Re: RPi3 Bluetooth and Wifi don't play well together

Just wanted to add an update following some experimenting I did recently: I have two RPI3's purchased at different times and running the version of Raspbian that was current at the time so one has Jessie and one has been upgraded from Jessie to Stretch. Both get apt-get dist-upgrade every so often a...

Re: RPi3 Bluetooth and Wifi don't play well together

I have 2x RPI3 and recently bought bluetooth keyboard that allows multiple pairings which can be manually switched between, so I set it up with both Pi's. It worked fine, then I tried out a couple of bluetooth speakers on only 1 of the Pi's. It started getting the bluetooth and wifi dropout problems...

Re: Another lots of headless pi's thread. Load balancing.

Why would you need a load balancer? I presume you are intending to have each RPI present its desktop using VNC? If that is the case then each RPI would have a 1 to 1 relationship with the PC being used as the VNC client. So there is nothing to load balance. If you are looking to host multiple deskto...

Re: Code Club age question

Yes you can have a different (older) age range, as ultimately its about ability and prior knowledge. Although they might find making witches and ballerina's move about the screen a little "childish" I have no idea what CodeClub's current approach is to clubs in other countries or how you would acces...

Re: Flash Player now available for Chromium

We'd much prefer to offer Scratch 2 as an offline application, but it requires Adobe AIR to run on the target platform, and Adobe withdrew support for AIR on Linux around 5 years ago. Nothing is ever simple :D I had been running on the mistaken belief that if it used Flash in the browser it would u...

Re: Raspberry Pi Won't Boot, Red Power Light Only

In the end I had to replace the SD card slot to fix this problem. After modifying the original slot by bending the contact pins they snapped off after a few days of use, so I have soldered a more sturdy card slot in its place, it has a metal back to it which stops the card bending under the force of...

Following advice on here if you squeezed the card against the socket it worked but when you let go it stopped making contact. What I n...

I find this an interesting discussion: If I understand correctly, Gordon now programs an EHCI driver in VPU code. Is that hard- or software? Well software/hardware can be a blurry business... Things like FPGA's start messing with the normal boundaries, as you can just load a processor and other sys...

@Gordon - why does it work for me? It even worked with the 1.1 mouse on the 2.0 hub and the 2.0 keyboard on the Pi. Those devices just cannot be mixed on a single hub. I even have a weak setup currently with the Pi also powered through the hub. I think you probably just got lucky.... computer greml...
