CAD Renders from Overhaul 2 Redesign

Charles Guan from etotheipiplusone.net has been redesigning Overhaul from BattleBots season 6 as … Overhaul 2! This blog on the project has some interesting CAD renderings, along with tips & tricks for layouts, airflow, etc.

I decided to start with the “known known” and package the batteries up first. They were going to occupy the only large contiguous space in the back of the bot, which was originally designed to fit four of the Hobbyking Nano-Tech 8Ah packs that OH1 used. These are actually slightly shorter than two of those back-to-back, so I had a little more room to play with. I made a “minimum dimensional enclosure that’s a clean fraction above the size of the packs”. The enclosure will be made of 1/4″ polycarbonate, likely waterjet-cut, with plenty of my special-sauce t-nut joints holding everything together. This part I’ve done dozens of times, so I left the geometry simple for the time being in order to move onto the rest of the system.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
