Hi all!
A couple of weeks ago me and my boss encounterd a problem regarding the control of an audio system my firm is about to install.
The problem was this;
There are four rooms where sound from different sources are to be routed to.
this is done by a remote controller connected to...
issi is61c64 datasheet
Hi all!
I´m looking for a replacement for a 62C64 SRAM.
I found a couple of 61C64 but cant find a datasheet.
Are these chips the same?
Pin config maches.
The chips are by ISSI partnr IS61C64.
Best regards, Hampus
Hi all!
(not shure if this is the right place for this topic...)
I´m trying to make a program in basic that reads the 8bits of the LPT port and
then preforms the Goertzel algorithm on it to get the magnitude of certain frequences.
I havent done anything like this before but thought it might be...
Nice to see that more ppl like thise kinds of machines.
I have found some good info here.
I realy have to lift my hat for this guy!
You can even talk to his computer on the net!
I will post my schematic (if i can find it) with some pictures as soon as I get home.
Thanx for youre help.
Best...
Passive Op-Amp´s?
Hi all!
I have been looking on passive opamps for a little mixer project.
They are supposed to sit in the mic-preamp stage.
Is there any passive op-amp for audio?
If so where and is it worth to use it in a mixer design?
Best regards, Hampus
Hi all!
I´m trying to find info on a little project I have started to get rid of the noise in some cables in my studio.
First I got an passive box (a cheap one) but noticed that it filters some frequences in the sound (mostly the low register)
And dosen´t sound verry good in general.
So I have...
Hi all!
I have a big interest in arithmetic circuts based on TTL and CMOS gate technology.
I´m looking for a book or a homepage about this.
The ones i have found so far lack detailed circut descriptions.
I have built a 8 bit MSEQ with 74181, some latches, and a little memory.
It is realy...
Analouge is very interesting but not the thing that i want to do.
I want to see large circutboards filled with "tincup" transistors.
I forgot to write it before but the plan is to fit it on a wall.
I saw a documenary on TV a couple of years ago about some guys who
built ENIAC (i think) from...
Hi all!
First of all, I´m not shure that this topic fits in here, but I could not find any other
that did, so..
The last couple of weeks i´ve thought about designing digital logic using descrete
components (transistors, resistors etc).
The project, that probably will span eons, is a simple...
uv-proms
Hi all!
Just got some new chips in the mail today! :sm16:
As a bonus the guy i bought them from gave me a pipe of MBM27C64 PROMs!
(realy nice guy!)
The questions are:
1. Can i use my expusurebox for PCBs (UV) to erase PROMs?
2. What kind of programmer do i need?
3. Is the pin out...
