I've had success with these parts: Fuse holder http://www.digikey.com/product-detail/en/178.6152.0001/F5194-ND/2515821 Fuse http://www.digikey.com/product-detail/en/166.7000.5302/F5168-ND/2515905 Most automotive fuses you find will be rated for 32 volts. When the fuse blows, there could be...

I used the tutorial found here: http://adamfeuer.com/notes/2013/08/06/building-an-orone-mini-part-2-solder-paste-stencils-using-gerber2graphtec/ I used the settings below with two passes, and a blade setting of 2: --speed 1,1 --force 8,15 The reason it is so precise is because the script...

I shrunk the cream layer by 2 mil, so the openings are slightly smaller than the pads.

Thanks! I finished the solder stencil and I think it turned out well: I used a Silhouette Portrait craft cutter, which I got for $80 on Craigslist, and a custom script I found online - it converts paste gerbers to special cut files. All you need is a few mylar overhead transparencies ($20...

Hey everyone, Just got the PCBs back from OSH Park and they look great. Here are some pictures: http://imgur.com/a/TdqGv#6KqZs40 Tonight I will be ordering the parts I need and trying to make a solder stencil. Wish me luck!

I haven't gotten the boards back yet - they estimated that they will be shipped September 15th. I haven't placed the balance resistors - they wouldn't fit on the Uno board, but it's a possibility for the future Mega board. In the meantime, I have ordered some equipment to build these, and I'm...

Posted an update on the first page. Just submitted the prototype board to Osh Park, and they might be built on September 5. Here is a preview: http://imgur.com/a/GaafQ#BHyFR0V

Hey all, Posted an update on the front page, and reorganized the information in the first post. The PCB should be done pretty soon. I am trying to gauge interest in the board, so let me know in the comments or via PM if you will want one when they're finished.

Update for 8/20: Spent the last week routing the new board, the traces are a lot tighter with the new components and smaller board size. The board is about 90% routed, so I still think this will be possible. I am moving the EPROM programming functions to a separate small board so I can...

Just posted an update on the first page. Some of the features that might have to be left off: - You can choose the CS pin used on the board (for example, set it to pin 6, 7, or 8) - Ability to leave board plugged into batteries while not in use I am actively looking for feature suggestions...

Hi everyone, I just want to point out that I am still working on my own board utilizing the BQ76PL536A and this thread is to discuss this board. I am not collaborating on hardware with dmwahl and mwkeefer, because I have a slightly different vision for my board, but we have shared software. I...

Glad to see progress has been made in your project. Unfortunately progress on my end will be slow because I'm moving within a month and starting a new job. I don't have the ability to work on hardware right now, but if anyone needs coding advice just let me know. I posted my code in dmwahls...

The chip select pin I assigned on board was being used for the USB host chip to communicate with Android. I recruited that signal to a different pin with sky wires and it worked fine. I would just double check whether there are any signals assigned in the Arduino Uno already.

If anyone wants to take a look, I attached a program that includes a few useful functions. I can edit it a bit later, but it has the basics, including the CRC check that you need to write bytes to registers on the BQ76PL536A...

Hey all, I am working on a similar project, except for the Arduino Mega board. I produced boards and code that work. If you have any questions about code, I have a working implementation that I can share. I haven't converted it to a library, but that might be a good next step.
