PWM, DAC, and timers on the ATtiny

A few pointers on the subject of DACs, PWM, and timers, for future reference.

Last weekend I started doubting my setup miniMO. It’s been a while since I worked out the details, and wondered if I had chosen the timers correctly, so I went over everything again.

This is all the reviewed information, written down while it’s still fresh in my mind:More…

Mk2 Assembly Gallery

When I built the Mk2 version last December, I took pictures to document the process. This model is now obsolete, but I think the pictures are still interesting, not only because they show how I built it, but also because they make clear some of the reasons why I decided to change the design. Enjoy!More…

Breadboard Mk3 WIP

Today I started revising the breadboarded miniMO. I wanted to bring the printed model as much in line as possible with the PCB version, whilst emphasizing the different approach; my goals were to fit all the components of the latest design on the custom board, and to keep soldering to a minimum.

Repository up and running

It’s here!

With five new modules up and running, I’ve revised and uploaded the DCO code to Github. It has been a while since I last used Github, since I normally work with svn; I was pleasantly surprised that I can use tortoiseSVN with it.

Following steps: decide on the open-hardware license, figure out ways to distribute it, publish a video demoing the unit, start modeling the case, and start spreading the word a bit more.

miniMO multiplies

I received the PCBs last Friday and built a few MOs over the weekend. I’m very satisfied with how things turned out; the PCBs look sharp, I had no difficulties in soldering the components, and everything works correctly. I found I made a couple of errors with the design, but both have easy fixes and functionality isn’t compromised.More…

Takeoff

Hello and welcome to miniMO’s site! it’s pretty empty at the moment, but hopefully that will change as soon as I’m done dispatching the fear of the empty site.More…
