  If this isn't in a SonicScrewdriver by Christmas, then we have failed as a community.

  Security in these: It is just adequate for the purpose. All who are engaged in those petty crimes, why these smart wheels were introduced in the first place, aren&apos;t the ones capable to go through even such simple system. Someone capable to hack through it, those do not get involved in those shoplifting activities in the first place.<br>Having everything super secured disregarding the purpose is just plain stupid. It ends up into system where the &quot;security&quot; features and their consequences cause way more expenses in normal business disruptions than the damage it is supposed to prevent. Don&apos;t forget you can just hold the cart corner off ground a bit and there is nothing the wheel locking can do about it.

  The unpopulated footprint (labeled &quot;N100A&quot;) is likely for a different package version of the populated part labeled &quot;N100B&quot;

  Ahhh something for the purists. This was a great example of reversing from scratch. Nice work

  What really surprises me is they don&apos;t have a tiny generator on the wheel providing power.<br><br>Great talk. Would listen for another 38 mins to you talking excitedly about shopping carts.

  I wonder if you could create an EM pulse or tone strong enough to trigger all of the shopping carts in the store to lock up. &nbsp;The 8KHz would probably need to be a harmonic of a higher frequency carrier in order to transmit far enough. &nbsp;The technical challenge would be interesting, although actually using it would be a dick move.

  How to turn a simple search and record task into a super long presentation saying everything but the pertinent information. <br><br>Found signals within 2 or 3 minutes,recorded it to my phone and field tested it at local tesco with great success! played back next to the wheel within 30 cms.

  It&apos;s really great to see the amish embracing technology

  That unpopulated chip is probably just the pinout for an alternative wake-up chip since the signals are routed to both footprints.<br>They will just use whatever was cheapest at the market that night

  This is the kinda fundamental research into esoteric things that makes hacking fun.

  This reminds me of my dad if he was born in these days<br><br>10 years ago he brings home one of those shopping cart token securing mechanisms; he wanted to know how it works and in his words “a tamper-proof screws can’t stop you if you have a tamper-proof screwdriver”<br><br><br>Re: Not asking where he gets things, I&apos;m the same with my dad<br>He has a system called a DTL - Don&apos;t tell lyn (i.e. my mum)
