We have no idea if the background story is true or not, but we’re not going to let something like “truth” get in the way of a good story. The way [Kwan3217] tells it, first there were hours on sundials. Then when these were divided into sixty minute sections, they were called “minutes”. “Seconds” comes…
I thought of making the Benchoff nickel after I saw Brian’s Hackaday,io profile. He has a hi-res image of the center a Benchoff Buck which is well suited to being converted to a PCB. There is only a few colors and they have sharp edges. Bitmap2Component in Kicad, can easily detect these transitions and convert them into a footprint file. With the help of a text editor, I was able to manually layer everything into one complete image.
The KiCad design files are available on GitHub:
Junes-PhD has shared the project on OSH Park:
These magical creatures crop up out of nowhere and fry your electronics or annoy your ear holes. Understanding them will doubtless save you money and hassle. The ground loop in a nutshell is what happens when two separate devices (A and B) are connected to ground separately, and then also connected to each other through…

We are always surprised how much useful hacking gear is in the typical craft store. You just have to think outside the box. Need a hot air gun? Think embossing tool. A soldering iron? Check the stained glass section. Magnification gear? Sewing department. We’ve figured out that people who deal with beads use lots of fine…

On Saturday the Hackaday community turned out in force to try something new. The first Hackaday Unconference was held in three places at the same time, and I was in Chicago and was amazed at the turnout and variety of presentations. The image above sums up the concept quite well, everyone shows up ready to…
Eric Brombaugh designed this ADC board for RF signals:
This is an ADC designed for use in digitizing RF signals with up to 40MHz bandwidth and 80dB SNR. The form-factor is compatible with a dual-connector Digilent Pmod so that it can be used with commonly available FPGA development boards to build a variety Software-Defined radio functions.
- ADC14C105 14-bit 105MSPS RXADC.
- Onboard 3.3V Regulator (5V input)
- Filtered Analog 3.3V Supply
- Onboard 80MHz clock oscillator
- Digilent-compatible 2-connector Pmod interface
- 50-ohm SMA input – 2.5Vpp ~= 0dBfs

Brian Benchoff of Hackaday writes about a surprise PCB he received at the Hackady Unconference in Chicago last weekend:
For the last few years, Hackaday has really been stepping up our game with marketing materials. Our t-shirts and swag are second to none, and last year we introduced the ‘Benchoff Buck’ [..]
Andrew Sowa created the Benchoff Nickel. It’s a visage of yours truly emblazoned on a PCB, rendered in FR4, silkscreen, gold, and OSHPark’s royal purple.
The Benchoff Nickel was created in KiCad using the Bitmap2Component functionality. Planning this required a little bit of work; there are only five colors you can get on an OSH Park PCB, from white to gold to beige to purple (soldermask on top of copper) to black (soldermask with no copper). Luckily, the best picture we have of me renders very well in five colors.
We are excited for the 2017 Open Hardware Summit this Fall in Denver, and we’re pleased to see the Ada Lovelace Fellowship is now open for applications:
The Ada Lovelace Fellowship encourages women, LGBTA+, and/or other minorities in the open technology movement to both participate and nurture an incredible, diverse community within open source.
For the fifth year running, we are ecstatic to offer TEN (10) Open Hardware Fellowships to members of the community. This includes travel assistance and entrance to the 2017 open Hardware Summit!
We are at an exciting point in time for open source and hope to encourage everyone, no matter their walk in life, to embrace and participate in this incredible movement!
