Saturday at 10Bit

Progress on Ken R.'s 10BitBot.
Just after this photo we installed the MDF (Medium-density fiberboard) plate that carries the heated bed.
What remains is a base board, electronics, power supply, GT2 pulleys and belts, and a tangle of wires. A session or two more then on to calibration. Ken S. was unable to join us last night with his build. It will be nice to take a picture of the sibling printers together.
Andy, any news about your teams build?

Johnny Garcia came into 10Bit during Siclovia, 2 weeks ago. He’s a Multimedia Journalist https://www.facebook.com/SALiveJohnny from KSAT / SALive looking for a story on 3D printed Fiesta Pins. It hadn’t occurred to any of us at 10Bit to make a Fiesta Pin, but, hey, we’re a Maker Space, how hard could it be? Matt Grooms and Jeremy Zunker smelled publicity and pushed us. Don Smeller took the bait, resurrected an old Kinect scan of a work colleague’s face, James Martinez, and 3D printed a yellow Nobel Prize knockoff. That was last Saturday. On Wednesday 4 days ago, after the RPNA meeting, we robbed a ribbon drape from councilwoman Shirley Gonzalez’s pin and, voila, we had an entry for the pin derby. But, no way was that going to be quickly reproducible. We brainstormed a bit on the corner of the table, literally. The idea at the time was to make physical models that could, in turn, be cast in aluminum. James went to SolidWorks and his home 3D printer and made the red model shown, front and back. Don went in a different direction, to Inkscape vector graphics and the laser cutter, and executed the blue model with deeply engraved letters in 1/4” acrylic. Saturday, in real time, in front of Johnny’s cameras, on the sidewalk, James made the sand castings and poured one of each. Inject some red and blue paint in the low spots of the gray aluminum. Needle nose pliers, wire links, scrounged red-white-and-blue ribbon drapes. TA DA! Not exactly gold-plated jewelry grade, still they look pretty darned good. Did anyone take a picture? Noooo. Would someone amongst the Sunday crowd please snap a picture and send it out? By 5 pm Saturday, James and Don sat on 10Bit stools in front of Johnny’s bright lights and were interviewed wearing their respective aluminum metals. Then Matt had the good sense to go back a step and simply array of laser etched model and cut it out of 1/8” acrylic. Duh. We called it done. You can pick up a pin at the kiosk. The TV piece will air in 2 weeks. We’ll let you know when.

Johnny, Don, James, Matt, Jeremy:They add up to only 5 people at 10Bit on Saturday. There were 19 others:6. Carl visited from Tucson. Despite having a lot of maker space history, he had never heard of it, but he left with a brand new hacker-space passport. His first stamp: San Antonio, TX.7. Sacha and8. Mary came in to use the table saw to rip laminate floor boards. They’re remodeling an old house nearby.9. James V zoomed in, scraped the over-night-printed parts off the MakerBot’s bed, and zoomed out to compete in a quadcopter race at Roosevelt Library.10. Oscar called and then came by looking to laser cut some rectangular holes in 1/8” acrylic. It’s some kind of domino based card game.11. Kevin gave Oscar a hand. BTW, Hey Kevin. I found a rounded-corner-rectangle feature in Inkscape. You’ll need this to minimize stress concentrations.

Johnny, Don, James, Matt, Jeremy:
They add up to only 5 people at 10Bit on Saturday. There were 19 others:
6. Carl visited from Tucson. Despite having a lot of maker space history, he had never heard of it, but he left with a brand new hacker-space passport. His first stamp: San Antonio, TX.
7. Sacha and
8. Mary came in to use the table saw to rip laminate floor boards. They’re remodeling an old house nearby.
9. James V zoomed in, scraped the over-night-printed parts off the MakerBot’s bed, and zoomed out to compete in a quadcopter race at Roosevelt Library.
10. Oscar called and then came by looking to laser cut some rectangular holes in 1/8” acrylic. It’s some kind of domino based card game.
11. Kevin gave Oscar a hand. BTW, Hey Kevin. I found a rounded-corner-rectangle feature in Inkscape. You’ll need this to minimize stress concentrations.
12. Sue added capacitive touch switches to her LED circle clock.
13. Joe discovered the new-to-10Bit mill that will cut traces in circuit boards. He was big time enthused. He also brought his friend
14. Pearl to the space for the nickel tour and a laser demo.
15. Randy introduced me to Cliff.
16. Cliff Etheridge has one arm. He has an idea for a fishing reel with a motor-driven winder, controlled by a thumb switch. We brainstormed a bit. We can do this, but we’re going to need some motor expertise. Cliff wants to fight BIG fish with heavy test line, but, at the same time, he wants to reel his trophy in FAST. I can do the drive train and the mechanical hitch-em-ups. Is there a volunteer to help with spec’ing the motor for Cliff?
A gaggle of people crowded around the table in the studio playing a board game called “Agricola”:
17. Selena
18. Greg
19. Chris
20. Keith
21. Craig
22. Mike G
23. Ray showed up with a work work project. His oscilloscope captured 10 million pressure transducer points in 2 seconds along with the PWM on/off signals to the solenoid that causes the pressure profile. He has written a parser program that grabs only 1 point in 400 and ignores the other 399. The program also displays the abbreviated data as an Excel chart vs time. The result looks like a heart monitor.
24. Ken R did another session of building his 3D Printer. His is the son of the RayGoodBot, and the grandson of the 10BitBot Ken’s is oh so close to completion.
