#3DxRobotics – Andrew Terranova’s EconoSpazzi #3DThursday #3DRobotics
Inspired by Marek Michalowski‘s Spazzi, Andrew Terranova’s (aptly named) EconoSpazzi offers quite the (music-reactive-head-)bang for the buck! As with many of the robots that he designs, this one is shared on the site he co-runs, Let’s Make Robots!
Here’s what Erin shared about EconoSpazzi: “Fun intro robot, and you can get a bit of personality from the 3 solenoids!”
While I was filming Make: Live episode 12 with Becky Stern and Matt Richardson, I saw they had a Beatbots Spazzi. I love those things. Becky was really nice and gave me a set of the Makerbot printer parts. I was really stoked to make one.
However, when I looked up the other parts I would need, I saw that the solenoids they were specifying on the Makezine.com website were $18 each. That’s too much for my wallet.
I knew a source for a similar solenoid for only $1.50 each. Thus, econoSpazzi was born.
Here’s the site for the original Spazzi project on Makezine.com. I bought my solenoids from allelectronics.com (update: No longer available last I checked). They are rated for 24V DC, but I found that after I cut the included spring to size, they worked fine at 10-12V DC.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
