Wrangler: Flat out cheesy looking.............Slingshot hood vent: Ridiculous price............Slingshot stickers: Plagiarism, and so not at all original...........
Mustang: Not bad, good price too................2 x 3D fake vents: Very realistic, good price, best of the bunch.
Ya think so? :huh:

I ain't lookin' ta buy any of 'em
...just lookin' (for ideas & such) :thumbsup:

As for plagiarism, Ima not a makin' a bunch of these & selling them for profit
...it's art
...it's a replica of a Slingshot
...& a "tribute" to the Slingshot :bannana:

If ya was makin' a replica of a Corvette (or Jeep or '57 Chevy etc.)
...would ya call it a Corvette (or Jeep or '57 Chevy)
...or Covette ta NOT get in trouble (or Jep or '57 Cheby)

So, currently (he, he) Ima thimkin' maybe something like this :2guns:(see first pic)

SAM_3532.JPG
Which is kinda like ya see on the blue Slingshot (second pic)
...but, Ima thinkin' ta incorporate the "name" right into the stripes (ta be a bit more "original" & 'cause there ain't a lot of room on my hood)
...& (like I said before) I'll probably use a different font, for the "name" cut out(s) (ta avoid issues) :sifone:

Okay, I cede the plagiarism to a one-off piece of art. What about the originality on the louvers? Really should be your own.
Well, Ima thinkin' the louvers (if I go that way)
...are gonna be (satan or flat) black vinyl same as the "hood stripes" (shown in the drawing above)

Something like in the small drawings, in the pic below :thumbsup:

Ima gonna try-n-get a bit creative with 'em :cheers2:
...but, keep 'em simple
...& still kinda resemble the "original" ;)

Also, keep in mind that my hood is quite different (original) than a Slingshot hood :cool:
...& as such, the louvers & stripes will/are gonna be, quite a bit different (original) too :sifone:

All "still up in the air"
...we'll just have ta see what I come up with :popcorn:who knows? :unsure:

Well, I finally went ahead & put a coat of paint on the hood
...& for this one, I tried something different :thumbsup:

I used some Gloss White Rustoleum Oil Based paint
...but, I thinned 'er out (ta make it sprayable)
...& also, added some hardener (ta well, make 'er harder)
...so, now it's 2K Rustoleum ;)

* This Rustoleum oil based paint is already really durable (I've used on truck frames for years)
...bit, when ya add hardener to it, I found that it turns out kinda like "eggshell" tough :2guns:

** I also, sprayed a bumper piece that goes on my truck (had ta do a small repair)

*** Also, also, A dumb :censored: stupid bug got the bright idea ta land in my beautiful, fresh, wet paint job :furious2: :mad2:
...then, later, I noticed that he brought "friends" (there's like (6) stupid bugs in my paint job) :ack2:SAM_3538.JPG

Here's a few more pics :popcorn:
...after wet sanding them stupid bug "bodies" outta my paint job :cheers2: (with 1,000 grit sand paper)

I got most of 'em out
...so, it's NOT exactly perfect :huh:
...but, art NEVER is :smartass:

All-n-all, I think it turned out pretty kool ;)
Ima kinda likin' it:sifone:

Yup, I'd have ta agree :cheers2:

I've used some 2K automotive type paint on a few of my karts (!ARRIBA!, Damien, El Mini, Excalibur & Torsk) :thumbsup:

They turned out really nice :2guns:
...but, it seems to scratch & chip really easily :huh::furious2:
...& there's NOTHING worse than to have a nasty "gash" (scratch) in an otherwise beautiful finish :ack2:

So, this is "a test" ta see how much more "hardy" this "finish" is/will be than them automotive paints ;)

You've got production quality work there. I know it's ridiculously long and difficult to do everything needed to get that kind of quality product, so double kudos to you for the effort.
Thanks! :cheers2:
...just doin' my thing ;)

Tryin' ta "lead by example" :innocent:
...ta show folks what ya "can do", in your back yard, with standard, easily accessible materials :2guns:
...plus, a little bit of hard work

& (more importantly) :thumbsup:

My father always told me "If your gonna do something, ya might as well do it right" :sifone:

Ready for some "Arts & Crafts"?

I have some orange vinyl
...so, I figured I would try-n-do-some-creatin' ;)

* FYI: this is just a "test piece"
...just ta "see", how it would look
...& for "fitment" purposes too :thumbsup:

Ta do it, I measured & marked, the main shape
...then, "roughly" drew out the "Slingshot" name
...& then, cut 'er out (all as per my drawin') :2guns:

So it should look something kinda like this :sifone:

I layed 'er on the hood, just ta "see" ;)

Hmmm...Not Bad, Not Bad at all I must say :thumbsup:

Next, I cut out the "name" with an Exacto knife
...& layed 'er on 'er again

Yup, "that's what I'ma talkin' about" :banana:

Don't know what's better, the patience of a saint, or the patience of an ain't, looks like you might have a little of each to get that cut out half decent with that dangerous Exact-O. If it were me I'd either have given up or gotten lost looking for my butterfly bandages and gauze.
I'm carrying around a gallon of other people's Type A-positive, and only a little less than 1/2 gallon of my own that I had left. That's why I sometimes instinctively stop and think and maybe shy away from the assorted kinds of razorblades on my bench, got to be responsible with those gifts they gave to bring me back. Especially since I can't donate in kind to repay, they won't take mine.

