Gertboard -- Alternate View
A quick look at the rapidly expanding Arduino project base will show the versatility of the Gertboard. Additionally, a ROHM BD6222HFPmotor controller adds 18V @ 2A port for motor projects. There is also a 2-channel 8-, 10-, or 12-bit digital-to-analog converter alongside a 2-channel 10-bit analog-to-digital converter. To top it off, 6x open collector divers capable of 50V @ 0.5A, 3x push buttons, and 12x buffered I/O makes this expansion board a solid choice for those who want to take the Raspberry Pi beyond casual.
 
The Gertboard can be picked up for $49.99 at Newark/element14.com.

Re: Production applications of Raspberry Pi

Patrick,

Given that this is put out by a non-profit organization and the Broadcom data sheet is not available, I would be very leery of using RPi in a production scenario. Better to use something like the Beagle Bone from TI where you can be assured of getting the boards you need as well the information to resolve any issues.

RPi may become a victim of its own success in that some of the companies donating the chips to keep the cost down may decide they have donated enough. Also did I mention that Broadcom refuses to release the data sheet?

It is really a workhorse being developed by electronics community

This is really a very good collection of the possibilities demonstration by Raspberry Pi. To my best of knowledge this will be really a very helpful article for the students and learners for designing projects using the modules. Yup many will be able to participate in further development of the vast possibilities.

Here's another useful RasPi board I've come across, though I haven't tried it myself.  Guzunty Pi is an "I/O Extender" board using a Xilinx XC9536XL or XC9572XL CPLD.  It's actually sold as a kit, with a 44-pin PLCC socket for the CPLD and through-hole components for easy assembly.  You can download various CPLD images for common I/O configurations, or program it yourself using free-as-in-beer Xilinx tools to perform any function you want (that fits in the CPLD).  Board is GBP 2.60 plus shipping or GBP 10 plus shipping for the whole kit.

The article misses one of the most capable io expansion card. http://roboteq.com/i-o-expansion-cards/rio-smart-io-expansion-card-for-raspberry-pi Demo video at http://youtu.be/cFqNjndLtqg And the kickstarter project that made it happen http://www.kickstarter.com/projects/95547492/smart-io-expansion-card-for-raspberry-pi

I kne w about Gerf but have only seen a few of the others.

 

I've had good luck with thisone: http://awce.com/gp3pi.htm

 

A lot of high level basic stamp like functions. Works with stuff other than pi too.

 

Great post.

IT would be an entertaining activity to build a stand alone data acquisition system. Use the tank as a motor, Battery, attach a robotic arm, and have the Gertboard ready to measure stuff. It could walk around and pick up soil samples, test them, send the data wirelessly, and move on...

Re: Portable Screens

the easiest option is to use a rear view mirror screen which takes UHF video from the PI. You can get these through eBay for $30 or so and take very little work to connect to the Pi (and no software). You can then tweak the Pi video settings to perfect the alignment to the screen. This gets you VGA level graphics. The only pain is these are designed for 12V (to be run from a car's power system) but some variants actually are 5v inside and with some bravery you may be able to steal that from the Pi connectors too.

Early days of the next generation

This really reminds me of the days of the Apple II, Kim, IBM PC, and others. People were doing interesting things with computers that provided them the control that they wanted over their tech. The only difference is that the last generation is not saying silly things about how these computers are too small to be useful.

I see this generation creating a new set of technology building blocks that are going to challenge the Microsofts, Apples, and Googles to keep up. You don't like what they are offering? Build your own version the way that you want it. 3D print the mechanicals and assemble your own control systems for it. Computers used to be mysterious boxes, but now they are familiar technology. Embedded systems used to be mysterious as well, but the free tools now are better than what we paid a lot for not long ago and the technology is much more accessible. I've got to wonder what the next wave will be like...

Good question Patrick - I know of some Kickstarter projects who have taken it into production, but not in large quantities.

It's great for small projects and the variety is fantastic. Has anyone taken the Pi to production in a real-world, high-volume application?

michigan0 Sang Kim First, 28nm bulk is in volume manufacturing for several years by the major semiconductor companies but not 28nm FDSOI today yet. Why not? Simply because unlike 28nm bulk the LDD(Lightly Doped Drain) to minimize hot carrier generation can't be implemented in 28nm FDSOI. Furthermore, hot carrier reliability becomes worse with scaling, That is the major reason why 28nm FDSOI is not manufacturable today and will not be. Second, how can you suppress the leakage currents from such ultra short 7nm due to the short channel effects? How thin SOI thickness is required to prevent punch-through of un-dopped 7nm FDSOI? Possibly less than 4nm. Depositing such an ultra thin film less then 4nm filum uniformly and reliably over 12" wafers at the manufacturing line is extremely difficult or not even manufacturable. If not manufacturable, the 7nm FDSOI debate is over!Third, what happens when hot carriers are generated near the drain at normal operation of 7nm FDSOI? Electrons go to the positively biased drain with no harm but where the holes to go? The holes can't go to the substrate because of the thin BOX layer. Some holes may become trapped at the BOX layer causing Vt shift. However, the vast majority of holes drift through the the un-dopped SOI channel toward the N+Source,...
