X Chapters

Somewhat timely, on our weekly show, we talked about the counterfeits on Amazon of “The Art of Electronics by Horowitz & Hill” – we (Adafruit) purchase the books directly from the publisher (Cambridge Press), and then we see the same book on Amazon cheaper. Some of real, some were counterfeits, but we’ll never get the same kill-everyone-else pricing that Amazon does, or the same pricing a counterfeiter can do. We usually are pretty close with the pricing, but sometimes our price is a little more. The good news (sorta?) is that we have a ton of customers who have been burned by Amazon over the years, from counterfeit textbooks to counterfeit products, so specifically for the Art of Electronics, getting it from Adafruit is the for-sure way to make sure it’s the real version. We now have the X Chapters in stock and it’s the real one of course.

Simple, but effective! – YouTube.

Sensor plotting

Testing out sensor plotting directly on the CLUE display. We wrote a plotter/scope for the CLUE in Arduino. You can plot any of the built in sensors (light, temperature, pressure, humidity, color, proximity, accel, gyro, mag) all directly on the 240×240 display. We even added auto-scaling! this makes it really easy to test out the sensors and measure the world around us. Code – GitHub.

9 DoF

Displaying 9 DoF orientation in a browser using webserial with CLUE. The CLUE board has a 9 DoF motion sensor (accel/gyro/mag) that can be used to calculate orientation (video). It’s hard to visualize using just text. Normally, folks would use a Processing sketch to display the 3D model, but now that webserial is available in the browser, it’s much easier to use that! This website uses webserial to get the Euler angles & three.js to display a bunny that moves around. We’ll update it to use quaternions next – YouTube.

What’s the team up to this week?

What is the team up to this week? Let’s check in!

Bryan

Bryan

This past week has been a fun time, working on a project and guide to make a Sip and Puff device that requires no soldering and very minimal code! I was able to make use of the Feather STM32F505 and its built in STEMMA QT connector to easily plug it into an ST LPS33HW ported pressure sensor, as well as a STEMMA QT OLED screen to output status and configuration information.

Bryan

Along the way, I also learned a lot about Assistive Technology and the plethora of makers helping support it, making it more accessible and even more functional. ATMakers.org and Makers Making Change are two great organizations that are helping get AT devices, based on Open Source Hardware and Software, into the hands of folks that need it.

I’m happy to do what I can to contribute, and while the sip and puff I was able to put together is one among many, I look forward to contributing wherever I can.

The Sip and Puff guide is out now, so head over and take a look. See how you can use it, or one of the many other open source AT projects, to make a difference for people that need some assistance.

Dan

This week I fixed several of the remaining issues that needed resolution before we release CircuitPython 5.0.0 for general availability. On nRF boards, I coded around a hardware bug, so we can now use the fast SPI peripheral. The CLUE board display is now a lot faster. For all builds, I improved the accuracy of the time module functions from milliseconds to microseconds.

I helped Dylan and John Park use the BLE bicycle sensor library I wrote last week for a fun project. You’ll be seeing the Learn Guide for it soon.

We had a head-scratching bug about why I2C operations were getting slower and slower when used in a loop. I spent a lot of time on this, but it turns out it had nothing to do with I2C per se. Instead was due to a particular pattern storage allocations in the adafruit_bus_device library. I made the library more efficient, and the issue provoked Scott to make the storage allocator faster

Jeff

Jeff

I’m going on the road for a couple of weeks and packing just the basics to continue on my work with ulab and JEplayer.

When I’m not sightseeing, I’ll be busy with improvements to ulab, a numpy-like package for CircuitPython, and porting JEplayer’s UI to the PyPortal Pynt’s touchscreen.

Kattni

This week I published the Introducing Adafruit CLUE guide. This guide has detailed information about all the features of CLUE with a thorough Pinouts page including images and a fancy edge-connector pinout diagram (courtesy of Andrew Tribble!), as well as setup instructions for both Arduino and CircuitPython.

Kattni

Next, I worked on a series of CLUE demos using the new CLUE library: a height calculator, a spirit level, and a temperature and humidity monitor. I put together a quick guide page for each that will be available soon. They can be found under CLUE CircuitPython Demos in the Introducing Adafruit CLUE guide. The plan is to extend this series of demos. Next up is a compass demo. After that, who knows! There’s so many options with the CLUE, the possibilities are endless!

Melissa

This past week, I continued working on WebSerial and adapting it to work with the new CLUE for calibrating the IMU sensor. Unfortunately, I kept running into an issue where it seemed to get overwhelmed by too much data and would slow way down, so I will probably be taking a different approach.

In order to gather my thoughts a little better, I switched over to working on Github issues for a few days. I’ve been focusing mostly on fixing some outstanding display issues and added a couple of new shapes to the Adafruit_CircuitPython_Display_Shapes library. Afterwards, I’ll be switching back to working on the CLUE board and IMU sensor again.

Scott

Last week I continued work on BroadcastNet. I’ve started getting PRs out, but everything is still pending. This week I’m working on using a Raspberry Pi 3 as a BroadcastNet bridge, with the hope it will be more reliable than an ESP32 wifi link. I’m very excited to use Ethernet for it.

Over the weekend, I attended PyCascades 2020 and it was great to see a bunch of awesome Pythonistas. I was the last talk and the video of it is available. – YouTube

This week so far, I took a detour into memory allocation performance, after Ladyada and Dan found something really weird. It was a really tight loop reading accelerometer data and storing it, where the gaps between reads increased from 1 ms to 10 ms and then reset. Turns out it was an un-optimized allocation case which I’ve now optimized as well. So, check out the last builds and let us know how it’s (hopefully) improved performance for you.
