    How do i know how many volts my circuit needs?

    My guitar electronics didn't put out anything... dead. I think its because the baxandall circuit requires alot of power.

    Old Style Op Amp

    back in the days of pc boards and splices... When the circuit required an operational amplifier, you stuck a transistor in parallel with the base and collector and that was it. so I am buttoning up my new monster guitar. I don't know how I got it all on that one little chip... Or how I am...

    Jazzmaster style bullet strat guitar cavity

    phase switching, series-parallel or what ever is really becoming a pain in the cavity--- imagine my present dilemna of 2-6 contact ON-ON switches 1-5 way switch with 7 contacts(most have 8 contacts) a master volume of 3 contacts, a master tone of 3 contacts, and 3-2 coil pickups with 5 wires...

    Coil direction deduction

    Suppose I wanted to know what direction a coil of wire is wrapped(just trying to follow the code of electronics) what would be a good way to find out whether they were wrapped right? Is there a way? What would the product be if I connected them wrong? Why am I sitting here wondering all this...

    Tone for thought..

    I Started a new guitar kit for xmas. It is listed as a Jazzmaster style kit. I am building a rhythm jazz guitar. It has a strat style pickup configuration, and so I am really excited about my electronics options! I got my hands on 3 single sized humbuckers, and the switches I need for complete...

    Chips and PN junctions

    Is there a way to make a cathode driven driver for LED segments, operate an anode driven set of LED segments? (whooo whoo!!) I would like to say no... and go another direction, honest! How about an np|pn junction? I have heard something about these, but never considered it an advanced state...

    Type of sensor for project

    I don't know... have you ever tried to finish a chicken(death blow, slit troat)? Early this year I attempted to build a guiloteen with a thick machette and an x shaped frame that forced the neck and head into a rather compromising position...It failed badly and I feel horrible... The feathers on...

    incompatible arduino components

    I got an cheap arduino kit for fun and to extend my electronics knowledge from a good working state to a hack and slay state... I decided to build components rather than devices... well the kit has a lot of potential as pieces parts for larger projects... so I started with commonly available and...

    Multimeter reading of LED

    The measurement is of forward voltage drop, right? and the setting on the multimeter is the diode setting, it doesn't read the diode backwards right? OK so when you test an LED and it says 1730 and you are supposed to be figuring out the proper resistor to use so you don't burn out the...

    Why I don't like wall warts

    I think this is one of those check the specs of the wart online and then buy the right one questions but.... Why can't I read the 2a that the wart is supposed to be delivering? I metered it and it just fluctuates between 0 and 0.8a? 12.29v .08a out of a 12v 2a wart

    this is not a chat site...

    I guess I got used to the IRC rooms where everyone talks about nothing at the same time. anyway... I have another one of my vague questions... How smart (how much electronics would someone need to know) to create a custom ECM for a motorcycle that was not designed for one, with OBD interface...

    Flourescent light balast...LOA

    Lights of America produces all kinds of lights... UV, flourescent, party lights, and they are fairly cheep. Now here is why. The transformers sit on each end of the bulb. between each transformer and the powerline is a set of these... a 750k resistor and a 15.93nf capacitor. this is what they...

    Adding accessories to component systems

    motorcycle accessories are all the rave.... so here is my final workup on the overpower tail light problem I have created for myself... Alternator puts out 14v 20amps @ 5000rpm to charge a 12v/20ah battery if I run an accessory of 5 - 27.5w bulbs, which totals to 137.5watts My alternator puts...

    Getting Signal Voltage From Source Power

    I used to know how to make this conversion from source power ie. 12v to signal voltage, but I have forgotten what signal is. its like 1 ohm at 1v or something like that... can anyone help me?(ha ha ha)

    Ohms law chart from radioshack.. vs ..home made ohms chart

    I got myself an electronics encyclopedia from Radio Shack. It had Ohms law in it... pic looked like this- I was having so much trouble decifering the fancy code box that I tried my own version... pic looked like this- Well my trouble was the wheel in which the law was originally drawn.... like...

    volts, signal and circuits

    I find there is a chip for just about anything... and if you are working with a special set of stuff, there is often a chipset just for that.... If I am working with volts and amps and ohms, just raw electricity, does this include chips and chipsets? or are these signal only, and am I wrong...

    Arduino Aggregates Eprom Prob

    now here is what I am trying to do... except... I used the tools I was given to learn with... heh heh! I explain then... an digital led driver chip powers a 4 digit 7 segment display+DP, but recieves its signal through a modular RTC real time clock, all the leds are powered by the arduinos...

    sad device - no support - no fix

    A gift to me... A USB "versa drive" external hard drive. This device roars up to abut 7200rpm(I think its a 5400 device) with a whirring buzz that shakes the earth foundations in the desk.... Then it just is a do nothing app, and no drive appears in the drive list, and the entire thing was a...
