Hackaday Prize 2022: PewPew LCD Plays With Python

The new PewPew with an LCD showing some patterns, being held in someone's hand.

[deshipu] aka [Radomir Dopieralski] has been building educational handhelds for a good part of a decade now, and knows how to design hardware that makes for effective teaching. Today, we are graced with the PewPew LCD project, latest in the PewPew student-friendly handheld series, powered by CircuitPython.

This time, as an entry in the Reuse, Recycle, Revamp round of Hackaday Prize, the new PewPew receives an upgrade – from an 8×8 LED matrix to an LCD display. This might not sound like much, but the change of display technology itself isn’t the main point. [deshipu] is working on ways to bring down the price and assembly complexity of PewPew handhelds, and he’s found there’s plenty of old stock RH-112 displays, previously used on cellphones like Nokia 1202, which these days go for as little as $1.30 a piece.

It’s exceptionally simple to get into writing games for the PewPew – one of the reasons why it’s a strong platform for workshops and individual learning. There’s already a slew of games and tutorials, and we can’t wait to see all the cool games people can build when given all the extra pixels! And, of course, we appreciate setting an example for giving new life to old displays – displays that’d otherwise inevitably end up in a trash container behind a warehouse in China.

The Reuse, Recycle, Revamp Hackaday Prize 2022 round is going on for two more weeks. If you’re making good use of something that would otherwise be discarded, please do share it with us, so that we can all learn and draw inspiration from your projects!

  1. What is up with the hackaday.io page for this post? There’s a clickable image, I need to see a bigger version so I click it. A new tab automatically opens and nothing is displayed. The new tab says “(GIF Image, 1 x 1 pixels)”. Its URL is:

    data:image/gif;base64,R0lGODlhAQABAIAAAP///wAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw==

    I am using the latest mainstream Firefox browser version. The picture I clicked is in this page, a picture of an LCD about half way down:

    I tried the same thing in Microsoft Edge and it worked OK, the new image appeared at this URL:

    https://cdn.hackaday.io/images/6178221646299570694.jpg

    So maybe hackaday.io is redirecting the connection automatically while tracking me with a one pixel .gif? If yes that’s not secure; Edge allows it Firefox doesn’t? Hmmm… See this:
