Making our code run 45,000% faster - Fetch #7 Applied Procrastination 2019-09-11 | We've been optimizing our embedded system for faster code so we could fix some necessary features. Most of the performance boost comes from upgrading from an Arduino Mega to a Teensy 3.6, but a lot of it is also down to doing some changes to our hardware connections in order to parallelize huge chunks of the shifting out process. As a student-project at the University of Oslo, we have designed and built a massive ferrofluid-display with 252 electromagnetic "pixels". On Applied Procrastination we will share all the details of this project and hopefully inspire you to make something similar - or follow your own dream projects. --------------Twitter: twitter.com/AppliedProcFacebook: facebook.com/AppliedProcInstagram: instagram.com/appliedprocrastination--------------Open Source files and project details:Code:Github repositories (Firmware+CAD+python parser): github.com/AppliedProcrastinationPCB files & more details:Instructables: instructables.com/id/Mesmerizing-Ferrofluid-Display-Silently-ControlledHackaday.io: hackaday.io/project/167056-fetch-a-ferrofluid-displayHackster.io: hackster.io/AppliedProc/fetch-a-ferrofluid-display-ca8557Arduino project hub: create.arduino.cc/projecthub/AppliedProc/fetch-a-ferrofluid-display-ca8557--------------Whitepapers and references from the episode:Larry Bank, "Mr. Optimization": bitbanksoftware.blogspot.comAdafruit, "Memories of an Arduino": cdn-learn.adafruit.com/downloads/pdf/memories-of-an-arduino.pdf"DSP capabilities of ARM Cortex-M processors": community.arm.com/developer/ip-products/processors/b/processors-ip-blog/posts/white-paper-dsp-capabilities-of-cortex-m4-and-cortex-m7--------------Credits:Audio Mastering: - Haldor August Sørmoen: Intro/Theme song: - Nicklas Myhre: instagram.com/myhre.nicklasMusic: - Summer from Bensound.com - Slow Motion from Bensound.comSound Effect Mixing: - Eivind Rostad

Improving The Worlds Largest Open-Source Ferrofluid Display Applied Procrastination 2021-08-25 | If you’ve followed us for a while, you know that displaying ferrofluid vertically comes with challenges. To counteract gravity, the electromagnets must be able to change how much force they apply on the ferrofluid - a problem we can solve with pulse width modulation. Previously we’ve implemented PWM in software, which is seriously ineffective. We’ve already made a whole video on how we optimized this to work at all ( youtube.com/watch?v=ZXVIQhwBu1w ).The main idea of our new PCB design is to move PWM away from the microcontroller, simplifying the code a ton. We achieve this by abusing LED drivers. LED drivers are a type of ICs that typically aren't meant to provide any logic-signals and are not rated to sink enough current for an electromagnet to turn on (each channel can typically sink around 20mA, where closer to 200mA is necessary for an electromagnet (rough numbers)). The only LED driver we found that could satisfy our needs was PCA9685. It can be set up in a totem pole configuration, which allows us to use it more as a GPIO expander with PWM capabilities than as an LED driver. This means we can daisy-chain the PCA9685 with a ULN2803 Darlington Transistor array – which, in turn, has the capacity to sink enough current for the magnets. --------------Twitter: twitter.com/AppliedProcFacebook: facebook.com/AppliedProcInstagram: instagram.com/appliedprocrastination--------------Open Source files and project details:Code:Github repos: github.com/AppliedProcrastination/FerroFetchFirmwaregithub.com/appliedprocrastination/AprocAnimationgithub.com/appliedprocrastination/MagnetControllerV2-libraryPCB files & more details:Github repo: github.com/appliedprocrastination/FetchCADFilesInstructables: instructables.com/Mesmerizing-Ferrofluid-Display-Silently-ControlledHackaday.io: hackaday.io/project/167056-fetch-a-ferrofluid-displayHackster.io: hackster.io/AppliedProc/fetch-a-ferrofluid-display-ca8557Arduino project hub: create.arduino.cc/projecthub/AppliedProc/fetch-a-ferrofluid-display-ca8557--------------Credits:Intro/Theme song: - Nicklas Myhre: instagram.com/myhre.nicklas

