It’s Friday, and at i3 Detroit that means it’s Open Shop Friday! This is the perfect time to check out the space, meet some members, work on some projects, or just hang out.
If you’re reading this, you know the deal by now. 1481 Wordsworth, Ferndale. 5:30pm-midnight.
Also, a cookie for whoever comes closest to identifying that thing in the photo…
Do you know what happens when you blow soap bubbles into a cooler full of liquid and gaseous nitrogen? Neither did we, so we found out. It turns out to be pretty cool.
Totally unrelated: This Saturday (9/29), there’ll be a repeat of the “roadside emergency skills for non-greasemonkeys” class, which we’ve run several times. Change a tire, jump a dead battery, that sort of stuff. Please register if you plan to attend.
Speaking of cars: Our Power Wheels car #3 is going to World Maker Faire in NYC! It happens this weekend, so if you happen to be on the east coast as you read this, come say hi!
What’s better than a liquid nitrogen dewar? A liquid nitrogen droid.
Sincerely hoping there’s no regulation against painting these things…
When you’re Yelp, and you’re throwing a big party at the Fillmore, where do you look for entertainment? A bunch of local outfits, including i3 Detroit, of course! We’re bringing the giant Connect Four and beanbag toss (I refuse to call it that other name), and Robot Fight Club, and the Squiggletrike, and maybe even the dangerously fast Power Wheels car #3.
It’s more than just a party, of course: Yelp is raising funds to support a Detroit charity: ”Real Life. My Music. is a nonprofit organization created to provide a musical and artistic outlet to inner city youth in Detroit“. Considering all the education cuts, that sounds like it fills an important gap!
It’s happening this Friday, 9/7. All the details are over at Yelp, and while the shindig is free, you have to RSVP to get in, so just go do that already. Oh, and bring a few bucks for the fundraiser. See you there!
(Can’t make the party but still want to support Real Life. My Music? They’re collecting donations online with Crowdrise, too.)
When Karen (yes, that Karen) decided to host a DIY birthday party, and said that she wanted people to make flowers, my mind went blank. Mario brought casting resin to make plastic flowers, Roger brought color-changing LEDs that got used in a bunch of things. I saw flowers made of yarn, flowers made of vinyl, flowers made of piano keys, flowers made of filter media, flowers made of sheetmetal, flowers made of mylar, and of course, flowers made of Red Bull cans. Still having no ideas, I decided to ignore the party for a bit, and started salvaging some motors from a soon-to-be-recycled CDROM drive.
Then something clicked: At Tuesday’s electronics meetup, we used signal generators and oscilloscopes to display Lissajous curves. With a laser and some mirrors and some motors, I could make Rose curves! Those are flowers, right? Flowers made of light!
The only small mirror available was still much too large, so it got cracked into a bunch of sharp but useful little pieces. With some hot glue, some solder, and a quick trip to the bin of lasers, I had a rudimentary optical path. Joe helped set up a quick-and-dirty pot-and-FET motor speed control (inspired by reading an article about PC PSU testing a few days ago), and with a few more minutes’ work, the whole thing was stuffed into a project box and shooting flowers onto everything within reach, including Karen. Happy Birthday!
