A lot more work on your end Ron than I anticipated. I'm learning a lot from this thread on how electrical engineers create and design electronic machines. I didn't know about computer simulation of circuit design for instance.
I've been keeping my colleagues and PI's informed on what I'm...
Looks great! Will it work? My eyes aren't all that great. :D
Looks like a lot of work. How are your eyes?''
No, seriously, I do see the 3 timers. I assume this will be powered by a 15 volt 200 mAmp power supply and there will be 2 output terminals one for the valve and one for the coil...
No the job is not taken. The more ideas on how to design a controller that closely mimics how e-cigarette users use their products the better.
This machine will allow for researchers studying e-cigarettes to evaluate the health risks involved with inhaling heated glycerol, propylene glycol...
I'll see if I can put together a document detailing what we've been discussing. tangible requirements being the timing specifications and voltage requirements? I'm not sure what you mean by an analysis document though.
I'm in San Francisco California.
I am getting close to retirement age but I'm having too much fun at work. It is satisfying when something goes from an idea to an actual device that works and does what it's supposed to do.
Can you put together a parts list?
You know the best vendors. The prices look low. If the price is less than $60 I can order the parts and probably get reimbursed off of our grant. You of course would have to put it together. While I love electronics and like tinkering with computers and mass spectrometers there is no way...
So I can set the controller to have a 1.8 second delay, a 4 second puff time and 16 seconds between puff for 1.8 + 4 + 16 = 21.8 second cycle time. I can then run this program for 1, 2, 4, 8, 16. 32, or 64 cycles. 16 cycles would take 16*21.8 = 348.8 seconds
I could have a program that would...
I started out with a solenoid button pusher that slips over the battery and pushes the button on the battery just like a person would. The battery was a black box. There was no way to know how much power and voltage was being delivered. That's why I came up with the power supply. I...
The relay is what switches the power from the power supply to the coil. The relay receives the same 4-second 15 volt pulse that opens the 3 way valve to apply vacuum to the e-cigarette. The PS is wired through the relay. When the solenoid in the relay receives the 4 second pulse it closes the...
We have quite a few of the 510 batteries and tank model clearomizers models. I believe the standard rechargeable batter is 3.7 volts. The coils range from sub Ohm to 2 ohms or so. Is yours a top or bottom coil?
I'm not sure I get what you're saying. E-Cigarettes are almost always used with batteries. Some of the batteries can be quite sophisticated with variable voltage and power selection as well as puff counters. While my machine which can and does work with Ego type batteries I prefer to use a...
