Re: [SOLVED] Internet Sharing from Windows Laptop connected to Headless Boot ethernet

it's been a decade since I used windows for dhcp and internet sharing. But I seem to remember you could bridge the interfaces in windows so the pi would get info from same source as the laptop. Laptop would just act like a network switch. When I read your original post I was thinking the wireless is...

Re: [Resolved] Electrical noise if ethernet is connected.

I have seen 5 female jacks that were bad in 40 years. lightning strike blew back off the dsl modem, and went up the ethernet to my server and fried all 3 jacks on it. At least melted jacks stopped it from going any further up the network.

Re: Using 2 MAX31855K Thermocouple amplifiers

communication is on the same line. How would a second device talk at same time?
But if you swap top and bottom, I bet you find the top is the one not reporting. whichever gets the bus line is the one that will talk.

Re: Re-order the DPI pins

maybe you can use a parallel to serial shift register chip to spit them out in the order you want. After all you can input any line in to get the order you want out.

Re: How to control kgs zf90 with Rasberry PI like a remote control

you would have to sniff the codes transmitted then duplicate them. Then hope you never have to pair it again. Be easier just to bypass both ends. All it is is a relay to trip the motor relays (contactors). Pi is a bit overkill. I used an arduino to run my elevator. Unless your planning on it doing 2...

Re: Stripping out RS232 ASCII Characters

A simple piping script would take serial in, and output everything a-z or whatever you want to your program that wants it. That is what makes unix's so nice, you can filter before and after with a simple '|' pipe, and "<>"redirection.

Pi3 is not areal time OS, so your timing could be off from the beacon being busy with something else as well.

Re: Robotics Q. Arduino, Raspberry Pi, or Both?

How would weight increase? Are you pulling one of those inclined sleds they use in tractor pulls?
Newtons law of motion could apply if load is not stable causing tipping with sudden changes to motion though.

but for something that simple arduino would do it, and it is more real time.

Re: Will we ever see high density displays for the raspberry

All the chips needed to control the iphone 4 display are already IN the iphone4. start diagramming them so you know what you need to send to use it. Apple was nice enough to separate the display screen from touch control interface at least.

When you need to notify, just check the interface status of the wifi, if it is down, bring it up and send message. I would keep it down for security, and only bring it up to scream for help. Then drop it again. your only problem will be if the wifi is using the same network as your ethernet one. If ...

Maybe the excess heat is from the 32bits just sitting there. Once it goes 64bit they will flow instead of sitting there getting hot.

Re: Initial Boot problems - check keyboards

logitec k400r wireless works fine. I paid $8 on black friday for it. Wired is to close to tv when I have it plugged into it. Only time it hasn't worked is when I had the power switch off on it. Turning it on though solved the problem.
