Today we began learning about microcontrollers.
Sensors:
Analog is range of voltages
Usually 0 to +5V
Digital is true or false
1/0
-5V | 0V | +5V

Today I took a test.
It consisted of basic Unix shell use, network navigation, file navigation, WiFi management and analysis, and IP based sensor da...
Today I started working on my data monitoring, networking, and automation project.
I have decided to utilize the raspberry pi as my platform, becaus...

Today I finished my attack robot.
I attached the servo, but it did not have enough torque to actually move the sc...
The android tablet came in, so I installed my augmented reality holographic interface onto it, so that my program will be still as HPA after I leave....
Today I built upon the background research I conducted, and I planned out the data monitoring, networking, and automation system I am going to build:...
Today I found electrical schematics for the kill-a-watt sensor, and attempted to understand the circuitry.

here is what I ...
I successfully set up the E-Lab PC with my Leap Motion file management program and my Google Glass Holographical human machine interfaces, so that fu...
Today I started building the Xbee reciever for my energy monitoring system.
It will read the 0-5 volt analog data, convert it to digital, and send it...
Today I continued building my receiver node.
I added a buffer chip, so that 0-5V signal turns into 3.3V.

After that, I connected the Xbee R...
today I finished the receiver node and the transmitter node.
I plugged the receiver XBee module into my adaptor, and set the PAN ID, so that they wo...
I found out how to export readable CSV data from the muse headset, so that we can pull data for the sleep apnea prediction device.

Today I finished adding a power supply for the burst transmissions.
I started by soldering a 220microFarad capacitor to the RST pin.
[image]I then ...
Today I connected my transmitter system to the sensor itself.
I put the transmitter node and the capacitor burst power supply inside the case. [image...
Today I successfully got the data to stream across RF.
It turns out that I had soldered the diode backwards, which resulted in a Voltage drop of 5, bu...
Today I found that the fuse on my Kill-a-watt sensor was broken.
[image]Thus, I decided to take a break from soldering, and started working with the...
Today I formatted the SD card, which took up most of the class period, and then copied the raspberry pi operating system onto it. Once I have it runn...
I built a power supply for the transmitter node, so that it could send packets in a burst once every two seconds.
