A fire, and you are meat!

[MPaulHolmes]

@Kitfugl hahahaha.

[tectalabyss]

Great Job !!!! I Subscribed to your channel and thank you for sharing....Tec

[MPaulHolmes]

@tectalabyss Thanks!

[JcXtreme72]

What would Jesus drive? Him, 12 apostles and always stopping to help some one. That would be a 15 passenger van.

[MPaulHolmes]

@JcXtreme72 ROFL. That was good.

[MiggyManMike]

It's no BlackCurrent, but i like :)

[hipofalcon]

Wow - your garage looks a lot like mine - except a lot neater! Well done man!! Ken.

[totalrandomcrap]

Can it still float with all that extra weight in it?

[MPaulHolmes]

@totalrandomcrap IT's actually about the same weight as before, but with an imaginary adult sitting in the "back seat" (which no longer exists). It does float, but now you die from electrocution every time you drive it across the ocean.

[InsectsandCreatures]

Brilliant!!! Show us the diagram please!! I would definitely build my own soon.Cheers!

[TheFuscaoloko]

Yes, I wonder how fast it reaches q?

Thank you very much

in waiting

[TheFuscaoloko]

hi friend, how he reaches kilometers or miles per hour?

thank you. beautiful work

in waiting

[MPaulHolmes]

@TheFuscaoloko At 72v, I have gone around 45-50 Miles per hour.

[daswada9]

can you make it step by step and show the components that you use ?

[MPaulHolmes]

@daswada9 I did that for the controller. Check out our website for details on that. paulandsabrinasevstuff(dot) com

[maluco4life]

How much did you spend in components?

[MPaulHolmes]

@maluco4life For one controller it's around $350. It can be cheaper if you make several at the same time. Like closer to $250.

[iirmantass3]

@MPaulHolmes Hey how much miles you can do with this car? And also does it charges while you driving?

[MPaulHolmes]

@iirmantass3 Doesn't recharge while driving. Probably 15 miles.

[iirmantass3]

@MPaulHolmes Thanks for info.

[oseloth]

What is the power of this el. motor? BTW I really like your project, since I am fan of beatle and electric drive :))

[4G3NTanon]

Are you using MOSFETS or IGBTs?

[MPaulHolmes]

@4G3NTanon IRFP4668PbF mosfets.

[perezpablo75]

If you need a test dummy let me know. I'm willing to do your 144v test run.

How soon would you be able to add info of your project for others to build?

[MPaulHolmes]

@perezpablo75 check out paulandsabrinasevstuff(dot)com­. We have the help file there now.

[SouthsideHoods]

You know these project are really cool but compact isnt always the way to go. You can pull more miles and power from a off road vehicle like a jeep cherokee because of battery storage room. Think about it cause your buggy is a success.

[paytontech]

@SouthsideHoods Smaller cars usually give the best balance of weight, aerodynamics, and room for batteries.

Big vehicles are usually good on the room and bad on weight and aero.

[tdk1955]

where did you get the schematics for the home made 144v.500amp motor controller i would like to build one and i have no idea ware to get the information would you please give me the information where to go. Thanks for your time. and help.

[chr36]

Looks like you're having a great time with this fun project!

[jaldek41]

yeiiiii i blow out the fuse...!

[kdyzb]

why do you use gear box, you dont aplly the motor directly to the differntial box, ? to many loses at gear boz aprx. %35 can you explain ?

[preytec]

@MPaulHolmes well if you do, plz upload a vid so i we can see it too.. not the 30 miles. more on the set up side of things

[preytec]

cool vid, i love the car it looks so funky. i don't think i'd make one myself as i wouldn't have the know how or space but electric cars are the way of the future.

well done on your achievement

i wonder how far you could go 'per/gallon' if you put in a small diesel generator in the back running on used sunflower oil?

[MPaulHolmes]

@preytec You can get about 30-35 mph with a generator. I would like to try that.

[TheKaos90]

But you have a pretty heavy machine there , so if you go top speed and go off the "gas" andmove only from inertia , would your batteries start recharging ?

