E-ink Display Driven DIY

E-ink displays are awesome. Humans spent centuries reading non-backlit devices, and frankly it’s a lot easier on the eyes. But have you looked into driving one of these critters yourself? It’s a nightmare. So chapeau! to [Julien] for his FPGA-based implementation that not only uses our favorite open-source FPGA toolchain, and serves as an open reference implementation for anyone else who’s interested.

Watch the E-Ink controller in action:

Design files and source code are available on GitHub:

Manual assembly of KiCad PocketBone

We’re excited to see that Michael Welling of QWERTY Embedded Design has completed manual assembly of his KiCad-designed PocketBone with the Octavo Systems OSD3358 SiP (System-in-Package):

BGA achievement unlocked

Michael used vacuum pickup tool to manually place the components:

Here is a video of him placing the components:

Michael then used Reflowster to reflow the solder paste:

16 - 1

Here is a video of the reflow process:

Servo Shield for OpenMV

Radomir Dopieralski created this PCA9685-based servo shield for the OpenMV machine vision board:

Servo Shield for OpenMV

OpenMV has a couple of pins that you can use for connecting servos (for example, if you want to mount it on a pan-and-tilt base), but you can’t use those if you also want to use the WiFi shield or any other shield that uses up a lot of pins. Practically the only pins left to use are the I²C ones

High-speed ADC pHAT for Raspberry Pi

kelu124 designed this board to add high-speed analog inputs to the Raspberry Pi:

20Msps+ ADC RaspberryPi extension

We haven’t tapped yet into the full potential of the Raspberry Pi in terms of ADC. Some have shown that the first gen of Raspberry could go to 10Msps [..] My take is that the new Raspberry Pi’s  can surely go above. And I want to try it, either with this old CA3306E or with more recent kick-ass ADCs.

3D Printed USB Connector

chmod775 on Hackaday.io designed this simple 3D Printed USB Connector compatible with PCBs from OSH Park:

3D Printed USB Connector

I’ve made this 3D USB Connector because I want to remove the chunky and complex standard metal USB Connector from my new upcoming project.
The design it’s made to be simple and with the height reference from the OSHP ark PCB’s.

PCB Painting Large Pieces

David I. Herman made some impressive new PCB painting pieces, demonstrating subtleties in shading and Art Nouveau inspiration, precision produced by OSH Park

We are trying to figure out what direction to take this blend of technology and art — should we offer pieces for sale, or offer a service for making your own pieces from your own artwork, for instance. We’re certainly going to continue to explore it from a technology and art creative point of view. If you feel inclined, please take a moment to leave a comment, we are interested in your feedback!
