Great episode, Matt - they used brushes like that on the Panavia Tornado to cover the slots in the fuselage that the wings swept into, so you're using an aerospace solution, not an indoor one... 😆
They also ados f2'd a strip of balsa wood to limit travel on the later f105 ailerons at the upper limit to stop an end travel flutter from tipping them on their lids during sudden cross wind corrections those little wings did not do a lot at 200 mph.

@@9HighFlyer9 I was going to mention the main gear on the 737 as well. It uses brushes around the wheels along with a smooth "hubcap" to smooth the airflow over the retracted gear without the complication, weight, and additional maintenance of gear doors.

I can related to the middle finger up hand signal displayed to parts of the project that tested your patience for too long. I can also related to the problems we bring on ourselves by a decision made early on to take a certain route for solving a problem.
I'm with you 100%. But you left out the biggest issue. I wholeheartedly applaud Matt for realizing it was a PITA and....(drumroll here) chucking it, and going back to the original idea. Even after spending so much time and money. That's a personal trait (quality?) I lack. GJ
I was going to say exactly this... rusefi proteus has DBW as well as a huge amount of digital, analog, can channels for other 'simplification' options. Uses tunerstudio just like the MS too.
Awesome content. Keep up the great work. You're one of few people that can show the struggle of r&d / engineering and make it super informative and entertaining. Favorite channel.
@15:06 You can drill aluminum with this equipment, but for best results you have to set the spindle speed between 2,000 and 4,000 RPM, you need to do short 0.03" to 0.06" pecks so chips can clear on their own, and to avoid having the drill bit walk or deviate the shortest bit you can manage to get ahold of will be best. I tend to not use drill bits that are any longer than the router bits I'm using.
Short drill bit is a good idea. we did have some walking but it seems to be within reasonable tolerance. We definitely should have peck drilled. next time for sure.
@@SuperfastMatt Stop bleeding brakes at the caliper nipple. Get a big plastic syringe and FILL the system from the caliper nipple, pushing the air up to the master cylinder instead of trying to get it to come out on the low end. Friend of mine once bled my motorcycle brakes that way Took about 10 minutes, no spillage, no mess ...
@@SuperfastMatt the little carbide PCB drills you can buy on McMaster and other places are lovely for drilling on a router. They are cheap and incredibly good in almost all materials. If you're drilling up to 1/8" diameter give em a try. M.A. Ford makes the ones from McMaster and their recommended parameters are bang on. I tend to peck them at .25xD when drilling dry or near dry. Ethanol mist (Or isopropyl if that is what you have) works very well as an aluminum cutting coolant for a router, which will not make a huge mess. You don't need much.
Speedometer screen: first number gear, next three; speed; or opposite; first three for speed, last for gear. Second screen: Revs. Also, I don't know how you do cabling, i don't know if anyone's recommended it before, but I'm just gonna mention 'controller' cables real quick, as you can buy them in bulk. They might have a different name than the literal translation from Icelandic to English over there, but it's basically the 'standard' name for a cable with multiple, usually minimum of 6 conduits, so for your scenario, you could for example, decide to always have conduit no 1 as ground, and then whatever you need with the others. I believe they come in versions ranging from 0.3mm2 (~35awg) to at least 2.5mm2 (14awg) and from what I saw, they can contain up to 24 conduits, and I would not be surprised if they could contain more.
Hi Matt for the electronic position sensor you opened, it might be possible to reverse engineer it using the part numbers on the PCB, I did that in a previous project. If you post a high resolution picture of the PCB (or scan it on a flatbed scanner), I can see what I can do.
looks like an induction rotary encoder. what protocol it might use is more difficult with just three wires, so not can or i2c. maybe some high speed rs232.
Nice seeing your vids. It is what got me interested in land speed again. when younger mid 1980s after getting in way over my head at 200mph on the Interstates around Chicago. Two of our group perished within 3 months. I figured i'd die and I had a young 1yr old, a family! So having kids and all decided on the offroad / motocross arena. Sold all my street bikes and gear, replaced that with offroad gear, raced on tracks only, and never looked back. We'll Kids are grown , I became a tool and die maker. Now I can machine an entire engine and nearly every part within one very well. And somehow after your last vid? A clapped out 1985 Cagiva 2 stroke factory gp bike fell inside my garage. Its a mystery lol (engine is complete and not broken!!!) Maybe I'll see ya in a year Matt. Good luck and be safe! P.S. I have really appreciated you sharing your journey. It fills a hole in folks lives and sometimes inspires them (me!) to get up and move too!
matt, i couldnt tell the orientation of your print for your handlethrottle. print an extra for your race. I found that polycarbonate, while strong, will still just as easily seperate along its print lines as other material. Also, pay attention to how hot any of your printed parts will get. PLA will droop almost immediately at even low temps and a small load (look at their datasheet, glass temp?).
Polycarbonate generally has not great layer bonding. Nylon or PET would be a better choice. You have to be careful with nylon because it distorts as it absorbs moisture. PET is relatively new in 3D printing so there are some unknowns. In any case, I wouldn't trust my life to a 3D printed part of any material without an extreme amount of failure testing. For example as the throttle link. Especially not printed in that orientation where the cable captures can easily shear off along the layer lines.
I can only imagine the psychological damage that might be done to a person sitting in a portable toilet when a car runs into it at high speed provided the person relieving themselves survives. It would certainly resolve any issues the person might have with constipation. Also the new safety requirements of roll cages and other items Osha would place on portable toilets at automotive events.
You could use a spring on the fire extinguisher door if the rules allow it. It doesn't have to be too strong of a spring. The pressure delta should help keep it closed.
Over the years I've discovered the wonderful thing about a project is how overjoyed you'll be to no longer have to work on it. Keep Pushing through, Matt.
Protip: for the speedo issues, pick up a mychron 5. Customizable interface, and super accurate gps speedo. You can also keep track of tons of different temps and other goodies. Ask any karting guy, they're awesome
Have you thought about taking a look at aviation for the fire door? I used to work on a Jet Provost which had spring loaded fire doors. You could push the doors open by hand, so there's not a huge amount of spring pressure. But it was enough to keep the doors closed and flush to the fuselage during flight.
For the BMW gear (and speed, and lean angle) sensors I found the easiest way to do it is just get the values from the CAN bus. I created a data logger for my 2016 S1000RR track bike and getting the values from CAN was the easiest though the microcontroller you selected doesn't have CAN support :( (I used a Teensy on the bike). CAN bus is available from key or alarm connectors (as well as others)
A couple of those letters (like N and R) would need an 11-segment display (with diagonals), not a 7-segment one; and you'd still never get T to work, it would have to look like an upside-down L.
For the fire extinguisher hole could you use a door on the side like your second one but just have it spring loaded? It holds itself closed with spring pressure, you push it open and then it snaps closed again on it's own. Like the hand holds and foot holes on the side of aircraft used for pre-flighting.
I to get great pleasure in giving the finger to my "projects/ideas" that complicate my life while I'm simplifying my life. Love the video! Good luck in the desert!
