The custodian was the most concerned about the clock. He wanted me to play with a broken one..... I told him, no, it had to work. 
He's worried we won't be able to tell time at the end. I really don't care, as long as the hands move correctly.  We may add numbers, but I'm thinking we may just leave them all blank.
I walked by the Principals office and told him I'd hijacked a clock and it probably would be destroyed, but would look cool. He just thumbed up the idea.  Quote HistoryQuoted:

Update 2/15
We had a visit from an electrician today. 
We are good to go with our wiring on the shuttle. He asked us to make two changes that were very simple and students have already made those adjustments. He also took a look at our display area and after some climbing around the mezzanine, he found a juncation box he could hook into. We were looking like he'd have to run from much further away, as the lightshuttle are 277volt, but he found the 120 he was looking for right above the windows. I'm waiting for a write up, and then he said they could come in within the next couple weeks or less. It was looking like possibly $500, but now we should be a lot less. My principal said he would split the bill with my Art Dept. The electrician said all he needed was money to pay his guys and the materials. He was a good guy, and thought r he project was pretty cool. |

Update 2/15 continued:
This is one thing the electrician wanted us to change. We had the arduino mounted to plywood. He asked us to mount it to something non flammable as a precaution. 
He also wanted us to increase the size of our "power" wire from 18ga to 14ga. We also shortened it up and brought the junction to the junction box inside the shuttle. 
We were having a bit of trouble today getting the doors to sync up again, but Top Men say they think they know what they are doing. By the end of the day he was much closer, only about 1/8inch from full sync. 
Wyoming flag proudly displayed on the inside door surface. 
Progress on the murals...a short day, so not a whole lot done.

Quote HistoryQuoted:
Compressed air in a can with small straws out the front OMEs would be soooo cool. The students were dreaming about this on Friday.  I hate to give a suggestion with even more utility tie-in but was just thinking maybe one of those ultrasonic humidifier deals could work to make the "fog" as it's just water (so no allergy concerns) but at the same time it would involve a run of small diameter water line (probably don't even want to think about getting approval for that) and the humidity / water condensate that close to the art project is probably a huge risk just from the perspective of physical damage, let alone electrical hazards. Unfortunately the "fog" from the ultrasonic deals tends to just kind of lazily drift downwards (it isn't hot like the chemical Halloween fog machines so there's not much "buoyancy") so it would need a fan to gently blow it out of whatever opening it was shooting from.
ETA: I've been mostly following this from the beginning and being a space flight lover myself, I REALLY wish I had a teacher like you in High School. Closest I had was a wood shop teacher in middle school that let us roll our own model rockets and build trebuchets. Still have M&M dispenser I made in that class on my desk at work. If there's an opportunity to buy one of those patches I'd love to get in on it

They are now working to solve that problem. I'm not sure what he's using for a motor driver board, but there should be a current sense method. Run by majority rule, if one actuator draws far more or less current than the others, shut it down and beep SOS in Morse. |

I could see 2 gyros, but he's going to have problems getting I²C or SPI to run the length of the shuttle. (Those are the two common serial protocols used to communicate with a gyro board to a µC) Same thing as SMBUS on a motherboard and similar to the CAN bus in a car. Two 3D Accelerometers, one on each door, would be sufficient, they'll tell it which way down is and if it is moving or not. That method still doesn't help in a stripped gear situation on an actuator, where the other actuator pulls double current to keep the door moving, however... |

If you make it open and close every hour, you're virtually guaranteeing that you will have problems as it wears IMO. The answer to both the wear and uneven opening problem is to make it open/close via remote command so it can be monitored and stopped if needed. Understandable, and that is why we are looking for a safety. We can replace worn parts if a safety is set up to stop it all when one stops. Just opening on demand would be a pretty big let down. I'm hoping that's not where we end up. As a secondary option, that is cool. |

I'm not sure what "shield" they're using to control the actuators, but you only need 1 pin to toggle open/close and I highly doubt they'll all be in use. If you can figure out which shield they're using I can provide more info. |

Electrical bid came through. $300. Materials are being donated, the 300 is to pay the men to do it. He said he would lower it if it takes less time. Great guy, and very generous of him to help us out like that.
I spent another $40 on black paint today. I thought we'd have enough to get all the way done, but we are just a few square feet short. Some places need another coat too. I'm not going to count the $300 yet, as the principal might cover the whole thing..... $1123 old total + $40 paint and zip ties --------------------------------- $1163 |

That's overcomplicating it. MCP23017 I²C 16 port I/O expander IC is $3 Direct Linky There's probably a pre-built board for arduino using one at sparkfun or something. If he doesn't want to do the I²C expansion (I²C is the most awesome thing since sliced bread for microcontrollers, so he needs to learn it, BTW)... And you DO use Two Arduinos going, I would not not not use one for each door. No matter the case, you'd still need to set up I²C or SPI communication between the two Arduinos so they can cooperate. One Arduino would be the motor control µC, the other would be the timing/input µC. In other words, one Ardunio set up only to move the doors at the speed it is told by the main arduino, which is the timing source, remote control input, motion detector etc. The motor control Arduino would only handle the current sense protection and PWM for the actuators. OR PWM output off of Arduino pins, the rest of the I/O through the I²C port expander. Split it into tasks, rather than sections. "Open and close doors" is a task, "Open left door, open right door" are sections that should be handled by the same bit of code to ensure they are synchronized and all lproblems are isolated to that controller. I hope that makes sense. --ETA: $20 for an I²C Port expander with Analog. Adds 28 Digital I/O, 16 ADC inputs Also... If you are using that type "Shield" that plugs onto the Arduino board for motor controllers, you shouldn't. The motor controllers should be connected with jumper wires so heat isn't concentrated in one spot. |

Update 2/17
Robotics did more testing today. We had both doors working, but we had one motor that needed a little adjusting. We might sneak in tomorrow to spend some time on it again. He has the motors set up in front and rear pairs. For some reason, the rear right motor seems much faster than the other three. We were pretty close at one point but went backwards and ran out of time. We got the new wiring run for a sensor on each door. They haven't decided what sensor they are using yet. The Moon clock with a couple base coats of paint. She started hand painting details over top today. 
The IKON satellite got some nice textures started today. 
The mural group got all of Reagan's speech fragment stenciled on the wall. It took several hours and lots of patience. |

They use I2C for they competition robot.
Thank you for the advice! I'm passing all of this along . |
