  • Christmas Cookies: Mystery Date Code

    Christmas Cookies: Mystery Date Code

    Spotted during a grocery trip:

    Christmas Cookies - date code
    Christmas Cookies – date code

    I’m sure they have a good reason for whatever date code format they chose, but 2012272 seems open to misinterpretation in the runup to Christmas 2022.

  • Encounter With A Cash-for-House Scammer

    Encounter With A Cash-for-House Scammer

    This conversation started during the few hours when I had to turn off my phone’s incoming-call whitelist filter:

    Cash Home Sale SMS
    Cash Home Sale SMS

    Seems to me a cash-for-house buyer who believes anything the seller says about the property is both new to the “real estate” biz and not destined for a long career. Obviously, the whole exchange attempts to increase my engagement and make me agree with everything going on.

    Now, should you happen to be moving to the Mid-Hudson Valley and need a really nice shop with an attached house, let me know: we can work out a better deal.

    Protip: if you’re in a position to stack seven thousand Benjamins on our kitchen table, don’t get between us and and the horizon.

    There is a reason all my calls and texts go through a whitelist filter.

  • Drug Fact Sheet: Overdose

    Drug Fact Sheet: Overdose

    For reasons not relevant here, a new medication has entered the house, accompanied by its Drug Fact Sheet (blurred because you do not have a Need To Know):

    Drug Fact Sheet
    Drug Fact Sheet

    The background squares are a scant one foot across.

    The other side of the sheet is equally dense.

    One should review this with each refill to check for new or changed information. Of course, there are no change bars or similar hints.

    It might kill ya or cure ya, but you’ll never figure it out from that torrent of verbiage: just like software EULAs, nobody can possibly read and comprehend that stuff.

  • Leaf Bag Flagwashing

    Leaf Bag Flagwashing

    The data plate at the bottom of the the leaf bags we get from the town seems intended to set expectations at a certain level:

    Dano Leaf Bag - data plate
    Dano Leaf Bag – data plate

    Which is immediately belied by the situation at the other end of the bag:

    Dano Leaf Bag - crimp line typo
    Dano Leaf Bag – crimp line typo

    OK, it’s just a typo that could happen to anyone, but it first appeared last year and seems to be continuing. Possibly the Town of Poughkeepsie bought a lot of bags and we’re working through the stack.

    However, the built-in gashes along the sides of some bags were a new feature this year:

    Dano Leaf Bag - side gashes
    Dano Leaf Bag – side gashes

    Perhaps a misalignment in the folder or stacker:

    Dano Leaf Bag - side gash detail
    Dano Leaf Bag – side gash detail

    Enough bags had slices, perhaps four in some ten-packs, to justify keeping the packing tape dispenser at hand while we were shredding up a storm:

    Dano Leaf Bag - side gash detail
    Dano Leaf Bag – side gash detail

    Which frosted Mary pretty severely, as she recycles the used bags as garden path pavers after distributing their contents as mulch, so she’ll be stripping plenty of tape next year.

    Although I’m not privy to the Town’s dealings, Dano’s chart suggests the bags cost about 40¢ in truckload lots, about as much as Lowe’s charges for similar bags in retail five-packs. Surprisingly, you can also buy the same Lowe’s bags from Amazon for a lot more, suggesting some folks live much further from a Lowe’s than we do.

  • Humana Email Unsubscribe FAIL: Redux

    Around this time last year, Humana was spamming me with emails sporting a misconfigured unsubscribe link, so that I could not get myself off their mailing list.

    This year, they have the unsubscribe link set up properly, except …

    Humana email unsubscribe rejection
    Humana email unsubscribe rejection

    Apparently my email address was good enough to get their junk email to me, but it’s not good enough for them to stop sending junk.

    I was pretty sure this was deliberate last year. Now, I’m certain.

    And they want me to trust them?

    You can’t make this stuff up.

  • Outdoor Sign Wiring

    Outdoor Sign Wiring

    A dentist’s office has been a-building for what seems entirely too long, but the outdoor sign finally went up. Being that type of guy, I had to take a closer look at how they wired up the LEDs:

    Outdoor sign LED wiring
    Outdoor sign LED wiring

    That’s exactly as half-assed as it looks: unprotected PVC wires emerging from raw holes drilled into the backplate and burrowing into unsealed laser-cut acrylic loosely seated behind the white character boxes.

    Everything you see is gonna be full of bugs in no time!

    I’ve done similar botch jobs, but generally for my own use …

  • Hyde Edge Recharge Vape Pen Teardown

    Hyde Edge Recharge Vape Pen Teardown

    Now that vape “pen” refill cartridges are (mostly) dead, roadside debris has gotten chunkier:

    Hyde Charge Vape Pen - as found
    Hyde Charge Vape Pen – as found

    It’s a Hyde Edge Recharge vape pen or it could be a counterfeit. You (definitely not me) get “up to” 3300 puffs from the 10 ml container, with 50 mg of nicotine ensuring you can’t get enough and will come back for more. Although I don’t follow the market, “disposable” vape pens can still contain the fruity flavors prohibited in refillable pens, with the added decadence of throwing the whole thing away when the tank runs dry:

    Hyde Charge Vape Pen - components
    Hyde Charge Vape Pen – components

    My admittedly inexperienced eye says the “tank”, which is really just a fiber cylinder soaked in fruity juice + nicotine, still has plenty of hits remaining.

    The Basement Shop may never smell the same again.

    Of more interest, the silvery lump wrapped in a white felt strip is a 600 mA·hr lithium cell that slurped 406 mA·hr through its USB Micro-B jack when I recharged it. Perhaps the user victim sucker tossed it when the battery “died”, being unable / unwilling / ignorant-of-how to recharge it? The yellow aluminum case seems faded on the mouthpiece end, but that might be a stylin’ thing.

    A closer look at the electronics payload:

    Hyde Charge Vape Pen - electronics
    Hyde Charge Vape Pen – electronics

    The two red wires over on the right went to the coil in the draw tube to the right of the “tank”. Not being interested enough to care, I wrecked the coil while extracting the rest of the contents. Comfortingly, the red and black wires from the PCB go to the positive and negative battery tabs.

    A closer look at both sides of the PCB:

    Hyde Charge Vape Pen - PCB detail
    Hyde Charge Vape Pen – PCB detail

    The SOT23 IC sports an LTH7 topmark corresponding to an LTC4054-4.2 Standalone Charge Controller (Analog Devices absorbed Linear in 2017). The two LEDs to its right glow red during charge and white during each puff.

    The black felt disk covers an anonymous pressure sensor activating the coil during each puff. With four pins, the sensor must be far more complex than just a switch, but nowadays puff sensing could require an entire ARM microcontroller.

    Speaking of microcontrollers, there’s always this fate:

    I fought down an almost uncontrollable urge to amputate my arms at the elbows and cauterize the stumps …
