs in series with no resistor might work OK. You'd need to wire each set of 2 LEDs in parallel with each other where they plug into the receiver, if that makes sense?!?!?! All the best, mate!
@@MarkBryanRC haha no sense at all but I will try and work it out. Yes I have a 3 channel so have a spare port. I will watch your vid again.
@@jord001 Good luck with it mate! :)
Fantastic work my friend! Pretty nice for custom lights. I always buy LED's with resistors already soldered/installed. So I just need to solder the LED's together and can use them with my 2S and 3S Lipos. Have a fantastic weekend my friend! 👍
Me too. I can't understand anything about resistors and ohms 🥴🥴🥴
Thanks Charlie! Yeah, I could have done it that way, but I enjoy a bit of tinkering with the soldering iron, so I thought I'd have a go! It was pretty easy really! Thanks for the awesome support, and a s always a great weekend to you too! :)
Good explanation and example Mark! My knowledge in electricity is approaching - infinite 😊
Thank very much! Well, my knowledge is very old, like me - so it was good to do a test rig to prove my thinking was correct! Thanks for watching my friend! :)
It's fun to watch Tamiya Audi working on it, and I'm looking forward to it.👍👍👍
Hello Kyouwa san! Thank you for the kind message. I hope you will see the Audi with all the lights working in the next video. Thanks for watching my friend! :-)
An update after my own heart me Mate!! 😁👍👍
Custom work enthralls me. Wiring can get fiddly, but is also satisfying!
My 46 Dodge Power Wagon Body is HERE!! I'm going to try to get as much of the custom work on Video as I possibly can.
Thanks for the inspiration my dear friend! 👌🍻🍺 Cheers!!
Carmine ✈🚂🚙
BTW, I wish we lived closer...
I've got 12 watt, 10mm LEDs, that would give your Rally Spot Lights SCREAM!!
I'm fitting 2 of them in my 46 Dodge Power Wagon Body, which is HERE!!!
.... Have I mentioned that? 😜😂
Cheers, Carmine! Yeah, I got a big feeling of satisfaction when my test rig worked exactly as planned!
Yes my dear friend, I do believe you have mentioned the Dodge body! :P
Are you sure you got the correct figure there for the LEDs? 12 Watts? Mine are 150mW !!!
12 Watts of LED would easily light up a large room! Could it be 1.2W?
Anyway, it's always great to read ya, mate! :)
You're correct... I read the wattage for the package of 4. They're 3w each, and hellaciously bright!! 😳
WOW mate! Even 3w is super-bright, it's gonna light up the back yard! :)
Yessir... Arizona is DARK at night! These will come in handy. I bought them over 10 years ago, and forgot about them. 😜
Very interesting Mark good work I cheat lol I just buy the cheep white and red lights from Ebay that plug into a 5v reciever port and solder the together and plug them straight into channel 3 or the binding port they don't flash or anything but they do light up nice lol
Cheers Brent! Yeah, if only I had a spare port on my ancient AM radios I could do the same! Makes a lot of sense! But then maybe others can copy my method and create some light rigs for a few cents, all the 10 LEDS and resistors for the Audi add up to less than $2!!!! All the best my friend! :))
Fantastic Calculations Mark On the LEDs 😱 your not related to Thomas Edison are you lol 👍💡👍 Absolutely outstanding info video , Sorry for the Time it took to watch it My Mate. Carnt wait to see the installation Video, 👍hope you have a fantastic weekend 👍🥰👍
Hi Tony! Forgive me for the late reply, I don't know how I missed this one! Great comment bruv, haha, no I'm not related but thanks for the compliment, you make me laugh mate! All the best and look after yourself my friend! :-)
Congratulations on having made such a clearly explained video. You took us through the maths nice and gently - and now I´m all the keener to see the LEDs and wiring go in.
There´s something very satisfying about using a little lateral thinking to save yourself being overcharged for any product.
Hi Del - thanks for the great comment dude. Thanks for reassuring me that it was easy to follow, it's tricky to get all the details across and not go on too long and bore people, or to blind them with too much theory. Yeah, I hate being ripped off, especially when these LEDs are very simple circuits made with extremely cheap components! Haha, I bought a string of 20 LEDs running off a 2 AA battery box from Poundland! Now that's how cheap these RC LED kits should be! :)
@@MarkBryanRC I think you got the balance just right - you didn´t assume that everyone remembers their algebra (I remembered that V=I R but couldn´t remember how to twiddle the equation around to get the value we wanted) but avoided patronising your audience. You´re right - it´s not easy.
