Hackaday Prize Entry: Giving Phones Their Tactile Buttons Back

In the before-times, we could send text messages without looking at our phones. It was glorious, and something 90s Kids™ wish we could bring to our gigantic glowing rectangles stuck in our pocket. For his Hackaday Prize Entry, [Kyle] is bringing just a little bit of this sightless functionality back to the modern smartphone. He’s…

This Sensor Board is yet another variation of another one on my site. It is not for sale with no real purpose in mind but the design files to make your own are here. The project was created as design challenge. My full time job is pcb design work and as a hobby I enjoy experimenting with new design ideas.

This was one of the more challenging designs I’ve worked on in a while. A few times I’d given up on routing it. Evan using four routing layers I found it tough. The idea was to hide the bezel of the display behind the board but have sensor components on that same board. It would look something like a little tiny television with all the components around the edges.

This latest revision has fixed a few issues I found on previous versions but the design idea can possibly help others in some way. Full credit goes to Adafruit for publishing the Feather M0 design files along with the bootloader. I used the Feather design to create the schematic for my board.

Hackaday Prize Entry: PaperBack Desktop ePaper Monitor

When we announced the Hackaday Prize with its Best Product category, [PK] polled his wife and co-workers about the idea of making a desktop monitor using 6″ 800×600 ePaper, which he has since built and calls the PaperBack. One such requirement for a monitor is to be able to connect to it using one of…

Homemade 6 GHz Radar

The third version of [Henrik Forstén] 6 GHz frequency-modulated continuous wave (FMCW) radar is online and looks pretty awesome. A FMCW radar is a type of radar that works by transmitting a chirp which frequency changes linearly with time. Simple continuous wave (CW) radar devices without frequency modulation cannot determine target range because they lack…

Hackaday’s Open Hardware Summit Experience

 writes about 2017 Open Hardware Summit last week in Denver:

Hackaday’s Open Hardware Summit Experience

This yearly gathering brings together the people and businesses that hold Open Hardware as an ideal to encourage, grow, and live by. There was a night-before party, the summit itself which is a day full of talks, and this year a tour of a couple very familiar open hardware companies in the area.

I thought this year’s conference was quite delightful and am happy to share with you some of the highlights.

The OSH Park table was not only showing off a PCB panel as their signage, but had our favorite SMD solder challenge boards on hand.
