Update with the TO-220 package

Few weeks ago I posted a request to the forum asking for help in using the non-standard spacing of the TO-220 package for a National Instruments H-bridge: http://www.servomagazine.com/forum/viewtopic.php?t=4853 The consensus of the forum was that as there were no adaptors, the best option would be t...

Thank you all for your suggestions. Soldering the wires and then, maybe, building the board seems the best way to go.

Thanks again,

Help with TO-220 package

I want to experiment with an Integrated Circuit made by National that comes in a 11-lead TO-220 Power package. That is basically two rows of pins, each one separated 0.067 inches. I would like to use a typical breadboard, so obviously it does not work. Do you guys have any suggestions other than sol...

Recommendations for SMD work

Although I have done some SMD soldering, this has been only minor devices on a board with the majority of the components being DIP or similar. I would like to purchase a station for SMD work, mostly for hobbist projects.<p>After checking all the different websites, and reading as much as I could abo...

Re: Presence Detector

Philba: Thanks for the information and the links. The first schematic, the one based on the capacitive plate is similar to what I need.<p>However, I don't really understand how it works. The two inverters -on the left side- are configured as an oscillator that will produce a square wave. How does th...

Presence Detector

I am interested in developing a sort of a non-contact human presence indicator, a system that will produce a binary output only (presence/not present). <p>I have winding a wire to form a coil on a specific area and hoping that the presence of a person in that area will change the inductance. I belie...

PIC Programming

Not that many people care, but I just needed to share with y'all that last night I programmed by first PIC and ... it did work! This is more important to be because I have always been a hardcore analog guy. Granted, it was just a "test" program, but still...<p>What really matters to me is that diggi...

Re: electronics knowlege at BSEE level

I teach both, Electrical Engineering and Electrical Engineering Technology at a large university (that used to have a winning football team).<p>The BSEE program that we teach is highly theoretical with very abstract concepts, lots of high-level math and a minimum of hands on experience.<p>The BSEET ...
