wireless keyboard encoder
Hello All. I'm trying to make a custom wireless interface for a video game I'm making. I'm familiar with using a keyboard encoder, but I wouldn't know how to make one wireless. Does anyone know of a

clock help was counting ic's
I got myself a 555 timer but im not shure how to get it down to 1hz or 60hz to base the clock if somone could help me with finding the values for the 2 resistros and the capacitor the ic I am using

lm2907 F to V question
Has anyone used one of these? I am using it as a tachometer and using an induction coil for my sensor. My question is the on the 8 pin version of this IC the pins are tied to ground through a resistor

Anyone have an idea if this exists?
Hi, I'm looking for an electric solenoid (I think that what they're called: a cylindrical device that has a piston which pushes when actuated) that is no bigger than 2" in diameter and about 6" height

Re: Shift-register and synchronous counters
But can you please elaborate more? You see I am new in this world of electronics and unfortunately I have to ask people like yourself to get all the answers. Another question: How can a ring counter

Re: Slowing down voltage
Hi JOn, I have a LM317 in TO220 package that I intend to build a 1.5 - 35v / 1.5amps variable regulated power supply for testing my hobby electronic circuits. The transformer is 230AC50~/32-0-32v

Re: Slowing down voltage
Hi, First - a little more information - at what amperage (current) do you need this voltage? It's reasonably important. There are a couple of ways you can do it, either with a LM317 positive voltage

Re: counting ic's
OOPS...... I just looked back at the chip you're using, and see it's output table is drawn with the least significant bit on the left,so 0101 or LHLH would be right for 10(base10). Though that's a bit

Re: counting ic's
That's the easy bit - just feed the 60Hz into the clock, then count up to binary 10 (divide by 10), and feed binary bits used to make 10 (0101), into the inputs of a dual-input AND gate IC, and feed