As for the ripoff merchants lurking barracuda-like in the murkier recesses of eBay and Amazon, one way we can fight back is by posting videos which show how straightforward it can be to do stuff for yourself : )
Thanks again mate! Yeah, remember, when you move a value that is "multiplied" to the other side of the equals sign, it becomes a "divide" and vice versa, just as a "+" becomes a "-".
Great point about the sharks ripping us off, and the only way we can fight back!
The LED install is going well, the headlights and tail lights are fitted and working, just the spots to do! All the best my friend. :-)
@@MarkBryanRC And to you, Mark : )
Looking good Mark. Great explanation my friend.. It's great to be able to do your own lights like that brother.. Well done.. :P
Hi Nick! Thanks for the great comment brother! Always appreciated. Let's hope I can get the real thing into the body without melting the Lexan with my soldering iron! :P
😁👍 Good info for the rc guy's looking to do some custom LED lighting.
Many thanks, Steve! Yeah, it's not too difficult if you follow the rules - good old Ohms Law! :))
This is helpful! I want to do it by all means.
Thank you very much, and sorry for the late reply! The LEDs are easy to wire up if you have a good soldering iron! :)
Brilliant going mark this was Very well explained you made it easy for someone like myself to follow if I ever attempted to make a light kit proper nice going mark big thumbs up all the way 👍👍👍👍👍
Thanks so much, Kirk! Glad you could follow along, it's not that difficult if you follow the rules and stay on the safe side - always better to have a resistor thats too big than too small! And I like playing with wires, switches and a soldering iron anyway! All the best matey! :))
You sir Mark are brave, cant wait to see them in 👍🏻👍🏻
Hehe - thanks Matt! I have no excuse really, I had to do it myself - I was trained as an electronics engineer after leaving school! It was fun to do though, just need to make the final circuit and get it installed - cheers dude! :-)
You lost me at V=I/R hahaha 😀😀😀 Big respect and thumbs up for having the intelligence to do it this way Mark. I mean that in a serious way and really admire you. It's something that I couldn't do when I first looked into making my own lighting systems. I'm the same as Charlie. I always make my own looms by using pre wired leds and solder the wires together. Then l solder them to a servo plug which fits straight into the receiver. The Tamiya light unit kit is a big rip off. The only ones I have were already in the RC's that I've bought. I'd never buy a new one. Axial sell the same kind of unit and leds. Way too expensive for what they are. Look forward to part four mate 😊👍👍
Thanks very much for the kind words, Derek! Well, I really should have no excuse for NOT trying this myself, after all I did a 3 year apprenticeship for BT and was trained in electronic engineering at Polytechnic! I'm still a little rusty, but this is really basic electrical stuff. I know what you mean though, if you have never encountered this then it can seem a little daunting - I have to admit it took me a while to get back into it after the 30 years since I worked for BT!!! Thanks again mate, hope Sunday is going well. :)
Above and beyond the Tibster too Mark. I dont understand. But I wish i did. Its very impressive on how you work this stuff out mate. Top stuff 👍👍
Hiya Tibs! Sorry if I didn't explain it all properly, but I think it would have taken about an hour to go into all the details! The main thing is, if you get the same LEDs and resistors and copy my wiring, you should get a working set of lights! It should become apparent how easy it is in the next video when I'm not going on about Ohms Law!!! Thanks for the kind words though dude! :)
Mark even if you spent a whole dau explaining it to me, i would still be scratching my head lol
:D Never mind, I know there must be things you understand that would leave me puzzled too!
Nice choice of subject video and well presented. I agree with your comments about the fancy light set ups, all i want is 6 front white LED's and two rear red for my Lancia o37. Will you be publishing the specification of the LED's and resistors used and how to do it in the next video? Thanks for everything and looking forward to seeing it.
Hi Kevin, thank you very much for the positive feedback. So you need a similar LED set-up to me? I am not alone! :)
Yeah, I have already started filming the next video and I am showing how to connect the circuits, soldering the resistors and LEDs and connecting to the battery. I have put the specs for the LEDs and resistors in the video description. Take a look, if you need any more details, let me know. All the best, Mark... :-)
I‘m building the same Audi Quattro body kit right now for my kv-02. i bought a 20€ set of lights by killerbody. They come with indicators, break lights, and reverse lights (brighten up when reversing). I don’t want the indicators to blink every time i turn (also the reversing lights)… so i didn’t install them. I want all the lights constant lit bright. Rear lights and all the front lights. The bucket lights, the normal front lights and the rear. I have absolutely no clue about electrics and i‘ve cracked my head about this since two days. So there is only fancy stuff in the shops but not what i am looking for. You showed the solution. Subbed immediately, thank you! I also like the other videos.
