maybe you're referring to bi-directional level shifter?

this looks useful but the screen i have takes up two of the gpio pins for power

Thanks for the helpful responses. I got something up and running with x11vnc last night while waiting for my question to be posted, but I'll give the RealVNC set-up a try too. RealVNC is my preferred choice as I get to view what is being outputted by the HDMI port, and comes pre-installed in Raspbi...

to be able to use your $9 speakers... first you need a good DIY encolsure...then... 1. get the Pimoroni pHAT Beat, insert to your RPi's GPIO, attach speakers to the pHat Beat, load drivers, done. 2. get USB sound card and insert to USB port, get DIY amp (PAM8403 or better) with enclosures and access...

For your high temp problem, which also happened to me this is what I did. 1. installed a 25x25x6mm heatsink on top of the SoC, and a 9.5x8.5x10 heatsink for the USB chip 2. modified the official red-white case by making a square hole 26x26 mm directly on top of the heatsink 3. glued (yes just ordina...

Next up: Pi3B+ LAN-based ad blocker.

Oh, this one too I have next in line ... but using RPi3B

Happened to me too

tried 4 different card readers on the same card, no effect

examined the microSD card itself, specially the contact pads, there was some sort of contaminant on the pads
cleaned the contacts with contact cleaner until shiny
popped it up again
works

How my RPis are used (at the moment). Maybe you can apply some from the list below: 1. as Desktop PC and Web browser PC (RPi3B, RPi3B+) 2. as Home theater player using autoboot Kodi (RPi3B, RPiZW) 3. as Music player via Volumio (RPi2B, RPi3B, RPiZW) 4. as low power torrent box using Deluge (RPi1B+) ...

Got 1 RPiZ with USB dongle connected to the WiFi router.... no problems so far
Got 3 RPiZW connected to the Wifi router.... all systems green!

3 were all installed using NOOBs, one is microSD card transferred (by mistake) from RPi3 and it worked well.

Hi, This has probably been answered a 100 times, but since the process keeps changing, I need help. What I've tried: 1. Downloaded the newest raspbian image from this website and extracted it so I get the .img 2. Flashed the .img onto my external hard drive using Win32DiskImager and confirmed parti...

Booting via SSD without microSD card in slot will definitely work, although as pointed out in one post here, polling process seems to be eating CPU time, so the current work around for that is to populate the microSD slot with a blank (either non-formatted or FAT32 formatted) card. A permanent solut...

Thanks gonna try that, never tried a wifi dongle in raspberry before. All my RPi A+, RPi 1B, RPi 1B+, RPi 2B, Pine64, and Odroid XU4 are connected to the network via WiFi dongles. Didn't even edited any of the configuration settings to connect those to the network/WiFi router. I used (and still usi...

Cannot SSH because the IP address of the RPi changed when you installed the new WiFi Dongle. Steps you can do: 1. If you can directly access the RPi via monitor, keyboard, mouse, run ifconfig to get the new IP address of the WiFi dongle (could be wlan1) 2. If you have access to your router, check th...

I have read that the Pi 3 will not power a SSD drive You are misinformed. I've successfully booted my RPi3B from a 2.5" 1TB HDD via SATA-to-USB3.0 adapter cable...HDDs are more power hungry than SSDs.... No external USB hubs were used. No problems so far. PSU is 5V 2.5A. On my separate setup, my mu...

I upgraded all my "loaded" Jessie to Stretch, using the following steps: 1. Made image backups first...just in case (I heeded the warnings) 2. Accessed the target RPis via RealVNC and/or SSH (PuTTY) 3. Modified the repositories and upgraded as stated in https://www.raspberrypi.org/blog/raspbian-stre...

I never took chances as the we have high ambient temperature here so I installed heatsinks for the SoC, LAN chip and Memory and placed it in a fan-equipped case that I have modified to for efficient air flow to the heatsinks. My target is to get the temperature reported by /opt/vc/bin/vcgencmd measu...

On my Raspberry Pi Zero W with gpu memory set to 256 (though 192 is already sufficient), I installed Kodi over Raspbian Stretch with Desktop. Configured it to automatically load at boot. All files are accessed (actually "can only be accessed") via samba shares from windows and other RPis/SOCs. Curre...

Looks like there are currently two ways to avoid the card polling and high kworker cpu usage. Using newer sdtweak.dtbo from github issue linked above and adding one line to /boot/config.txt dtoverlay=sdtweak,poll_once This marks the slot as non-removable which disables any polling for changes. If I...

Is it possible to run Kodi inside Raspbian or another OS? Also, what would it take to have it default to bluetooth keyboard and mouse after setup? Thanks for any help ;) One of my RPi3B is setup as a desktop, with a 21" HDMI monitor connected to the network via WIFI. OS is latest Raspbian Stretch i...

Just a few quick questions. Was that on a Raspberry Pi 3B or 3B+ ? Raspberry Pi 3 model B V1.2 ... and when you say 1 extra FAT or EXT4, do you mean that the Pi is creating an additional phantom partition on the microSD that was not there originally ? If so, that seems very strange doesn't it? I wo...

Upgrade from Jessie to Stretch, this took me 4 ~ 5 hours long for one RPi3B with 32GB microSD.

Flashing the latest Raspbian Stretch image then re-installing your favorite packages (if those are only a few) might save you a lot of time.

Just an update... 2 days ago I posted that two 2.5" HDD enclosures failed booting an HDD with freshly flashed raspbian image in a Seagate Barracuda 1TB HDD. These were: 1.

I figured this is more a noob Q But I have a small army of Pis, and once I get a Pi the way I like it, I typically just dd it back to an image file on my Mac. Problem is they are *huge* Full 16/32GB of the SD card. So you've got the same problem that I have...and still looking for viable "simple so...
