I want to show you a new interesting project at **broken link removed**
The romanian guys hope to colaborate with somebody to improve the scope!Maybe here is the real place!
attiny2313 parallel programming
What do you mean with parallel programming?He has an AVR Dongle programmer [74HC244] on LPT.He alredy tried at another guy to work on STK 500 board,but the same problem as above!
The all things pointed here are ok!See fig10 in Microchip 00954a.pdf.Is a cllasic aplication,the only thing is to have a good rated zenner,cause,without load,the current is flowing through it!-This means an minimum 1 watt zenner![better 2 watt].The condenser .47uF should be taken at 275 V AC...
reset attiny2313
One of my friends put me a question I couldn't respond-How to reprogram an ATTINY2313,after he made an mistake configuring pin Reset as I/O?Now the controller can't be seen at programming!
Any idea or advice?
Thanks for advice!It's an idea.Mean time I consult my son,he is an software engineer.The gif image is compressed and when resizing it to a smaller one there are a lot of pixels loosed!So the best thing is to redraw in PCB soft and to use with save as .emf ,printing after in Windows Xp tools.
I...
I'm trying to solve a problem-I found an gif image of an PCB[not at 1:1 scale] and have to convert it to an 1:1 scale for printing and then making an iron press PCB.
The harder way can be redesigning the PCB [as painting with an model!...].The other way can be an some kind of importing or...
Re: Current regulator
Take a look to National Semiconductors application AN 178.It has a nice current regulator with LM317 10mA-1.2A.
If you are not depending on LM317 the better solution is a simple Mosfet regulator controlled in gate.
I add a link for a stroboscope which can be found at http://www.mujweb.cz/www/jovv/elektro/proj.htm.
Another good link,as tutorial, is members.misty.com/don/donflash.html .
sab1046
Does anybody have some technical data[like application diagram] for SAB1009[B] and SAB1046[P]?I'm tryng to use this two recovered devices.First is an wide band amplifier and second is an 256 divider.
mosfet high side drive
On internet are a huge number of data and AN.I just put here Motorola old file[Now for application notes you have to visit ONsemiconductors]
digital lcd meter version 1 nokia
I have to show another link for a good AADE based LC meter at **broken link removed**.
It use AT90S2313 as MCU.The etalons are 49 uH and 400 pF.
I build this meter and works well.Comparing to original I don't use the conection with PC.
For some values of...

About FCL Buev has to be remark following diference from typical AADE work[as are presented by Buev]:
-AADE metod has an inconvenient regard to measuring big value of inductors[bigger than 10 mH] with an increasing value of self capacitance.In this case the reading values...
