Re: New RPi Zero W - with Wifi and Bluetooth

You can also get some OrangePiZero for less than $8.00 including shipping, but no BT. IMHO (well, as humble as I can get), anyway you shake it, Bluetooth is easily worth $2. Just having a BT connection for a keyboard/mouse is extremely handy and avoids having to have a USB-serial adapter connected ...

Re: New RPi Zero W - with Wifi and Bluetooth

For reasons I wont bore you with, I have been looking at open source android builds recently, and I came across a LineageOS ( Open Source Android) build for the RPI 3, which works quite well, albeit a bit slow. <...> Roger, I'm sure you know that the Raspberry line of boards are quasi-Open Source; ...

Re: New RPi Zero W - with Wifi and Bluetooth

The founder of the local makerspace Arron Newcomb just wrote a book for Arduino users who want to use Linux on single board computers such as the Raspberry pi. It is called Make: Linux for makers ISBN 9781680451832 http://shop.oreilly.com/product/0636920031338.do Thank you. I'll check it out. This ...

Re: New RPi Zero W - with Wifi and Bluetooth

Had to get a mouse out as the touchscreen was hard to use. Needed a keyboard to type commands in. I was able to run a java app. Been there! Having a USB mouse and USB keyboard within reasonable reach is absolutely necessary with the Raspberry line. For days, I would go in the junk closet, grab the ...

Re: New RPi Zero W - with Wifi and Bluetooth

The RPi Zero & Zero W are devices that are remarkable interesting due to the $5 and $10 U.S.D. pricing respectively. Here in Atlanta, two MicroCenter stores have the usually in stock, limit one (1) each per visit; so, a Zero & Zero W can be purchased once per day, stock permitting. Last week...

Re: Including binary libraries - experiment in teaching

<...> I'm wondering how to do this within the Arduino IDE. Its usual mode is to have all source code available, but that would defeat my purpose. I suppose I could create a bunch of alternative 'target board' builds, but is there an easier way? Any suggestions? <...> From my (very) limited understa...

Re: massively parallel stm32duino blue pill

The $5 per node RPi Zero is the least expensive commercially available microprocessor per-node implementation I have seem built into a cluster. The implementation is facilitated by the fact that the RPi is a Linux SoC board. http://hackaday.com/2016/01/25/raspberry-pi-zero-cluster-packs-a-punch/ For...

Re: Help on SD transfer with DMA

<...> Is there a better way to accomplish this? <...> So you do not state the total number of synchronized nodes, but for the sake of argument, let's say that it is a reasonable number, maybe 12 or a baker's dozen at 13. This means each node is manipulating SD Card data, that is, there are 13 cards...
