Motor Driver Demos

For driving a DC motor via relays it was tricky reading which gates would actually be enabled when looking at the manual however it was straightforward after that. The Transistor Relay was easy to set up however I was not able to operate it properly.  My understanding of the Transistor was that it is a circuit with a semi conductor that only becomes conductive when that material is polarized. For whatever reason the conductor circuit would operate regardless of whether or not it was polarized. I rechecked the diagram as well as some online guides on the proper positioning of the transistor pins as well I manually tried reorganizing the pins if I somehow got the circuit wrong. I think my issue was either my power supply was causing issues or I misunderstood the use of the Transistor, I was able to get some pulses whenever the transistor was supposed to be set off so I think I misunderstood the use of the Transistor. The TIP122 controller was pretty easy and straightforward, ...

Kinetic Artwork Research

For this project we were referenced two artists, Rebecca Horn and Arthur Ganson. What immediately struck me in Horn's work was how visceral it was specifically how it pushed the external in internals of the figure outwards to the point of grotesque. Some examples were a tube net with blood pumping through it (blegh) or big constructs of fabric constricting and hanging off of nude figures. Her sculptures also get the same treatment with pianos splays it's own keys out and shotguns that splurt blood. Arthur Ganson I have seen before, I attempted to construct a wire machine similar to him however mine turned out more a tangled mess but with a functioning axle. His sculptures have a delicate precision to them and he shows he's constructed his own tools and templates which he uses to build his gears and wheels to precision. His machines play with expression and function with his oil machines dousing themselves and his movement machine which hand writes "faster". I wo...

Circuit Board Designs

For my starting circuit designs I went forward with making them applicable to my projects going forward. I'm not sure how to properly setup external power supplies for larger outputs so that's likely to change however the designs are intended to work regardless. This first design  is intended to work with Piezo buzzer discs for receiving a signal, I am using the digital pins for power in case I ever want to use this design for an audio output. There are two potentiometers, one for adjusting the sensitivity of the discs for input and the other is for adjusting the LED intensity for the output. I've used the button to bridge over the ground for the potentiometers and the LED power.  This circuit is for powering multiple parallel LED strips with a joystick, I have the same potentiometer for adjusting LED intensity as well I had to use jumper cables to bridge all the grounds for the LED. Not much difference aside from the 5 points for the Joystick. Working Joystic...
