  1. Trump to recognise Jerusalem as Israel's capital.

    Trump should not get involved with the Jerusalem tribes. Defining their capital is their business and nobody else. Moving the embassy to Jerusalem should be requested by such tribes; and the embassy should be for all the tribes/countries claiming Jerusalem as their capital, not only Israel. If the embassy is only for serving Israel, leave it where it is.
  2. Flashlight battery polarity (mixed) ?

    It is different to say 'the flashlight does not turn on' and 'the voltage is zero' A LED will not turn on with only 1.5V. Needs to be supplied with more than its Vf.
  3. Copy and paste...

    ¿? Did not have a clue there was a related movie. Just believe it is way too sad that all the knowledge accumulated has to end wasted in a graveyard with no 'recycling' use.
  4. Copy and paste...

    Has any research been done, experiment or attempts of any sort to transfer the knowledge and experiences from the brain of a sixties lucid person to a twentiesh year old ? It is usually called teaching, but in a more technological and quick way. Short of implanting a USB socket under the hair... Would such be happening in 100 years from now ? Implications would certainly be impacting.
  5. To install a wireless printer to Windows 10 ?

    Thanks to all of you, guys. The PC is a modern one with built-in WiFi and enabled, and tested working fine.. The printer is old without WiFi capability from factory. An USB-to-WiFi adapter is much newer than when the printer was designed, has been added/plugged to it. The adapter supplies its own 5V for operation and for 'plugged-in' detection at the printer receptacle That USB-to-WiFi adapter is proven working, allowed WiFi internet to a laptop in another scenario, with zero setups, drivers or anything. Plugged in and performed. It works like a 'bridge'. Transceives USB 'language ' over WiFi signal. Will explore the ad-hoc setting.
  6. Hi. A printer that works fine wired trough USB has been added a generic adapter at its USB jack that allows Wireless. How to tell Windows 10 to recognize the printer is now in wireless mode ? There is no WiFi routers nor other wireless networks related in the premises. A PC and a now wireless printer. [ PC<------>printer ] For a 'normal' wireless printer to work with only one single PC; is a wireless router needed ?
  7. What is the difference between (same wavelenght) LED light and a laser light exiting a diverging lens ?
  8. Educational toy/gadget I cannot find...

    Yesssss ! Thank you +1
  9. Cannot find even a picture of it. It is a fountain enclosed inside a clear plastic cylinder, about 10cm diam x 20 cm high, with a blue dyed fluid in it. After 'charging it' upside-down, when placed upright, a centered nozzle squirted upright, a stream as a fountain, with a duration of a few minutes. I think I bought it from 'Edmund Scientific' mid seventies. Anyone knows the name of it ?
  10. Topic grading...

    Thanks. Perhaps could be convenient to consider clever topics brought to the table where only responders are 'recognized'. Seen several topics where the original poster is not 'compensated' What is the democratic way ? A poll ? -If the forum firmware allows starcounting-
  11. Alternating electrodeposition...

    Thank you, John. Good. Easy processes do not bring much merit. Plating to the correct percentages an alloy ideally is composed of, would then need different times or currents when a particular anode is switched on, to establish a proper recipe, right ?
  12. Hi. Are the topic ratings conveyed to authors reputation ?
  13. Hi all. What to expect from electroplating a 'target' metal with two (or more) different 'donor' electrodes cyclically switched on for few seconds ? I do not have the equipment to experiment. Example... an iron 'target' electrode getting electrodeposition from both submerged copper and tin electrodes in the same vessel but only one timely connected (powered) at a time... With proper timing; would the iron be electroplated with bronze ? Or... several 'donors' creating a complex alloyed surface for corrosion/hardness/properties improvements ? Does such a practice exist in the industry ?
  14. And the rest of the planet. Tried to find a link to streaming; only found the next airing, tomorrow ¿GMT? (and something in facebook, which I do not go.) ----> https://www3.nhk.or.jp/nhkworld/en/tv/documentary/201709290600/
  15. Today I saw a documentary program on television proposing politicians to be robots running artificial intelligence. It left me thinking...
