Re: A picture from The Pi Hut

Anyone who has done any sort of manufacturing will tell you just how hard it is. Witness all those Kickstarters that are heavily delayed or never get produced. The foundation is producing around 80,000 Pis a week. That's amazing in itself and the fact that they can do it in the UK at such a low pric...

Guide: Updating the firmware of a ESP8266 device from a Pi

I've written a couple of blog posts about how to use a Pi to update the firmware on ESP8266 devices and I thought I would share them here for those that are interested. The first is a guide to flashing the Pimoroni ESP8266 pHAT and the second is a more general guide of how to program a USB connected...

Re: WiFi Issues ? Start here !

Thanks to everyone that mentioned that connecting to channels 12 and 13 could cause issues. It's been a long term problem for me that certain WiFi dongles wouldn't show my access point in the list. This included the official Foundation dongle. Up until now I've just shrugged and used one that did wo...

Re: Raspberry Pi Zero audio outputs

I'm assuming that you are going to be using a GPIO display and so this might not work for you but this DAC is an option:

As for the WiFi Config, it's moved to an icon in the top right of the screen. It looks like 2 computers.

Re: What's a cheap & good way to get (better) sound?

Firstly how "bad" do you feel the sound output from the A+/B+ is? It was very much improved over the B. I've been thinking about building an internet radio too and so have been thinking about it. Here are my options for audio: You can use a DAC, but if you are using I2C for your display then you may...

Re: Pi Zero tested with Gert's VGA board

Thanks James. It was really an excuse to get my VGA adapter working.

It's one task I can tick off my lis...

Re: PI2 -- no gui wifi config

With the latest version of Raspian "Jessie", the WiFi configuration is an icon at the top right of the screen which has a picture of 2 computers on it. If you click that you should see your WiFi dongle. If Raspian can't find it then that list will be blank.

Pi Zero tested with Gert's VGA board

There has been some discussion about how The Pi0 should work with Gert's VGA board and as I have one of each I thought I would give it a test. I managed to get it working and it works pretty well:

If you mean under the "Product Information" tab ... They've probably just copy/pasted from the old B & A page - unless they know something we don't, which isn't beyond the realms of the possible. Hmmmmm, even with a copy/paste the current model A is not 66mm long. To me it does look like RS has the...

Re: Model A sold "only" 100,000 units - a flop ?

a. I'm very dubious that the RPF would go that route. b. I'm very dubious that it could be done for $35. Of course it's all speculation on my part, but I don't think it's too off the wall. As for cost. The 8bit ATmega CPUs are pretty cheap and other then that there is just some buffering and a darl...

The more I think about it, the more I feel that the question that should be asked is: "What does the A+ need to be to easily satisfy the dual role as a teaching platform from programming real time embedded systems and a useful "maker" board for use in embedded projects?" My answer to that is: "A boa...

I'm also very curious about the A+. It seems that speculation so far has been, a cut back board to the HAT footprint possibly adding WiFi or Bluetooth. I would also add that it could be a standard size Pi board with extra GPIO pins and possibly a second camera connector. I'm sure that those that are...

Re: Maynard/Weston/Wayland/X?

I have no idea how this manifests in Wayland. It possible that the message transaction cost is much lower, which could mean the problem, though still there (same framework and apps after all!), isn't as acute. What happens with X over Wayland is anyone's guess! The Wayland Wikipedia page says that ...

Re: Maynard/Weston/Wayland/X?

This is actually a design fault with GTK and QT. A lot of those messages are entirely unrequired. Especially mouse move stuff, where there are multiple unnecessary transactions. The suspicion is that QT/GTK tried to be too much like the Windows API. A lot of work was done by the Bitscope guys to op...

Re: Maynard/Weston/Wayland/X?

Well the video of Maynard looks good. The graphical layers are a little confusing even to the advanced user. So if I understand it correctly, the desktop Maynard runs on the Weston server, and Wayland is a bit of a red herring, being the protocol API. As for X, it seems that an X server could run o...

Re: I'm a little confused

The RasPi boards were initially designed to be profitable in batches of just 10,000. So the much larger economies-of-scale now in effect will have driven down the manufacturing costs significantly. How much of that gets back to the Foundation is obviously part of the confidential agreement between ...

The model A only has one USB port and no ethernet but draws ...
