So impressive, great work.

#92> I replaced the functionality of the black knob. To be honest I don't even know what its purpose was.
Exposure compensation dial.

#93Pretty neat. Crazy it uses an adhoc wifi network to communicate between the camera and the cartridge. Seems overkill for a battery powered device when they are already plugged in to each other physically.
It does seem like USB could handle the charging and data transfer with some kind of custom connection to make docking and undocking easy.
"Some kind of custom connection" is the real issue here.

#94Very cool. If you can make that cartridge dirt cheap, you will have invented an exciting new technology. Build a V2 with cheaper tech, change your wording a bit as to what the device does, keep the polaroid link a little bit, but make it your own and then I think you'll have something that could kick ass on Kickstarter.

Step 1: Have the idea.
Step 2: Implementation.
We're already half way there!

#95Hah, not exactly what most people think when you use the word 'print' but then again ... People have asked what is the impact of 'free' CPUs. Something Dave Rosenthal realized way back in the 90's was that the electronics for driving a display could be printed on the margins of the display and eliminate the need for a separate controller board. Having watched the evolution of displays and seeing Mary Lou Jepsen's wor…
I've long imagined something like that: a card-sized (including thickness) full-color display devoted to displaying, say, an entire movie. Given ultra-thin displays like OLED, dirt cheap storage, and "free" dedicated processing, you could hand out videos like sales brochures or cheap paperbacks. Amazing how technology has advanced.
Yeah except that would create massive amounts of electronics litter..

PixelQi! Are they finally going to put out a product anytime soon, do you know? Their low-power daylight-friendly monitors are only available on eBay as far as I've found.
Does anyone know if there any other initiatives beside PixelQi and e-ink displays for producing (modern) displays that can be used with passive light?
It would be fantastic to be able to bring my laptop into the sunlight for work. And with the expectation of greatly improved battery life.

Hmm, why isn't this in use.

#97This is one of those projects that at first, is easy to dismiss as "silly" or "useless". On the surface, sure. But looking at the imgur album and reading the comments (and I would imagine going to the website, etc - which I haven't done), it becomes clear (and the author even says so on the album) that this project ultimately served a larger purpose:
From start to finish, this project has helped the person develop a complete (or nearly so) set of manufacturing skills. An idea was taken from concept, on through a multitude of other steps (design, prototyping, software development, hardware development, etc), to producing a final working "product".
Now - it seems from the comments in the album that this isn't the authors first go at such a project, but it may have been one of the most complex or largest they have done. Regardless of that, it has helped them to hone and develop a complete set of skills very few people have.
Heck - I would encourage the author to try turning this project, or something similar, into a MOOC in some manner; I don't know if this is possible, or if it has been done before, but I bet there's a growing audience of people who'd love an all-in-one course to study to gain such skills. Part of the problem of implementing such a thing as a MOOC is whether a person has access to the needed tools and equipment; maybe that could be part of any pre-req's? Or, maybe people would pay for such a course, and parts or tools could be provided (kinda like those "boxed recipe meals" you can get)?
Ultimately, I liked seeing this project; even though to me it seemed "frivolous", it really is a physical form of "random play coding exercises" software engineers do from time to time, in order to learn a new language or framework, or just to try out ideas or whatnot. Such a project thus becomes a education and learning opportunity of a very intense sort.
If this individual hasn't gotten any job offers or such, I would seriously question "why not?" - they have shown a level of competence and follow through rarely seen in a single individual, and they should be considered a valuable asset to a company (that, or this person needs to create a startup or something).

#98This is pretty cool!
I noticed the author decided to use metric thread machine hardware. He's probably an American because he specified McMaster-Carr as a source.
#4 and #6 machine screws are a lot less costly here and available everywhere. (Your hard drive screws are 6-32, same as the electrical wall boxes; floppy 4-40)
I personally hate unified threads, on the basis that the rest of the world uses iso threads. But this is one of those times that being a pedant about it would increase the cost.

#99Great trick with laser cutter and black paint on the pcb. I wonder how end resolution compares to milled pcb. Also this is one of problems I have with Imgur. How to archive such detailed imgur post? I have tried ripme [1](great for grabbing image sets without addnotations), printscreen browser extensions (mixed results - most do not cope with floating menus and have problems with dynamic image loading), page saving o…
> Great trick with laser cutter and black paint on the pcb. I wonder how end resolution compares to milled pcb. Eh, I thought this was a point where they made the wrong call. You can get a much better result for less money and less personal time invested - just wait a week or two - by sending your Gerbers off to be manufactured. PCB manufacture is dirt cheap and has extreme quality compared to home-etching your board…
In home shop it all comes to what is easiest. Most boards that I do are single runs. If laser cutter can do single run on site without hassle of getting toner transfer or uv run that's great.
I did not see that this is different from single run operation (considering how it is wired) so no point to wait for pcbs. That can wait for tens or more pcbs.
Also it boils down to personal need. This is hand crafted and tailored piece. With this setup you can easily modify and correct everything to work.

#100Earlier quoted context omitted.

"Some kind of custom connection" is the real issue here.
I'm imagining a row of pins along the back or bottom of the cartridge, or an edge connector, like in the old Nintendo cartridges.
