A new open source hardware project every month
You are currently browsing articles tagged PCBs.
We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few professionally-made PCBs from one of our past or future projects, or a related prototype.
This is a USB controlled RGB color changing light. Someone made some minor modifications to the design and had a bunch of boards produced, we ended up with a pile of the extras. We’re giving away two PCBs this week, just ask for one in the comments.

This week we’re giving away two Bus Pirate v3b PCBs. v3b is a minor update to the Bus Pirate with a few tweaks that make it easier to manufacture, read all about it here.
You can get a Bus Pirate for $30, including worldwide shipping at Seeed Studio. Adafruit also has the Bus Pirate and probe cables in stock and ready to ship.

coolnicks posted this picture of the assembled web platform hardware from Seeed. Our prototype was on plain green PCB, so this is the first time we’ve seen it in danger red. Thanks for the pics!
If you’ve just received your web platform, here’s some tutorials and links to get you started:
You can buy an assembled web platform for $40, including worldwide shipping. Seeed isn’t currently shipping due to the Chinese spring holiday, but your order will ship ASAP after they return on February 22.

Charlie made his own Bus Pirate PCB and used LPKF EasyContac rivets (warning, page denies non-US IPs) to connect the front and back sides. He had to enlarge the vias to 31mils to fit the rivets, and suggests going even bigger if possible. There’s more discussion on Charlie’s blog and at CNC Zone.
The LPKF ProtoMat PCB mill is also worth a look (this page accepts all visitors). That would be great in our lab!

s3c posted this home-etched Bus Pirate v3 PCB in the forum. Nice work!
Do you etch your own PCBs? We send double-sided PCBs to the board house, but still etch simple single-sided designs. Bus Pirate v0, va, and v1 were all etched on the stove in Ian’s kitchen.
If you don’t want to etch your own Bus Pirate PCB, you can buy an assembled Bus Pirate at Seeed Studio for $30, including worldwide shipping. Purchases at Seeed Studio support further development of this open source hardware.

We sent a bunch of PCBs to Seeed Studio’s Fusion service this week. The open source logic analyzer prototype was the most anticipated board, you can get the final hardware for free if you suggest the name.
The final design candidates for the PIC high voltage programming adapter went to the board house too. Looking at the circuit board, can you tell why we chose an MC34063A boost regulator instead of the microcontroller driven switched-mode power supply in our earlier tests?

This week we’re giving away free PCBs for our powerful new embedded web platform. We’ll give away a few now, and more in a second post later today.
The Web Platform is available as a kit for $35, including worldwide shipping. Seeed Studio will assemble yours for $5 more.
Seeed Studio has v2 Twitter Watcher #twatch PCBs for $6, be sure to get the right ethernet jack ($1.90). These are the extra boards from our Fusion PCB service order (formerly propaganda PCB service).
Assembled versions of our Twitter ticking, ethernet LCD backpack are also available for immediate shipment. A #twatch with LCD is $45, an assembled #twatch PCB is $30, prices include worldwide shipping.

This week we’re giving away two Bus Pirate v2a PCBs, PCB by Seeed Studio. The Bus Pirate v2a was really handy for developing the Bus Pirate v2 series, but the Bus Pirate v2go is really the final revision of the v2 design. The nicest feature of v2a is the power switch, which allows developers to reset the Bus Pirate without messing with the USB cable.
We’re giving away two PCBs this week, just ask for one in the comments. Be sure to use a real e-mail in the address field so we can contact you for shipping info. Some rules after the break.
Don’t forget that today is the last day to rant for free Bus Pirate v3 preview PCBs, check out this post.