"Why are we doing this?" and "What benefit is there to doing this?" are ALWAYS good questions to ask at any time on any project. That's a lot of work and burn out must be a real problem. Best of luck! 👍
Use your ag1 money and buy a haltech ecu and then you can use any electronic throttle pedal and any dbw throttle body, itll also tune itself if you install a wideband o2 add on, itll also do all of the canbus micro controller stuff your doing out of the box with their display unit, yes can be costly but honestly takes so much pain out of the process, can even chuck in alot bigger injectors and just change the injector cc size in software and it will automatically adjust your fuel mappings.
If that ad 1:49 was about 12 seconds longer, i might consider thinking about the possibility of a parallel universe where i'd be purchasing that drank. I wanna see your facial expression after finishing that murky bog water. 😂 Anyway hail to the mighty algorithm.
Post a high resolution pic of the top and bottom of the sensor board and I'll tell you how to read it. Please make sure the part number of the IC is visible. Also, what motorcycle is this off of? Pulling the service diagram may reveal which wires are power and ground.
Just a thought - maybe consider printing that throttle in halves split along a plane coincident to the handlebar axis. That way the layer lines are continuous through your part and will be stronger in shear. I have to imagine that the throttle shearing off at 150+ would be less than ideal. Like I said, just a thought..
Sure, we have stainless oven and microwave, white fridge and white freezer that don't exactly match. All bought at different times, some in a previous house. Not going to throw away good appliances just to match colours. It's fine, nothing to see here.
@@En_Joshi-Godrez how did you know about my recent redundancy that didn't affect my self worth at all and is about to become a 30k pay rise? Man you're clever! Hats off. But fuck AG1 and the soulless scammer behind it. Look into it. Bad news end to end. There's plenty of dull boring shit sponsorships, a handful of good ones like proton VPN, and a bunch of ones only the worst most desperate YTers push, betterhelp, AG1, established titles, and others. We thought Matt was above shilling for low end scum like that. :-(
I admire your humility. I think building such things tends to generate humility. I wonder why my dad, who did such building, never got that humility stuff. Oh well. You hate bleeding brakes too? Small world. There must be clever kits for the process. Brake bleeding has been a major pain for too long.
The more I'm forced to work with industrial micro controllers like rockwell PLCs the more I fall in love with arduinos and basic electromechanical components like basic relays.
I totally agree that if you can do it simpler go for it :-) And simpler is relative to whatever you feel good at hehe. In case anyone wonders though - the flapping problem on the throttle with my ETC is usually to do with too high gain of the error amplifier in the PWM controller. To put it simply it has a too fast response. The solution for that is making R7 value smaller and/or R8 larger (for example 10k->1k and 1k->2.4k respectively). I've actually added it as a hint recently to newer version of the calibration spreadsheet. I guess that's one of the prices we pay for an "elegant" analogue design - not that flexible/easy to modify as a SW solution. In my latest design of ETC that is similar to v2.2 byt dedicated to be built into Speeduino ECU I've added some extra pads and resistors to make exactly that mod easier. And sparking od Speeduino - it's similar in capabilities to MegaSquirt but it's like going back to the roots back when MS was cheep and DIY. It seems over the years it became more expensive without bringing much more to the table. Interestingly Speeduino also uses TunerStudio for GUI so it's even not that painful to switch (even though MS is not that popular in Europe anymore I actually do have it in one of my cars. And it can be a pain in the ass sometimes). In case someone is looking for an off-the-shelf ECU solution in relatively low price try the polish EMU from ECUmaster.

