  1. I will respond in the order you listed. You typed: "Your idea has a couple flaws – the first is that there isn't any fall over between the power inputs on the Nova – they will just draw from whatever battery has the highest voltage. So your "backup pack" will add to the battery life of your system but not work the way you want it to." Me: In my testing the Nova power system, with the 2 Hirose inputs is not wired in a true parallel. My reference to the amount of time the "backup" battery would last was if the main battery were to fail. The time I listed for the backup to power the Nova was listed lower than the actual capability of the battery. You typed: "A 3S lithium battery has a nominal voltage of 10.8v and a range of 12.6v to 7.2v (with a safe cutoff of 9v)" Me: That is actually a good idea, that would convert the 2nd battery into an absolute take over battery after the main pack had been exhausted. The problem I have with that, I have never powered a mixer with 12 volts, I am not a fan of lower voltage/higher amperage. So, I don't think I could talk myself into a 3 cell pack. But it is a good idea. I had a conversation with Glenn about this a while back. I might make a board that would "switch on" the second battery at a select voltage in order to turn on that pack after the primary pack drops to a select voltage. In doing this, I could have the 2nd pack turn on while the primary pack has 20 percent left in that pack. That would then turn on the 2nd pack and in effect, turn the primary now to backup duty, so should the 2nd battery fail, the primary pack would then have 20 percent power left to power the unit. That circuit would probably utilize a zener diode to do the switching, because I am a zener fan. And it has a really cool symbol. Can someone draw superhero Zenerman? You typed: "The second flaw in your proposed batteries is a battery management system (board) as raw cells can be easily destroyed if you draw them down too low, which the Nova would happily do as it's cut off voltage is lower than the battery's discharge limits. Additionally "raw" cells aren't supposed to be used out of battery packs, they are, but it is risky." Me: I took a picture of just the cells. There are many parts missing, nickle strips, BMS board, balancing connectors, wire, cell holders, heat shrink, power connector, etc. I will take another picture of all the parts that it takes to make a battery pack. You referenced "out of a pack". It's not in a pack until I build it. I have been using my own packs for years, as well as my own battery distribution system. I have never used a distribution system or battery pack manufactured by anyone other than me. I have been using lithium batteries for 21 years with no problems so far. My post was just showing the smaller cells I am switching to because Nova/MRX uses so much less wattage than my previous Nomad/QRX setup. Nova with 8 receivers going and Zaxnet transmitting uses about 15.5 watts. That is still amazing to me. You typed: "but the other option, and probably more reasonably, is to just use that second shoe and just add a fresh battery when the first one gets low (as the new battery will take the load, as it is fresh off the charger, and the voltage is higher)" Me: The problem that I have with that is there is then no protection for a Hirose female connector failure, a Hirose male connection failure, or a battery pack failure. In my Nomad setup, I ran 2 packs in Parallel, so if a pack component failed, Nomad would continue to run. I would only know if there was a failure later, when the charging showed a disparity in the 2 packs. My charger would also indicate if there was an individual cell starting to degrade. I have never had a pack failure, they have just simply aged and been removed from service. Thank you again for your input, Martin
  2. Pete, Thank you. I just wasn't clear what you were meaning there. I will go back and address your first reply. Thank you, Martin
  3. Shastapete, Thank you for the response, I can address most of it. The only statement I'm not clear about was "Additionally "raw" cells aren't supposed to be used out of battery packs". What is meant by that? Thank you, Martin
  4. Hello gang, These are the batteries I will be using to power the Zaxcom Nova with MRX414 receivers. The tall purplish one will be the "main' battery, and is rated at 5000mah and thanks to the extreme efficiency of the Nova and the MRX414 receivers, 4 of these will power the Nova and all 8 receivers and Zaxnet for a minimum of 3 hours 45 minutes. That pack will weigh about 12 oz. (340 grams). The AA energizer is there for size reference. The small battery will be my "backup" battery that will be plugged into the other Hirose 4 pin port on Nova. They are rated @ 1100mah. 4 of those batteries will run Nova with 8 receivers and Zaxnet for a minimum of 35 minutes and weigh about 6 oz. (170 grams). That is really an impressive number to me. Did I leave anything out? I usually do. Martin
  5. Run, I was going to be able to let you know how long it lasted, I'm still scheduled for my antibody test next month, but since I get my Delta variant booster in the morning, I'm sure antibody data will get modified. I hope, I guess. Thanks, Martin
  6. D., Your welcome, I'm gonna be by myself, again, for this shot, tempting to sleep in my vehicle in the hospital parking lot, so when I get up I'm already there. Thanks, Martin Philip, That is a great question. If I can remember to ask, I will. But if we were betting, I'm gonna guess Pfizer only. I don't know how long from the time they shoot me up until the time it is available in regular vaccine places. Again, guessing, I would say 4 or 5 months from now. Unless it kills a bunch of us testers, and they have to start over designing it. Thank you, Martin
  7. Rich, I see where your thinking there. Well, your not wrong, but I think these are not very standard times. I get my booster in 48 hours. I will update as soon as I know what happens or doesn't happen, but they have to try something, and it takes so long to go from Guinea pigs like me, to all of the rest of you. So, my thinking, they have to start testing that booster now, can't wait. I will know more in 2 days and then I can update. I have to sign about 30 pages of lawyer talk beforehand. It won't be boring, so there is that. Thanks for your input, Martin
  8. Rich, Thanks for that. Unfortunately, since I'm testing the Delta booster, if me and a few select other guinea pigs don't try it, there won't be anything to VAERS. I'm now about 10 1/2 months past my first shot, so I'm guessing when I go in this week, they will antibody test me and then shoot me up. Will be interesting. Thank you, Martin
  9. Well, I'm guessing I was the first mixer on the planet to be Coronavirus vaccinated , and subsequently, I will probably be the first mixer on the planet to get their Pfizer Delta Variant booster shot. Who among you that was vaccinated would look to eventually get the Delta Variant booster shot? Why or why not? Thank you, Martin
