Binary to BCD conversion.
Hello Everyone, By searching this forum, I encountered this subject. The file was sent by KLM on april 2011. He promised to send more info, which I haven't seen so far. When I studied the circuit, it seems very chaotic to me, maybe he had no all the possibilties, which we have nowadays. Well, one th...

Re: Alarm System
Dave, I managed in making the same circuit in nearly real IC's (pin layout is correct). It took me a few evenings (nights) to accomplish this. I upload the new file right away. I worked on the whole thing since last sunday. It's nice to know something about you. I've figured out that we must have ab...

Re: Alarm System
Dave,
I've replaced the file by a more sophisticated version.
Let me know, if you succeeded in downloading the file
regards
Hans

Re: Alarm System
Hello FF-Dave, I, for myself, would just suggest this solution before. But I thought, you had already made, built, the circuits. Instead of a multiplexed system, I would propose a system with registers. As input, you can take a Serial/Parallel-IN to Serial OUT register. Take care of the inputs, for ...

Re: Alarm System
Hi FF-Dave I assume, that you use the 74xx-family, because I've seen that you're using a 5 Volt supply. I think that a transistor is the best solution. If you use it in GES-configuration, that is: You can use every NPN-transistor 1. you have to connect the base,(with a resistor) to the output of you...

program velocity
A little introduction Hello I'm Hans Cadans. I've chosen this as my nickname, because I love playing the drums. Beside this, I also like making electronic circuits, especially digital concepts. Furthermore I wrote many programs in basic, assembler, C++ I've made, just for fun, a similar program, lik...

A little introduction. I've choosen my nickname Hans Cadans, because I love playin' the drums. Besides this I like designing digital circuits and I also wrote many programs (assembler, C++, basic) For example I've written a program in EXCEL, which simulates counters, shiftregisters and LED's I hope,...