Worlds Largest Open-Source Ferrofluid Display - Fetch #8 Applied Procrastination 2019-11-29 | Fetch is DONE! This is huge for us. We've now spent two years working on our open-source ferrofluid display as a side project to full-time studies and part-time jobs. We've compiled a series of sweet sweet animations and spent a long time perfecting this video. We hope you enjoy it!Since last time we've hidden the cable chaos. For the initial version of "Fetch" we wanted to use laser cut plywood as a chassis, because it's a very replicable and simple solution. We will look into a making a neater metal finish in the next version, which will be considerably sleeker, for an even cleaner look. We make the animations in Aseprite, a powerful and free* pixel art editor, and parse them into a format we've found easy to read on the Teensy 3.6 that's at the heart of the platform. (*As long as you can compile the source code yourself. ) Future projects :While Fetch is now complete, we are not done working with ferrofluid, or electronics for that matter. We are currently researching ways of making a "flat screen" version, and even much smaller ferrofluid displays that are cheaper to replicate. We are also working on implementing more software features, like video-games, in the version we've already made. This paragraph marks the end of the project, but not the end of our ferrofluid display endeavors. Stay tuned! For our own convenience, we also added a few buttons and switches that makes it simpler to show a variety of animations when displaying the project at maker festivals.As a student-project at the University of Oslo, we have designed and built a massive ferrofluid-display with 252 electromagnetic "pixels". -------------- Twitter: twitter.com/AppliedProcFacebook: facebook.com/AppliedProcInstagram: instagram.com/appliedprocrastination --------------Open Source files and project details: Code:Github repositories (Firmware+CAD+python parser): github.com/AppliedProcrastination PCB files & more details:Instructables: instructables.com/id/Mesmerizing-Ferrofluid-Display-Silently-ControlledHackaday.io: hackaday.io/project/167056-fetch-a-ferrofluid-displayHackster.io: hackster.io/AppliedProc/fetch-a-ferrofluid-display-ca8557Arduino project hub: create.arduino.cc/projecthub/AppliedProc/fetch-a-ferrofluid-display-ca8557 --------------Credits: Audio Mastering: - Haldor August Sørmoen: Intro/Theme song: - Nicklas Myhre: instagram.com/myhre.nicklas Music: - Get to Know You (Instrumental Version) - Cody Francis from EpidemicSound.com - Applied Procrastination by Nicklas Myhre - Mexico (Instrumental Version) - Gamma Skies from EpidemicSound.com - Endless motion from Bensound.com Sound Effect Mixing: - Eivind RostadAseprite:aseprite.org
Simplified Neuralizer-prop from Men in Black - Misc #2 Applied Procrastination 2019-10-29 | We wanted to make a costume-prop for Halloween that resembles the Neuralizer from Men in Black. However, we wanted to make sure that it has super simple, working, electronics so that it can be whipped together at the last minute! Therefore, we designed this 3D model which could fit a capacitor based flash/blitz circuit running on a normal 9 Volt battery. The flash itself is a 10 Watt LED (Voltage drop: 12V, max current 900mA), but could easily be replaced by a more common LED (just make sure to change the value of the current limiting resistor). The specs of an LED will depend on the color it emits, but 2V and 20mA seems to be a decent choice of parameters in many cases (read more here: electronicsclub.info/leds.htm). To calculate the size you need for a current limiting resistor, use a LED calculator and find specs in the LED datasheet, or use the values I provided above: http://ledcalc.com . Keep in mind that if you switch out the battery with something other than 9V you will have to redo the current limiting resistor calculation. We believe that the circuit design we show here is the simplest possible capacitor based LED flash. When the 3D design was done, we printed it out, sanded down the layer lines with a 80 grit sandpaper, then primed it with a cheap plastic filler (made for car bumpers - the exact brand shouldn't matter at all). We repeated this process until the finish was smooth and free of obvious holes. We then used a black primer paint on the parts that we wanted to stay black (near the LED opening in the lid), before assembling the electronics and gluing everything together. We used hot glue, but immediately regretted that decision because it cooled down too fast so it was impossible to tune the alignment of the pieces. We should have used a contact glue or an epoxy. When this was done, we primed the rest of the piece with black paint, then went on to do a few layers of silver, and finishing off with a clear coat to protect the paint.--------------Open Source files:Instructable: instructables.com/id/Worlds-Simplest-Neuralizer-build-Men-in-Black-MemoWriteup: hackaday.io/project/168234-simplified-neuralizer-with-working-electronics3D files: printables.com/model/344052-worlds-simplest-neuralizer-men-in-black-memory-era--------------Twitter: twitter.com/AppliedProcFacebook: facebook.com/AppliedProcInstagram: instagram.com/appliedprocrastination--------------Credits:Intro/Theme song: - Nicklas Myhre: instagram.com/myhre.nicklasMusic: - Funny Song from Bensound.com - Endless Motion from Bensound.com - Little Idea from Bensound.comSound Effect Mixing: - Eivind Rostad
