Raspberry Pi Distance Sensor: How to setup the HC-SR04 #piday #raspberrypi @Raspberry_Pi

This guide will go through showing you how to wire up the sensor with the Raspberry Pi as well as exploring how we can utilize the sensor also to read distance.
We will be showing you how to wire the HC-SR04 sensor up to the Raspberry Pi, including how to wire a voltage divider as the circuit requires one to drop the 5v output from the sensor to 3.3v for the Raspberry Pi.

Better Electronics with Jupyter Notebooks by @Osterwood @capablerobot #CircuitPython @crowd_supply

Here’s material from Chris Osterwood’s Teardown2019 talk on using Jupyter Notebooks to aid in electrical design & testing. Via Twitter:

I had a blast the Crowd Supply’s Teardown 2019 conference and was thrilled to present how I’m using Jupyter Notebooks to aid electrical design & testing. I’ve open-sourced the notebooks: so fork, steal, CTRL-C/V, whatever. Video and notebooks are on GitHub.

If you find these useful please let me know, and also let me know if you publish your own notebooks publicly! I’d love to link to them and show the world more examples of notebooks aiding in product design and testing.

A video of the presentation is available on YouTube. And read more and see the notebooks on GitHub.

European Astro Pi Challenge: Mission Space Lab Winners! @Raspberry_Pi #PiDay #RaspberryPi

via RaspberryPi.org

This is your periodic reminder that there are two Raspberry Pi computers in space! That’s right — our Astro Pi units Ed and Izzy have called the International Space Station home since 2016, and we are proud to work with ESA Education to run the European Astro Pi Challenge, which allows students to conduct scientific investigations in space, by writing computer programs.

The Challenge has two missions: Mission Zero and Mission Space Lab. The more advanced one, Mission Space Lab, invites teams of students and young people under 19 years of age to enter by submitting an idea for a scientific experiment to be run on the Astro Pi units.

See and learn more!

How to Setup a Raspberry Pi Samba Server #piday #raspberrypi @Raspberry_Pi

via PiMyLifeUp

Samba is a re-implementation of the SMB (Server Message Block) networking protocol and allows Linux computers to integrate into Microsoft’s active directory environments seamlessly.
CIFS or Common Internet File System is an implementation of the SMB protocol. In modern setups, CIFs or SMB is used interchangeably, but most people will use the term SMB.

Benchmarking Machine Learning on the New Raspberry Pi 4, Model B @Hacksterio @Raspberry_Pi #PiDay #RaspberryPi

Awesome post from Alasdair Allan up on Hackster.io.

At the start of last month I sat down to benchmark the new generation of accelerator hardware intended to speed up machine learning inferencing on the edge. So I’d have a rough yardstick for comparison, I also ran the same benchmarks on the Raspberry Pi. Afterwards a lot of people complained that I should have been using TensorFlow Lite on the Raspberry Pi rather than full blown TensorFlow. They were right, it ran a lot faster.

Then with the release of the AI2GO framework from Xnor.ai, which uses next generation binary weight models, I looked at the inferencing speeds of these next generation of models in comparison to ‘traditional’ TensorFlow. This also ran a lot faster.