Um...OK...it's just a pencil/pen with a "different" tip :thumbsup:
...just gotta "stay outta it's way" ;)
...or better yet, make sure it knows "whose in control" :sifone:

As far as "stripe" fitment
...it just didn't look "right" :huh:

So, when I made up a piece for the left side, I made the "wide part" of the stripe kinda "kick back" a bit (~1") :2guns:
...instead of it just going straight down

Yup, Ima likin' that better :bannana:

I think, I've come up with/finalized
...the design for
...the decal for
...the "shaker" vents ;)

*Yes, it's gonna drop down to the lower lever (I know it kinda looks weird & outta proportion)
...but, I think it'll look OK & represent the Slingshot "look" better
& also,

I've been tryin' ta learn ta Cricut
...ta get these decals (stripes & vents) done a bit more professionally :thumbsup:

I scanned 'em
...& saved 'em on a flash drive, as a JPEG file :cheers2:

Now, I am workin' on/figurin' how ta gettin' 'em down loaded, into the Cricut Design Space App/thingy :unsure:

Well, I figured how to get artwork uploaded into the Design Space ;)
...but, adjusting & workin' with it, is gonna take some more learnin' :unsure:

Also, been thinkin' & workin' on the dash board a bit more :thumbsup:
...& workin' on getting it wired up.

It'll just have an On/Off switch
...a Reverse switch
...a PZEM-051 power meter PZEM-051 100A DC LCD Digital Panel Power Meter KWh Voltmeter Ammeter With Shunt | eBay
...& a small GPS speedometer Car Digital GPS Speedometer Odometer Head Up Display Overspeed Warning Alarm HUD | eBay

The power meter can be/is "powered" by up to 100V (this vehicle has a 48V system/~54V top charge)
...but, the speedometer can only be powered by ~5V (like from a USB port)

So to "power " the speedo, I got the bright idea to build a voltage divider (to reduce the 48V (pack voltage) down to 5V) :idea2:

I did some calculations & it looked like, if I used a 2,000 Ohm 2w resistor for (R1) & a 240 Ohm 2w resistor for (R2)
...the combination would reduce 48V down to ~5V

So, I assembled one then tested it with a MM
...& there was ~50V going in & 5V coming out
...but, when I connected the speedo it wouldn't/couldn't "power" it

So, I did some investigating, here are the specs
Specifications:
Model: C60S
Screen size: 3.0 inch
Product material: ABS+PC
Input voltage: DC 5V
Working temperature: -30~80°C
Input current: 50~120mA, can be powered by power banks (It has no built-in lithium battery and only saves the total mileage data when power is off, other data is not saved)
Satellite positioning speed: 1 to 3 minutes in open space; no satellite signal when indoor. (rainy days affect satellite positioning speed)


So, it looks like the input current is 50~120mA (.05A-.12A)
...& with the (2) 2W resistors that I used "in series" (I believe) the math would be (2W/48V = .04A)

Then, I tried using (2) of the 2,000 Ohm resistors & (2) of the 240 Ohm resistors (4W/48V = .08A)
...but, the speedo still wouldn't come on or "light up"

So then, I said, "what the :censored:" & tried a (4) 2K Ohm & (4) 240 Ohm set up
...& Boom! it came on or "fired up" :2guns:

But, I've noticed that the (4) 2K resistors warm up & get kinda hot
...even when NOT "in use" or "powering" the speedo (parasitic draw?)

I understand resistors sometimes "warm up" during use
...but, how warm or hot is "too hot"? :huh:SAM_3557.JPGSAM_3591.JPGSAM_3592.JPGSAM_3595.JPG

Well, if it works...it works ;)

Now, we just gotta deal with this gettin' warm/hot situation :cheers2:

Ima thinkin' ta put 'er "in a box"
...for it's own protection
...& for the protection of everything around it, too :thumbsup:

So, I disassembled & re-purposed (1) of the speed controllers that I "fried" while building the Lunar Rover kart

Its an aluminum box with a circuit board that slides into grooves & is kinda "suspended" up/in there

First, I cleared everything off of the circuit board
...& removed all of the wiring

After disassembly, I coated the circuit board with a generous layer of liquid electrical tape (ta create an electrical barrier & kinda seal 'er up)
...& then, used some more of the liquid tape ta "glue" the 48V to 5V voltage divider, down onto it :2guns:

Let 'er dry over night
...then, just "slid" 'er in
...& screwed the ends on :cool:

I also, "labeled" 'er so, everyone would know "what's up in there" :sifone:SAM_3641.JPGSAM_3642.JPG

Voltage dividers are very inefficient, hence why the resistors are getting so hot.
Switch mode buck converter? Probably not a big deal in the bigger picture, just a thought.
Or larger package / power handling resistors.
