Artur introduces the MotoArt Instrument Cluster Controller shield for the Arduino Due, we hope this can serve as a universal controller for OEM gauges in "classic" vehicles like mine (and I use that term loosely, aka old, rat rods, lol)

Looking forward to more info on this!

Looking forward to more info on this!

Wonderful, thank you for your interest, we are editing a full length video and hope to have it up soon, in the meantime here is the final short teaser clip on the extra features and additional things this shield can do

[Gregski]

custom shield for the Arduino Due to run your OEM(ish) gauges in an EV Conversion just dropped

more info will be provided on arturk's GitHub soon:

So I bought this truck back in 2017 as a Mom & Son project to force myself to spend more time with my newly retired mother. [that's a big lie] the truck was a total POS and her house was closer to the seller's place than my house, so I two wheel UHAUL car trailered it there instead ! but it's the thought that counts

we did wrench on it together and took a ton of pics which then I lost when my SSD failed literally as I was backing stuff up to the Google

Destination: Mom's House, where it all begin
Distance: 13 miles
Terrain: Streets (no freeway)

and here she is back where it all begin: (yup took mum around the block in this one, like I have done in all my prior builds)

have fun with all your projects you all, be silly with it, enjoy it !!!

POST EV CONVERSION VEHICLE WEIGHT
* with only one of three 180 lb battery packs

here she is lighter than an albino color blind flea with an eating disorder, minus the door glass

Front: 1,880 lbs
Rear: 1,280 lbs

TOTAL: 3,160 lbs

TOP SPEED TEST #2
Still Powered by MG2 Only

88.9 MPH


Explanations Not Excuses:

• I don't have BMS so I am only charging to 90% capacity

• I have to drive out to the test site and that depletes my battery a bit already

• No windows in my doors yet, and I can feel the gushes of wind

• 3.73 stock rear differential gears, and I know nothing about differential gears

The Greg breaks his silence on his Intellitronix gauge cluster:

Lifetime Warranty, we shall see about that, ha ha

two tachs, two speedos, one volt gauge and one oil pressure gauge of for warranty repairs

EV Charging Lessons Learned

Stay away from long extensions cords.

So drove Black Sunshine to my mates house and he offered me the world's longest extension cord so that I could charge, and this is what we saw on the Charge-O-Meter 3000

we was pulling 14 amps on a 15 amp circuit at only 90 volts, no bueno

and this is after we replaced it with a 20 footer

just showing that I do drive the truck daily, and love it beyond words, anyway a question for you all, and this is embarrassing cause I'm an IT Guy by day and a Forum Updater by night, yet I don't use technology for technologies sake, if you follow that logic, well my wife does this thing where she deposits paper checks into the bank on her phone and I just don't get that Wicket Witchcraft, do you do it also like that?

I think that's more to do with being a silly auld fart than your IT background.
Unless maybe being in IT you have seen tech go wrong in so many ways you don't trust anything anymore.

I know for me both apply.

I remember the first time I saw a fax machine as a teenager I was fascinated wondering how they got the paper to go down a telephone line.

I am literally crying laffin' at that, made me think of lil me peaking around the back of a television set to see the boobies when a lady turned her back to the camera to get undressed, but no way would I admit that in public.

GOALS FOR THIS MONTH

Figure out how to charge at a Public Charging Station, using one of these, or try all of these [do you wanna see a shootout ?]

• should I DIY and roll my own EVSE thingie

• will I find that EV WEST is best!

• maybe I shouldn't act like a pimp and try the Simp... Charge Controller (what? it's the only thing that rhymed)

• do I Thunderstruck it

• or do I EVTV Motor Verk it ?

... all and more coming this month to the Good Enuff Chevy Volt 1st Gen Charger (which has been a complete work [ahem] little pony thus far)

Well, if you are using DUE chip then you only need to prepare interface in relation with PP and Cp signals
Process steps:
1. EVSE will sense PP connected and by resistance determine cable strength (PP resistor)
2. ms later when cable is fully inserted EVSE will start 12V PWM signal at 1kHz with variable duty.
3. On the charger side a circuit will sense 2K7 resistor as 9V and apply additional 1K3 resistor via relay or transistor.
This will show 6V to charger control and command "start charging". PWM duty will command charger(car) max available amps
4. If you remove either Cp or PP current must stop flowing. This is why i use PP pin to eneble charging process. Because it is the first pin to become disconnected if i pull cable out.

This is what i prepared in the bad old days when i couldnt use OEM chargers

Here is Openevse in line with what we are doing here...
https://www.openevse.com/

Or you can just buy a cable EVSE and then keep it installed in your driveway
https://www.aliexpress.com/item/1005005 ... 07655351_1

Or you can buy a cable and handle and put tha EVSE circuit into the handle. You can get parts here... but i dont know about shipping to US.

I made some example DIY here:

... so after 1 month of driving my newly converted truck to electric it's time to share what I have learned so far

[Gregski]

so let's start off with a little background, I am still using the older hardware sometimes referred to as Ver 2, basically the predecessor to the ZombieVerter, and don't get me wrong I like it, I mean I love it. However I found myself battling over do I try and make it do everything, ie one black box solution, or do I use multiple task specific boards/controllers instead

What I quickly learned while attempting to have the VCU display information to my little 2.4" Nextion display is that the VCU can't keep up, nor should it have to, it's friggen busy controlling your car, ha ha. Without geeking out too much the code that runs on it has better things to do and it needs to do them super fast, for example every 10 milliseconds [that's programmer talk for: "100 times a second"] that's friggen fast, and here I am trying to interrupt that process just to see what amps I am pulling as I drive to Starbucks

There are also hardware limitations, the VCU only has one PWM connector/pin. This is used to manage the speed of the Lexus transmission electric oil pump speed, as it should be, after all it is a Lexus GS450h VCU not a Do Everything VCU, so it can't also manage the Tesla water pump

So somethings it can't do, due to software or processing and others it can't do due to hardware limitations, but guess what it can do charging. It can do charging because charging is mutually exclusive from driving, in other words you don't charge when you drive, and you don't drive when you charge. But should it do the charging and can it do EVSE charging / charging at Public Stations? I don't know, this battle continues to take place in my noggin, but that's ok now that things are working this is a good problem to have.

and so this is where we are at, I have a working VCU that controls my vehicle when I drive, and it controls my 1st gen Chevy Volt charger when I [ahem] don't drive, ha ha

[arber333]

Ok you are correct vcu shouldnt operate driving functions when charging. That should save some bandwith.

You may also try using watchdog in case VCU gets overloaded often...
