Upgrading to Sharp 128×128 Pixel Memory Display


In “Low Power LCD: Adafruit Breakout Board with Sharp Memory Display” I used a 96×96 Sharp Display (LS013B4DN04) with the Adafruit breakout board, but because that one seems to be EOL (End Of Life), I searched for a replacement. I have found the 128×128 pixel version (Sharp LS013B7DH03), and best of all, it is pin compatible :-). With a small tweak of the driver, it works :-):

Low Power LCD: Adafruit Breakout Board with Sharp Memory Display


Many projects benefit from a small display as a user interface. For very low power applications this is usually a no-go as the display needs too much energy. I have used e-paper displays from Kent: while these e-paper displays do not need any power to keep the image, changing the display content is not for free, plus is very slow (around 1 second needed to update the display). So I was looking for something low power and fast for a long time, until Christian (thanks!) pointed me to a display from Sharp: both very low power and fast:

MINTomat: World’s Most Complicated Bubble Gum Automata?


How to fascinate kids for technology? Show them that engineering is fun :-). At the Lucerne University of Applied Sciences and Arts we have created the ‘MINTomat’: a robotics system for STEM activities rewarding interaction with bubble gums:

Yes, pretty over engineered compared to a normal bubble gum automata, but that’s part of the fun :-).

Enclosure for the Remote Robot Controller with LCD Display


The first enclosure for the INTRO robot remote controller board (see “INTRO Robot Remote – First Production PCB“) is ready, and it is looking good:

3D Printed Gameboy and Remote Controller with tinyK20 Board


As a remote controller for the Sumo robot (see “Zumo Robot with Magnetic Encoders“) we have used so far a combination of NXP FRDM-KL25Z board and a Joystick Shield (see “Joystick Shield with nRF24L01 driving a Zumo Robot“). That solution was not ideal, so this weekend I created a 3D printed prototype:

nRF24L01+ 2.4 GHz Wireless Connectivity with the tinyK20 Board


I’m using the tiny and inexpensive Nordic Semiconductor nRF24L01+ transceiver (see “Tutorial: Nordic Semiconductor nRF24L01+ with the Freescale FRDM-K64F Board“) in many projects: it costs less than $3 and allows me to communicate with a proprietary 2.4GHz protocol in a low power way (see “IoT: FreeRTOS Down to the Micro Amps“). I have that transceiver now running with the tinyK20 board too:

3D Printed Magical MUFG Capsule to Duplicate NXP Kinetis K20 Boards


Sometimes it is all about doing fun stuff: to carry and store the tinyK20 (NXP/Freescale Kinetis K20) boards needed for next course, I wanted to build something geeky: a MUFG capsule to store and duplicate Kinetis boards 🙂

First 3D Printed tinyK20 Board Enclosure


The tinyK20 boards are now used in several projects. Initially I was considering a commercial USB thumb drive enclosure for it. But this needed some tweaking of the enclosure so at the end it was not ideal. 3D printing is probably that hot topic for 2016. So why 3D printing an enclosure for that board?

Data Logger with tinyK20 Board


First off: The tinyK20 project is progressing fine and is now on Hackaday.io :-).

For a research project we would like to use the tinyK20 to log gyro sensor data. For this I have created a quick-n-dirty project to explore how feasible it is. The tinyK20 has all the pins on the outside of the board, so I’m able to put it on a bread board:
