Hey my original mpguino had a yellow backlight, the new one I bought a month ago has a green backlight. You guys change that up when you changed how the backlight was driven? Something about using less power and getting less hot?

yup, two changes.

first one was a while ago, we switched from a pnp to an npn on transistor T1 and bypassed the regulator, less load on the regulator and easier to relocate the backlight resistor outside the case and/or drive it from the instrument panel dimmer. It also meant that any energy stored in the capacitors would only go to the cpu/display and not to the backlight if there was a power dip, a-la "protect the brain", and that should help stability.

second we went to the low power lcd, which has a greener look to it. The lower power meant the backlight resistor (R1 below) was changed to about 450 ohms from about 81 ohms, IIRC.

Hi


I already donated once, and got MPGuino. Can i donate again, and get another?.

Btw. Great device. distance, speed, consumption, is spot on!. had it for a year or so now.
Tho it has died on me two times, but just had to disconnect the power 1sec.

Are these still being shipped? Also, do they come in a project box for a clean finished look or is that something that we need to do? If so, does anyone have a link to a good project box for these things? Thanks.

The normal "small" project box at radioshack fits perfectly with just a few mods.

Good question.
I feel like I am gambling. We'll see how it pays out.
