    How to wire up this ssr i have

    You may well find yourself in possession of some gem of wisdom that you can offer sometime in the future. We all started off at the bottom!

    Motor Construction Diagram

    Ever heard of Google? It even has search results based on 'pictures'. You can get some perfect drawings of motor construction by Googling 'electric motor construction' and clicking on the 'images' button - saves trying to draw some dodgy pictures yourself. Strangely (or conveniently) the...

    Leds under rain

    Providing you have the proper protection on the AC mains side (RCD, ELCB etc) the 12V DC side shouldn't be an issue even if it gets wet. Your biggest problem would normally be with corrosion caused by electrolysis but with rain water (the purer the better) this is not usually an issue unless...

    Joystick keyboard

    Joysticks that activate switch contacts are available - they would simplify the need to read an analog voltage and convert. You could also salvage an old standard keyboard and utilise the interface therein. They are all based on an X-Y matrix and easy to decode. I've done this on a number of...

    Difficulty to find components

    In which case you need to adjust your power consumption assessments to reflect the actual usage and you'll find the demands on battery capacity come down considerably. Match that with any power-down/standby function you can implement in software (and hardware) and you'll eventually end up with...

    You haven't got L1 connected.

    How to wire up this ssr i have

    No - you will connect your 12V supply positive to A1 and B1 will go to the LED + terminal. The LED - terminal goes to your supply negative.

    volts, signal and circuits

    There are switched capacitor filters in IC form but proper practise is to use the right part for the job. If a tone control requires a simple RC filter then why use anything more complicated? It only increases expense and complexity if things go wrong. This is the KISS principle. ...or...

    How to make easily powerful RF generator?

    There are very serious consequences for using 'jammers' - your own authorities will come down heavily on you if you do this deliberately.

    Programming A Winbond Chip

    Presumably a multi-function programmer? There will likely be many 'tick boxes' for the chosen device being programmed? Is there anything obvious in the notation beside them? - such as 'overwrite boot sector' or 'disable write protect' etc? You need to know a lot more about both the programmer...

    What are these and do you think its toast

    ...not burned out. They have previously been replaced - badly. The soldering is....... awful.

    Programming A Winbond Chip

    Without knowing (and/or using) your programmer it is not possible to determine if you have set any internal register requirements correctly. You should read the data sheet and compare it to your programmer and its facilities.

    How to make easily powerful RF generator?

    What frequency precisely? What is the purpose? You have to know a few more details before making a request for 'RF waves'.

    Diode Symbol

    Yes it is an LED. Such connectors usually have LEDs built-in to show connectivity.

    Programming A Winbond Chip

    The datasheet for the device is very comprehensive - have you checked it for the necessary parameters for programming etc? http://pdf1.alldatasheet.com/datasheet-pdf/view/231258/WINBOND/W25Q32.html

    Motorcycle alarm kit ~ battery drain

    There is no specification to indicate current consumption. If you have an ammeter (test meter) you could measure the standby current to determine if there is a fault with the device itself.

    Parallel help

    The coils are probably insulated although you might not be able to see it.

    Parallel help

    Interweaving them - without touching - won't change the total circuit resistance (in your example 0.1Ω). Batteries? You are aware of the current such a circuit will draw...???

    Oops.... didn't spot that. Wonder if the OP realises this too?

    Oscillator

    Do you want 'fixed' frequency or variable (programmable)? How accurate? How stable? What frequency? Overtone or fundamental? Sine or square? Logic level or analogue? Temperature controlled? We need to know........ (not really, but this is getting a bit pointless now).
