We are excited to see this LED-studded flexible Möbius strip by Chris Miller on Hackaday.io. The hardware design and firmware are available on GitHub. The project is using our 2 Layer Flex PCB service.
Want free flexible circuit boards? Well this is your chance!
Enter your design idea by TOMORROW into the Flexible PCB Concept Contest on Hackaday.io!
We are very excited about the Flexible PCB Concept Contest on Hackaday:
Have you ever wanted to try using a flexible PCB in your project but just haven’t gotten around to it?
Well this is your chance!

You don’t have to build something to win. Show us what you want to design.
Exciting times for people in Chicago that like hardware!
Tonight, Thursday, April 25th is Hardware Happy Hour (3H) Chicago at Ballast Point! It’s an informal hardware show ‘n tell that is a lot of fun:
And KiCon 2019 begins tomorrow! Come learn more about designing circuit boards with KiCad.
Look for our Drew Fustini (@pdp7) in purple at all the above events!
We are excited to see what people create in this new flexible PCB design contest on Hackaday.io:
The now-humble PCB was revolutionary when it came along, and the whole ecosystem that evolved around it has been a game changer in electronic design. But the PCB is just so… flat. Planar. Two-dimensional. As useful as it is, it gets a little dull sometimes.
Here’s your chance to break out of Flatland and explore the third dimension of circuit design with our brand new Flexible PCB Contest.
We’ve teamed up with Digi-Key for this contest. Digi-Key’s generous sponsorship means 60 contest winners will receive free fabrication of three copies of their flexible PCB design, manufactured through the expertise of OSH Park. So now you can get your flex on with wearables, sensors, or whatever else you can think of that needs a flexible PCB.
HOW TO ENTER
Go over to Hackaday.io and create a project with images of your flexible circuit board design, and be sure to tell the story of how and why you came up with it. When the project is published, look for the “Submit project to…” link in the left sidebar and submit it to the Flexible PCB contest.
- 60 contest winners will receive an OSH Park code for 3 complimentary boards from OSH Park shipped to them (there’s a size limitation detailed below). Please allow 8 weeks after the close of this contest.
- 3 Tindie gift certificates of $100 each will be awarded for:
- Best Project
- Best Social Media Picture or Video
- You can post a picture or video of your device, of you working on your device, or anything related on Twitter, Facebook, Instagram, Youtube, or any other social platform. You must post a link to the video in the comments on this page.
- Best Documentation
Here’s the small print on those free flexible PCB awards: If you’re one of the lucky 60 (yay, that’s a lot!) winners, you’ll receive a coupon that will cover the cost of a PCB up to 2 square inches (13 square centimeters) in size. If your design is larger you can still use this coupon and choose to pay the portion of the cost beyond that size. The best part is that OSH Park delivers three copies of the board from each order! See the contest page for complete rules.
WHAT SHOULD I BUILD?
Pretty much anything that needs a flexible PCB qualifies. Use your imagination! Folding cell phones are all the rage now, so use that for inspiration. Perhaps you’re into wearables, which are begging to be made from flexible materials. Repair a wonky laptop display with a new flexible connector? That counts. Working on something so small that a traditional PCB is just too bulky? We want to hear about it.
We’ve lined up some resources to help you get started. Check out OSH Park’s Flex PCB FAQ for all the technical details on flexible PCBs. If you’re new to PCB design, Brian Benchoff’s excellent Creating a PCB in Everything series covers everything you need to know.
Still stuck? Here are a few recent projects featuring flexible PCBs that might get the creative juices flowing (not all of which would necessarily fit the qualifications):
Now Tim’s onto the next big thing. He’s adaped the Tomu form factor to an FPGA board called Fomu with an active crowd funding campaign right now. The board will ship with a RISC-V core already loaded that can be programmed using DFU (or possibly mass storage). This is a popular move right now since a lot of people want to play with RISC-V or FPGA and here’s a way to do both without actually having to haul around extra equipment with you.
Some might think: what can you do with an FPGA where it’s kind of hard to connect external circuits? You could practice adding peripherals to RISC-V and other cores, but maybe what you should be thinking is: what could I do with my laptop if I had some dedicated parallel processing available? The board carries a Lattice iCE40UP5K, 1 MB of flash, 128 kB of RAM, runs at 48 MHz, and is compatible with the open source IceStorm toolchain.
If there’s one thing that will bring down the yield of your PCB assembly, it’s your solder paste. Put too much on, and you’ll get bridged leads. If you don’t put enough on, that pad might not make good contact. [ScalarElectric] has an amazing trick that’s sure to astonish and astound. Just use wedges and you’ll get better yield with fine-pitched components.
The trick here is to define the cream/solder paste layer of each package as a wedge on each pad instead of the usual rectangle. This gives a few benefits, the largest being the increased gap between paste shapes. You’re also getting a reduction in the total amount of paste applied, and a subsequent improvement in yield. (Reportedly, we’d love to see some data on this.)
