Learning Curve and Fast Conditioning Applied for EECS:
I think that adding arts & crafts elements to my lesson plan may add the orthogonal dimension my class needs to really expand the imagination of our kids. I could probably finally utilize the hundreds of pachinkos in my closet for marble type games.
Some of my new friends from Galileo @ Tech Museum are really smart! I will be asking them questions about a bunch of things!
There is an interesting recursive algorithm that a student suggested during lunch about how he finally figured out how to create a sin wave using an excel spreadsheet (no joke, those were his exact words). The algorithm is as follows:
- Make a row of repeating pattern of 1,1,1,1,0,0,0,0,-1,-1,-1,-1,0,0,0,0,… etc (basically a square wave, make it as long as you want).
- Afterwards, set the first element of the second column equal to 0 (for a sin wave) and for the remaining rows in the second column use the template in the second entry
- Do the same thing for the third column, but subtract the amplitude of the previous column.
Today just started messing with the I-racer, will likely try to interface it directly with my computer. I need to find the app for my android phone — once I do I may try to code for it via another program (I think this is called using their program as a service?).
The other devices which arrived include a sparky thing (insert pic here), some diffuse led’s (another pic), and an IOIO — which I am very excited about programming for!
I was wondering if it is possible maybe to use the android sound input as a portable oscilloscope? If it is this may solve the problem discussed in a previous post about needing something that could take high frequency samples of a voltage divider. Updates to come.
