How can I make my own arduino from parts?

What would you expect as answers to this? List of parts? Soldering techniques? How to put it together? This is covered in detail on the official Arduino blog, IIRC. – AsheeshR Sep 20 '13 at 11:10

Ways to cut costs on arduinos. There is a blog post here: spuder.wordpress.com/2010/05/11/…, any other tips or links for making a low cost arduino such as the RBBB Arduino kit moderndevice.com/product/rbbb-kit, there is also the nerd kits nerdkits.com – spuder Sep 20 '13 at 15:43

<comments removed> Please do not use comments to answer these questions. This proposal is not part of a Q&A site, and the task at hand is to help define what is on and off topic for a site. Comments are here to help improve the questions; not to answer them. See What is the rationale for deleting answers? Thank you. – Robert Cartaino Sep 23 '13 at 18:23

closed as not a real question by Robert Cartaino Sep 27 '13 at 14:35

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.

Stated as general as this, this is a question one would expect on StackOverflow, but not here. – FvD Sep 8 '13 at 16:20
Well, this question is meant to be Arduino-specific, debugging on Arduino is basically debugging a software/hardware system. But I agree my question is way too general as stated. – Chris O Sep 8 '13 at 18:49
