Followup: picking an ARM chip
In my last post I talked a little about the process of picking an ARM microcontroller to start using. After doing some more research, I’ve decided for now to start using the STM32 line of chips. I don’t really know how it stands on the technical merits vs the other similar lines; the thing I’m…

Working on an ARM board
Pretty much all the electronics projects I’ve done so far have used AVR ATmega chips as the central microcontrollers. I’ve been meaning for a while to step-up into the world of ARM chips: it looks like you can get chips that are much more capable at just around the same price as an ATmega328P, but…

Rescuing a mis-programmed ATmega328
I had messed up one of my circuit boards, and in the debugging process I wanted to eliminate the external crystal as a problem (since there are so few other components in a bare AVR circuit). I looked at the ATmega328 manual, and found that it features an “Internal 128kHz RC Oscillator”, which sounded safe…

Dropbox Hackweek, part 2: building a simple robot
I’m late in writing this post since Hackweek was a few weeks ago now, but better late than never I suppose. As I mentioned in my previous hackweek post my goal was to use my new 3D-printer to build some parts for a simple robot. Unfortunately, getting the 3d-printer working took four out of the five…

Myduino: creating a low-cost arduino substitute
One issue I’ve quickly run into is that I want to embark on new projects, but don’t want to completely disassemble my existing projects in order to get the parts I need. For some parts of the project, like resistors and wire, it’s pretty easy to over-buy those and not need to scavenge old projects…

Microcontroller Project: Digital Faradmeter
Alright, I got my $10 soldering iron today and put together my USB->UART board, and I was finally able to program my Arduino-compatible ATmega328! You can see what I’m messing around with here: I got all the basic Arduino tutorials running, so I decided to try my hand at something a little tougher: a digital…
