Hi all, I am starting a new thread here to document and report my process of building a new bot based on the Raspberry Pi BuildHat. Comments and suggestions are all welcome. At the moment my bot is build with the following H/W - RPi 4b Buildhat Sensehat (for displaying a face and doing other measurements) A Rpi camera Raspberry Pi OS (debian buster, finished configuring the python libs for the hats and added remote access so I can deploy new python code to it) At the moment the bot can only tilt its head up and down, but in the next few days I will start adding tank tread for movement and a front grabber. Just in case you are interested in see what it looks like, here are some pics - Bot with camera, build hat and sense hat Bot with camera, buildhat and sensehat (side view) Looking forward to hear your feedback / comments. Have a good weekend! /cheung 8) -
Hi all, I would like to show you a MOC based on an already existing creation of @afolman which can be found on internet. It is a miniature Atari 2600 - woody version with four levers - it is very simple and quite solid. I reworked a bit the Joystick and the four levers, which are made by four silver minifig screwdrivers inside a Pneumatic pipe, squeezed by the two slope bricks. I saw many similar creations on Internet but I wanted to go one step beyond, making it functional and usable. I therefore designed it to be empty inside. In this way I could accomodate a very small Raspberry PI zero (without WI-FI) in it. I only had to remove a small plastic lid from the little motherboard (the lid can be put on again without problems). The Mini-HDMI to HDMI adapter was modified to reduce its size, but now I have a dedicated Mini-HDMI to HDMI cable which is surely nicer. Once installed the RetroPie distribution, and inserted all the roms...pardon...original cartridge images - I can bring my small 2600 everywhere! Thanks to @afolman for the inspiration. I hope you like it

I just saw this on kickstarter, quite nice idea :)

brebo Hi, I have launched a KickStarter (crowdfunding) campaign for a simple, low cost and intuitive system to invent and recycle electronics using Lego. Have a look [removed url] Let me know what you think. Thanks!

I have built a "Card Dealer" using raspberry pi with camera, some sensors, and 2 PF-Motors. It can sequential or random deal, recognize card, and play "13支"(Chinese Poker). Deal 52 cards into 4 separate piles in 4.6 seconds. (Turbo mode) And a "Lite" version. Lite(left) vs Normal(right) some pictures -
Here's something a little different, I needed a sorting machine using Tensorflow, Raspberry Pi and EV3 (with RPyc), so 45544 fit the bill pretty nicely. The project took a couple of weeks to get up and running mostly due to having no exposure to either EV3, Tensorflow or RPyC, but it is definitely achievable with some shoe-horning here and there. Don't hate my LEGO extension to the 45544 sorter too much, it was quick and nasty, the project isn't about the elegance of that side of things, it is more about making an end result that works doing something the EV3 can't on its own. And work it does, it is able to reliably discern 4 image types stuck onto 3D printed tiles (in place of the technics bricks). In the shorter term I will design and 3D print a support structure to hold the Raspberry Pi + camera. That part will be done using driven design workflow in Autodesk Inventor, feeding in known LEGO brick dimensions for quick & easy parts alignment. In the longer term I can see the addition of a vibratory bowl feeder with tiles being recycled after sorting for continuous operation. Right now it is a technology demonstrator that will be used to introduce school children to some modern technology, I should be able to complete a design manual for them to replicate my working design. Check it out if you're at all interested in controlling the EV3 externally to greatly expand its functionality: https://www.youtube.com/watch?v=wSSh9iV70ng
