looks like UnrealEd supports OS X now.

very interesting...

if i wanted to buy a AY-3-8910 off the internet, how can i reduce my chances of buying a fake chinese knockoff?

all real game developers already use windows/linux toolchains, so all osx support means is more terrible amateur games, probably about slenderman

the chinese knockoffs generally do work. whether they last 20 years of 24/7 use is another thing, but i guess it depends what you want it for. otherwise a lot of the new-old stock chips are real 8910s with the registers at different addresses that were made for OEMs back in the day. if you're modifying/writing your own software then these are perfectly fine.

otherwise the yamaha clones like the YM2149F seem to be easier to find

righto - electronics
so ive got this led driver ( led+driver ) to power. its minimum voltage is 8v. ive got an arduino. its also got a couple of fans ( fan ) to run. ive got an lcd sheild with a few buttons so in a later revision of this ill be using that so how to pin out while that shield is on is a different challenge but im not there yet

the fans are video card coooler fans so i think they are 12v but they seem to work fine with 5 or so


so im wondering in general the best course of action for powering this from mains


as far as i know the arduino cant handle da current to power these things directly
so i need a power supply that can power the fans, led driver and the arduino.
if i get a 12v power supply i foresee that i can plug this directly to aruidno amiright? then use bipolar transistors (i dont have any mosfets and poo poo loads of trannys) for switching the fan and the led driver, both of which can take 12v


i doubt i will be using many amps. powersupply are those kinds of pwoer supplies ok? i cna connect them to mains power huh (240v)

i appreciate you helpin my noobness



e: alternatively i could use something like this http://www.fasttech.com/products/0/10000007/1147900-4-channel-ac-dc-relay-module for switching and be lazy

yeah those PSus are what you need

be lazy. thats what you need to get here. you could roll your own but you'd end up building that board, basically

what are you trying to make?

electronics scares me and i don't want to blow up another arduino

i have a 5V output pin, a 3-terminal normally open microswitch, and an input pin

how do i wire it so i can detect that the switch is closed?

I also have 3 more microswitches and a parallel to serial encoder but i'm not quite there yet

Jonny 290 posted:

two connections to the arduino pin:

+V to the pin through a 10k resistor or something close
wire to one side of the switch


connect the other side of the switch to ground. set it as an input pin. if it's high the switch is open, if it's low the switch is closed

how did u explode an arduino anyway

Sagebrush posted:

wire the microswitch between ground and the input pin

in your arduino code do this

code:

#define SWITCH whatever

void setup() {
  pinMode(SWITCH, INPUT);
  digitalWrite(SWITCH, HIGH);
}

void loop() {
  if (digitalRead(SWITCH) == LOW) {
    //do a thing cause the switch is closed
  }

}

this sets the pin as an input but also sets the internal pull-up resistor on it so it stays high by default and doesn't float. closing the switch brings it low. this is the proper way of reading switches (at least it's more common than using a pull-down and putting vcc on the switch)

shorted something in wiring and melted the atmega and a shift register

since then i've been spending a lot of time writing an in-band command set for this lcd shield i have or basically anything not involving wires

i can program the thing in C just fine, it's electricity that scares me
