Re: Prototyping services?

Thanks Gussy! Your post is very helpful. Unfortunately I am living in Ukraine right now and if I could find like-minded tinkerers, I probably wouldn't even be able to speak with them :( This is a device that I want for myself, and potentially a commercial product. I am going to post something on EL...

Re: Prototyping services?

Your question is actually a few in one. Having a design reviewed, prototyped and tested are very different things. For someone to review your design, you are really looking at contracting an engineer or a design house to build you something. I don't know of any places which will simply look over you...

Re: PCB Design Check

Nice work! I'm glad you redesigned the board, it looks much more symmetrical and professional now. A few things: All the vias seem to be 8mil. I wouldn't use the minimum drill unless you have to, especially on the power traces which I would bump up to 20mil or thereabouts. Signals are fine at 8mil s...

Re: selling open source products

Juat my two cents. You have to ask yourself: what I want to do with my product: make money or "give it to the community" ??? If you want to make money, don't make it open source, as it will be very fast copied and sold by chinese. :| But as a side effect, you should provide support, repair, etc... ...

Re: PCB Design Check

Hi nickersonm, First off, for someone who has not done a multilayer board or anything this dense before, this is a top effort, nice work. To answer some of your questions: The via clearance in the buses seems somewhat small - does it look ok? These are fine. I put the board through a 10mil clearance...

Re: Lines On Pcb Layer

This is just something that happens with printing in EAGLE, don't change anything in the design or gerbers as nothing is wrong.

Re: Longest Range outdoors

What you really want is some sort of mesh-network (aka Zigbee / Chibi / 802.15.4).

That way you can use other players to re-direct the communication through, if one looses signal with the base station. Or alternatively put up repeater stations around the place.

Re: Merging three different designs into a single Gerber files?

Look up gerbmerge.

Takes a while to get your head around it all, and I wouldn't bother trying to use it on a non-linux environment, but it's pretty nice once you get it working. I use it all the time for production panels.

Re: EaglePCB: Some questions regarding design

That is correct, but a few small points.

- You have an airwire on the bottom layer at the top pad of the resistor. You should really complete the connection.
- You should also make your vias round and of a smaller drill size, something like 15-20mil

Re: Gold Phoenix order question

Before you submit your design, make sure to create a border of your board in the silkscreen layer. This is a requirement that Shane has to make sure they route the board properly. I've never had them require this. I use Protel, and normally put the board outline on the "Keepout" layer. I include a ...

I used an SVN repository for things like parts, design rules, scripts etc in EAGLE. Works great across many laptops/desktops.

Hopefully we get ReCaptha for registrations as well. That might at least keep some of the automated spam out.
