I've run about 450 PCBs (maybe 15 designs) through Seeedstudio and used my own CAM job that's probably pretty similar to the Sparkfun CAM job. I've always checked the Gerbers in Viewmate and the drill holes align perfectly, and I've always sent those same files to Seeedstudio and had no problems with any PCBs. But I realize that I might be OCD and align everything to 0,0 when the design is finished.

I'm not being abusive, just doubtful that you're the professional you claim to be. Can you really be an Arduino mentor for someone's high school final project, when less than a week ago you said:

hey guys

i need some help

i am total n00b at electronics - i need help from 1337's like your selfs

honestly i did like 1 year in college and dropped out, thats my electronics knowledge

i can barely program (just enough to get by on arduino)

And only four days ago someone else asked for ideas for a school final project, and you responded:

Ah...that explains why I haven't seen that filter very often, professionals don't use it.

No one knows what crappity smacking is, and you're not coming off as a professional either.

They're looking in the wrong place, for sure.

Yes, the PIC10F2xx series in SOT23-6. Not only are they extremely tiny (almost fit within diameter of typical DIP solder pad), but they're actually available and have been for a long time. The ATtiny4 was announced like a year ago, and as far as I can tell has pretty much never been stocked at any distributor. The PIC10F series also uses the same ICSP interface as every other PIC chip, unlike Atmel introducing the TPI interface for the Tiny4, along with PDI for Xmega, plus ISP for everything else.

I put about 5,000 PIC10F202's to work for someone's art project during the Winter Olympics: http://www.tangibleinteraction.com/gallery/seed_truce


The low power performance of these things is amazing. I have some of those devices sitting on my shelf that are still blinking, 8 months later, off the original CR2032 battery.

I'd love to see a Microchip+AVR Arduino. DIP PIC18F for all through hole, or SOIC MCP2200 for a no-programming FTDI/8u2 replacement.

It's entirely possible to have a DIP USB-TTLserial solution. You can get USB PICs in DIP, and Microchip provides a a CDC implementation.

Totally possible if you're skilled at designing parts for injection molds and have a few tens of thousands of dollars lying around. Plastic parts are only cheap if you are making a really large number of them...on the order of the number of Arduinos ever produced, maybe.

A flipflop circuit is nice but will be plagued by contact bounce.

A switch could detect direction of motion by dragging a probe on the side of the drawer, closed only during drawer close. A simple cam could close and open another switch at the correct times.

Yes re: old computer consuming power. People talk about putting an old computer to work in your closet serving some minimal thing. "It's practically free!" But the type of old PC you find these days is costing you literally hundreds of dollars per year in power. If you actually want to save money then you need to find something relatively modern and low power to run your services. Thankfully, these days computer makers are actually addressing that market, instead of eking out the last cycle of performance. At the moment I'm bringing up a mini-ITX D510 Atom system that should run pretty much everything I need continuously and draw hopefully less than 40 watts. Don't have to worry about processing power for a long time and it's nowhere near as bulky or power hungry as, say, an old Athlon system.

If the cable connection I have now (8Mb/1Mb) was merely RELIABLE I'd be more than happy with it. Of course it's a little better now that I went out to the box and tightened all the connectors, but Comcast still likes to have outages after midnight.

If you're just talking about soldering the one or two boards, I'd do it for free for the cost of postage. I'm nowhere near the East Coast but Priority Mail is decently fast and cheap. Basically if you sent the parts to me Monday with $5 for postage I could have it back to you Friday-ish. (I just realized Monday is a government holiday, but still the turnaround will not be too bad.)

If you want to eventually learn to use gEDA for hobby use you can by all means. I'm just providing an opinion as someone who has been designing PCBs using Eagle for a number of years. Right now my rough count of PCBs of various designs produced and sold is about 25,000. Not exactly Sony but enough to have a pretty good idea what works when trying to get an electronics company off the ground. I learned Eagle using the free version years before actually starting a company, and then when I bought the pro version it paid for itself with the first design.

I did try gEDA, and Orcad, and PADS, and Pulsonix, and Autotrax, and Diptrace, and several others. Right now Eagle has the best balance of features and cost for me.

You cannot realistically start a business while being worried about a $1000 investment into a production tool that indisputably has value. Starting up the business we both had to put in $10,000 each that we didn't necessarily have to spare and could reasonably expect never to see again. Risk is always there. One time on another forum I saw someone ask if it was OK to make people pay for a kit product before he even produced and shipped them, afraid to invest any of his own money. That is the mindset destined to throw in the towel on a startup before it even has a chance.

I really don't want to point fingers because you have valid points on a philosophical perspective, and companies like EMSL do use gEDA, but by your own admission earlier in the thread you haven't even designed any PCBs yet. I highly recommend just trying a few packages, make the same design in each.

Even the pro versions of Eagle are pretty cheap, if you're already using it to make money. It pays for itself almost instantly. Worst case is that you have to keep using an old version of Eagle, or learn/buy a different package.

People think going open source means they aren't at the whim of a company's decisions. Yet I see open source packages getting abandoned more than commercial software. Isn't WinAVR dead at the moment?

Having the source to gEDA would mean nothing to me. I only have time to design PCBs, not write and maintain the software to design PCBs.

I'll be making the trek over to Queens for this, from California.

Actually, I live three or four miles away from the fairgrounds where they hold the SF Maker Faire. This will be the first Maker Faire I'll attend as a visitor instead of an exhibitor...looking forward to it!

I'm hoping a bunch of familiar names in the Maker and/or Arduino communities will gather for dinner in NYC.
