I thought that question was for me, sorry, I didn't mean to answer it for you!
You will be sorry :@
Any idea how I can identify transistors I've ripped out of an old PSU? They have some codes on them but can't seem to match them up to a transistor type,
:-P
No I don't. I'm lucky if I can identify a resistor.
I think it might not be possible. I assume they're manufacturer codes rather than the actual transistor type. One I thought was a transistor (from something else) is a something or other shunt. Also in a TO92 package.
The app I recommended not long ago is useful for working out resistors. By value or by the stripes.
A resistor resists (stuff). So, if you try to do stuff to a thing and it doesn't comply, it's a resistor. I sincerely hope this helps.
Frikkin' colonials, they know diddly frikkin' squit.
That's not the part of a resistor I have trouble with silly! And I don't really have trouble because internet, but it's the silly color stripes that I find annoying.
If you come to a beehive, you gotta expect stripes. Innit?
The RTC arrived today. Soldered some header pins onto it (soooo easy, I thought it would be more difficult doing stuff like that) and got it programmed with the time. Waiting for some other bits to complete the clock.
I did try and get my LCD running with only 3 wires from the Arduino and a shift register but the LCD just sat there blinking it's cursor on the first line so I don't think it did work.
