I wish I had seen this earlier. I have spent the last year modifying the propellor beanie to a tinfoil propellor beanie which is rated up to 60GHz and will screen out all alien wifi signals and is IEEE 802.11a51 (Area 51) certified as well. I could have had this project finished months ago and been selling them already.
FAST UPDATE: I have a new aluminum foil pack in stock... and the case extremes have not got any push-in tab!!! The strange thing is that there is a "complex tab mechanism" in one of the four long sides of the case and I cannot figure how it works -- this a difficult puzzle for bed-time, I'll give it a try tomorrow morning ;-)
Max: "Seriously -- did you already know this -- am I the only person on the planet who didn't have a clue?"
Arrgghhhh..... I had no idea!!! I fact, I always throw the carton case to the trash bin as I thought it was useless -- I even wonder why the case had a razor/saw in one side if it could not be used in a clean way!!!
By the way... do you expected something spectacular/shiny when the Crazy Russian wore his sunglasses? Or maybe am I too biased by youtube amateur scientist videos? ;-)
@antedeluvian - I was going to say that even our cheap-n-nasty Australian home brand ones have this feature, but yours must be even cheaper and nastier. AND ours have metal cutters!
I did notice on ours that NOWHERE on the box does it tell you to push the tabs in to hold the roll. You'd think they would put this in large letters on the box. Better still, get the packing machine to push the tabs in for you - why would you not use them?
I have not had time to watch any of Russian Hacker's other videos but clearly I need to do so. Sigh - there's so much to learn......
As an aside, once when we moved I bought a 3 Km roll of cling wrap (household rolls are around 60 m) and we wrapped all our furniture in it before moving it, Works a treat - no scuffs or dirt marks.
The glue on the box almost always gives up the ghost and you are left with this flimsy flap of cardboard.
I find the reverse is true on cereal boxes. Cereal box tops have these fancy cut outs to allowq you to close the box up once you have taken a serving. I find that they use such strong glue that you rip the flaps the first time you open the box, destroying the cutouts and tabs so carefully added to the box design.
Aside from the fact that neither the no-name cling wrap and Alcan foil that we have in our house have no fold in tabs at all- there are even greater problems that need addressing.
1. The glue on the box almost always gives up the ghost and you are left with this flimsy flap of cardboard.
2. The cardboard saw tooth perforator goes blunt after 10 cuts or so and trying to separate a length of cling wrap becomes rather irritating.
3. Why Oh why will cliong wrap never work the way it is supposed to. It will cling to itself when you don't want it to but when you wrap it around your sandwiches there is no adhesion. Try and get it to stick to a container when you want it to- there must be a secret or all these products are persecuting me- anti-antedeluvian as it were!
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