From what I could see of the smashed sensor, it looks kind of like Capacitive sensor. There is no wizardry you are going to wield that will give you a restive output.
For the barrel sensor, Is a Hall effect sensor. It measures the strength and direction of a magnetic field. Probably needs a 12v feed, gnd and the signal would be 0-5v

Dump the mega squirt and go with a Holley or even better FuelTech. Much better you won’t regret it. I did and it was a night and day difference. Well worth it. Better tuning. Can-bus wiring! Just look in to it!!! Nice project good luck stay safe!
Mediocre electromechanical engineer here, that shift position/throttle position sensor looks to me like an inductosyn, with the input of an alternating current, it outputs an alternating current for cosine and sine, depending on the angular position, the amplitude of both output signals vary, regardless I have no idea in what protocol it outputs data, but I do know how it functions
One small part becoming an achilless heel of a whole project (or sub-project) is a very familiar problem to me. And freaking always instead of trying to find a way around I just overcomplicate and bang against the wall trying to make it work but it just doesn't. Sometimes someone comes and gives helpful information and I get to go on. Sometimes I'm stuck in a torture and a broken skull near the frontal lobe.
Can we agree that taking a sponser is great for Matt and the projects. Eventhough it might be a scam. It will help to bring more videos. The algorithm also loves all the comments. - Glad to see the Lands speed car finaly 80% finished.
A lot of people seem not to realize that the entire supplement industry is equally unregulated and that AG1 isn’t remotely unique in its scam-ness. They’re right to resent scams making money, but go after the reason these scams exist: Republicans blocked efforts to curtail the supplement industry’s immunity to ingredient validation in the 90’s. They even got Mel Gibson to do TV ads about a made up fantasy of the fbi raiding your kitchen for your work out supplements
I like simples, it’s why I raced with two SU carbs. They would run with fuel coming out of the overflow. . . . down the drain pipes . . . . and running through the bulkhead :o) (it was climbing a cliff at the time)
That fancy gear-selector potentiometer probably produces a square wave output, which varies the high/low time in relation to the signal change. Check that using an oscilloscope. I cannot tell you, how to wire it. But try following those wire/traces, lookup the IC datasheet or look at components(e.g. capacitor polarity) and try figure out which wires need power/ground or output the signal.
Man, this video reminded me why I should have ditched Megasquirt way sooner that I did on my project car. I spent more money and time on the Megasquirt part that I did when I switched to Ecumaster and payed a professional to do the wiring, setup and tuning.
Solution for the fire door handle: drill a hole, run a metal wire attached to a weight on the other end, and design an aerodynamic shark fin knob you can pull. Weight will pull it down so it sits flush after it’s shut, but the wire allows it to extend out when pulling it shut. It’ll be way easier to pull shut than having a knob attached to the lid that won’t articulate due to it being in the center, especially with gloves on.
I dont mind your sposorship choices, if thier money helps you project, I'm fine. I was taught as a child not to believe in ads.... This aside, i love your videos.
Is AG1 a scam. Yes. Do i think matt should stop taking their money? No. Scamming scammers is ethically positive. Yall just keep pointing out the scam in the comments for him and he gets a race car and we get to see it!
They sell various Hall position sensors for measuring shaft position. The cheapest is just a 0 to 5 volt analog output, like used on eBike thumb throttles, sell for about $10. or build your own for the cost of the hall sensor and 2 magnets. The other more fancy hall sensor (AS5048A) reads out 0 to 360 degrees using SPI output. Can be hooked up to an Arduino directly.
Masso g3 touch. they're nice if you can cope with the limitations - very good a running Gcode, not great for running a machine in the semi-auto way that you often do for prototyping. (IMO)
10:49 I work in electrical engineering and I can tell you 100% you can't read it. It looks to me, and this is only a cursory analysis, but it looks to me like you smashed it with a hammer. Once you smashed it with a hammer, you can't read it.
Just angle grind it, make a electromechanical solution, send cut send a plate, glue it together. Now you have the fast matt Gear system. For speed you need to know the tire diameter well, if you manage that, just throw in a mechanical Speedometer. Or do a optical encoder wheel. Side note, you can also use a encoder or optical encoder on the gear sensor. For now, use the accelerator to know when in neutral.
You should try hooking up two identical Stepper Motors together as a makeshift fly-by-wire throttle body. They will (in theory) move identically to one another (Test this out before putting it on the car so you don't die) One disadvantage is any movement of the throttle body motor will turn the handlebar motor the same amount and with the same force, so should something snap/break/go wrong, it could break your wrist. Cheers from The KSA
On electronic control I’m a fan of the fueltech systems many drag racers use, they’re fairly customizable, to the point of being able to control boost and timing by speed and time, traction control, etc…

I can related to the middle finger up hand signal displayed to parts of the project that tested your patience for too long. I can also related to the problems we bring on ourselves by a decision made early on to take a certain route for solving a problem.
I'm with you 100%. But you left out the biggest issue. I wholeheartedly applaud Matt for realizing it was a PITA and....(drumroll here) chucking it, and going back to the original idea. Even after spending so much time and money.
That's a personal trait (quality?) I lack. GJ
Rusefi is an open source ECU, has drive by wire built in, uses tuner studio, and they have an ultra affordable version that is just $175
I was going to say exactly this... rusefi proteus has DBW as well as a huge amount of digital, analog, can channels for other 'simplification' options. Uses tunerstudio just like the MS too.
And Speeduino! Which I happen to have one laying around.
Awesome content. Keep up the great work. You're one of few people that can show the struggle of r&d / engineering and make it super informative and entertaining. Favorite channel.

