EXPO!

The day of judgement arrived at last. We were relieved and happy to see our composter running successfully. Thanks to all the judges who were able to make it to the expo and question/comment our product.

And a huge Thank You! to Bob, Doug, Mohamed, Clarissa, and Alex for their constant and willing help throughout the entire design process.

Here it is!

DONE!

TH4L, duh.

Sugru Part IV

So soapy water definitely works with Sugru. Our final attempt came out really well!

Final Expo Prep

The final two days before the May 7th Expo got more than a little crazy. All hands were on deck for many of the final 48 hours of prep. A brief list of what went down:

1. LCD screen suddenly became too dim so we bought a new one, which required a new front for the unit and some rewiring.

2. After we figured out that our AC motor wasn't beefy enough, we tried some more powerful ones before ultimately opting for a hand-crank to turn the compost. In the end it was a much more energy efficient solution and looked great.

3. The bioreactor's inside ended up being too crowded with propellers and stationary screws – we took the whole rig apart last minute and got it back together, functioning much more smoothly than before!

4. We played some sweet tunes (sorry to everyone else in the shop) and things got pretty weird.

Final Weekend of Composter Prep

...and Susan is at it again. Congratulations to our 400m hurdler, breaking 60 seconds for the first time with a 59.85 at the Ivy League conference championship. That's her out in front:

In-house Demo: Check!

We had the sensors working and the blades spinning (and a sweet front display), warranting the ULTIMATE complement from Bob: "Sweet Man!" We were flattered, to say the least.

How much Sugru goes into a seal?

In-house Demo Today / One Week To Go!

With just less than a week left until the design expo (Tuesday May 7, 1-4 PM), we are finishing up the coding/electronics for our sensors and we will begin testing the composter TODAY!

Here are some pictures of how things are looking:

The Past Week

Here's some of our progress from the past week, which featured plenty of good work in the shop (fueled by some freaky music, i.e., Die Antwoord – shout out to zef side):

Bioreactor propellers installed:

Heating pad installed (orange strip) and bioreactor coated with insulation tape:

Bioreactor taped, sealed and ready to go:

Team Update

The composter is nearing completion! We've been doing a lot of odds and ends this week like...

caulking holes

installing the moisture sensor

installing the carbon filter

mocking up the electronics organization

There's still a bit to do but we're shooting to have everything completed soon. We had a set back with the 2nd Sugru mold but everything else is coming along.

Sugru Pt. III

We learned the hard way that oil does not work with Sugru. Unfortunately the 2nd seal didn't work out.

Sugru Seal Pt. II

After 24 hours, we took off the mold. Unfortunately the bond between the Sugru and acrylic wasn't strong enough for taking off the mold but we are experimenting with some different glues to use for placing it on the acrylic.
