    arduino vs the rest

    simple things like the joysticks should be ok though right? http://www.ebay.com.au/itm/100-New-JoyStick-Shield-Panen-Controller-Board-Arduino-Open-Source-Projects-/290681883378?pt=AU_Gadgets&hash=item43adfd8af2 I am guessing that lcd''s will be fun to get the right ones though

    arduino vs the rest

    just a quick question. I know arduino has its own comiler. I know raspberry pi has its own too. but what about hardware? could I hook up arduino to rasberry (or any other little computer/microcontroller setup)? and more importantly can i use the arduino compatable parts for other systems too...

    Total noob looking for getting started advice

    i am after a little computer for me to be able to plug things into and program from there. everytime I find something its either really expensive, really dodgy or out of stock. I hope rasberry make a crap load of these soon

    Two-way radio convert to short-range radio?

    just because they are commercialy available does not mean they are not emerncy channels. in certain areas they use the uhf band (walkie talkies use this band too) when there is no cell coverage to call the emergency services. my advice is call up whoever monitors this area of broadcast in...

    Two-way radio convert to short-range radio?

    working with 2 ways i can tell you now they have headsets already. the added bonus is you can modify these really easily as for power they have that too. the only issue is that if you leave the device turned on while connected to mains they get whats called battery memory effect. if you...

    Questions about ac to dc converters

    if you had a model number we could try to determine the power requirements.

    what can you plug up to it? if hyperthetically I wanted something better than arduino for a better project would this work? oh and sorry for hijacking the post for my own evil purposes

    it is advanced. you could start with something like arduino but it has limitations, in fact I highly doubt it will stream video, or even a decent picture. but on the plus side it does get you a start. then there is always the adk boards that allow you to hook it up to an android phone which will...

    How to added up a Resistor Value using misc values

    http://www.1728.org/resistrs.htm there is a calculator there that will show what 2 resistors in parrallel will obtain. if you can do algebra than you can determine the values by rearranging the equation on the top of the page to accommodate your situation. there are multiple answers to get the...

    Adjustable speed motor

    very good observation. I meant all motors speed can be adjusted, and pwm is one way. gear ratio is another

    Adjustable speed motor

    ok leonord just a quicken, an IC is an integrated chip. there are ones that are used for timing. for exmple the 555 timer. you can set these to output a signal every second (pretty precise too) and that will give the stepper motor the signal to move 1 increment. number 2 I may be a vip on the...

    Adjustable speed motor

    I also had an idea regarding keeping the motor speed in check is you could use something very simple like a magnet on the side of a gear and a reed switch, whenever the gear rotates it will close the reed switch. if you use the signal to calculate how fast it SHOULD spin you could adjust speed...

    Adjustable speed motor

    a plug pack would suffice. as coca cola said the easiest way is a stepper motor. to keep it accurate you could simply put an IC in to give digital time an when the second hand or minute ticks over inside the stepper motor will move an increment. this will provide an accurate timer. I would off...

    Adjustable speed motor

    you don't NEED a stepper motor, it is easier that way. but if you goto nearly any basic craft store they will have a cheap clock you can pull apart to get the basic concepts. anyway what sort of power you looking at running it on?
