An RF tracker can do what you are looking for. Here is a link to a **broken link removed**. (Stalk much?)
You can code your robot to act more intelligent to be able to find the source with 1 receiver (this would not be triangulation in the real sense), or use 2 receivers placed apart to...
I did not measure the positive load current. Negative output had no load when I measured. The 9V is a LM7809 regulated power supply - I used the standard circuitry with bypass capacitor right before feeding the circuit-, not a battery. Maybe this due to no load?
I thought the problem may be...
All modern worthless pop singers are reaping what autotune offers to their sound engineers.
Plus, a recent research that I read says that young population has adopted to liking richer treble than quality bass. (Go go Ipod Earphones)
Hello all,
I posted a representative schematic of my shot at 555 negative voltage generator. The problem is the lowest value I can get is around -8.2 V, in time it rises close to 0V - defeating the whole purpose.
How should redesign to make this unstable power supply work properly?
It won't be an easy project as Torben mentioned. Google for guitar effects schematics for pitch shifter, octave shifter, cry baby, wah-wah or wah pedals. These effects won't make you sound "female" but will make a blurrier, higher frequency replicate of your voice.
What language are you programming in? How many outputs are you driving the display with? Are you programming a PIC?
Post the code you have developed so far. At least show some effort to explain your problem to get accurate help for your assignment.
That circuit is an adjustable amplifier, not an active filter. LM35 output is probably not going to go high enough to drive PIC input. You should amplify so that highest expected temperature reading is close to 5V and lowest is close to 0V - given that you are powering your PIC with +5V and...
Yeah you can produce 2nd harmonic of your fundamental frequency but you can not reproduce the guitar sound like that. Your produced output will sound more like a siren as all sine waves do.
Are you looking for an octave shifter, wah or phase shifter? I had found a zip of all guitar effect...
I think I found one of my college lab assignments on the web. Here is a walkthrough sheet which will help you design a single cycle processor. You can find referenced files in the pdf's directory.
For a more complex assignment we had designed a multi cycle processor, later on a pipeline...
Simple Multi-Function Generator
By changing the last stage -2X amp to amplifier of your choice you can vary the output voltage.
I'm not sure how to vary the current output though, other than by changing the generated frequency.
