ProtoStax How-To Videos

Hello there!

Hope you're having a great week!  Hope you're enjoying the long weekend for Memorial Day, and our salute and gratitude to all our service members in this day of remembrance and honoring. 

We are excited to premier our very first "How-To" video today, on this occasion!

If you are a ProtoStax user, this will supplement the existing User Manual in helping you get up and running and know about all the myriad features of ProtoStax and get the most out of your ProtoStax enclosures. 

If you are new to ProtoStax, this is a great way to learn more about it! We hope you will consider it for your next project - we think you will love it! 😊

As usual, if you have any comments or suggestions, we would love to see them in the comments section below!

Hi Geoff,

Thanks for your comments! I’m really glad you like it! 😊Yes, it would work perfectly with the Pi Zero W, but with a few modifications to fit everything in, as you’ve figured out!

There are a couple of things that you can do with regards to the ISS red lines – you can make the positions array a circular buffer and only keep the amount of data you are interested in (for example, the last 2 hours (or 240 data points if you’re polling every 30 seconds), so that older data would get aged out.

That, and you can run the script as a service. In addition, you’d want to do some try/catch blocks to handle errors where the data is not available. With those, you shouldn’t have to connect to your Pi again! 😊

Best Regards, .


Hello Sridhar

I’m really pleased with everything you have explained. The ProtoStax box, 2.7inch e-Paper HAT are great and I even got it all to fit together and work perfectly using my Raspberry Pi Zero W. that you didn’t mention as far as I could see. It runs Raspberry Buster latest version.

I have a query that maybe you can advise what I should do. After about a day, the ISS red lines on the HAT are all still present and I would like to automatically clear them as part of the Python code you provided.
Ideally, I would like to set up your “Running the script as a service” approach so all I need is a mains lead to my Raspberry Pi and I never want to connect again to the Raspberry Pi but its printed HAT screen must automatically clear every day without having to do the usual connection from RasPi to use a mouse and PC screen.

I used to teach Python at the UK Open University until I retired in December 2018, so I probably could understand anything you advise me.

Best wishes

Geoff Harmer
