    Hello and is this the right place?

    If you can spring for it, I would use overall braid shield, I would not think you should have that much problem if shield is grounded, what frequency is any radio using. I'm assuming the 24v is referenced/connected to the tank frame? M.

    24v Keypad - Microcontroller

    To follow up it appears that the keyswitches are anything up to 24vdc rated, the diode anode/cathode is 5v, I am assuming that there is internal series resistors, it does not mention the inner connections. M.

    Hello and is this the right place?

    Those were after my time, militarily speaking, but all our mobile radio equipment was shielded. M.

    24v Keypad - Microcontroller

    As long as you observe the 50ma rating. Correction, I see they have a ilumination LED they mention 5v for these? Separate connections. M.

    Hi and pic question!

    See my post #3 these are in assembly but In one forum someone has converted them to C. M.

    24v Keypad - Microcontroller

    Those KB's are passive devices, just tactile switch so 5v or 24v does not really matter, they are set up with a matrix to save on I/O, see the tutor series by Nigel Goodwin Tutorial site. M.

    Electronic timer motor

    Still very little info, but an easy off the shelf solution is a timer such as Irrigation/sprinkler or a Automotive block heater timer, both cheap and are RTC timers. M.

    Help me draw this circuit's diagram

    They exist on ebay for $5.00 based around the 555 and PWM control or see http://www.discovercircuits.com/DJ-Circuits/simplepwm2.htm M.

    Help me draw this circuit's diagram

    You don't neccesarily need to know how it works if you accurately reverse engineer it this entails drawing out a schematic by very carefully following every connection. Post what you have here and it can be looked over and checked. There does not seem that many components. M.

    Single phase to three phase motor

    That's about a 4hp motor, any reason for wanting the 3ph conversion? M.

    Electronic timer motor

    Do you need a real time clock or just a time period on? There are DIY electronic means or off the shelf timer etc, there is a lack of data to go any further! M.

    Stupid question

    If you are talking of the small kink in the end of the leads, I think that is to retain them in the board until after soldering. In any case I just use needle nose and crimp them straight.! They are usually a tad wide to get into a Breadboard anyway? M.

    PIC programming

    Download the MPLB IDE and obtain a Pic programmer and off you go. Rafts of information on the Picmicro site, including code examples. BTW you appear to have hijacked this thread. M.

    Power consumption of vibratory pump when pumping against closed valve

    It appears to be a simple pulsating piston pump, if the coil is DC then there should be no difference in current, in AC the current would vary if the piston had not moved over due to reduced inductance. If it were an impeller pump the current would reduce regardless when the outlet were blocked. M.

    Questions about UART communication

    It is not a practice I adhere to, I usually use a common, I was just quoting the instructions with many devices and systems come with. M.

    It's a logic level gate so it should work. M.

    Questions about UART communication

    Differential is using two lines that are 180° apart so each logic common is not, or need not, be connected. I have used the UART in Picmicro but usually RS232 TX/RX. M.