@15:06 You can drill aluminum with this equipment, but for best results you have to set the spindle speed between 2,000 and 4,000 RPM, you need to do short 0.03" to 0.06" pecks so chips can clear on their own, and to avoid having the drill bit walk or deviate the shortest bit you can manage to get ahold of will be best. I tend to not use drill bits that are any longer than the router bits I'm using.
Short drill bit is a good idea. we did have some walking but it seems to be within reasonable tolerance. We definitely should have peck drilled. next time for sure.
@@SuperfastMatt Stop bleeding brakes at the caliper nipple.
Get a big plastic syringe and FILL the system from the caliper nipple, pushing the air up to the master cylinder instead of trying to get it to come out on the low end.
Friend of mine once bled my motorcycle brakes that way
Took about 10 minutes, no spillage, no mess ...
@@SuperfastMatt the little carbide PCB drills you can buy on McMaster and other places are lovely for drilling on a router. They are cheap and incredibly good in almost all materials. If you're drilling up to 1/8" diameter give em a try. M.A. Ford makes the ones from McMaster and their recommended parameters are bang on.
I tend to peck them at .25xD when drilling dry or near dry. Ethanol mist (Or isopropyl if that is what you have) works very well as an aluminum cutting coolant for a router, which will not make a huge mess. You don't need much.

Speedometer screen: first number gear, next three; speed; or opposite; first three for speed, last for gear.
Second screen: Revs.
Also, I don't know how you do cabling, i don't know if anyone's recommended it before, but I'm just gonna mention 'controller' cables real quick, as you can buy them in bulk. They might have a different name than the literal translation from Icelandic to English over there, but it's basically the 'standard' name for a cable with multiple, usually minimum of 6 conduits, so for your scenario, you could for example, decide to always have conduit no 1 as ground, and then whatever you need with the others.
I believe they come in versions ranging from 0.3mm2 (~35awg) to at least 2.5mm2 (14awg) and from what I saw, they can contain up to 24 conduits, and I would not be surprised if they could contain more.

Hi Matt for the electronic position sensor you opened, it might be possible to reverse engineer it using the part numbers on the PCB, I did that in a previous project. If you post a high resolution picture of the PCB (or scan it on a flatbed scanner), I can see what I can do.
looks like an induction rotary encoder. what protocol it might use is more difficult with just three wires, so not can or i2c. maybe some high speed rs232.

Nice seeing your vids. It is what got me interested in land speed again. when younger mid 1980s after getting in way over my head at 200mph on the Interstates around Chicago. Two of our group perished within 3 months. I figured i'd die and I had a young 1yr old, a family!
So having kids and all decided on the offroad / motocross arena. Sold all my street bikes and gear, replaced that with offroad gear, raced on tracks only, and never looked back.
We'll Kids are grown , I became a tool and die maker. Now I can machine an entire engine and nearly every part within one very well. And somehow after your last vid?
A clapped out 1985 Cagiva 2 stroke factory gp bike fell inside my garage. Its a mystery lol (engine is complete and not broken!!!) Maybe I'll see ya in a year Matt. Good luck and be safe!
P.S. I have really appreciated you sharing your journey. It fills a hole in folks lives and sometimes inspires them (me!) to get up and move too!
Glad to hear that the lack of videos is just cause you’re busy doing stuff on the car and not anything serious. Good luck with the speed runs
matt, i couldnt tell the orientation of your print for your handlethrottle. print an extra for your race. I found that polycarbonate, while strong, will still just as easily seperate along its print lines as other material.
Also, pay attention to how hot any of your printed parts will get. PLA will droop almost immediately at even low temps and a small load (look at their datasheet, glass temp?).
Idk why i posted this. Just watched your 3d printer video. You definitely know more than me lol.
@@ryanfoss6243 I know nothing of the said subject matter. But I applaud your humility. You'll go far.
If it snaps at speed, he's fucked. So yes, the concern is real
Polycarbonate generally has not great layer bonding. Nylon or PET would be a better choice. You have to be careful with nylon because it distorts as it absorbs moisture. PET is relatively new in 3D printing so there are some unknowns. In any case, I wouldn't trust my life to a 3D printed part of any material without an extreme amount of failure testing. For example as the throttle link. Especially not printed in that orientation where the cable captures can easily shear off along the layer lines.
I can only imagine the psychological damage that might be done to a person sitting in a portable toilet when a car runs into it at high speed provided the person relieving themselves survives. It would certainly resolve any issues the person might have with constipation. Also the new safety requirements of roll cages and other items Osha would place on portable toilets at automotive events.
I think OSHA would probably make the reasonable suggestion to move the toilets first..
You could use a spring on the fire extinguisher door if the rules allow it. It doesn't have to be too strong of a spring. The pressure delta should help keep it closed.

