    this was a thing 20+ years ago and shockingly people realized you don't get a lot of sunlight in your cubical.

      I had one of these in my sub-basement recording studio for ..10 years? It worked flawlessly the whole time on the few dim incandescent bulbs, satanic candles, etc
      It's still used as the remote keyboard when tracking drums from the other side of the room.
      I tried to find another one for my second studio tracking station but they stopped making them. UNTIL NOW
      Actually if the battery lasts around 10 years, that's about how long the one downstairs has been working flawlessly without ever needing charging.

        Yeah some low power stuff does work better than you'd think, I have a TV remote with a solar cell and thought "oh well, this is for the basement, good thing it can be charged with a cable, too" but the damn thing is somehow going after 5 years in a windowless room in the basement with LED lights when it is being used and dark otherwise.

        Satanic candles are unusually efficient light sources for solar panels, not everyone is burning those; check your privilege

        • Indeed I only use LED candles for my satanic rituals. Unfortunately the only spirit I've been able to summon is a coal roller who keeps ranting about his neighbour buying a Prius.

    • It is challenging with florescent, nearly impossible with led. I'm guessing a primary cell of extremely low self discharge rate and the solar to supplement it. And a shorter than 10 year warranty
    • I had this solar logitech slim 12 years ago. It kept itself charged off the ambient light from an overhead 60w bulb and my monitor's light output. Never had a power problem with it over many years.

      I have a very old Logitech "Solar" keyboard that has worked flawlessly for at least a decade or two on my desk with no direct sun.
      I think the PV panels are of a different type optimized for low light since I've never run out of charge.

  • ...doesn't exist.

  • The Logitech K750 is already solar and wireless and I've been using them for nearly a decade.

      if they discontinue the product and then bring it back when the news cycle has sufficiently buried it, then they can claim it's a new product and their shareholders will see how innovative they are.

      I hope this means they will "reinvent" the K740 since I can't find anyone else making a backlit scissor-mechanism low profile keyboards. The Cherry Stream would be my most likely replacement if it had backlighting.

  • I can't get my solar powered calculator to work with LED lighting, I doubt a keyboard will charge much.
    • Solar cells can be made to be sensitive to different wavelengths of light.

      Crystalline silicon panels are better for sunlight, while other semiconductors and amorphous silicon are better for broad spectrum and higher wavelengths, although overall are less efficient.

  • Hope it has a charging socket too. I think people don't realize that pulse-width modulated LED lights don't really provide enough useful light to charge anything, but maybe this is for road warriors who want to show off their Logi gear on the beach.

      Must be those fancy dimmable lights, because plain old regular LED bulbs don't use PWM - they are using a linear regulator that just controls the current through the bulb. This compensates for varying line voltages (so they don't dim when you turn something big o

    I've had this one for EVER and it's still working perfectly. I don't think they make em anymore or I'd have 2.

    I find it amusing when "solar powered X" can still make news headlines, when we've had things like solar powered calculators for 45 years now [vintagecalculators.com]

    Means no.

  • Some classic equipment was way ahead of its time.

  • My old Microsoft Natural ergo keyboard has worked fine since 1999. Not everything needs batteries (or proprietary Logitech receivers...).

  • Arrghh, it's the "num pad on the wrong side" design with laptop keys. I would pay hundreds of dollars for a tenkeyless mechanical BLE keyboard that never needs a wire. Ya know, "actually wireless" not "sometimes wireless except when you need the wire to charge". I'm fine with no caps lock LED since that's my ctrl key - or it could be eink. I'd also be fine with AA cells instead of solar cells since the lithium variety can last years.

    But no, these fuckers glue lipos into everything so you need to buy two $10

What good is a ticket to the good life, if you can't find the entrance?

Working...
