I am currently developing my own AVR development, arduino like. I want to make it a industrially made PCB, and I want it I am certainly not the first one doing this (or even in the first thousand), and some would probably say "Niels, this is a totally pointless exercise, why don't you go to something else"
And maybe it is, but who are they to tell me what to do? I have some issues with the arduino in its standard configuration, where the most irritating of these are the downright stupid design decision of a pinspacing incompatible with a standard perforated protoboard. And they are expensive, unless you go with an imported clone.
But I go the idea in this episode of the EEVBlog, where Dave agrees with a viewer, that building a kit is a good learning experience. Mind you, he is probably talking somehting more advanced than yet another Arduino clone, but this has the added advantage of giving me a piece of experimenting equipment that I need.
- DIY friendly
- Programmable from the Arduino IDE
- As cheap as possible.
In the next couple of weeks, I will go through the process of designing the Eigthtuino.
I am currently at my second prototype, which, confusingly, is called the eightuino, rev1. It will take some time before the blog series will reach this far, but here is a spoiler (yes, I now, it is a bit wonky in the construction, that is what you get when you solder with a hangover):
