Final project proposal

So for my final project, I want to build a series of relay circuits to trigger old tube television functions---mainly the charge and discharge of the cathode ray gun, and the anode charge of the tube itself (this is essentially a fancy way of saying turning the TV on and off at a specific rate).  This might sound like non-sense, so here are some videos to clarify (note: the light of the TV's is quite bright and is not represented well through video recording---it is supposed to be a live visual experience)>


Each TV utilizes a different placement of various types of magnets to accent/manipulate the charge/discharge of the tube (some magnets hidden, some magnets exposed).  For the final project, Im guessing (hoping) to have about 6 TV's finished for this.

The relay circuits will be designed using Max msp, then loaded onto the arduino, then that data will be transferred onto ATiny chips, then those circuits will be hidden within the TV casing.

Why do I want to use relays instead of transistors?  I like the physicality of the switch in relays, I like hearing it and I feel like keeping that 'click' sound makes sense in terms of this project----when the cathode ray gun charges/discharges it makes a very nice, but also sort of dangerous sounding sweeping tone (these are all pretty old TV's) and it is paired well with the 'click' of the relay:  "click-bweeeyoo"  ...   "click-boowop" ...  etc.

So here is the first thing (program?  not sure what it would be called) I made as a test of my memory for max msp.  It is just a sequence of flashing buttons.  I just used exactly what we learned in class, multiplied it by... i don't even know---x100 or so?

I was trying to make a series of triangle waves that would link up to make diagonal lines.  Not a complete success, but not a total failure.  Good for a first attempt.  Then I gave up to start working on televisions for our final projects (next post).

so here are some photos and a video of the max msp setup:



 no matter how close I moved the buttons together, I couldn't get rid of that white line, unless I overlapped the buttons quite a bit (which cut into the circles... no good!).
