So finally the boards and parts are here and I built the first batch of 3 boards (purple as in oshpark.com). Here is a photo of one of them with my hand as size reference: This board is twice the size of the original SDI-12 USB adapter and features the following additional features: 4 SDI-12
It has been quite a ride this year, watching entries pour in during the five challenges of the 2016 Hackaday Prize. Our yearly engineering initiative is designed to focus the skill, experience, and creativity of the world’s tinkerers, hackers, designers, and fabricators to build something that matters: things that change lives.

Amateur radio enthusiasts in the US will be interested in Faraday, an open-source digital radio that runs on 915 MHz, which amateur radio enthusiasts may know better as the 33 cm band. You can transmit on 915 MHz without a license (in the US), taking advantage of the Industrial, Scientific, and Medical (ISM) exemption.

Having my reflow solder oven finished, I couldn’t wait to see how far can I challenge it with complex circuit boards and tiny components. I decided to build a system with components that are tricky to solder, such as BGA and QFN packages. Not interested in designing the whole circuit on my own, I […]

Benjamin Shockley designed this adorable Atmel SAMD21 dev board in the shape of Lego mini-figures!
This circuit board was designed as a fun project for a SAMD21E microcontroller based development board. The circuit design follows the recommended design from the SAMD Datasheet.
The design files are shared on GitHub:

Carlos of GlowSaber wrote a great blog post on how we built an AVR programmer shield:
As I learned more about Arduino, I realized that it is possible to redesign the GlowSaber around the ATmega328 chip [..] I designed an Arduino Shield that can be used to burn the bootloader and upload programs to an ATmega328 chip.
Here’s a example of an ATmega328 in a custom board:

davedarko wrote in his LED displays on Arduinos – a collection project log on hackaday.io:
With 4 of HP QDSP-6064 bubble displays in a drawer I felt ready to do something with them and the “Clocks for Social Good” – call on hackaday.com finally got me going
The design files are available on GitHub:
davedarko’s mum gave him some small jam jars and it inspired him to design this clock:
30ml jam jars hopefully turned into beautiful LED displays – nixietube like looking without the higher voltage fuzz – fake LED nixietubes

Here’s a video of the clock in action:
Be able to make & upload MagSpoof with variable tracks, to use it without Arduino dependencies, and implement it on the same Raspberry GPIO.
More details are available on Salvador’s blog.
The makefile and the modified MagSpoof library are avialabel on GitHub:
MagSpoofPI
The board can be used to monitor the environment conditions, and store or transmit the data to a remote system for further processing.
