Today, I just discovered the site 'PiShop.us'. This shop and the Adafruit site still limit quantities. I was able to buy 1 PiZeroW and 1 PiZero from Adafruit (quantities restricted to 1). PiShop only had the PiZeroW in stock and was also limited to quantity 1. Adafruit now offers USmail shipping for...

The 'best' ways can only be suggested by knowing the application. Distances between switch control groups, propagation speed, complexity(or management) and cost are the biggest factors.

Hopefully, the OP will give us some more details to play with

Using the mini network that Modbus RS-485 is not so trivial if it's new for you. But, any multiplexing effort will take some planning. I once had a project where we opted to use RS-485 between a host and multiple slaves. I don't mind giving you some pointers as you mull it through. Depending on the ...

raspi2fb allows the JavaFX output to the primary "DispmanX" display to be mirrored to the attached LCD display. I'll take a look at this, thanks. I've been avoiding investigating 'mirrored' solutions because I had imagined using a headless system, perhaps without X, to make some small turnkey devic...

What specific type of information are you trying to send to the secondary LCD? If it's just simple text and graphics primitives , you can just talk to the display directly using code like mine (https://github.com/bitbank2/SPI_LCD). I created simple C functions to draw text, rectangles and image til...

I've found a promising post here Is it possible to force Java to write all graphics output to FrameBuffer? that seems to be what I want. It points to this article Java: Graphics in Linux . While I chew on this info, I'm gonna post the 2 github repositories mentioned for documentation sake. Desktop/A...

I've tried viewing the Android sub in the 3 different browsers.

Is it broken or locked down?

I've developed using windows and most recently C/Asm on an embedded system using an LCD display with touchscreen. I thought it would be an enlightening experience to add an LCD screen to a raspberry Pi and use Java to create a small interface to serve as my 'Hello World' experience for this platform...

Just to add to your 'been there, done that' list. Experiment with F-RAM, and other useful add-ons.

I backed the $25 level to get a useful little interface board to tinker with.

Saelig was a good seller for me. I got my Rigol scope there - their donuts are good too !

I switch between the inexpensive Rigol and modest Tektronix at work. They both seem to do about the same job. The Rigol does have a nicer interface for viewing the buffer, which seems bigger than the Tek. The one I listed seems very much the same as http://www.saleae.com/logic16 . I would sure beat ...

Maybe they had seen the Motorola Lap Dock setup.

I got hold of one for $50. Nice 1360 x 768 LCD HDMI display with sound, plus USB Keyboard, trackpad, hub, battery with external charger and still extremely thin.

I'm looking forward to their protocol analyzer feature for decoding SPI or I2C. It's a pain to count the bits on a scope. Also handy for re-purposing small color screens from cheap devices. For example, $10 gets you a 128x64 color OLED screen, Lithium battery, TI processor w/flash and USB power sour...

The project has unlocked the 3rd stretch goal of colors. It will look even better.

Would someone be kind enough to post the flex cable specs. I see it is 15 pin, but is there a conductor spacing as well ?

All I2c devices need power and ground like anything else plus the SCA and SDA lines would make 4 required connections. The SCA lines all will connect and the SDA lines all connect to form a simple bus. The devices have addresses specified by the datasheet. The can be fixed and vary with part number ...

agreed, with Element14/Newark it was 3 days from order to delivery (in US)

good news / bad news Good: I received a reply to my order query 81xxx. It was a polite apology about the order status. It even had my order number included. Bad: They mention a problem with a group of orders in the 80k range that will delay fulfillment until the end of September. . . . with renewed...

I also ordered on June 20, #81xxx 9-week estimate. I ordered extra stuff from RS with the RasPi >> ONLY << for them to have a chance to make a little profit after giving us the privilege of obtaining a RasPi. I ordered one 2 weeks later from another source and received it in a week. Strange. I will ...

Hi,

I ordered a Pi, clear case plus other goodies with order number 811xx on June 20, 2012.

I've sent a few emails and received no replies.

Any words of encouragement ? ( the new schedule doesn't address the MIAs )
