Simple Circuit Design for Red LED
I am looking for a electrical engineer who is competent, prompt, and responsive. I've worked with a couple engineers on here who haven't fully satisfied my expectations.
All I am asking for is a regular communication and a decent turn around time. If this project goes well i will likely have several projects for you. If I send you an email, a response within 24 hours isn't out of the question, in my opinion. I'm not expecting you to drop everything to work on this, but regular updates are a must so we get this moving along and I'm aware of issues, etc.
This should be a fairly easy project. I will need you to make a sample for me and I will pay for the parts and to have it shipped to me (DO NOT include the parts or shipping in your quote).
I will also need support with responses to questions I have about certain aspect of this as I am an accountant, not an electrical engineer.
I will need a circuit of two (or three if the battery life will be long enough) red LEDs to light up. I will need one mode to be completely lit and the other to be flashing. I bought a compact little "adventure light" that is capable of performing both of these modes just by switching the way you use two Lithium CR2032 batteries. If possible I would like it to run on a two or three hour timer. The battery life will need to be at least 200 hours in the flashing mode.
It will need to fit inside of 10mm x 30mm x 30mm casing. If it won't fit in that, the 10mm dimension can be bumped up to 15.
I prefer someone in the U.S. so that I don't pay a fortune for shipping the parts to you and getting the final product from you.
Here is a link to the product I am referring to. https://www.youtube.com/watch?v=b0Gkm_oYBxU
I will want the product to be similar in terms of how it works; however, I may want to use an on/off switch rather than just turning the top to turn it on.
I want the lights to flash about this speed...maybe a little slower but not much. https://www.youtube.com/watch?v=F6S0qif2C1w
The major concern for me is battery life. I do want it to obviously light up well, but not as bright as the light you see in the first youtube link...notice how the light is very bright (almost like a laser pointer). However, it doesn't light up the entire device, just the very middle where the LED is. I want the entire thing to light up and the LED's will not have to be anywhere near as bright as the ones in the first youtube video. As long as the light are visable from about 50 feet. So bright to a degree but not like a laser pointer to the extent that you have to look away if its directly in your eye.