My idea goes also in another direction too, i wonder what you think about it (if you have time):
I was thinking building the cockpit like you did. Now in my head i want to have a separate circuit for the lights, hidden under the cockpit. With a on/off switch, and a battery for the lights circuit. So if i detach the body everything stays in the body. I also want to build a lancia delta hf body, more for „bashing“ and the audi for the look if it. If this would be possible with independent circuits it would be great. What do you think?
Sorry for the long message and the mistakes. English isn‘t my first language. Greetings from Switzerland!
Hi there and good to know that the video was of some use! Thanks for the sub too, much appreciated!
As for your idea about the body and cockpit, I think it's great! If you use a separate 3v battery (or 2x1.5v in series) you wouldn't even need resistors! Good idea too keep everything contained in the body so you have no trailing wires!
Thanks for your message, there are no mistakes and your use of English is better than many native English speakers! All the best and Seasons Greetings to you from England!
@@MarkBryanRC thank you! I‘ll try that and let you know how it works.
I really like your channel!
Thank you very much my friend! :)
That was a really enjoyable video.
Thank you very much, It's good to know you enjoyed it, and I appreciate you leaving the comment - cheers! :-)
Try MyTrickRC. It's a good system to get, and the LEDS aren't too expensive. Don't know what the shipping costs are, though..
Thank you very much for the info my friend - I will definitely check that out! Best regards from Mark :)
Great undate brother
Thanks for the kind comment my friend - LEDs are not as scary as some might think, just need a few resistors! Hope Your weekend is going well! :)
@@MarkBryanRC your welcome and you have a great weekend brother
BTW Mate..... You didn't warn me there would be MATHS!!! 😳😳😳😖
You did a great job of keeping it simple enough.
Question though. Since you have clusters of 3 in the Spot Lights...
Would they be even brighter using 3 LEDs per 220Ω Resistors?? You should be safe @ 7.3v...
I've simplified mine, accidentally of course! 😜 My 10mm LEDs are 12v.
But that means that I could run them straight from a 3S Batry (11.1-12.4v), but if I run a NiMH or a 2S Batry (7.4-8.2v), I'll need to fit a separate 3S Batry just for the Lights...
But Brother, they will be BRIGHT!! Bright enough for the darkest Desert night. 😉
Dude!! I am so chuffed and stoked (UK/US!) to get going on this Classic old Body!
Due to TIGHT Budget, as you well know, I'm reusing the Interior from the Ford Raptor Body. I'll just make a more period correct Dashboard. I've even already got an old school Ginormous Steering Wheel. 😁
All I've had to do so far, is narrow the Seats by 1/2" each. The Cab is narrower, and of course has Running Boards! 😎
I really will try to be as detailed as possible in Video.
Haha! I love maths! It's pretty simple stuff, really. Mate, if I put 3 LEDs in series, the NiMh won't have enough forward voltage to drive them (I did experiment with that idea, but they barely glowed).
Yeah, your install will be very simple, just wire them all in parallel across a 3s, no resistors needed!
Looking forward to the upcoming video, I love the details! :-)
Mate, you and I are among a rare breed of Nerds!! My range is more in Life Sciences. Mainly Primordial Life to the Cambrian Explosion...
Maths, not my thing. 😖 My Dad.... He could do Algebraic Equations in his HEAD!! 😳
Not me. I do enjoy fiddling with Electronic and Mechanical gizmos though. I built my last 3 Computers... But needed my Brother in Law to set up the Software!
I'm currently Scratchbuilding the Interior. The Lighting comes next. 😉
Yeah - we are the super-nerds!!! :P
Bring on the interior, Carmine!
I love Scratchbuilding!! 😁 I guess it's from 40+ Years of 1/87th Model Railroading work...
Some people are so scared of it. It's actually not hard.
I found pictures of 46 Dodge Trucks and copied them! Then in 3D. 😉
..... My Nerdy side actually won my Wife! When I was DONE with groupies and blonde foam domes, I found Cindi. Almost accidentally!
