Re: RAspberry Pi Did not See Windows Systems

I don't have any windows computers on my network so I cannot advise on that issue directly, but most difficulties like this have their roots in the network (router) setup or the windows file sharing setup on the other computers. Can you ping the router/AP and the other computer? That will tell you i...

Re: B+ Not Booting Anymore

With power off, remove SD card and try to reformat with SDFormatter (windows or mac) or gparted (linux). Reload fresh Raspbian or Noobs on the card and try again. If reformat does not work, get a new card from a reputable source and try that. Check with h2testw or f3 to be sure card is legit...count...

Failing a good reformat of the SD card, get a new one from a reputable source and check it with h2testw or f3 to be sure it is not counterfeit. Be sure it is 8 G or larger and class 4 or higher. Load a fresh copy of Raspbian on that and most likely, your Pi will boot normally.

[SOLVED] Java script a resource hog

Good suggestion. Thank you. I had disabled javascript in about:config to avoid loading still another plugin, but it wiped out too many web pages or prevented filling in data. Noscript allows normal web page viewing but keeps the offending scripts to a minimum. Thanks again.

Re: Pixel a resource hog

Yes, that is why I disabled it in about:config without adding another plug-in. See above:
After going into about:config and disabling javascript, cpu usage stayed below 10% after the initial load and the temp stayed under 60C.
It worked.

Re: WinSCP does not read homedir via Pi3 built-in Wifi

The most obvious problem is the short range of the Pi3 wifi. Try getting very close to the router or AP. Your router setup may not be supporting that access route and I can't help you with your router config but do take a look at it. There is also a chance that WinSCP may not play nice with the linu...

Re: I simply will not have HDMI TV, but LCD display and hots

Does your LCD touchscreen have a DVI input or is it one of the models for the Pi that uses the disiplay connector ribbon cable? Is your wifi hotspot your only access to the internet or can you connect an ethernet cable?

There are two main problems (at least) with the uSD card on the RPi. First, due to the popularity of the medium, the marketplace has been flooded with counterfeit cards.

A quarter of a volt should not fry anything if you powered the Pi via the normal plug and especially with what is probably that much voltage drop across the cable.