[MPaulHolmes]

@TheKaos90 if it had regenerative braking, but I don't, so it's just a waste.

[MSCompuServ]

Add some caps to improve state of charge and performance.

[MPaulHolmes]

@MSCompuServ I saw something like that with some Maxwell ultracapacitors. He got awesome performance.  Zero voltage sag on the battery pack.

[pcuser80]

I see on your controller B+ is black and B- is red

Confusing and dangerous.

[MPaulHolmes]

@pcuser80 Well, I'm the only one driving it, so it only matters if I was confused, and I wasn't so it's all good!

[selfoto]

@MPaulHolmes

Doesn't really matter, red plus, black minus. that is how it always should be. Cool car though, I love the dual voltmeters strapped to the dashboard. Haha!

[megasmart1337]

ugly shit

[Viking9280]

very impressive

[daveharpe]

I'm guessing you built your own controller because the PMCs are still blowing up. That was a big problem in the San Jose area, and a local guy started building his own with really big IGBTs. They seemed to work a lot better. I was making DC converters for the same group, but I got put out of business by some outfit that used Chinese slave labor and sold complete units for less than I could get the parts for. I am still very much interested in electric cars, but don't have the time and $ to do it

[alessandro78s4]

bravo!!! good  i miei complimenti

[ixtlau]

congra. good video

[MustangsCanTurnToo]

How much has the car cost?

[MPaulHolmes]

@MustangsCanTurnToo About $700 for everything except batteries. The batteries were $1500, but you could also get some really cheap ones instead.

[MustangsCanTurnToo]

@MPaulHolmes I have a 600 hp mustang. It has a range of roughly 200 miles on a single tank of gas before it starts to creep below the 1/8th of a tank line. It takes about $40 of premium to go that far. I discovered an equally powerful, electric Mustang with the same range but only costs about $7 to charge. It made me reconsider electric cars. Have you tested the range and speed of your car?

[MPaulHolmes]

@MustangsCanTurnToo My range is garbage. To get 200-300 mile range would require Lithium batteries. Maybe $20,000 worth.

My top speed at 72v is around 50 mph. At 144v it would be maybe 85-90 mph, and at something like 288v it could be much higher. My range is around 25 miles or something with the lead acid batteries.

[MustangsCanTurnToo]

@MPaulHolmes Awesome, thanks for the info. 

[pinkyzoey]

It looks like a jimmy rigged POS, but it uses no gas, so kudos.

[Bronnil858]

Where are you supposed to have sex with your girlfriend?

[hilololomoa]

Thanks you.keep em coming

[ftpmarco]

THUMBS UP, for the people that think we need to PIMP his ride!  X to the z

[MPaulHolmes]

@ftpmarco ROFL. HAHAHA. My wife agrees.

[Thomato80]

Nice! :) Any chance of getting hold of the plans for your controller? It looks great!

- Thomas, over in the UK

[MPaulHolmes]

@Thomato80 yes, go to paulandsabrinasevstuff(dot)com and download the directions.  Also go to ecomodder(dot)com(slash)wiki

[Thomato80]

Nice! :) Any chance of getting hold of the plans for your controller? It looks great!

[xXwhygodwhyXx]

YOU NEED A MAKEOVER!!!!!!!!!!!!!!!!!!!!

[CSRT4me]

I find it funny you can make all that, but still refer to "negative" as "minus" lol

Very nice job. love the harbor freight testers, as well! Major props and cool car.

[tommiez92]

wahts ur top speed

[MPaulHolmes]

@tommiez92 Top speed is a function of voltage. I am running 72v, so my top speed is around 45 mph. My friend in Arizona is using the controller at 144v, and his top speed is around 75 probably. He just drives freeways speeds though (they have cameras down there that take your picture automatically!) Also it uses way more power to go much faster.

[BenjaminNelson]

@MPaulHolmes

Yep, my Electro-Metro is almost exactly the same!

Top speed is about 45mph at 72V and I think I would hit about 75mph at 144V.

In actual real-world testing, I hit 72 in a 55 zone, but had to start slowing down, because I knew where the cop hides!

