Important Sites

Here is a link I stumbled across a few weeks back. MIT Open Courseware
Its a link to MIT's open course ware. They have some really interesting open courses. I downloaded a tone of them. Finding the time to do them however remains to be found.

Pure Data

As part of my degree I have opted to explore the Program Pure Data. My first patch is nothing special it makes laser sounds and the "Wheel of Fortune" wheel blip sound. Oh that Bob Barker. Of course you have to adjust the sliders and number boxs to get the sound just right.

So I have spent some more time completing the VCO for my synth. The main problem was finding a replacement for a chip which was poorly labeled in the schematic. TSM101 to be exact. I will post the final circuit once I am sure this whole thing is going to work. It would be a shame to see all that hard work waist away, but until i make a power supply for this board I am unable to test it out. Here are the updated pictures with 100% population of the board. The next stage is to add the mixer for complex wave shapes. I am not overly concerned about that at this point in time. My focus is going to be the power supply however until I find voltage regulators for + / - in all required voltages I am putting that on hold.