Over the years I've discovered the wonderful thing about a project is how overjoyed you'll be to no longer have to work on it. Keep Pushing through, Matt.
Can totally relate to spending so much time and effort prepping a race car that when race day arrives the motivation is completely spent…

@@zachmaster426no
Just skip it. Can't believe it bothers you that much
Have you thought about taking a look at aviation for the fire door?
I used to work on a Jet Provost which had spring loaded fire doors. You could push the doors open by hand, so there's not a huge amount of spring pressure. But it was enough to keep the doors closed and flush to the fuselage during flight.
For the BMW gear (and speed, and lean angle) sensors I found the easiest way to do it is just get the values from the CAN bus. I created a data logger for my 2016 S1000RR track bike and getting the values from CAN was the easiest though the microcontroller you selected doesn't have CAN support :( (I used a Teensy on the bike). CAN bus is available from key or alarm connectors (as well as others)
Best of luck on your runs! I hope things go so well that you are both surprised and pleased.
That is actually a thing that happens. So I'm told. 😅
08:25 Gear indicator NEUT FIRS SECO THIR FOUR FIFT 😁
A couple of those letters (like N and R) would need an 11-segment display (with diagonals), not a 7-segment one; and you'd still never get T to work, it would have to look like an upside-down L.
For the fire extinguisher hole could you use a door on the side like your second one but just have it spring loaded? It holds itself closed with spring pressure, you push it open and then it snaps closed again on it's own. Like the hand holds and foot holes on the side of aircraft used for pre-flighting.

You never fail to keep it interesting!
Definitively THE coolest project on this channel
taht gear selector looks like a hall effect sensor, not a potentiometer
Use your ag1 money and buy a haltech ecu and then you can use any electronic throttle pedal and any dbw throttle body, itll also tune itself if you install a wideband o2 add on, itll also do all of the canbus micro controller stuff your doing out of the box with their display unit, yes can be costly but honestly takes so much pain out of the process, can even chuck in alot bigger injectors and just change the injector cc size in software and it will automatically adjust your fuel mappings.

Love your vids and the frequent upload👌🏻
Good luck on the flats. Can’t wait to see the car covered in stickers!
The "potentiometer" is likely actually a quadrature rotary encoder.
Just a thought - maybe consider printing that throttle in halves split along a plane coincident to the handlebar axis. That way the layer lines are continuous through your part and will be stronger in shear. I have to imagine that the throttle shearing off at 150+ would be less than ideal. Like I said, just a thought..

Anyone? Anyone?
The more I'm forced to work with industrial micro controllers like rockwell PLCs the more I fall in love with arduinos and basic electromechanical components like basic relays.
I totally agree that if you can do it simpler go for it :-) And simpler is relative to whatever you feel good at hehe.
In case anyone wonders though - the flapping problem on the throttle with my ETC is usually to do with too high gain of the error amplifier in the PWM controller. To put it simply it has a too fast response. The solution for that is making R7 value smaller and/or R8 larger (for example 10k->1k and 1k->2.4k respectively). I've actually added it as a hint recently to newer version of the calibration spreadsheet. I guess that's one of the prices we pay for an "elegant" analogue design - not that flexible/easy to modify as a SW solution.
In my latest design of ETC that is similar to v2.2 byt dedicated to be built into Speeduino ECU I've added some extra pads and resistors to make exactly that mod easier.
And sparking od Speeduino - it's similar in capabilities to MegaSquirt but it's like going back to the roots back when MS was cheep and DIY. It seems over the years it became more expensive without bringing much more to the table. Interestingly Speeduino also uses TunerStudio for GUI so it's even not that painful to switch (even though MS is not that popular in Europe anymore I actually do have it in one of my cars. And it can be a pain in the ass sometimes).
In case someone is looking for an off-the-shelf ECU solution in relatively low price try the polish EMU from ECUmaster.

