Final video documentation

Suggestions from critique:

• to paint the frame white not black since it is in a mostly white space. 
• To have more tubing.
• Refine the code better to react to people distances 
• make a less bulky frame. Possibly hang from ceiling if allowed in a different location
• If this project was continued, it was suggested that we use LED strips instead of the tubes.

Improvements we would have like to have:

• Make a less bulky frame
• have frame blend with the enviorment more
• have the tubes straight instead of curled so they do not hang to each other
• make the hanging tube more dense
• Have more motors

Overall, I feel this project was successful. We aimed high and shot a little low, but I believe our concept came across. Other students walking in and out of the library asked multiple times if they could walk through it and were excited when we said yes. That kind of recognition and interaction is what we wanted. Like we explained at the beginning of the semester and during crit, this piece was heavily influenced by Soto's Penetrable. We wanted to provide the same art and observer interaction as Soto does with his piece while giving the artwork itself a response to the observer and in a way, giving it a sense of life.

So last night, we ran into a big problem with our project. It worked how we wanted it to Sunday night, but while doing some little last minuet touch ups to the installation and a final run through test, the code would not up load to the boards. It's really bizarre. We even tried uploading the basic Blink code and it would not work. It kept giving us this same error code:

I googled this error code and everything I found suggested reseting the bootloader and reseting the driver. I tried following tutorials on how to do this, but it is pretty far out of our knowledge and skill base.

We changed every variable we could thing of. We changed usb cables, uploaded from different computers, used a PC instead of our macs, used fresh new arduino boards, and used different codes with the new boards. But I think we have determined it is our code. We figured this out by taking Ivette's arduino board and uploading the simple Blink code to it, and then trying to upload our code and we got this same error code. We have no idea how our code could have gotten corrupted with in the past 24 hours since this is the same code we have been using for weeks. We have looked over our code and retyped it into a fresh sketch window and tried uploading it and it still produces this error. Right now we are trying to update the arduino program, type up the code in a new sketch window, and upload it to a fresh board. We shall see if this works.

UPDATE:  It worked. We had to update the Arduino program on our laptops to the latest version which was just added on the 15th. (What a coincidence.) So we updated it on both of our laptops, and had to retype the code into a new window and resave it and THEN we could upload it to the arduino board. And we also had to use brand new fresh boards. I think the boards that had our old code without the update were corrupted by the code somehow.

Here is a video explaining our project a little more with both sensors and all motors working.

Final Project- The Last Time

Hello reader, 

My name is Tatyana. And I am Kelsey. And we are here to talk to you about our Final Sensors Project. 

At the beginning we were hopeful. Happy even. We had an idea early on, one with both an aesthetic appeal and concept to back it up. Our progress was slow, but quite steady. Week after week, we learned something new, and something difficult; yet we persevered. You can't fathom our joy, nay elation when a code worked, or a motor ran, or a daisy chain was successfully soldered. Or the satisfaction felt when our platform was made, our wood painted, and our permeable assembled. 

AND THEN TO HAVE EVERYTHING COME TOGETHER AND WORK

no words.

So, by now you may be able to understand how confident we were the day before critique: we merely went down to our project, fine tuned some last minute touches, and then turned on its glory.

To find it not to work. 

It doesn't work. AT ALL.

The usb cable, or the Arduino or the serial port are all working together– to not work. 

And we are at a loss for words.

And while we did have a pity party (lasting an hour or so, with only our closest friends), we realized something this morning. Perhaps it's due to the much needed hours of sleep we actually got last night, or the fact that today is the last day of finals, but we realized, that while our project may have failed LITERALLY THE LAST DAY BEFORE WE NEEDED IT, we did in fact still learn something. Actually we learned a lot. We've overcome soo many obstacles (sleep), and thought a lot bigger than we ever thought we could for a sensors class. In all honesty, isn't that the point?

It doesn't work. Yes. But we are ok with that. In fact, we're quite proud.

Thank you for the semester. Happy Holidays.

-K&T.

Process work

Did not work :(  even when plugging the 9 volt to it. We even checked it with a multi meter and it was giving 4 volts which we concluded should be enough for each motor. This circuit only has two motors soldered to it in to save ourselves a little stress and time. The circuit is soldered to hold 12 motors in total

But we took it to a different outlet to see if that was the issue. But I burnt my finger on the board instead.

Progress Work !!!

Process Work 12/12

Consistency is the major problem for this project: regardless of the power source, the motors will run, stop running, and then constantly run regardless of the IR sensor.

Process Work 12/12

I came into the studio early today to look at the circuit again. I connected a multimeter to it and the motors worked perfectly with the sensor just like they did the first time, but only when the multimeter was connected. I tried to get a video of it working but then it stopped just like it stopped working with our laptops. I changed the Hbridge out as well and it still wouldnt power. You can hear the motors try to turn but they dont actually power up. I know its taking too much power and I do not know of any other power source we can use. We may have to drop it down to only four motors if they are really drawing that much power.

12/11 Process Work!!!

Last week we got our frame built. Here are pictures of the process going from my house to the studio.

corgi for scale

 motors being positioned and installed

 one of our biggest problems right now is power supply, so we decided to go with only 12 motors to make configuring the power easier.

 installed in hallway. The peg board will be placed on top of the opened frame when all of the motors and tubes are installed.

 nice and sturdy :D

12/07 Process Work

WENT TO LOWE'S TO GET SUPPLIES:

- wood

- peg board

- tubing 

- fun

process work final project 12/11

We are trying to figure out power supply right now. We had our motors working perfectly but then it shut down my laptop multiple times and now we cannot get them to run from any power source.

For 5v power supply, motors consuming .16 amps, so if we have 12 motors consuming .16 amps each, then we are going to need 2 amps minimum to power the motors.
For 9v it would be 4 amps consumed total.
For 12v it would be 5 amps consumed total.

Final project process work 12/7

Doesn't look like a whole lot right now, but we got the H-bridge working with four DC motors and we got the parameters of our sensor how we want it and the go the three different speed of our motors that we want. All there is left to do now it piece it together and apply it to the interface.
