STATUS: The emission free Revolution Energy Converter LAB-Model Ver.2

15/2 2020 Adjusting the distance between the middle fins and the Revolving Shutter. Quite a lot of friction as indicated by the sketch and the photos.

Putting it all together, next steps will include:
1 - Mounting the Sensors in the mid-layer fins. (Glue and solder)
2 - Trimming and testing of the Revolving Shutters with all layers assembled.
3 - Test running with logging for analyse

There are still issues to deal with, but they are not considered as show stoppers:

The DynamicLink software is still in development:
A - The stepper motor driver to control the revolving shutter motion is rudimentary and needs a "ramp up" function but it works
B - The program "thermist_Pt500" is now 10 thermistors but not tested.
C - Needed a function to measure pressure (we have pressure sensors)
D - Have found 4 pcs "Hall" sensors for rotor position. The old mechanical sensors was not fast enough

5/2 2020 Adjusting the distance between the upper endplate and the Revolving Shutter. Revolving Shutter distance is quite OK to the upper end plate side. Minor adjustments are needed

1/2 2020 Adjusting the distance between the lower end-plate and the Revolving Shutter. Revolving Shutter is in friction with the conducting fins of the lower end plate at their periferal surfaces

16/11 2019 High precision glueing of the shell layers on to the end plates to prevent gas leakage. This was not easy. We had to try several times with soft silicon for the nil-parts and a home made thermal paste with graphite for the conducting alu parts

28/10 2019 Glueing of the second Revolving Shutter disk. The REC end plate on the granite table garanties higher precision.

19/10 2019 Pairing of the mid layer fins that will hold the electronic sensors . Each of the two separate pairs consists of one conducting and one insulating nil fin bridged together with glue.

9/10 2019 "BriefcaseSetup15" containing the complete DynamicLink HardWare and SoftWare is updated. As the name indicates, it's all contained in a briefcase

26/9 2019 Badly glued parts successfully separated including guiding pins

29/8 2019 A precision totally flat polished granite plates"glue-table" is ready
First 2 attempts were failures due to wrong choice of glue and bad distance. Learning experience. But the two plate high precision glue table is a hit!

3/8 2019 First Revolving Shutter is glued. The balsa "Revolving Shutter" mid layer was sanded down to 1,7mm thickness .
Maybe we will need to add thickness when gluing the boundary shells to allow for a frictionless Revolving Shutter spin while turning its "Work Generating Volume".
No balancing of the Revolving Shutter was done. We were not able to slim down the counter weights in Motala. By that we are, unfortunately, limited to do low temperature slow speed testing with these type of Revolving Shutters.
The glueing seem successful, but the screw-tightening of the "sandwich" Revolving Shutter has to be done later hoping that the assembled layers Alu-Balsa-Alu will form a Revolving Shutter less than 6mm thick.

27/7 2019 Second integrated endplate is successfully glued. Started to grind the Revolving Shutter mid layer.

3/7 2019 First integrated endplate is successfully glued. The program "thermist_Pt500" is updated to v.15 with higher accuracy and double MCP3208 A/D over SPI that will report 10 planned thermistors.

21/6 2019 All mechanical parts are built (31/5 2019) and transported to Motala together with the DynamicLink electronics in its briefcase.
