By that formula, for an R of 10k + 10k pot for tuning + 1k pot for fine tuning, C is roughly 0.022uF. Thanks.
Hi there. I'm trying to use a PIC 16F84A in RC timing mode. I'm using RC rather than a crystal mode because I need a very low input frequency of...
http://www.interq.or.jp/japan/se-inoue/e_ckt17.htm Did you mean this?
How do you generate a sawtooth wave?
Hi there... Firstly, it's been a long time since this thread was around, back before the faceleft, I believe. Talk about necromancy......
Having a seperate reset for the alarm and the light probably isn't that difficult, you'll need to make a latching circuit (some sort of Flip-Flop,...
In the electronics magazine that I used to read, they used 10pF for the crystal in nearly every PIC circuit. So you'll probably want RA33 on the...
I can't understand how those 2 work. I can understand how mine works, though... Although I did manage to find a better picture of the circuit,...
I looked a while ago, so I know that idea is correct. I'm just worried about things that I haven't considered...
First of all, Hi, I haven't been here in ages... Secondly, I'm planning to create an interface circuit, so I can connect my old Amiga joysticks...
Why not just use a PIC? I'm sure that it can be done in about 30 lines of code...
Generally, I use a 0.080" pad size, a 0.050" track width, and a 1mm drill bit. However, some things require a bigger hole (pots spring immediately...
Smelling it will usually tell you, especially if freshly blown...
I think that a 4016 would work here :idea: , but I don't know if it is suitable for high loads... :worried: LA Greg
10mm LEDs are generally the same as normal size ones...
t = R x C x 1.25(ish) Where R = resistor value in k and C = capacitor value in uF giving t = Time in ms
Thanks... Ok. so you're running it at 12 volts... Well, the outputs are the LEDs that you wanted... except that you can't run them directly...
Ok... The 4017 is what was commonly refered to by a teacher friend of mine as a "light chaser chip" and it does kinda what it says on the tin....
I know that It wouldn't be as impressive, but why not drop down to 8x8x8? All the numbers add up. With the size reduces to 8, the number of...
You're probably looking at finding a way to modify the control voltage pin of a 555...