@@mhenlopotter1612James Smith and Bryan Johnson have videos critiquing the product. AG1 basically doesn’t have to list the amount of every ingredient included in the product, can overcharge the customer and gives influencers huge commissions.

Dump the mega squirt and go with a Holley or even better FuelTech. Much better you won’t regret it. I did and it was a night and day difference. Well worth it. Better tuning. Can-bus wiring! Just look in to it!!! Nice project good luck stay safe!
Mediocre electromechanical engineer here, that shift position/throttle position sensor looks to me like an inductosyn, with the input of an alternating current, it outputs an alternating current for cosine and sine, depending on the angular position, the amplitude of both output signals vary, regardless I have no idea in what protocol it outputs data, but I do know how it functions
Don't inductosyn encoders have more contacts? everything I've seen shows 6 or more pins of these types of encoders.
@ yes, but I believe the circuit bord inside the sensor takes care of that and generates some sort of signal, which probably only the BMW ecu can read
Great job on the video Matt! Thanks for making it.
I really enjoed your face when you were drinking ag1 scam
One small part becoming an achilless heel of a whole project (or sub-project) is a very familiar problem to me. And freaking always instead of trying to find a way around I just overcomplicate and bang against the wall trying to make it work but it just doesn't. Sometimes someone comes and gives helpful information and I get to go on. Sometimes I'm stuck in a torture and a broken skull near the frontal lobe.
Can we agree that taking a sponser is great for Matt and the projects. Eventhough it might be a scam. It will help to bring more videos. The algorithm also loves all the comments. - Glad to see the Lands speed car finaly 80% finished.
How about he gets paid to build the car, and we get to call it a scam in the comment section. Sounds like a good deal to me.
A lot of people seem not to realize that the entire supplement industry is equally unregulated and that AG1 isn’t remotely unique in its scam-ness.
They’re right to resent scams making money, but go after the reason these scams exist: Republicans blocked efforts to curtail the supplement industry’s immunity to ingredient validation in the 90’s.
They even got Mel Gibson to do TV ads about a made up fantasy of the fbi raiding your kitchen for your work out supplements

I cannot tell you, how to wire it.
But try following those wire/traces, lookup the IC datasheet or look at components(e.g. capacitor polarity) and try figure out which wires need power/ground or output the signal.

No stickers?
Solution for the fire door handle: drill a hole, run a metal wire attached to a weight on the other end, and design an aerodynamic shark fin knob you can pull. Weight will pull it down so it sits flush after it’s shut, but the wire allows it to extend out when pulling it shut. It’ll be way easier to pull shut than having a knob attached to the lid that won’t articulate due to it being in the center, especially with gloves on.
You could also make the entire door springlaoded. No closing needed for that.

It's a pyramid scam, in many cases.
They sell various Hall position sensors for measuring shaft position. The cheapest is just a 0 to 5 volt analog output, like used on eBike thumb throttles, sell for about $10. or build your own for the cost of the hall sensor and 2 magnets. The other more fancy hall sensor (AS5048A) reads out 0 to 360 degrees using SPI output. Can be hooked up to an Arduino directly.

For speed you need to know the tire diameter well, if you manage that, just throw in a mechanical Speedometer.
Or do a optical encoder wheel.
Side note, you can also use a encoder or optical encoder on the gear sensor.
For now, use the accelerator to know when in neutral.

Dislike given
You should try hooking up two identical Stepper Motors together as a makeshift fly-by-wire throttle body. They will (in theory) move identically to one another (Test this out before putting it on the car so you don't die)
One disadvantage is any movement of the throttle body motor will turn the handlebar motor the same amount and with the same force, so should something snap/break/go wrong, it could break your wrist.
