Thank you. I read about that before. Hard drive transplants may be possible only to same brand/family compfusers... The Windows drives I tested were operating internally on that laptop years ago. They do not now with a USB adapter cable. How does this work then ? : Check the description at ---> https://www.ebay.com/itm/394048404931?chn=ps&var=662588638948&_trkparms=ispr%3D1&amdata=enc%3A1oPLEpymjQLWDqbY7bjZz-g51&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&itemid=662588638948_394048404931&targetid=1599090334937&device=c&mktype=&googleloc=9014268&poi=&campaignid=15275224983&mkgroupid=131097072938&rlsatarget=pla-1599090334937&abcId=9300697&merchantid=6296724&gclid=EAIaIQobChMIyL2jqK-U-AIVNcmUCR3MOgIeEAQYBSABEgIHdPD_BwE Buying a drive that has never been in 'that' laptop before, sold with windows activated to be installed on any PC ? Is that a new or Win10 only thinghy ? Is there some missing fine print like The receiving PC must have had before a Win10 OS ?

Thanks. Operating from USB stick is not to consider. Has to be hard/SS drives. Tried old Win98 and WinXP and Win7 hard drives and none booted. Blue screens and freezing. Which puts me to think if there is any truth in such 'special' cable that allows booting.

Thanks. Pulled my own cable out of the spider webs, changed bios to boot from USB; plugged another Linux drive disabling the internal and booted just fine. Submitting this post with it. Yes, only 2.5" drives are in the game. Next to try in a few minutes is a Windows OS drive. Will see... I do not know how to identify which of the 3 ports is USB 1, 2,3...🤔

Greetings. Went to a local computer repair shop to see if they had for sale any laptop with a side-removable/pluggable hard drive slot. There are some older ideal candidates but they had none of those for sale. Intention is to select which operative system hard drive to plug/boot from for the task of the moment. Mostly Win11 or Linux. The conversation degenerated into choices of -having two internal hard drives, -having one hard drive with two OS partitions, -having two PCs, -having two USB hard drives and plug the desired one, -having only one 'special' USB-to-hard drive cable to connect, boot and work with the operative system drive of choice for the task of the moment. [ USBport-----------------------cable----------------------internalharddrive nowasexternal ] He showed and offered me to sell such 'very special' cable apt for booting and available only as a tool for technicians for ~$35. When I asked about speed performance with that 'special cable' instead of reaching the internal hard drivel bus, he said 'no difference' What do you know about such 'special-for-booting cable ? looks like

Hi. People with historic generations living at high altitudes capture more oxygen in their red blood cells. Would a transfusion to a person without that extra affinity be transferred, at least temporarily ? Has it ever been tried to patients with deficient lung oxygenation ?

Had to happen some day... reading not from a book, but "online" (whatever 'online' means). Found interesting enough to share, many subjects of all flavors to choose : ---> https://www.lowtechmagazine.com

I suspect the waveform on the oscilloscope will be like And the speed of the magnet altering the amplitude, the strength of the magnet the time of the sweep, with other influences as gap dimension, size and shape of magnet, size and shape of bobbin, wire diameter, electrical load...

Just hold it in, fellows, one more minute !

Thanks. Yes, I need a part made and wanted to have a sense of which material would be convenient. I do not know if hardness is what I have to look for. 'Deformability' plus 'resiliency' to act as a seal/gasket between surfaces would make more sense 🤔 Gathering several different materials to evaluate how they perform under 5000 psi after CNC machined.

Was trying to find hardness figures for nylon, delrin, ABS, teflon, poliethylenes ... and got lost in too many scales Shore, Brinnell flavors, Vickers, Rockwell, and metric and not metric, Is so much variety needed ? No consensus ? Very nasty to see so many and looking for the proper conversion. 😱

Good day. Let me know if I learned it right : The color of the lens is the color of a laser the goggle does NOT protect. The color of the lens is the one the laser beam color can pass trough. The protection from a laser is by reflecting, absorbing or blocking the beam and which of the three cannot be told by the color of the lens. Goggles can protect against several laser wavelengths except the one of the lenses.

Interesting how the figures nearly coincide... ~400 to 800 THz and ~400 to 800 nm.

Hello. Blue plus red emitters are used as grow light. The resulting hue is the sum of red+blue. Or is it the difference ? If the sum; what color is the difference of their wavelengths ? And what is the intended meaning for 'full spectrum' ? (Image borrowed from the web)

Nostalgic enough, bought one of these lately : http://www.rccaraction.com/wp-content/uploads/2015/10/Mattell-Vac-U-Form-ebay.jpg

Hi. Similar situation yesterday... One judge decided to eliminate face masks against covid19. If hundreds of other judges do not coincide with that ruling against CDC; is it just ? In the event of future deaths due to the no-mask ruling, will the judge be guilty ?

Wilting of technology. Just to share.

The definition of justice I prefer says that - justice is to constantly and permanently impart to each one what is deserved - Is it just when only one judge of thousands decides to free/reverse/pardon someone accused of a crime ? Implies that justice is subject to personal opinions, not a set rule that fits consensus.

Hi. If the equipment installed cost is minimal, everything tends to work well for the pocket. The marketing of solar water heaters are made for the pockets of vendor and installers to be happier than the customer. Heating water from photovoltaics does not offer a good efficiency as the photovoltaic panels are only ~18% efficient; and heating panels at least triple that. Heating water differs a great amount on your location climate. You may need to shield the elements from wind and cold losses... or not, with a great repercussion in costs. Last year I made a heater for a friend in Florida and he cannot be happier. Installed in series before his electric water heater turned very lazy now. well/municipal water source ------->solar heater------->electric water heater------->house distribution The method I used very similar to 30+ metres thin wall black 2 inch cheap irrigation polyethylene pipe as :

Thanks. Yes, the ones that yield a pay for the process and leave some profit. Lithium is one good candidate.

Now am more confused than before. Common Na, K, Cl, Ca are not the desired elements to collect/deposit in the electrodes.

Hello all. Never had it fully clear, voids in knowledge... If a solution has -say all- the elements dissolved in water, and a direct electric current is passed in it; what elements will deposit on the electrodes if the voltage is 0.1V ; if it is 0.2V; if it is 0.5V; ... ... ... if it is 1.0V ? Can you cite examples for each voltage please, and which table tells it ? Electronegativity ? Electrochemical series ? Standard electrode potentials ?

Good day. Somewhere read that elements can be extracted from seawater by - Adsorption by amidoxime-based polymers -- what is that and where to source such ? - Electro chemical cells --- What determines ignoring/rejecting sodium and chlorine ions from the process and collect only other than those ? Any 'special' voltage to ignore Cl and Na ions ?

The companies that build the plexiglas separators for bank cashiers can surely do it. Probably cheap using leftovers that otherwise go to the dumpster. Edited - added. Just make sure anchoring properly the whole or the theft will include the clear safe box...