  10. For tomorrow, in Atlanta, need to know Zaxcom.
  11. May 24th, Monday $800. for the day, scripted, call time 6pm. Please message me. Rocky Mount NC.
  12. JWill, Yes, I was a tester of the Pfizer/Bioentec Coronavirus vaccine. Are you saying that you have friends, one was vaccinated and the other not vaccinated, and they both were infected with Coronavirus? Thank you, Martin
  13. TV, You are correct sir. I had to get "creative" with why I would be eligible for the shot, in order for them to provide me paperwork that I had been vaccinated. I started this post as soon as I had it verified. I was probably the first sound mixer on the planet to be vaccinated, I would imagine. And although they make you sign about 40 pages of of "death may occur,....", your head may fall off, etc., they get really testy if you refer to yourself as a Guinea Pig, while in the study facilty. Thank you, Martin
  14. Ah, yes, maybe that was not clear, sorry. I am 5 months after having received my 2nd Pfizer vaccination shot. Sincerely, Martin
  15. codyman, can she get an antibody test, if its good to go, then, when she comes home, assuming a house, not an apartment, put all her clothes in a box, sterilize the box, scrub up, mask on, straight to the long hot steamy shower, clean your mouth, eyes, ears, nose really well, then all good to go? What's wrong with my theory? Oh, and the box of clothes go straight into the wash. Thank you, Martin
  16. Cody, Glad shes doing great. Yes, wacky fits for a description, the vaccine is the same, most people, it's a minor annoyance, then, bam, the next guy it's tough and you are really sick. But I still would get vaccinated if I had to do it over again. Thank you, Martin
  17. I am not in California or Nevada, so I can't help there. As far as failing kidneys, if I had a mother in law with failing kidneys, I don't think I would be getting her vaccinated. I can't imagine going thru the chills, etc., with failing kidneys on top of it. Everyone has to make there own decisions on this, but I would live in a cave as opposed to getting vaccinated with internal organs failing. Tough choices.
  18. You can google the lists to see all the people who have been "qualified".
  19. tourtelot, I would recommend you have blankets and sweaters on standby for when you wake up after the 2nd shot. The first shot was great, I slept like a baby for a few days after that one. No memorable anything from that one, but on the second one, since it was summer, who has a sweater nearby or heated blankets in the summer? The chills were aweful. I worried about chipping a tooth. Apparently, one of the other recipients did chip a tooth from the chills. I think I would say that if you are, say a couple, I wouldn't both get the 2nd shot within about 3 days of each other, one of you has to be well. I think the odds are against both of you getting really sick from getting the 2nd shot, but the odds of me getting into a crash today are very low, but I will still wear a seatbelt. Thank you, Martin Rich, I don't think I understand the question. Can you clarify that question? Thank you, Martin newzhack, Those were your symptoms after the first shot? Thank you, Martin
  20. Philip, All good questions. In order that you asked. I received the Pfizer version of the vaccine. Before I start answering the next question you asked, I want to say that not everyone is going to get as sick as I did from the vaccine. Don't fail to get the vaccine based on what I'm about to say. Yes, I got very sick from the vaccine. But I still think the vaccine is better than what could happen to you from Corona virus. I had heart pain, I had lung pain and problems, I had terrible coughing, I can expand on that if anybody wants me to, my fever was a few degrees high over normal, then it went back to normal, then it started plunging down into the hyperthermia range. The low temp was really concerning. The arm pain was probably not much less than had I been shot in the arm with a gun. That lasted for weeks. My arm began to atrophy. The good news on that, from not booming for so long, that little pinch feeling that I had, for years during booming, is gone. There were other problems, symptoms too, just look at the side effects from Coronavirus. As far as booming during that time, to give you an understanding of how much pain and inability, I could not have held up a lav mic, much less a boom. Now, from overworking my left arm (the vaccine arm), that arm is stronger than it's ever been relative to the right, or dominant arm. I can now boom at least as well as I could before the shot, I have practiced a lot. Your question about contact with others with or without the vaccine. The amount of people I am in contact with the vaccine is probably very close to zero. I can safely say that because of the amount of people that I am in contact with is very close to zero. As to your age question, I am not near 65 years old. As to your question about where I was vaccinated it was a private site. My 2nd shot, or booster, was in early September. That is the shot that can make you miserable. I am skipping the cost question as it does not apply to my shot, so I have no knowledge about that. The appointment questions also do not apply to my situation. Feel free to ask any questions, Thank you, Martin
  21. Hey sorry guys, I didn't get notification that I had responses to my post. No extra vaccine, but I'm super full of antibodies, drain off a pint of your blood and I'll give some. You know, like when you put too much oil in the lawnmower. Thanks, Martin
  22. Hello all, I am well past my 2nd vaccine shot, does anyone have any questions? If you feel I didn't post this in the right section, let me know. Maybe the equipment section, ha. Thanks, Martin
  23. Iron, You made me smile, if only it was that easy. Sincerely, Martin
