Got one of these puppies a while back.

It is being used as a prototyping board for a work project, made necessary because I exhausted the capabilities of an ATMega328P/MCP2515 combination.  While the board is an excellent design and well-made, I should caution that it is not very "Arduino friendly".    If you are good with microcontrollers, and are looking for a challenge, this would be a candidate worth considering.  On the other hand, if you are new to uC's and Arduino, this cat would probably not be the best choice.

Diavolino:



It has a similar form factor to the Uno / Duemilanove, but since it doesn't have the USB chip it is cheaper than a Uno (around $US 12).

You program via FTDI cable (or the ICSP header). The ICSP header and the chip socket were not part of the kit. Since it doesn't have the USB chip or a power LED it would be suitable for low-power applications.
Please post technical questions on the forum, not by personal message. Thanks!

I order crossroad's book and another book on wireless network stuff to learn xbee.
Also ordered a dell computer from MS online store for my new year of contract work. Nice, ah?
One display corner has splitting open seam and the entire screen is warped (not flat). Supposed to be new.

Well, when I last time learned interrupts, I was actually a teen and I read a book, not web pages. I'll surely learn it again on paper!

Purchased and received: FPGA Development board https://www.sparkfun.com/products/11953 and/or http://embeddedmicro.com/development-boards/mojo-v3.html 

No plans for it - except to look at FPGA programming. (note the Sparkfun logo: Expert programming skills required ;) ) Theory is fine, but what does it feel like  :smiley-yell: ? ;) But with it the Blinky-LED programs can run incredibly faster. :D

Interesting, I got one of these recently:

I have a more substantial FPGA development board but its hard to integrate into a project.  CPLDs are easy to integrate, but they only take small designs.  This is easy to design in and takes the same sort of VHDL or Verilog.  Yours has a more recent chip, but its probably not more powerful for most purposes and is more expensive.  I like these relatively cheap solutions.  FPGA/CPLDs are fun.  If what you are trying to do is just logic, they are so much faster than microcontrollers.
I have only come here seeking knowledge. Things they would not teach me of in college.

How about Christmas, for those who celebrate?  Anything interesting?

I made out like a bandit..  BeagleBone Black from one of my brothers (who doesn't "do this sort of thing", so it was quite a surprise!), another older sibling gave me a nifty solar panel with Li-Ion pack for... whatever I want to do with it.  (I immediately connected it to the BBB.  His wife asks, "don't you use anything as intended?" referring to the cell-phone charging commentary on the box.  "Following directions suggests a lack of imagination," I replied.  XD)

But my better half really took the cake.  Out of nowhere, she risked her life and limbs to enter the spare room I sometimes refer to as my evil genius laboratory, dug through piles of stuff to find my tools, then looked online through maker guides to see what I was missing.  The result: a set of Klein wire strippers (one for 30! to 20 AWG, the other for 18 and up), a big pair of auto-adjusting strippers -- which is a lot of strippers, but seriously, I had been using those cheap crimper/stripper/bolt cutter things from the box stores, or a pair of scissors, or my teeth -- also, a set of Wiha precision screwdrivers and SMD tweezers, a 90-deg angle drill adapter (I had been complaining about tight corners on a subwoofer box I was building), and a Porter Cable oscillating multi-tool.  I was seriously impressed!  I had tool envy for my own tools.

I'll have to remember that when next time the wife asks why I won't stop to ask for directions.  ;)

Lady Nickity bought you, not one, but several strippers for X-mas?

I'm envious!

A new graphics card for the computer. So what to do with the old one (which had started to reset at random times - and couldn't cope with the requirements of SimCity's newest extensions)? Probably can reuse the fan - but with highperformance electronics parts are too specialised for much reuse.

Kathleen and Roberts book arrived today. Looks good, well done :-)

After a really very long time  of deliberation, I finally decided to buy a powerful regulated power supply (thus powerful for my modest needs).
Arduino Uno R3, Arduino Mega 2560 R3, Ethermega (R3), and some Ethernet Shields (R3), Chronodots, TMP36 sensors, DS18B20 sensors, LCDs/TFTs, RS232C to learn and play...

Very nice. Having an adjustable current limit on a bench PS can be a aid in troubleshooting equipment and new circuitry. Helps keep the magic smoke inside the components.  ;)

is it me or ....
The cover says 18V and the LCD says 19.0V  :smiley-eek-blue:
