Yeah I need to improve my 'finishing'. Labeling, revision status etc. Because of the numerous versions of the same designs I got a little lost with where each was at and thats why we ended up with a few boards missing rear ground points.

You know what they say - practice makes perfect Smile

+1 on the 4 x aa battery carrier as per RBD. Serial and parallel. I could probably sketch something up with rough dimensions in DraftSight. Its the boards I would not know how to tackle.

There are too many layers in the EAGLE you are switching here and there. It is very possible you will omit somethings. After finished my layout design, I always transfer it to Gerber Files and then double check the layout layers by Viewplot ( Gerber Viewer ).

Check again… they have a free version that is limited to small-ish two layer boards and a single page schematic.

It is the same program file. If you do not purchase a license, it is a free version. Some restrictions will be released for the full version after you purchase a license.

Battery carriers? I can throw up a couple carriers.

4 x AA serial battery carrier – top plate. (masked vias)
4 x AA serial battery carrier – bottom plate. (masked vias)

4 x AA serial battery carrier – top plate. (exposed vias)
4 x AA serial battery carrier – bottom plate. (exposed vias)

I have not done a test order. I don’t really need a 4 x AA carrier myself.
12 awg wire should fit through the vias to connect the boards. Four around the edge and one in the center. The vias (on the topside of the top plate & bottom-side of the bottom plate) should then be covered in a thin layer of epoxy (kapton or packing tape even) just to prevent anything in the host from shorting top to bottom through the supports. Silkscreen is used for extra abrasion resistance in some places.

Masked vias look cleaner to me but those need to be soldered from the inside. Its soldermask + silkscreen. If in doubt, get exposed vias, easier to solder.

Again, untested. Only order one to try them out. Oshpark provides three copies anyway. $9.05 for three (34.2mm diameter). I could push the size down a bit to save a little on cost.

I don’t know if a simple 4xAA carrier deserves a thread. Let me know if you prefer it moved. Somewhere. Into the void. :ghost: Perhaps we could use an “Oshpark request / suggestion thread”?

Agreed, this should be the “production” listing of the project, the workups/revisions would be better in their own threads

MUCH less confusing

I think I was overly ambitious with my first eagle project and it stalled last fall. I’ll have to try again after tax time is done.

Eagle feels user-interface wise like a time travel in the early 90s (or worse ^^)
I’d give diptrace a go: http://www.diptrace.com/
It also has a free non-profit version (2 layers, 300 pins. you can request a 500pin version for non-profit hobbyist or academic use) and a big upgrade/ui overhaul is coming in the next months.

Thanks for drawing these carriers Helios, although the design would not have been as time-consuming as making a circuit board, it must have taken some effort to make them.

I think the pace at which ideas come up for Oshpark designs would justify such request/suggestion thread, perhaps you could start one, or Rdb or Mattaus?

Did you see Hikelite's carrier?  He may still have some left over, but if not, let's see if his design can join the list.

The low mode should be lower.

Good on ya, just keep it up. Another I have no idea what to do with it, but I just have to have it item. Very pretty.

Helios’ new 4 x AA boards now in op. How about a 2s2p version?

Will OSH cut those boards in square or round shape?

Ok, I’ll send him a pm to see if he can list it on Oshpark.

EDIT I pm’d him and he is still selling them so for the time being he is the place to get those triple carriers. The idea of this thread is to collect and index open sourced DIY projects that are listed on Oshpark not to pirate anyone else’s work and post it here. It’s bad karma.

I went ahead and listed Scaru’s board. I hope he doesn’t mind since it’s already shared.

Hikelite still has these boards for sale. I did enquire not long ago but I really want 4 x battery carriers.

Thanks, Warhawk and Dave_. Diptrace is nice I’ve been watching tutorials of both and I agree (Bare in mind that know 4/5ths of nothing) that the Diptrace is more user friendly. I like the proof reading function that checks for errors and un-connected leads and highlights them. I think I will experiment with Diptrace and see what I can learn. It looks like if you know what sensors, chips, resistors etc. as well as what pins you want to connect it will do the rest all you have to do is specify what size of copper poor and via’s you want it to use and then let it run. (Take that last statement with a very large grain of salt as I have less than 1 hour of experience and a lifetime of enthusiasm)

Eagle can do auto routing as well however from experience I can guarantee that you will want to manually trace the routs yourself. On boards such as LED drivers they don't get mind bogglingly complex so manual routing is easy to do. It also depends on how 'beautiful' you want your board to look. I can say this - automated routing will very rarely give you the best solution. You can also run design rule and routing checks in Eagle, do automated pours etc. I tried doing all that stuff at the start but the more I used Eagle the more I preferred the manual methods because of the control it gives you. It's almost as if I 'paint' the boards I make now. I do basic layout and routing and then 'free trace' every bit of copper. It's easier than it sounds.

Yeah, setting up the autorouter for the different trace sizes needed for power and signal traces etc. will take more time than routing such small projects by hand and will look way worse. Wink
I find little use for them at all as you can only trust them with really unimportant stuff. ^^

A plus factor for Eagle is the number of tutorials and videos out there.
Some claim the big part libraries are a plus, but they contain so many errors that one has to check pinouts and footprints anyway. To frustrating for my taste, I rather take the few minutes to make them myself then . . .
I think that for someone who hasn’t had any contact with any cad tools, eagle will be way more difficult to get used to than diptrace or other tools.
A new user should not need to battle an unintuitive user interface, the lerning curve is already steep enough. Wink
But that’s a question of personal taste in the end. Wink

I’d really like to see an OshPark tutorial. I’d like to order the parts and try it. However while Ordering a custom circuit board seems really cool, I am not really sure what to send them.

Which projects might be easier to start with?

Would like a single battery driver but don’t have to have that

If you use Eagle to layut your board, all you have to do is upload OSHPARK with your Eagle .BRD file and they do the rest… none of that tedious mucking around with gerber files…

Exporting gerbers is that tedious?
Oshpark has choked on some .brds. Gerbers get processed smoothly.

I have found that if it chokes on the first try, resetting and trying again usually runs it…that is if the .brd meets the “rules” requirement…

Yeah, you have to run the CAM processor, find and possibly rename a lot of files, zip them together, and upload the zip. Much easier to just upload the .BRD file.

When OSHARK barfs on an upload, it appears to be due to their server being busy (it runs Eagle to processor the .BRD or Gerber files) and a timeout watchdog kicks in. You then have to re-upload the file and try again. It can happen with .BRD and Gerber files…

Or use my CAM processor which produces 8 files. Zip all of them into one zip file and OSHPark will read them without any issues.

Please ignore my poor spelling.


EDIT: To use the above CAM processor put the downloaded file into the the 'cam' directory under your Eagle installation directory. In Eagle, click the CAM Processor button and then select File > Open > Job. The folder that opens should be the cam directory. Select 'Matt_Gerber_Generater.cam' and then once it's loaded, select the Eagle layers you want to include in each Gerber layer (or leave the defaults) and click 'Process Job'.

Please note that I don't use the dimension, tplace or bplace layers as I use the miulling layer to define the outline of my board, as well as tDocu and bDocu for ALL my silkscreen.
