Re: github?

I am seriously, totally interested in any system that would help us organize information. Can you give me an overview of how github would work for us? In a version control system, you mostly want to dump text based files (certain cad drawings, plain text,...) , as opposed to binary files (photos, ....

github?

Hi all (especially Dan & Rob), Have you ever considered using github for diybookscanner.org? There's lots of information floating around the forum, but it's not always easy to retrieve, let alone to contribute to. Yes, a lot of it is binary, so the added value of having that in version control is li...

DIY kit in EU

Hah! This CNC routing work is finally paying off. Faster than paper and a jigsaw, and much cleaner. Drilling the back side bearing holes was faster than doing it on the router. Worked quite well. And another simplification: I'll be doing electronical triggering, so no mechanical trigger. Some pics: ...

Of course. It was CC licensed from the beginning. I'm a great proponent of CC licenses. And even if I weren't, it's a derivative from CC BY-SA licensed original work!

Re: Daniel's Work Thread: Toward a Hackerspace Scanner

I've tried to redo the depth sketch of the design files for the .9.20 hackerspace scanner build before sending things off to the cnc. I have looked closely at the .9.10 files, the assembly instructions, videos and more, but I am sure I have made some mistakes. EDIT: * UPDATED: fix missing brace dept...

dlsr camera wear

Just read up a little on camera wear. It seems most consumer level dslr cameras are rated at 100k photos before shutter and/or mirror die under normal circumstances. In a book scanning setup, the wear is said to be much less. I've read quotes online of people doing over a million, and with more expe...

Re: Cameras for the Hackerspace Scanner

Hi all! I though you might like the bit of research I've been doing on cameras and speed. Some options: * cheapest: direct import from China, refurbs, ... (you're on your own here) * very cheap: Canon PowerShot a800: +-50€, slow digic 3 processor, 10 mpx, chdk beta * cheap: Canon PowerShot a2200: +-...

Re: Glass

Anyone using a Canon 500d? How do you go around the non-cable power of the camera? I mean, I have to charge the battery a lot, and I don't seem to find power cord for it anywhere. Do you know if this camera can only work with battery? Rui, what you want is the Canon ACK-E5 AC Adapter. I've ordered ...
