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:

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):

Michael used vacuum pickup tool to manually place the components:

Michael then used Reflowster to reflow the solder paste:

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!

USB Interruptor

Teensy creator Paul Stoffregen designed this board to momentarily disconnect a USB device:

USB Interruptor

This simple board plugs inline with a USB cable. It always passes the 5V power and normally passes the USB data signals. But when you press the button, the USB data signals are momentarily disconnected.

For the last few months I’ve been developing a USB Host Library for powerful but complex EHCI USB port in Teensy 3.6 [..] Reaching over to physically unplug the USB cable gets old quickly! Really, really old, both hands off my keyboard… right when trying to focus [..]  I made this handy little board with a proper USB 2.0 high speed mux chip. The control signal is just 3.3V logic, so I might even wire it up to something to automate the process.

Star Trek Communicator Badge

Joe Crop is a creating a real life version of this famous sci-fi device:

Star Trek Communicator Badge

In the true spirit of Star Trek, this communicator badge is completely autonomous, while fitting in the form factor of an original badge

https://hackaday.io/project/19700-star-trek-communicator-badge
https://hackaday.io/project/19700-star-trek-communicator-badge

Star Trek was known for dreaming up technology that was deemed nearly impossible given the limitations of the technology for the day. Having a small badge that could send audio across vast distances seemed out of the realm of possibility during the late 1980’s. This project’s aim is to use modern technology to provide nearly all the features of visionary tech, namely:

– Tap to connect and communicate instantly
– Long range (from orbit to planet surface)
– Small form factor (of an original TNG badge)
– Fully autonomous (no cell phone or base station needed)
– No external power source (i.e. battery powered)
