HP/Agilent 16700A 16702A Logic Analyzer Modification
The HP16700x series of logic analyzers are known for being
picky regarding keyboard and mouse attached.
Below is a simple modification which allows the analyzer
running with almost any PS/2 keyboard and mouse. Tektronix TDS 220 Maximum Synchronization FrequencyIt is almost unbelievable but the maximum frequency the TDS220 100MHz oscilloscope synchronizes to is 186 MHz. Amplitude of the signal shown is significantly lowered, of course. Published 25.4.2005 OrCAD Tutorials
I have discovered a nice set of OrCAD tutorials. For those who don't know, OrCAD is a CAD system for electronic
design. All designs at vanka.net were created with this powerful CAD. MC34063A Switching Regulator Experience
Some time ago when I was looking for a suitable power supply for
our relay board, my eye stopped on MC34063A switching regulator.
The MC34063A is considered rather an obsolete part however what makes it really interesting is its price.
For less than $1 you get complete +5V/0.5A switching power supply controller and
the only thing that you need to do in order to build a step down converter is to add a coil,
diode, three resistors and three capacitors. And this is exactly what I did. NetPrint - Debug Over Ethernet
Every designer needs sooner or later to know, what is going on inside
the device he is designing. The simplest possibility
which can be used on almost every microcontroller is outputting the debug information over
one of its serial lines. But what to do if all of them are busy? AVR JTAG MICRO ICE MINI HOWTO
AVR JTAG MICRO ICE is a device used to program and debug Atmel's
AVR microcontrollers with built in JTAG interface (typically all ATmegas 16 and up).
It is very useful for rapid application development - it is like
a microscope which can be used for viewing what is going on
inside a microcontroller. Variables watching, stepping,
breakpoints, all of this speeds up development cycle,
especially when something goes the way we don't expect. |
