I did an electroporator design up to the testing stage with funding from 6 kickstarter backers and $2k from Bryan Bishop. It's open hardware published on github at https://github.com/kanzure/culture_shock. It is physically in only two prototypes, I have one and Nathan McCorkle has one. The six kickstarter backers would not contribute any time testing and it stalled out for lack of a complete enclosure -- it needed a laptop just to turn on -- no buttons for setup and fire... So, I worked for 6 months for $3k and didn't get to a viable product. Case study complete. Now aiming at RV solar PV battery appliance designs like: on demand teapot, DC microwave oven, DC refrigerators, etc where the wiring between solar PV panel and battery bank is small gauge, easy to wire into a house, easy to repair, and the controller manages batteries of most any kind individually so the user can change them out by messages like "replace cell D8", "cell B3 now has 2 Ampere hours, half its original capacity". Now I'm not planning to release any of those until having a good way to make plastic moldings in 100's. So I'm designing molding equipment also. The 3DP machines have matured and many are available for cheap, so maybe I'll use some of that for enclosure production, but still thinking it will be by 3D printed MOLDS filled by low pressure injection of thermoplastic and with fairly visible mold parting lines done slowly, automated, so the temperatures of the mold go up and down for molding and release. It needs a cheap automated part eject/remove/stack robot also. Anyone heard of progress along those lines so I could buy small plastic moldings in the 100's for about a dollar a piece, instead of make? -- John Griessen Albuquerque NM -- -- You received this message because you are subscribed to the Google Groups DIYbio group.

Just seeing this after moving my workshop to storage after losing a tenancy... Funny how Bryan was introducing me to some of his business friends around the same time because my electronics design rates were "reasonable" on the culture shock electroporator project partly funded by Bryan. I heard what kind of apartment aggregating internet nodes with radios, (like the Helium network), they wanted, gave them a quote, never heard back... The business friends were way too cheap to pay my easy rates... I've met in person with Bryan 5 times maybe, and he's talked about having cheap lab work done in Ukraine, (before the war), his designer babies effort/plan as something to do on islands or in regions with different than USA laws...which is where I lost interest. -- John Griessen Albuquerque NM off-grid and RV DC power appliances, and maybe electroporators again some day (with necessary custom plastic enclosures) -- -- You received this message because you are subscribed to the Google Groups DIYbio group.