She was showing someone her 450 million year old Trilobite Fossils...
And I promptly STOLE her away from the guy she was talking to!!! 😁😁
I'm partial to a bit of scratching, too, dude!
Haha! Man, you sure did it in style, winning Cindi over! So you trumped her ancient fossils with a modern bone?!?!?! :P
Wow! Taking LED’s for an RC to another level 🙂 Great job explaining. I will definitely try to remember going back to this (and the next) video if I ever try that myself. Looking forward seeing the Audi lit up. Maybe add a calculation of how many € you saved in doing this? And was it worth it in time? (I mean, was it good hobby time?)
Thanks Mikael! Well, I don't know about another level, but a hobbyists level for sure! I think I saved about 90 Euros over the Tamiya solution (TLU and LED sets). But for me, well, I think you know me by now, I always enjoy doing things my way, like the Monster Beetle Brackets, and the DT02 shock brace and the Rising Fighter Transmission Brace. I really do enjoy making my own solutions out of inexpensive parts (I am not a wealthy man!) So yeah, it really was worth the effort and I enjoyed the process - wait till you see the Audi on a dark rally stage! :))
Mark Bryan RC Will look forward to it. Yeah, if one got the brain, the hands and the time - then one might as well use it to save some money while exploring the hobby 🙂 What was it you where teaching, I forget?
Exactly! And I teach basic maths and English to 6-9 year old children!
However, when I left school all those years ago I was an apprentice for a national telecoms company, and was trained for 3 years at college in electronic engineering! :)
Mark Bryan RC Ahh, so this must be a walk in the park. I would love to learn to make my own LED sets. And light buckets too. Would love lights on some of my trucks, like the Monster Beetle, Blackfoot 3. One day when there is time 🙂 I have hesitated too because the cost, combined, is so high for a little light that even all my son’s toy-grade RC’s have.
Yeah mate, my experience means that this is quite easy for me! Hopefully the next video will show how easy it is to wire it all up - I'm just going to film that in the kitchen now! Yeah, something for a later project when there is time for you, I think you would enjoy it too. And yeah, all the toy grade RC's have LEDs because they are so cheap, actually pennies each if you buy in bulk. Pity the hobby grade manufacturers don't do the same :-/
Hi Mark, I'm doing the body now according yours very useful videos. Thanks a lot. Just one question - in my kit front light case has place for 2 LEDs - 1 for 5mm and one lower for 3mm ( orange sticker on the corner). And the rear case has place for 3 LEDs - 1 for 5mm and 2 for 3mm. So question - if they build cases for all these LEDs why they do not provide the masking for these places. Or I need to remove paint and make these places clear for LEDs? Thanjks.
Hello, friend! The masking sheet does include the masking for the places the light buckets fit. I show how to fit them in my video here: czcams.com/video/pWTQXHZEDKs/video.html
@@MarkBryanRC I watched this video. I mean that when you finished to install LEDs - your car has headlight only. Not lower turning light . Is it ok? Thanks for reply!
@@933pilgrim Sorry! Now I understand! I did not want to have any turning lights - I think the rally car would not look right if it was making turn signals every time you turn the wheels! :)
@@MarkBryanRC Oh I see... Make sense. Thanks...Sorry for newbie questions...
@@933pilgrim No worries - hope it is going well!
Can I plug LEDs set to Rx directly and used Tx switch for on/off? What color of LEDs I need - like red, orange, clear?
Hi friend, If you use the Rx connector to power the LEDs it will be only 5v, not the 7.2 I have designed my circuit to work with. You need white leds for the front and red for the rear - only use orange if you wire up the indicators, I did not use them. :)
@@MarkBryanRC For example my rc plane Eflight Cherokee used 8 LEDs and all of them just connect to Rx. I think its much easier then connect to battery. Or I mistaken?
@@933pilgrim Well my friend, if it works OK on your plane, you already proved that the method works! I would use that method as it does sound easier! :)
@@MarkBryanRC ok. will try both....
What pin is your on off switch
The on off switch is from an old ESC wired in series with the positive supply to the LEDs. :)
@@MarkBryanRC what type of switch could I use if I have to buy one. I've just ordered all the setup car lights ect need a switch. This is my first tamiya RC build.
Hi, take a look at this on eBay:
www.ebay.co.uk/itm/283997798266?hash=item421f967f
See if you can find something like this switch, it will be perfect in your LED wiring loom.
Best regards from Mark...
