    HELP

    There's a lot you'd need to know about your project as a whole before approaching it seriously.  What power standard do they run on?  Duty cycles, wattage, average use, availability of space to deploy solar panels, available space for battery storage bank, local regulations, etc, etc, etc.

    LCD Manipulation (Help Required)

    If we are discussing a text message on a cellphone, wouldn't it make more sense to have it forwarded to a PC and processed through software?

    microwave crucible

    There is a variety of information concerning inductive crucibles available on the net.  A very basic cup and heating element might be constructed, but it is likely more affordable to simply purchase a refurbished one from a used tools supplier.  I'm all for building it yourself, but you have to...

    Help Please

    Set a goal, then go about figuring out how to achieve it.  At the very least browse the internet for topics that interest you and see if something doesn't inspire you.

    Electronic Gun !!!!!!!!!

    [i would not encourage children to develop high tech weaponry and would firmly discourage them from using them on themselves or others.]  I saw a project online once that took a page from the XREF taser shotgun rounds, concept.  It used pressurized air to propel a charged disposable camera...

    Electronic suppliers

    I've run into the same problem.  Their search functions are largely useless, thumbnails are largley nonexistant and the language they use is impenetrable.  I've been having trouble finding a simple pair of round 2 conductor plugs on any of the major suppliers.  If you like variety and ease of...

    how to program a microcontreller ?

    There's a zillion different MCUs out there and they are programmed in nearly as many ways.  Some require expensive hardware/software bundles, while others are free, open source and connect easily via SUB/Serial/Ethernet.  Which one are you trying to work with?

    How to integrate the wireless cam?

    Scoot on over to www.instructables.com.  I recall reading several different projects that dealt with this and should help.

    pain feild generator

    These names remind me of an old book I checked out from the library some years ago, simply because I found the title amusing.  Something along the line of "Build your own laser, ray gun, phaser."  I believe it was from the 70s and featured designs with similar names.  I think the most...

    Hyperdimensional Resonator

    Maybe if he accelerates to 85mph while doing that it will help?  ;D

    Electro Magnetic Pulse

    At one time law enforcement was going to deploy these disc launchers under their cruisers.  The disc was fired under a suspects vehicle and used a powerful microwave frequency burst to toast the vehicle's onboard electronics to shut it down.  Or was it radio frequency?  Been many years.  I don't...

    (job offer)Build me a simple wearable tool using a compass and some vibra-motors

    I know of a number of effective compass modules.  As to vibrating motors, I think a simple display would be more accurate, effective and efficient.  There are numerous ways this could be accomplished.  I see the post is somewhat dated, so I wonder if the request is still active?

    Power Supply for capacitor bank

    I appreciate you reformatting the image to a more suitable file format so that it will be of more help to others reading our ongoing discussion.  How would you modify the circuit to use that portion of the LM393 as you propose?  I was unaware this was possible.  Also, since the bank is now a...

    Power Plugs

    No, there isn't a requirement on pressure to remove.  Functionally the male plug holds the ignitor that fits up inside the rocket motor.  The female side fits to a modular power board which controls the power distribution and which rockets fire.  This operation is usually performed on a very...

    Power Plugs

    The parts will be in the tube where the rocket motor is fired.  The male side will hold the ignitor and is intended to be reloadable.  While the female side is part of the launching fixture.  These are small rocket motors.  The outer diameter of the assembled rockets will be between 0.75" and...

    Power Plugs

    Not that it makes much difference, but it is for remotely launching model rockets.  The data I've looked at so far says you need about 9-12V @ 1A to make the electric ignitors work correctly.  And I've found a convenient, safe way to do it.  Trying to find parts to fit the bill.  Any other...

    Power Supply for capacitor bank

    The attached picture is of the diagram I am lableling pertaining to the modifications I am making so far.  It is incomplete.  I am still translating and adjusting.  I have to give credit to the design's author rwilsford, who shared it.  I have been cross referencing with other open and basic...

    Power Supply for capacitor bank

    I have a circuit diagram that I've been working off of to modify to meet my requirements.  Would that be helpful to post as far as discerning things?

    Power Plugs

    Been trying to work on a prototype for a simpler project that needs a couple of power plugs.  Looking for plugs rated 9-12V @ 1A.  Round preferable.  One is to connect to either a backplane and could be flanged to screw on, or be surface mount to PCB; I prefer this to be female.  The other comes...
