I'm an IT guy with an Electrical Engineering degree. In the past 20 years I rarely used my original profession. So call me a restarter. :-)
MSP430 based Digital Frequency Counter (FC002). It has 16MHz maximum frequency input and calibrated to the GPS system. The project documentation can be find here: https://github.com/sufzoli/suf-electronics-fc002
This is a simple voltage reference based on the MAX6350 5V reference. It has calibration option battery good indicator. The project documentation can be find here: https://github.com/sufzoli/suf-electronics-vr001
This is a small battery powered LCD thermometer based on TI's MSP430 and an MCP9808 I2C digital sensor. The display is driven by a PCF8576 LCD driver. The project documentation can be find here: https://github.com/sufzoli/suf-electronics-tm001

Thank you for the skulls.
I'm a bit busy now with some computer projects as you can see (my desk today) :-)
I'll come back to you with some more drawing as soon as I can, in PM.
That is cool, I wish I had a desk like that. Wow, no kidding, you are busy :).
Happy to have your input any time. Thanks man.
@Roman It is just for today, maybe for a few more days. It came together: I'm between two jobs, so need to transfer data. My Mother got a new notebook - set it up. My wife inherited my previous notebook - setup, transfer data, I needed a new home router (the old not fast enough) - setup OpenWRT/OpenVPN, my lab PC waited for the install for months now - just added to the crowd. So nothing serious, just keeps me busy. :-)
Thank you for taking interest in my project. It is always nice to be supported by likeminded people. Thanks again.
Thanks for the follow! Nice stuff on Github, btw. :)
What do you mean on "Nice stuff"?
BTW do you speak Hungarian (just I guess on your name)?
>What do you mean on "Nice stuff"?
I was looking at your github and I liked e.g. https://github.com/sufzoli/suf-electronics-ps002.git. I was (planning) doing something similar for an audio (pre) amp powered by USB. And the pololu stepper kicad footprint! Just needed that :)
>BTW do you speak Hungarian (just I guess on your name)?
Igen :) but I am not that good at writing (sajnos) , grew up in the Netherlands. Speak fluently, though. And quiet often visit Hungary.
Thanks for following and for the skull too! I'm very interested in your dc motor controller, I'll have to do something similar in the second part of my project. Good luck :)
Thank you,
I think, my dc controller is not really fits into the 3D printing, as the measurement technique, what I use there is good for keeping high speed motor at constant rotational speed, but clearly not good for closed loop servo, with accurate positioning, what you need I guess.
On the other side, may I recommend one of my other projects to you?

This one is advanced since I wrote it - updates coming soon
The MOSFET controlling I use there is much better, then the one the RAMPS board has, what you intend to use at your initial design (running cooler, keeping more current to drive the bed and the filament heater)

p.s: I'm thinking about to ask to join your project. :-)
Thank you for the follow on my 5 Axis Mill! I really, really appreciate your interest!
Just noticed your blog post about the Aoyue pcb holder, I have one of those too, it is a piece of junk! Hope you like your Stickvise, thanks for mentioning them on your blog, just noticed it.
Thanks, anyway, we will see, and definitely write my experiences.
Thanks for following the Muffsy Hifi Dual Power Supply. :)
Hi SUF, thank you for your ideas. It really helps to think out the box. I am considering making changes to the way I make current and voltage measurements based on our discussions.
