that LCD will likely run on I2C, not SPI, and I2C is terribly slow. A lot of them offer SPI, so maybe see if it does? and potentially change it? or get an SPI screen? Theres plenty you could change in your code to make it more bad-ass, but i would start with changing the battery functions etc to accept a single colour argument, so in your code you can write drawBatt(RED) and drawBatt(BLACK). That way you a) save on code and b ) if you change the icon later, or move it, you only have to change it in one place and it will always cover itself back up and you get to learn a new thing (if you dont already know how to do function arguments )

This is going to be the single greatest "why the fuck would you do that!? And if you must, why didnt you do it the sensible way using xyz part?" project and im loving it p.s. solidworks had their lawyers send an email telling me to stop using their cracked software and pay them $12,200, so i might join you in learning fusion 360

none of your photos work... :unhappyface:

So PWM keeps torque the same, will just change the speed... What's the deal with it wanting to unwind? Is there a sprag clutch/ratchet clicky thing? How does it unwind? Does the motor go in reverse and unwind? What slows that down when there's a 1ton load on it? Or is it a worm drive it something that can't be back driven? A 100A speed controllers isn't the hardest thing to make, but getting someone to design one for you won't be cheap... Some numbers I would expect from an electronics firm would be 30 hours research and design, $1000 in parts for first prototype, 15 hours writing code. Then put it in a box and fill with epoxy. Guestimates parts cost for the 10 units would be ~$150 each, so looking at $6500+ to build 10 units? You'd also be looking at a 4 or 5 week lead time on that at least I could do it much cheaper from home as a home job, but not sure how I feel about building a motor controller for something that lifts a big heavy thing, and having no liability insurance etc for home jobs. Also, those are numbers I pulled out of my thumb... But would be what I'd have used back when I worked at ProTech doing that sorta shit... But I am notorious for under quoting haha What's the thing you found that's perfect?

because you can use the arduino to convert BCD to decimal (converts binary to decimal) and then send it to one of those HV5812 nixie tube drivers, which are daisy chain-able serial to parallel chips as well so can control as many nixie tubes as you like with 3 or 4 arduino pins

and i think you can also run that visual micro in atmel studio from what i've read? never tried... atmel studio is the proper way to program a micro, but you can compile arduino in there as well with the add on and is based on visual studio as well

Somewhere on the internet i saw exactly what you want... but cant find it this second, i'll keep trying. those LCDs run on SPI and i2c, just use it in SPI mode and then you can connect as many as you can find CS lines for. So they share the MOSI and SCK pins, and have a different CS pin for each LCD. MOSI is the data line, SCK the clock and CS the chip select, or slave select. You will likely run into RAM problems before you run out of pins as they often use a RAM buffer for the whole screen, and with a decent mumber of pixels (especially in colour) that could become memory hungry

so heres a video telling you exactly what to do (first youtube result) but see how slowly the display updates? Arduinos and 'big' screens just go slow. Updating a whole screen takes a long time, and you can noticibly see it draw the thing you wanna see. It's not terrible, but just be aware that it wont be like watching a noprmal screen pop up a symbol or anything. still, not a bad way to go, especially when you're only updating a small section of the screen at a time

So i thought i replied to this already, but never hit submit. Guessing its one of those I2C LCDs? pretty sure there will be some example code for them on the interwebs somewhere for the arduino IDE. Just keep cutting and pasting example code together until it does what you want There will be some graphics libraries that can display simple images like that i'm sure. I've only recently started playing with the arduino IDE because in the old days it was just garbage and didnt do anything for me, but recently got a few WeMos D1 modules, and was insanely surprised at how easy it is to get libraries installed and example projects loaded etc. It all seems to just work and you dont need to know anything about micro controllers at all to use it. It's amazing...

Damn it! i think i'm busy on the 28th, was planning on coming round Saturday, but i'll see how i'm placed that Sunday instead

You're welcome to message me if you need to tackle something you can't find online

Roman, you know the rules! No posts without graphs allowed...

Thats cool man!

I won't be coming on the cruise, I'll meet you lot when you get to the tron

sounds like a plan

Then your lift pump is just too small... Lift pump should still flow enough to keep the engine running, its just designed for flow, not pressure... but should still be spec'ed so it's big enough...

wonder if thats why my china 044 is loud as fuck... /nah, will just be because china

i drool over this project so much.... just wanted to say keep those updates coming!

im keen

burgers!

What!? Thats terrible... Wish we had caught the person...

totally thought this was going to be today... Did you tell the burgerfuel people? they told me off for not telling them we changed the dates a few times now without telling them, as they are still on the second to last Wednesday of the month plan (or 3rd Wednesday unless there are 5 Wednesdays, then its the 4th Wednesday as chris used to put it) No idea why they complained to me specifically, but they do :/

What a good day Cheers Neal, and everyone who attended!

You're are the best! We're at the place

Walters road is the ane that rubs between southgate and mill road. Go to south gate, and by the roundabout turn into Walters road. Go over the the tracks and keep going. Then a roundabout, keep going. Then there will be some fields and car parks etc
