Microgreens: Automation

Wed, 15 Jun 2022 20:01:00 +0000

This was an experiment to create an aeroponics microgreens grow. The idea is to use a silicon or stainless steel mesh with holes small enough to keep the seeds from falling through. Then a top is a placed on to act as a weight (pushing the roots down) and to keep the water that is sprayed through nozzles (every 15 minutes for 1 minute) from escaping.

It was successful for the first couple of runs, and was very easy to harvest (no coco coir, or other medium to clean off) and easy to scrub the grow plate off afterward.

Nanoleaf: On the cheap

The design was all done in OnShape and then printed out on my Prusa MK3s+ using a wood filament type. The intention was to use magnets to connect the lights together, and then stain the wood to give a unique light.

The white plexiglass didn’t cascade/black enough of light though and you could easily see the location of each LED.

An early thought was to try using some nickel ribbon to create pressured tabs that would connect (sort of like your AA’s connect the negative in your remotes) when snapping together. Finding the right length, proved difficult though, and I just wired them through the holes for prototype 1.

The Box: Parametric Modeling

Mon, 20 Jul 2020 20:31:00 +0000

This was my first real introduction to parametric modeling with OnShape. My previous experience with 3D modeling had all been with standard game development.

This build had a whole host of features.

NFC tag reading on the top
Integrated 3W speakers
Bluetooth connection through Raspberry Pi
7" Touchscreen
Integrated night light in the base
Integrated wireless charging in the base (just slide your phone in)
Electron App based desktop/website with weather and full customizable
Fully 3D printed enclosure with very little empty space remaining
