Transistors

Since Im fairly rusty on electronics I find myself having to lookup these few images alot while building my solar circuit.

Transistor Layout:
2N3904, NPN Transistor



2N3906 PNP Transistor

Nocturnal Solar Engines

I found Nocturnal Solar engines while poking around on the net and I am very very interested in them. I also found out about supercaps which can hold huge amounts of power (1F and up).

So while I dont have any circuits yet, here are the links Im using as references.

Beam Circuits - A fantastic source of info
Interactive Mud - a blog entry detailing his build of the same solar engine I plan to build. Made it alot easier for me to understand the circuit and also he provided a full part list.

Cool Cake

How cool is that cake !!!!!
Found it while looking up a transistor, be sure to checkout the photo gallery.

Made this programmer today, found the link through 8051projects.

Its simple because it does not use a buffer chip, which the 1st one I attempted did. My only issue I had really is I put a transistor in backwards :P

Will upload some snaps later.

Project working :)

Got my project working nicely. I hacked up a xmms plugin and added some comport code (alot of tweaking later) and viola.
Full write up will come later when I find the time.

Quick video below showing it doing its thing to Korn - Dead bodies Everywhere.

Working out why it doesnt work :P

My new thread on 8051 projects

Currently trying to figure out how to calculate the baud rate.

Will post more when I know more.

1st Stage solved, onto second.

Well all I needed todo was connect VCC to V+ and it worked as expected (see forum thread for info). Now Im onto the second stage controlling the leds via a comport interface. Following the 8051projects RS232 tutorial I have knocked up my scheme. Will order parts and continue the fun.