[luc59457]

@MPaulHolmes Top speed is not necessarily a function of voltage to some degree.

[UbeefHooked]

Looks like a death trap, are you still alive?

[MPaulHolmes]

@UbeefHooked Nope. I'm typing this from the great beyond... :)

[richardmaudsley77]

@UbeefHooked Looks like a VW and some batteries to me. What is your point?

[UbeefHooked]

@richardmaudsley77 ah, test driving down a residential street whilst holding a camera in one hand and the safety lead between his legs!! Sadly, he's already passed away, I just wished he was more careful :)

[richardmaudsley77]

@UbeefHooked See, safety lead right there. Couldn't be more safer than that.

[FilippoGatti1991]

If we find a clean way to produce electrical power for electric motors, oil will be fucked! We need also to find a way to reduce the weight of the accumulators.

[allawayjared]

I'm working on my electric car. I'm also paying for some other things so I have to buy pieces at a time. I'm almost to the point where I can put batteries in it. I will have to buy a charger after that. I posted a video response showing my most recent look under the hood. I'm using a Logisystems 120-156 volt, 1000 amp controller with 0-5K logrythmic potentiometer. I know I need a relay for the ignition, do you have any suggestions/tips/advice/walkth­roughs?

[MPaulHolmes]

@allawayjared Awesome! I don't know anything about Logisystems, but what I do is precharge the capacitors (with around 100 Ohm, 10 watt resistor), and then close the main contactor.

[MPaulHolmes]

Best $1.99 I ever spent! hahaha

[Product0fGrace702]

how far along do you think it will be till we all use fully electric cars?

[MPaulHolmes]

a long time. haha. but it would be nice for the air outside not to smell better after it rains.

[Product0fGrace702]

guess that depends on where you live.Here in Las Vegas Valley it smells like wet sage after it rains. But I'm sure your right and it's better than breathing smog all day.

[miz1981]

are u using a dc motor? and regening??

[MPaulHolmes]

DC motor, but no regen. I'm working on an AC inverter that will have regen though.

[NigelLoller]

Hi Paul

Could I build a controller for a warp9 motor running at 120volts and up to 750amps? Can solder and can read wiring diagrams can't afford soliton1 controller!!

Do you yet have a wiring diagram available( to purchace) and how cost effective is buiding your own?

Your video is very inspirational

[MPaulHolmes]

Check out ecomodder(dot)com /wiki It has a free schematic, and 50 page how to assemble directions, Bill of Materials, etc...

[dhymers]

I'll buy your old Curtis if you still have it kicking around ? :) lol

[klaaparen]

Your EV is one of the coolest ones I've seen! Great job, especially the controller. How much time did you spend? Are the parts hard to find or expensive?

[matthewm0311]

"ok that was irresponsible" haha it had to be done

[420gdub]

u converted a bug to an electric car. thats sick. good investiment

[ontheedge1979]

Are you going to be selling these controllers? Do you have a website? Can you list the specs, motor, batteries, etc...? Thanks

[MPaulHolmes]

Hello! It can take anything from 0-144v input. 500amps works fine. Here's our website:

paulandsabrinasevstuff(dot)com

[sockosockosocko]

congrats! so it out-performed your curtis controller? could it replace my curtis 123c?

[MPaulHolmes]

Beta testing is beginning at 144v, so we'll see what happens.

[dual85]

KooL. Do you happen to have a schematic for your power electronics? I feel compelled to create a high power control board, have been for some time. Thanks for your help.

[MPaulHolmes]

check out ecomodder(dot)com. Search the fossil free fuel forum for Paul & Sabrina's cheap 144v motor controller.

[ajloder10]

That is extremely awesome and impressive! Great job, and awesome car choice too! :D

[MPaulHolmes]

Thanks! I sent it to Ben Nelson for 144v testing, so be sure to check out his videos. Search youtube for bennelson.

[paulbilek]

Excellent. Thank God for people like you.

[d3adp001]

very nice, no high hz whine like most controllers.

[bodidarma505]

great job, can't wait to see more!

[user100ja]

Congratulations on success

[evric2008]

Success ! Fantastic... Congratulations.
