Surprise Picture CardView Instructable »
Very nice Instructable with lots of good resources! One you left out is one of my favorites: FreeCAD (https://www.freecadweb.org/ ). Has a nice gear generator built in and can be used to create the rest of your machine's design as well.
I assume by your question that you are just starting out. (If not, I apologize.) So I would suggest the Arduino Uno R3. You might consider an experimenter's kit along with it. Google for these. Adafruit is a great source.
Yup. Ya gotta have something to start with. Maybe you can borrow one from a friend? This 'ible is most useful for someone who has an arduino, has developed some apps, and doesn't want to spend the price of an arduino to build a stand-alone version of an app.Could also work for a group that wants all the members to have a cheap arduino to experiment with.
I don't use repetier so I can't really help you. Maybe try the RepRap site?
Great 'Ible! I have one question: In Step 8 you say, "Reasons for the deviations will be explained in Step 9."I've read Step 9 closely and don't see any reasons. What am I missing?Thanks.
Thanks for your interest! Please try the latest version (it's 1.6.12 now, I think) and see if it works. I haven't tried using earlier versions, so I can't help you there.
Great question! To make a truly tiny one-chip Arduino, the tqfp is the way to go. However, the software side should be the same and this Instructable should guide you. But, of course, the hardware side is a different matter. You need to figure out how to get access to the necessary pins so the part can be programmed. Typically, the 6-pin programming header is used for this purpose. Then you need to decide how many I/O pins you want to have access to for your target project or projects. Lots of details to think through, but it's a great learning experience. Go for it!
Thanks for your interest in this project! Let's see if I can help you.Note that the ATTINY85 has the same USI as the ATTINY2313, so the code should work with it. What problems are you having and what have you tried?Note that there is now support for the ATTINY85 in Arduino. That might be a simple way to get things going and experiment. Have a look here:http://highlowtech.org/?p=1695HTH!
Thanks for your interest in 328/Duino. Note that you can get 328P chips from the same Chinese sources for a bit less than the Pro Mini. The Pro Mini is nearly twice as wide as the 328P, so might be large for some projects. But as you say, we're rapidly losing our hardware skills to the Chinese. I personally like to be close to the hardware I use and know its strengths and weaknesses. I hope there are others like me. That's who this Instructable is for, after all.
Should say "just as detailed in the figure for Step 3." Sorry.
Thanks for your interest in 328/Duino! Did you follow the instructions in Step 3 of this Instructable? When I follow those instructions and check the Tools -> Board drop down, I find the ATMEGA328... just as detailed above.
