Who are you?

A ham I am. General class working toward Extra. Having just relocated, in process of setting up ham shack. Major interest is in QRP radio circuitry and related, e.g., power supplies, etc.
 
well i think this is the right place, enjoying the challenge again of fixing electronic equipment, currently learning smt soldering for phone repairs, televisions and things, keeps me going for hours and hours :)
 
I'm a playwright who knows nothing about electricity but who is writing a play about Tesla.
Sounds like a train wreck ready to happen, right? Agreed. I apologize for what will be seen to be my vast ignorance.

My first question, from the position of abysmal ignorance, is: "Do electric particles flow through wires, or is the flow of electricity through a wire more like the flow of energy through the ocean that creates wave crests and troughs? In other words, is matter actually going from here to there through wires, or is it something else?"

Hello Everyone,

My name is Laura and I'm a student Mechanical Engineering, but I also want to learn more about electronics. Thus far, I've done (very) simple projects, so my skill level is still Newbie. But I'm looking forward to do more.

I am a high school engineering technology teacher who used to be a construction electrician (journeyman wireman to those like me).
I encourage my students to use this site quite a bit as they courses in DC/AC electronics, analog electronics, digital electronics, PLC and robotics to complete in the two year program.
 
Briefly tell who you are. :p

I'm a senior student studying EE at UC Berkeley, specifically analog circuit design. B)
I have a B.S. in electronics, I enjoy circuit analysis, I worked at one time in physics engineering and then worked in R&D and was involved in the testing of RS-232 communication systems and load cell testing for retail weight scales. I have also 10 years of experience writing low level software using assembly language and C/C++. Over the last 21 years, I worked in the I.T. field writing programs that regression tested other applications and are currently a Software Developer working on mission and non mission critical software projects. I am very creative and I like to share my ideas with others across all sciences without putting people down. I can offer help with circuit analysis to others.
 
Hi, all.

I'm a retired electrical engineer, but humbly come seeking the help of experts. My main electronic project now is trying to build a solar-powered bicycle. Many people have built solar-charged bicycles, but I would like to build a bike that will run, albeit slowly, without batteries. The plan is to tow a huge solar panel on wheels behind the bike, and have a power controller that tracks the maximum power point on the solar panel, a buck boost configuration with equalized voltage charging through synchronous rectifiers for a supercapacitor bank.

Very happily married, two children, living in Northern California.

Welcome to AAC.

That's an interesting project. Now that you have introduced yourself, post your project ideas on the project forum.
