Oshpark Projects

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

How is your soldering on small parts?

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.

Hi Rufus, the OSH Park Project - 7135 is OK and tested. The hybrid(DD) version may need a re-design. Can be used as is if only using 4x7135, 8x7135(stacked) or any from 1 to nx 7135 that you can fit. Cheers!

Thanks Tivo, I’ll need a link to the board at Oshpark so it works like the others. I can’t access anything earlier than July 30, 2013 to create a link in the op. Do they dump older files? And would we need to save them somewhere to re-upload if necessary?

I think OSHPark doesn’t have a search feature on their shared projects.
Here’s the link: TZF082A LED Driver - AMC7135

Cheers! :beer:

Check to make sure this link works, should be a cart pre-loaded with the parts for the SRK FET board.

Genius idea! Rufus - this should be added to the OP I think.

EDIT: Links works too.

The big diode & inductor (must be used together), & big cap are optional. Depends on how low the low needs to be, and whether it needs to be dead silent or not. There's a range of inductors that will work also, 1.2uH gives a pretty big effect on dropping the low mode reeeeally low, but anything from .58 to 1.2uH can be used. The 1.2 is a good baseline choice that should work for 90% of folks.

Thanks tivo, done.

CC, that is an excellent idea and now in the op.

Awesome!

FET comes from the EBAY link (I already have 10)

Payday I will be ordering 3x FET SKR, 17mm, and more than likely the 15mm as well (need a link to the FET though)

I already have 10x Tiny13’s and control items (the diode, resistors, and cap)

But with that link, I know which ones to order if I need more of Tiny13 control components

I think I might also whip up 2x of the Texas Pyro 20mm Nanjg’s as well (I have 50 of those 3 leg diodes in his design)…might do a giveaway and find guys that have a good record of testing drivers and send them a few to test em out (I can build em but don’t have the setup to properly test and whatnot)

Wicked cool idea on the pre-populated cart…great job!

You want any of those 2502’s with your Tiny10’s? I should have 10 about when the boards arrive.

You talking to me? If so sure…would you like me to build you a TexasPyro 20mm and ship back to you for trade?

and/or can you test the 32*7135 build? I really don’t have any way to do a current test and/or a SRK with enough heatsinking to hold up to that kind of current…plus it seems you have a much better setup (I don’t really have one) to test/review boards or whatever

I have 2 of the V1 no tab SRK boards by Mattaus (will be getting 3x V1.1 asap [probably not this payday as I had to replace a ruptured water heater today :frowning: ], haven’t put em together (shouldn’t take but an hour or so) but still have 2/3 of 100 7135 strip I got from FT…

This should be a similar cart for the 17DD & 20DD boards: http://www.digikey.com/short/hqzd0

The Vishay 70N02 FETs are here: http://www.ebay.com/itm/271319198579

For those who want one-stop-shopping and/or single parts instead of the batch of 10pcs from ebay, this part from Digikey should be about the same: http://www.digikey.com/product-detail/en/AOD510/785-1481-1-ND/3603497 I have not personally used one so no guarantees, but the 'important' specs look right. TO-252/DPAK, 3.2mOhms, 21nC gate charge, low gate threshold voltage, etc.

I just noticed the ebay listing, there was only 1 sold when I first found them, now it's up to 56. lol.

Wow, what happened to the price on the tiny13?? Last week I ordered 30 @ $0.54 each, and right now the same quantity of the exact same part in the same packaging is $0.99 each?! :O

Something change recently?
