3d Printer Part 7

-
Welp, I ordered the Arduino Atmega 2560 which I got for $10.59 and the RAMPS shield with 5 motor drivers for $18.04. I will now wait as fast as I can until they get here from China.

I believe my plan for now is to make it work with crappy printer motors until I can upgrade them to NEMA 17s like the plans call for. I might order the heated bed today too.

The circuits I made above drive the motor at 5 volts which is not enough to run the motor at full power and speed, but I was being conservative as I'm not really electrically inclined either beyond basic circuits and digital design.

Also, I have discovered in my reading, the traversing bed is the y axis not the x axis.

I found one of my Teac motors from a 5 1/4 floppy drive and know I have at least 2 more- Weee! Also, I remembered I have 4 micro-controllers I could have used to simplify my design- 3 TI Launchpads and a coriduimcorp microcontroller! The reason that is easier is that rather than wiring 2 gates with 6 wires each and hour's work and testing, the logic can be obtained through coding with just a few keystrokes. I was glad I did it the hard way at least once though. That'll give me something to do till China sends me my shiz.

Too bad I don't have any darlington arrays laying around(aside from on that scanner control board that is) My 10 o'clock is right near OEM Parts so I may find myself accidentally shopping for good stuff on the morrow...

Click Bait Using Logan Paul's Name and Face

It's not really clickbait since I am commenting on him. I want you to look long and hard into his face and think about what you see. Before the trending tile on my tablet directed the browser to his apology video, I had never read or heard his name. I watched a few seconds of it and didn't see anything of value to me. As in, I was bored. My first impression told me he had a weird looking long face and his hair was stupid.  I know that is shallow and of no consequence so I gave it not another thought.  Over the next few weeks, more an more things about him touched my consciousness and I watched a video made by a former friend of his. Later, I was shocked to learn he earned a million dollars a month making outrageous videos popular with preteens. I didn't watch any of his videos and still haven't. This is my opinion- he's nothing; empty. He gettin pizzaid to be nothing.

Fate of the Furious Ending Scene

I was watching the ending scene where everyone is hanging out of the rooftop. As the camera pulled away from the actors I noticed something strange. The focal length of the camera was changed as the camera pulled away.  I decided to figure out where that was. I knew it was in New York City somewhere because of the establishing shots. After watching the sweeping shots in and out of the picnic scene and looking for visual clues, I found it: 767 10th Ave, New York, NY 10019  It's the building wherein resides Sonny's Groceries.   I wish I would have captured some images from the DVD but the library wanted it back. Before that, however, I matched up my view from Google Earth to fit the frame as best matches it in the movie.  You will have to watch it yourself to see how well I did. The whole city is a CG model and that rooftop is a fiction. Also, the tall building behind the one in the scene was made much shorter or removed altogether so the twin Clinto
