Power consumption involved with driving the refrigerator has been improved by a massive 40x. This is due to data collected from the test setup driving the selection of new electrical components. With additional testing this c…
Read article ↗Tests are underway. New information is being discovered which will lead to refinement in technique. Outcomes will be listed in a later post. A number or secondary products have been added to the products page. These were gene…
Read article ↗An important test is about to be run that will decided how the next stage of the spot cooler will proceed. Custom sensors made for this specific test and have been calibrated. A micro controller with GUI output was also made.…
Read article ↗Reworked theory of spot cooler. Designing electronics needed to power spot cooler. Calibrating measurement devices.
Read article ↗For the past two months I have been experimenting with methods of generating/controlling pneumatic pressure that can be turned ON and OFF with electronics. An example of a pneumatic device controlled by electricity would be h…
Read article ↗Have been improving on how liquid moves through pipes and have succeeded in making pneumatically driven switches from stock material. The reason effort is being put into making these switches is cost, customization, and footp…
Read article ↗Fluid drivers were blind to the movement of fluid that they were driving. It was clear from early tests with the fluid driver that some sort of sensor feedback was needed. A circuit was made to sense the fluid, and feed data…
Read article ↗Fluid driver has been completed. It allows allows for the control of liquid as its pushed/pulled through pipes. I plan to make a couple more of these and connect them together via micro controller to create more advanced liqu…
Read article ↗Currently making fluid driver (electrically driven) for the cooler.
Read article ↗Measuring the intensity of changing magnetic field is difficult to do. The changing characteristic adds noise to any metallic sensor that you place in the field (see last post on metallic temperature sensors). To circumvent t…
Read article ↗Thermocouples and other metallic sensors will pick up EMI from changing magnetic fields. This adds noise to my data. Placing thermocouple length in SS braid does not prevent EMI for the fields it is exposed to, I think the fr…
Read article ↗-Trouble shooting with the FEA revealed a long standing problem I had been having. The photo sensor output kept climbing even though it appeared to have a constant laser light source. Replacing the laser with a LED confirmed…
Read article ↗-Experimented with making custom heat pipes out of soft copper tube and later borosilicate tube. Results inconclusive. -Attempted to flatten MC metal with hammer, anvil and propane torch. Rusted due to heat. -Made nichrome wi…
Read article ↗-Moved to new location in Houston TX. -Developed step diagram of how cooler will function. Simulated operation in excel to 500 steps -Experimented with non contact IR thermometers to measure cooler temperature. This was to pr…
Read article ↗-Made one-way valve and ON/OFF valve for fluid system. This allows for the one directional flow of liquid and the ON/OFF flow of liquid. Also made one-way pressure driven pump to move liquid. -Made numerous magnetically drive…
Read article ↗-First tested Faraday Effect Apparatus (FEA) on light table to measure strength of magnetic fields. This was done as a safegaurd to prevent EMI from creating errant data points on my datalogger. Something that might have happ…
Read article ↗-Fernbrake LLC created -Developed method of making fluid pipes -Made 'push-pull' driver (mechanically driven) to force liquid through fluid pipes.
