best firewire oscilloscope
Hello,
We decided to public the sources of the project in the meantime, so now enybody should be able to make changes in the code.
We have also posted some other projects on a new site, www.eosystems.ro , the old web page (that one on the mindbend.ro domain)...
You can also use an 74HC4067, just tie the control lines to the hex keyboard and the input to ground, use pull-up resistors for ouputs, and the selected output will be 0V . Or the other way around (Input to GND and pull-down resistors on outputs).
That works for the HEX to BCD, but i don't...
Re: 3 Channel selector
Why not use an microcontroller, with 3 or 4 inputs for the pedals, and several ouputs (16 - 20) for the switches command ? You can then program several combinations of outputs for an pedal .. that way you can use a single IC and you can have alot of flexibility (you can...
Take a look at this link :
**broken link removed**
It's an serial LCD (data sent through RS232 is displayed on an 16*2 lcd). If you strip off the serial routines you end up with an LCD Interface . Or you can just use the same circuit and test the hole project ...
It;s written in assembler...
I downloaded the pdf file, but i tought that was the project thay you're working on :)) . I don't need docs for controlling LCDs, i have alot of them ....
I changed my profile yesterday so anybody can send me e-mails, so click on the profile button (at the buttom of my message), and then click...
calculator project circuit
Sorry, i ca't see the pdf, not enough points ...
You can send the schematics and program on my e-mail adress and i will take a look, i had several projects with AVR's + LCDs, so i will try to help ...
If you have an 8mhz AVR, it can run from 0 to 8Mhz max, so if...
lcd avr black boxes
hello
the STK500 is a development board for AVR microcontrollers, if you build your own hardware and have an AVR programmer you don't have to use it.
the lcd shows black boxes becouse the LCD chipset is not initialise. Most LCD's use an HD44780 compatible controller, so...
you can also connect a reset circuit ...
try to take an final project as a reference, there are lots of designs on the web about connecting a 2-line lcd to an atmel controller. Look for example at **broken link removed**
It should be preety easy to adapt an working design ...
Re: s-video to usb
You can also buy an USB TV tuner with s-video input, it should cost 50-6o Euros.
Depends on what you want to do with it ... if you just want to trnasfer some frames from an old vcr , a TV Tuner should be ok ...

Re: use ur old computer CDdrive to enjoy audio CDs in your
The noise comes from the potential difference between the CDRom and the power amplifier. The current consumption of the CDRom generates an potential difference between the ground connection of the CDRom and amplifier (the cdrom...
