Hackaday Prize Entry: BeagleLogic
A few years ago, [Kumar] created the BeagleLogic, a 14-channel, 100 MSPS logic analyzer for the BeagleBone as an entry for the Hackaday Prize. This is a fantastic tool that takes advantage of the PRUs in the BeagleBone to give anyone with a BeagleBone a very capable logic analyzer for not much cash. This year,…

Hackaday Prize Entry: Health-Monitoring Flexible Smartwatch
[Nick Ames]’s Flexible Smartwatch project aims to create an Open Source smartwatch made out of a flexible, capacitive e-ink touchscreen that uses the whole surface of the band. This wraparound smartwatch displays information from the on-board pulse and blood oximetry sensor as well as the accelerometer and magnetometer, giving you a clear idea of how stressed…
ADSR Envelope Generator Module
What’s an ADSR envelope generator? If you are a big music hacker, you probably know. If you are like the rest of us, you might need to read [Mich’s] post to find out that it is an attack-decay-sustain-release (ADSR) envelope generator. Still confused? It is a circuit used in music synthesis. You can see a…
Best Product Entry: Emulating Memory
For this year’s Hackaday Prize, we’re giving everyone the opportunity to be a hardware startup. This is the Best Product portion of the Hackaday Prize, a contest that will award $30,000 and a residency in our Design Lab to the best hardware project that is also a product. Imagine all the memory chips in all…
Open Narrowband RF Transceiver
We have so many options when we wish to add wireless control to our devices, as technology has delivered a stream of inexpensive devices and breakout boards for our experimentation. A few dollars will secure you all your wireless needs, it seems almost whatever your chosen frequency or protocol. There is a problem with this…

Want to try flex?
UPDATE 2018-01-03:
We are still testing our flex process. We just sent our second round off to fab this week.
The previous round was delivered to folks starting Hackaday Supercon weekend back in November 2017. Here some more information:
We were pleased to see Trammell Hudson’s creative Catalan design:
Henner Zeller also designed a very nice LED ring for his DerKnopf project:
For more information, please email: [email protected]
We’re looking for a variety of flex designs to test. The specs will be the same as our normal 2 layer service but on Kapton:
6 mil minimum trace width6 mil minimum trace spacing10 mil minimum drill5 mil annular ring
Please send us an email with “flex” in the subject: [email protected]
1Bitsy 1UP handheld game console
We’re excited about this new project from Piotr Esden-Tempski of 1BitSquared on Hackaday.io:
1Bitsy 1UP
1Bitsy 1UP is a retro inspired handheld game console, the design is based on the 1Bitsy STM32F415RGT6 ARM Cortex-M4F 168MHz 192kb RAM and 1MB Flash micro controller. 2.8″ TFT with capacitive touch, SDCard Reader and a few other components.
The display used is a TFT LCD with I2C CapTouch and ILI9341 driver. (should be compatible with the display sold by Adafruit on their breakouts as well as the buydisplay.com 2.8″ tft with CapTouch sensor)
The most basic design consists of:
- 1Bitsy STM32F415RGT6 (168MHz, 192kb RAM, 1MB Flash)
- 240×320 2.8″ TFT with capacitive touch and PWM backlight control
- D-Pad, ABXY, Start, Select buttons
- DAC audio out to headphones. (speakers optional)
- SDCard connected over SDIO interface
The hardware design files and firmware source code are available on GitHub:

Pi0CKET-tiny
From moosepr on Hackaday.io:
Pi0CKET-tiny
Possibly the worlds smallest Pi based gaming device!
Our 0.8mm thickness 2 layer service was used to make it as slim as possible:
The designs for a 3-D printed case are shared on the Hackaday.io project page:
Dooba.io open source MP3 player
MP3 player design from Dooba.io:
Shiva: MP3 player for the masses
Based on the ioNode, Aecho and Nomad modules, the Shiva allows browsing & playing MP3 files stored on any FAT-formatted MicroSD card with audio quality up to 128Kbps.
The actual Shiva board itself is quite simple, featuring an MCP23008 from Microchip for reading the 7 buttons, a DM3D-SF MicroSD card socket from Hirose and a 128×64 OLED display from Adafruit.
To keep everything neatly together I needed an enclosure. Being lucky enough to own a half-decent 3D printer I decided to keep things minimal but functional. Who needs glue and screws when you can go for a press-fit case?
The code for the Shiva MP3 player is available in the Dooba Firmware SDK under /src/shiva. Schematic and board are available in the Dooba Hardware collection.
