Third year at engineering, awesome girlfriend, new spanking website and possible through hole plating!
My website has be redesigned with the help of my girlfriend who has been helping me with the wordings and style. Ok I lie, she pretty much did everything I just coded the darn thing. It...
Stepper Motor Forward And Reverse Testing circuit.
Using NE555,CD4017 and ULN2003 to build a stepper motor testing circuit with forward and reverse.
NE555 - astable circuit with adjustable frequency.
CD4017 - Decade Counter/Divider with 10 Decoded Outputs, using it to strobe the ULN2003...
The Internal Structure of NE555 and Application Circuits.
I've been at uni for more than five months now.
Not once have I seen a soldering iron.
I've used a breadboard twice though.
This is engineering, not theoretical electron management. :P
So, here's the thing.
Got coursework due in on Friday.
Lots of work set, really too much set to do during the time allotted each week (seriously, not typical student excuse).
So here I am. Not too much to do now. Mainly organising it. What good is a tidy logbook? Logbooks should be...
Toroidal Inductor
An inductor constructed by placing a winding on a core that was a donut shapes surface, toroidal coirs are available in many magnetic core materials with in the four basic types: ferrite,powered iron, alloy and high flux and tape wound,characteristics of toroidal inductors...
Distributed capacitance
In the construction of an inductor, each turn of wire or conductor acts as a capacitor plate, the combined effects of each turn can be represented as a single capacitance knows as the distributed capacitance,this capacitance is in parallel with the inductor, this parallel...
Impedance
The impedance of an inductor is the total resistance to the flow of current, including the AC and DC component, the DC component of the impedance is simply the DC resistance of the winding, the AC component of the impedance includes the inductor reactance, the following formula...
These displays are available for only $14.98
Discount available if you buy more than one.
If you are interested, I can assemble the PCBs, and put them on eBay for your purchase. Simply pay with paypal, and the transaction is recorded with ebay.
3-wire serial interface
low voltage operation...
Now you can even buy korean noodles from my ebay if you really wanted to.
It is more expensive than buying them in a local shop- but maybe there is no local shop with korean noodles on offer.

We got started in Python with simple assignment statements and the print statement in the last entry.
In this one, we'll examine the some Python innards and its type system.
Let us examine how Python converts your code into a machine-readable form.
In languages like C or C++, it is the...
For all of high school C++ was my favorite language for writing general applications - probably because of the similarity to C and my laziness to try and learn an entirely new language.
For some reason, I didn't get to do a whole lot of C++ in college because of an EE major. I tried playing...

I will add more content soon such as various old C compilers, and ebooks about Windows programming.
These ebooks are from dated books which are no longer sold and no longer relevant for mainstream commercial programming.
These downloads are designed to use...
The recommended first step in starting out on this project is to make sure that you will be able to successfully compile and run your program once you've written it. This has proven to be a bit of a challenge for some because of a few of subtle points regarding the tools. So hopefully this...
Nand2Tetris is the name of a project that is the focus of the text The Elements of Computing Systems: Building a Modern Computer from First Principles by Noam Nisan and Shimon Schocken (2008 MIT Press, ISBN 978-0-262-64068-8).
The book is extremely affordable -- when I last looked it was $28...
Introduction and Scope
Diodes, specifically p-n junction diodes, are a commonly used device in all manner of electronic circuits. These range from being used as very high power rectifiers dealing with hundreds (or thousands) of volts and/or amps to detecting the information signal in an AM...
There is a widespread -- and not too unreasonable -- misconception that a battery is basically a charged capacitor that has a reservior of net positive charge on one side and a reservior of net negative charge on the other side.
Somewhat related to this misconception is a difficulty in...
1Hz time base - using CD4060,CD4013, 32768 hz crystal.
I used this circuit for a long time.
