    Thanks to you all. I'll break out the crayons and Scotch.

    Programming starting point

    A very general question. When you have come to the point in a project where you need to write code, how do you begin. By that I mean do you start by using pencil and paper or do you dive straight in with a software package like flow code? For the younger members of the forum, pencils and paper...

    Wanted: Transistor Circuit Techniques Book

    Where books are involved I always start with archive.org. I typed in transistor for text files and got 265,697 hits, ranging from patents to NASA documents and everything in between. All in the public domain so no copyright issues and all free to download. Worth a look

    IGBT current limit

    I still haven't mastered posting circuit diagrams but my circuit is simple and easy to describe. The purpose is to limit the current through a 1.58mH ignition coil to 4 amps. The coil is driven by a Fairchild IGBT specifically used for ignition coils so all the spike suppression is already on...

    Can a person determine the Bands used on a given cell tower,

    You could start here and find out who is licensed, then use the license info to find their allocated frequency. http://wireless2.fcc.gov/UlsApp/AsrSearch/asrRegistrationSearch.jsp

    Lightweight Electronic Spark Ignition for 2 cylinder engine

    So the ASE classes I took to get my Master Certification were all wrong? Going to ask for a refund.

    Lightweight Electronic Spark Ignition for 2 cylinder engine

    That's going to make starting damn near impossible. Every time the piston is rising on the compression stroke the spark will fire and never let the piston get to TDC.

    Lightweight Electronic Spark Ignition for 2 cylinder engine

    On a side note how would the ignition timing work? I see from the instructions that they set the timing to about 30 degrees BTDC so I'm assuming that the circuitry will detect the pulse from the hall sensor and using the time between pulses will either give a long delay at low revs to set the...

    Where could I find a low RPM high torque motor?

    Maybe start with one of these, a hacksaw and a welding torch http://www.harborfreight.com/automotive-motorcycle/winches.html

    Good Resource For Learning Bjt Transistors And Amplifier

    Makes you wonder how electronics have come so far so quickly when everything that is taught in schools is wrong. You would think it would have all been corrected by now.

    Good Resource For Learning Bjt Transistors And Amplifier

    At the risk of again being told that the information is wrong I recommend you check out an internet site which links all the library's that offer free, non copyrighted publications, by that I mean books. For the younger members books are like videos, but with pages instead :p i did a search...

    Good Resource For Learning Bjt Transistors And Amplifier

    I'm sorry I was only trying to help and honestly though that as the video came from a lecture given by Professor Jerzy Wrobel the professor of physics at the University of Missouri, I assumed it to be accurate.

    smart home innovations

    I was about to ask "Why reinvent the wheel?" but then thought why not break down the question and show that it's not practical to do it yourself. Start with a few questions. The infra red sensor, would this be passive i.e detect body heat/movement or static like a magic eye beam interrupt? If...

    Looking to get into Atmel programming, few questions...

    Atmel Studio 7 is a free download from Atmel. It's very bloated but I do like it's debug simulator. Add to this a simple kit (search for Atmega8 kit on the bay of all things, about $2), a few Atmega8 chips ($1 each) and a USBAsp ISP ($1.75) not only will you get a complete starter kit for about...

    Seeking Knowledge!!

    Unless you can match Intel who have spent $11.7 billion in R&D so far this year I'd set my sights a lot lower.

    Looking to get into Atmel programming, few questions...

    Nobody has suggested looking at the Arduino platform, which is odd as it's cheap and a good introduction to programming, and the Uno uses the Atmega328P MCU, which has enough power for just about anything. Yes the Arduino IDE has some faults but it's dead easy to learn and you can integrate...
