because I think you are a guy that likes to solve problems. I could be wrong but that is not how I take your posts. If this project does not pan out, it would not be the first time I have bet and lost.
Now, WoodPelletSmoker get back to the test bench and solve this problem and I will give you my $$. :idea:
I discussed with many China engineers, all we conclude
#1. not any electronics can withstand 275 C ( MEATER claims so). Nothing to say its video implies hundreds of C degree ( facing flare directly)
#2. none commercial battery can be placed inside a grill whatever measure it takes. explode risk is too big. We do not want you to be killed in your kitchen even though the possibility is 1 out of 100, or 1000, or 10000, or a million.
#3. We do not believe that it has any breakthough on battery. If yes, there are many more areas need the "SUPER" battery than kitchen.
We are thinking capacitor battery, it can be charged very faster, but size is too big, much bigger than Li-Ion battery.
We are thinking wireless recharger, again size is too big and speed is too slow.
We are thinking to add a water jacket around the electronics section, again too big, and battery still has risk to explode.
All in all we think MEATER is a super magic and it will never come to ture.
But we learn something from meater.
We can make a thermometer with electronics left outside the grill. The temp. sensore is inserted into a stainless steel needle. You need to drill a hole on your grill for the needle going through.
We can make a big base set. You can hang the base set anywhere at your kitchen,. with BIG LETTERs of LED for the elder.
