Well, I found out that I matched for Residency in Neurology. What a relief. I am also in the process of getting a house. Yeah, it is true that the fourth year of medical school is much easier than the earlier years, but there is stress, and time consuming things of another [...]
I have done several posts from the Cornell University electrical engineering senior design site. Here is a robot that follows sound. It sounds like a really cool project. It apparently has three microphones, and a microprocessor detects which microphone is receiving the strongest signal. It will then turn the robot to [...]
Things have been kind of crazy here lately, and finally I have gotten some breathing room. I passed step 2 of my boards, and have realized how much I miss writing for DIY Live. I have not forgotten about it. I have plans of writing some here very soon.

Alen from hackedgadgets.com wrote about this laser listener device. A microphone is simply a diaphragm that vibrates with sound waves. The theory behind this device is that when people are talking in a room, the window will vibrate. If you shine a laser on the window, it will bounce off with the [...]

It is absolutely amazing the number and variety of computing devices that have been created and obsolesced in just 40 years. Integrated circuits are used for many purposes, but these pages focus primarily on vintage computing chips from the 60's-80's.
PIC & Electronic Development on a Shoestring

World's first transistor Dec. 16, 1947, three physicists at Bell Laboratories in Murray Hill, N.J., built the world's first transistor. William Shockley, John Bardeen and William Brattain had been looking for a semiconductor amplifier to take the place of the vacuum tubes that made radios and other electronics so impossibly bulky, hot and power hungry. They were so instantly certain they'd found their answer that they didn't speak a word of it to anyone for six months, until they could experiment further and apply for patents. Then on June 30, 1948, they held a press conference in New York City. They showed the world not only a big model of a transistor but also a TV and a radio with transistors in place of the tubes. Nobody was talking about anything like computers yet, but it was a first look at the future we all live in. The world's response? The New York Times ran an item at the bottom of its "News of Radio" column on page 46. |

HOW TO WIRE-WRAP Wire wrapping is a means for making connections between circuit components using 30g Kynar wire wrap wire and a special wrap tool. The tool forms the wire in a tight spiral around the 0.025 inch square wire post. The post must be square in cross-section because the corners of the square dig into the wire to form a gas-tight connection.

Understanding electricity (water analogy) Beginner overview of electricity, using the water analogy... What do
you think? Electricity seems very difficult for most people to understand. You can't properly see it, you can't properly feel it and you can't taste it or smell it so what is it? It travels quite well through metals and generally poorly through non-metals. It doesn't behave quite like anything else. But this is not quite true: fluid flowing through a system of pipes can behave in many respects like electricity flowing in a circuit. The 'obvious' exception to this is that if you pierce a pipe full of water, the water comes out. Try piercing the insulation and touching the conductor: you will soon find the electricity coming out! The main difference is that water will fill any space whereas electricity will 'fill' only a conductor. Yes - the analogy is not perfect, but it is helpful and understanding will come not only from the similarities but also from the differences. 4QD-TEC: Electronics Circuits Reference Archive.
