G'day all,
Not all my intended programs will need a big VGA screen. Some might be better on a smaller, more portable screen like an iPad. I think I know the answer to the first question but:
1) can one connect the CMM2 VGA output to an iPad (all the www talks about is the other way round which of course is easy. I am not proposing running my PC just to mirror to the iToy but rather a direct connection from the CMM2 - all-be-it with some adapter and/or an App);
2) can shedders recommend say a 10" screen that takes VGA input (preferably from personal experience)?
3) any comments?

Cheers,

Andrew

I'm curious what others may say as I�ve been hoping to turn my CMM2 to an all-in-one or a laptop. Alas I don�t know enough about electronics to venture into this without some solid advice first.

I'm planning to get a second MicroMite Colour 2 once people have gotten their fills first (don't wanna be greedy, would like more devs and first adopters before we hog the rest)...

But then I will make a laptop with it, I'll design a Retro Looking "C-64" style laptop chassis for it as I have a monster sized 3D printer.

Planning to find some old laptop screens I can remove, those are often VGA compatible with the inverterboard and all, just need to solder a plug for it and find the pinouts and remove the driver IC.

I will keep the forum posted on this WHEN I get this far, ya betcha!

I have used a small standalone VGA monitor such as this one
with a Colour Maximite 1 and it works perfectly therefore should be no reason why it would not work with a CMM2.

Mine is a 7 inch but the 10 inch shown should also be OK (in fact, any that has a VGA input should work). If you wanted to, you could then pull the display and electronics out of its case and mount in a laptop style case.

Sending the VGA to a tablet or phone is an entirely different kettle of fish and I would guess without some fairly heavy duty conversion from the analogue VGA to a digital stream and then some casting app to get it to the tablet, it is not really a practical road to take.

Depending on your application, the ARMMite H7 using the ST32H743 could be a solution as it supports a whole range of smaller TFT displays built it.

Doug.

... almost all of the Maximites, the MicromMites, the MM Extremes, the ArmMites, the PicoMite and loving it!

Hi Andrew,

I bought something like this to play around with an old laptop's TFT screen I salvaged..

VGA-Laptop screen

Note! I Didn't not buy that model specifically or know if that one even works... It is the `concept'.

I will try to dig out my screen and the adapter and try to take some pictures and see how it runs on the CMM2.

Kind Regards

Mick

Hi Andrew, All,

Hey I found it and it works well. The yellow on the screen looks white but is actually beautiful colour as expected.

The board looks to be the identical one in my link also (that is always a plus)

I used a 15.6" screen I salvaged..

The beauty is the screen is so thin, it can be mounted on a wall or in a thin frame etc if you can get the bezel it even looks great but in my case the bezel was broken.

Kind Regards

Mick

I have a 7 inch LCD purchased for the CMM1 many years ago.

The display is sharp and steady but 800x600 is way too small for my eyes.
Other modes are fine and one day, I will get the touch working.
For the original, I did it by directly reading the x y resistances in basic but next time I will do it properly and use the touch IC.

There are plenty around that take VGA and HDMI as well as composite.

That Idea was briefly touch on in a thread I started about making a project to integrate a CMM2 into a keyboard making more retro feeling then some else suggested making a laptop Like the PITOP.

I'm using 8 inch LCD Orion TV with VGA input. Works like a charm.

I bought my 12 inch screen (in 4/3 for 800x600 res) in a store that sells used equipment for 10$
