Eff-Uno Racer v1 by chrisbensen – Thingiverse: Open Wheel Race Car from LEGO© and 3D printed bricks, with RC motors controlled by a Raspberry Pi and Arduino

Posted by jpluimers on 2022/08/17

This is so cool!

[Wayback/Archive.is] Eff-Uno Racer v1 by chrisbensen – Thingiverse

Welcome to the home for the things to print for the Eff-Uno Racer project ([Wayback/Archive.is] github.com/oracle-devrel/eff-uno-racer). Eff-Uno Racer is a LEGO© Open Wheel Race Car that you can build and remotely control. Most of it is made with LEGO© bricks but the motors are regular RC motors controlled by a Raspberry Pi and Arduino. Below are the extra parts needed.

The videos are via these three tweets:

List is at: [Wayback/Archive.is] Cool DevRebel Projects – YouTube

Videos when writing (by now there should be more):

  1. [Wayback/Archive.is] Cloud Car Episode 1 — Custom Breadboard for Pi Zero – YouTube
  2. [Wayback/Archive.is] Cloud Car Episode 2 — Pi Controlled Motors – YouTube
  3. [Wayback/Archive.is] Cloud Car Episode 3 — Shoving a Pi & RC Motor into a Toy Car – YouTube
  4. [Wayback/Archive.is] Episode 4: Shoving a Motor and Speed Controller into a Toy Car – YouTube
  5. [Wayback/Archive.is] Episode 5 — Next Stage: 3D Printed RC Servo Motor Adapters – YouTube

Via [Archive.is] Chris Bensen on Twitter: “If you want to build your own open source cloud connected toy race car follow this thing”

Some @MCH2022Camp badge updates I found on Twitter

Posted by jpluimers on 2022/07/19

For all attending [Wayback/Archive] May Contain Hackers 2022 , a few things to check out:

  • their blog contains new posts with exiting news: [Wayback/Archive] Weblog | May Contain Hackers 2022 – blog
  • Tweeps and tweep-groups are fiddling with the MCH2022 badge already resulting in cool things like:
    • The MCH2022 terrain as a gameboy map (which runs on the MCH2022 badge)
    • There is a batch housing you can 3D print
    • Thumb knobs for the MCH2022 badge to it is easier on your fingers (2 models)
    • More software to run on the MCH2022 badge (like a CTF game)
    • Doom running on the badge (that of course was just a matter of time)
    • After MCH2022 there are 3 more hackercamps in Europe

More below…

Last days until the May Contain Hackers 2022 camp; the badge project can still use some help on the software side: Python apps, FPGA, documentation, etc

Posted by jpluimers on 2022/07/11

After yesterdays post (which I will be editing to add some more pictures) MCH2022 badge sneak previews from tweeps that attended the Bitlair 20220709 Sweatshop (@MCH2022Camp) now a call for help:

The Badge Team needs volunteers helping them on the software side.

At the badge event, the version 1.0 firmware was flashed so the badge will function perfectly fine during the event, but it would be cool if more features are available that attendees can get when upgrading at the event or downloading from the hatchery.

There is a virtual environment to test and a GitHub projects page with open issues to get started.

See the links below on how you can help:

MCH2022 badge sneak previews from tweeps that attended the Bitlair 20220709 Sweatshop (@MCH2022Camp)

Posted by jpluimers on 2022/07/10

The MCH2022 badge has an ESP32 (with WiFi!), a RP2040 and an FPGA next to a full colour TFT LCD, buttons (including joystick!), LEDs, LiPo battery, USB-C connector, micro SD-card slot and more (see below) and SHA2017 badge compatibility. How cool is that!

There is a wealth on information for this at [Wayback/Archive] Badge.team (some 22 repositories and counting: [Wayback/Archive] Badge.team: search for repositories containing mch2022).

Good starts are [Wayback/Archive] MCH2022 badge | BADGE.TEAM and [Wayback/Archive] Software Development | BADGE.TEAM (yes of course you can write your own software for it and even distribute it through the [Wayback/Archive] hatchery.badge.team Hatchery).

Below are lots of tweets including some of the Twitter retrospect that organically grew (just like the sweatschop event) on Twitter the day after.

From the original announcement [Wayback/Archive] May Contain Hackers 2022: Presenting: The MCH2022 badge! , this is what hardware is in it

Jeff Geerling on Twitter: “I plug computers into my computers…” is indeed a PCIe KVM board based on a Raspberry Pi Compute Module 4

Posted by jpluimers on 2022/05/10

Last month, I wrote

Hopefully the picture below is the board of a PCIe KVM board based on a Raspberry Pi Compute Module 4 supporting Power over Ethernet (PoE). At least it seems to looking at the thread started by…

The thread was by Jeff Geerling on Twitter: “I plug computers into my computers…”.

Jeff followed up on this much sooner than I expected with [Wayback/Archive] Jeff Geerling on Twitter: “Hey look! That computer inside a computer thing is real now! It’s the PCIe version of the Blicube KVM: …”
