Re: Internet share wlan0 to wlan1 and eth0?

Hello Marcus, I have a Pi 3 B with an added long range Wifi adapter. I have several 4G Wifi hubs with limited range. My current network has a Wifi router that assigns IP addresses on a local network. Some of the computers have fixed addresses. Some of the software on the computers reaches other comp...

Re: Pi as an Sd-card reader/writer

I like your idea for reusing the slot but my SD cards include full size SD cards from my camera. I need a USB SD adapter. There is a new format SD card connection with extra pins for increased speed. A USB adapter for the new format is only a few dollars and I can also use it on other computers for ...

Re: Things I never want to see on a Raspberry Pi

Stuff a kitten. Put blue LEDs in the eye sockets and a Pi in the chest cavity. Write a COBOL program to Flash the blue LEDs on and off like the old HTML blink attribute. Write a Java program to generate a meow through piezo speakers on the end of firewires so you can spread the entertainment out to ...

Re: Ways to reduce power usage?

The standby power on all the Pi models appears to be similar with none low enough for a phone battery/charger arrangement. A large solar panel on the end of a long wire would be my approach. Put the panel out in the sun with the Pi, sensor, and battery in the shade. The next step would be a digital ...

Re: PI-Zero as a Wireless USB Hub?

The Pi 3 Wifi has a limited range. The Zero works out as a lower cost starting point when you are going to plug in a high power USB Wifi device. From my experience, the Pi 3 Wifi works in a room and a high power plug in Wifi device works all over a large house and out into the garden. Do you need th...

Re: Would ORICO H727RK-U3-BK powered usb hub be good to use

The hub you mentioned had a 5 amp power supply and could work depending on what you plug in. The Pi boards are more sensitive to voltage drop than most other USB devices. The Pi will fail to start in a configuration where everything else powers up. My Pi will work on the power from my 2.6 amp hub if...

I want to share the Internet access from wlan0 to wlan1 and eth0. eth0 and wlan1 need their own address range to talk when the wireless Internet access is down.

Re: Raspbian Jessie (64bit) for RPi3?

My current projects start with Raspbian on a P3 for development then the microSD card is inserted in a Pi Zero for day to day use. The code would have to switch between 64 bit and 32 bit at boot time.

Re: Cinnamon on Rasbian and Pi 3?

I use and like Cinnamon. Cinnamon is heavier than MATE. I used MATE and LXDE back to back on Raspberry Pi 3. MATE is too slow compared to LXDE. Cinnamon would be worse. I am now looking at replacing Cinnamon with LXDE on some of my older computers. I also tested Xfce. LXDE is closer to Cinnamon. I f...

Re: Fails to boot after apt-get dist-upgrade

You can also expand the partition using something like gparted. There are stand alone gparted and Linux distributions you can load onto a USB stick then boot on any PC without using the PC OS. You then expand partition 2, the Ext4 partition, to fill the rest of the card.

Hello Dougie, The decrease in space used on the microSD card is significant if it results in a decrease in card size. Card size is a significant cost factor compared to the low cost of a Zero based project. I worked in the full version of Raspian, removing the things I do not need, and reduced the s...

A USB mouse or keyboard on every USB port will work with 2 amp. The instant you plug in a DVD drive or disk or anything else, you chew up big power. The Wifi connection chews up big power. HDMI requires significant power. 2 amp might work when you are not using HDMI or not using Wifi or have only lo...
