Raspberry C64 Pi Computer

Running A Raspberry Pi 4 in a C64 case with fully functional keyboard and USB hub.

I integrated a Raspberry Pi 4 into a Commodore C64 Maxi case. The Pi uses the integrated keyboard and the USB hub. An integrated power supply provides power to both, the Pi and the C64, which now run in parallel. The Raspberry Pi boots from an internal SSD drive, turning this machine into a full desktop computer that can also run Retro Pi for true retro gaming.

Emmet’s Full Size Dream House

In the LEGO Movie 2, Emmet is inviting Lucy to his dream house. Similar to a Tardis, it is bigger on the inside than from the outside. But when we get to see the backside of the house, it becomes clear that there is a full size version that is different from the set 70831. I too several screenshots and tried to assemble this full size version of Emmets house based on the shots from its rear side.

The house can be opened up by removing half of the roof and by opening up the other half. We have the famous couch and the double decker porch swing. Here are some screen grabs from the movie and their MOC counterpart.

LEGO Digital Crawler with EV3 Controlled Gear Box

This LEGO remote controlled crawler uses a sequential gearbox from Sariel and a Mindstorms EV3 to control the car. The remote control used force feedback and offers proportional control over speed and direction. It also allows you to change gears and change the forward and backward drive. The two EV3 Mindstorms communicate using Bluetooth. The remote uses two rotation sensors to measure speed and direction.

The building instructions are available for LEGO Digital Designer and Stud.io. Please notice that I had to replace the 35188 Technic Changeover Rotary Catch with another gear in the digital model and I could also not include Mindsensors Glide Wheel Rotation Sensor. These bricks do not yet exist in digital form. I also put up the model are ReBrickable and the inventory there is almost complete. Feel free to also use different wheels. In the LDD model I also had to use other shocks.

Here is a video that explains the model’s function:

And here is the crawler in action:

 

 

Race3 Extreme Offroad Car

I built a new version of my Race cars series (Race1, Race2) with the logical name Race3. This time I am using the SBrick to control the car which gives its proportional steering control. This is great for driving curves. Race3 features individual suspension, ball bearings and a very low centre of gravity. You can drive it up and down pretty much any rock or mountain. Here is a video of what it can do.

And here are some photos of the model. Building instructions are also available. I also put up this MOC over at Rebrickable.
