I just got my first picaxe 08M chip with a USB cable and the programing project board. Didn't come with much of anything else.
I managed to program it to the very simple timer sequence I want.
Now I just need to sort out what other parts I need to finish making the timer circuit I want.
I think I can find all the parts for the power supply side of things.
Challenge I'm having is finding the transistors for the output side of things since radio shack here in the USA apparently doesn't carry the BCX38B like listed in the manual.
I will be using a 12 volt relay to switch the mains power (unless I come across something that would operate on a lower voltage closer to what the control circuit needs but still be able to handle switching up to 3-4 amps of 120 volt mains power.)
Can anyone share with me tips for figuring out what alternative components would be appropriate in this situation.
As I said, I'm starting out very very simple. I'll be turning on and off a small pump on a 5 minute schedule (as in 5 minutes on, 5 minutes off, repeating.)
I've gotten the chip on the programing board to turn the red led on and off according to the schedule I want.
I've got some power supplies and I picked up a voltage regulator and I think I have the rest of the parts (caps) to handle the power input side of things.
I've got an assortment of relays and can easily find more.
I have diodes and resistors
I just don't know much about transistors. (my earliest tinkering with electronics has been with 555 timers which can handle enough power not to need the transistors between it and the relay.
There are some transistors in the junk box. What do I need to know to figure out if any of the ones I have on had will suite my purposes?
I've got some TIP102G and TIP107, are they of any use to me or should I save them for the original project they are meant for? I can go to Skycraft to find more parts but I need to have some options since they are a surplus place and don't always have "everything" but they generally have lots of different things.
Thanks

Be gentle, I'm not all that well versed in electronics lingo (I'm a stagehand/audio engineer for corporate meetings by profession which means I probably won't kill my self when handling electricity but I don't want to fry the chip I'm playing with either.)
