SHIPPING UPDATE OCT 7: Receive item at office of exchange in Destination Country

Hi Vamoose, I was actually starting to get worried due to my previous experiments that the idea of using a D&L technique to a SE to maintain optimum performance wasn’t going to pan out due to a non-bell shaped RPM –v- Power curve. Well this is now all long gone due to some published performance ...

Hi Vamoose, What you proposed is essentially what I have been doing this past week, measuring what my small little JS002 toy SE and the DVD spindle motor can produce in speed and power. I did approximately 20 runs and plotted 20 different RPM/Power curves. Similar trends, but all different data. So ...

MPPT Oct 3, 2012 Got a simple bracket mounted to the JS002 Toy SE to hold the spindle motor from the DVD player to the flywheel. Stretched butyl inner tube sections over the JS002 flywheel and spindle motor disk to form a gravity pinch roller. After some finagling, I got it to even illuminate a LED ...

also J, i am really interested for you to get your engine. I'm sure your going to test the hell out of it.... Thanks Vamoose for the encouragement! I wonder if we can get the VMPPT done before it arrives. If so, it will be abused upon arrival... ;-) Built up a resistive heater to test watts in - sp...

Found this while doing some googling, not sure but it looks like it could have some helpful info for this discussion. It's about a free piston control sytem: http://www.ansoft.com/workshops/aeroee/nasa_tim_regan.pdf Thanks Jerry! That kept me busy this evening. I learned more about free piston SE a...

Greetings all! I checked my tracking and the status has changed to: Item sent to destination country Getting closer (4-6 more weeks!)… Interestingly, the moderator for the Hyporex forum has decided to delete my posts due to criticism. Read the re-posing below and let me know if I was too critical… :...

Ordered mine September 13. Got a shipping notice the other day that it is in Pakistan customs...

I am SO EXCITED!!!! I have so many tests to conduct and will share the results here...

Hi Vamoose! If you have any questions, PLEASE ASK! I entered this forum largely due to this/your post. Yes I have interest in this topic and will now continue to experiment with the concepts discussed so far and show a working model of the “Vamoose MPPT”. As I have mentioned before, I am an EE and n...

Hi Again Vamoose! First off, I apologize for taking over your posting here with my babble. Feel free to tell me to stop… I decided that tonight (my time) I would write about the signal processing needed to generate an error signal that would be used to drive the PWM stage duty cycle percentage to op...

Welcome Seeker and good luck at your university, I’m not a ME (and also new like you), but I believe your teacher is asking you how the rotary inertia of the flywheel helps overcome the fact that a typical Stirling engine is only a single cylinder. And depending upon the type of Stirling, will only ...

Holly smokes Vamoose, I feel more like I am way out of my league here. With that solar setup you got, you are serious enough, and also well written/spoken. You truly hit the nail on the issue of using a solar MPPT with a Stirling; it can’t/won’t optimize the RPM & Torque. Solar is basically a co...

Hi qwerty! I'm new and still reading posts. One of my applications for these motors is similar to your application; functional art! So how much power are you looking for? Take a look at my Big Stirling Engine post and a company I found to see if this might be something of interest for your pizza ove...

One of our older machinists said it is a specialty measuring tool; height(s) and angle gage. He had seen them before in his past but never found a good use for them and thus never got one…

Dumb question, how does this puppy start? Does it use internal air flow from the motorized fans to start the Stirling Cooler?
