I got a Panasonic GH3 last year.  Nice little camera, but turns out the body is actually the cheap part.  Figured I could use another hobby that demands lots of money.  Haven't enough of those yet, y'know.

Ah, good idea.  That would take care of all the surplus time and living space I have, too.  :smiley-sweat:

You can even die worried about who is going to care for your dependent adult when he/she grows up.
See how I nice I am to think of that?
Next week, how to clean a loaded rifle.  :smiley-eek: j/k!

Hi, just bought an ice maker, in WInter.
The wife has been in hospital for 4 weeks due to a fluid retention problem, put on 30kgs in 6 months, one morning woke up looked like she had gone ten rounds with Joe Frasier. Eyes almost closed due to fluid, all the while her doc had been treating her for dietary problems.
Off to hospital in ambulance, they treated her, lost 30 kgs in 4 1/2 weeks, fluid tablets, lot of fluid tablets.
They found she has bad heart, been bad since she gave up smoking 20years ago. So she has to give up Diet Coke, she will only drink ice water, hence the need for an ice maker.
Had to hunt for it, local shops didn't have any, one shop did try for me, to see if any in warehouse.
Ended up getting one on ebay, from local state supplier, $239.00 down to $105.00, included courier delivery.
Nice unit, works well, just got to get used to the clatter of ice cubes into the storage tray ever so often.

Playing around with PSoC... Just got a couple in and working through the learning curve.  So far, impressed... Completed the UART & LCD tutorials and will be trying out some of the analog modules.  GNU compiler is C++ capable but default GUI is configured for C.

I am a total plonker sometimes. Most of the time probably.

I bought 3 of these opto-interrupt thingies yesterday. You can see in the pic there's a plastic locating pin in one corner- I thought that was a moulding error so I snipped it off.

But unfortunately in the process of that snipping I also cut one of the connection legs off, perfectly flush with the housing.  =(

Well, they do say you should buy spares....
My hovercraft is full of eels.

No PMs for help please.
DO NOT power servos from Arduino 5V: give them their own power and connect the grounds.

For that price, I'd roll my own.

I have a small bag of those. They are everywhere in printers.

Yes, you should.  You'll use them eventually anyway!  But, in the meantime, surface-mount that puppy!

TI Connected Launchpad: http://www.ti.com/tool/ek-tm4c1294xl
Several Cypress PSo4 Things, including some bare chips ($1 each!)
   Pioneer: http://www.cypress.com/?rID=77780
   Prototyping kits: http://www.cypress.com/?rid=92146 (what a great idea, as a "sample" alternative!)
I also scored an ST F4 "Nucleo" at EELive:  http://www.st.com/web/catalog/tools/FM116/SC959/SS1532/LN1847/PF260000
So many eval kits, so little time :-(



I ordered the $4 Cypress 4200 prototyping board.  It worked nicely, but no debug without the $99 dongle.  But, the 4200 Cypress Pioneer board w/ the Arduino-compatible headers is only $25.  I received mine last week and had some quality time with it this weekend.  I'm very impressed.  The 4200 has the 32-bit Cortex M0 core, 4K of SRAM, 32K of flash no eeprom but flash can be substituted easily... yes, user software can write flash!  Code can execute from flash or SRAM!

The PSoC Creator GUI, Compiler (GCC), debugger, and kitchen sink are all in the one package - free.  The debugger works great on the 4200 Pioneer board thanks to the PSoC 5 which is acting as the USB-serial bridge and the debug interface.  Code seems to compile well for speed and small code size.  The compiler and linker can have user-supplied runline parameters set in the GUI as well as lots of customization.  A++ on the effort.  The learning curve is a bit steep, but it may be just me, too.

For $25, the Pioneer board is a must have if you want to do some mixed signal work on a single chip for cheap.  The code developed on the Pioneer can be loaded on the $4 PSoC 4200 prototype board via the serial-USB bootloader - Caveat, the bootloader does take flash and SRAM, so if you want to avoid that, the 4200 'chip' is $1 each any quantity or you can purchase the Programmer for $99 and do anything.

I compiled a simple PSoC 4200 program with an implementation of the ILI9340/9341 TFT SPI library and the stats were:
Quote
Flash used: 14142 of 32768 bytes (43.2 %).
SRAM used: 1688 of 4096 bytes (41.2 %).


The above included the TFT driver library with 20 screen functions, one font, and the main() startup and initialization for the 2.2 inch display with a few lines of graphics.

Oh, the 4200 has a 48MHz system clock!  Sweet for the price.  In my book, this is a buy if you have the patience to read and watch a large number of training videos to jump-start your activities.

I just received my Tiva C-Series TM4C1294XL evaluation board from Texas Instruments. It's the Connected Launchpad version.
See how it goes.

Too bad TI doesn't sample that part (TM4C1294NCPDT).  I don't see why, it's only a $8 part.  I'd rather build my own board.  Using theirs seems like cheating...

I recently purchased a new BeagleBoard Black, and a little pile of transistors for a project I'm working on.

I haven't fully wrapped my head around the Beagle yet, but it's a neat little gadget!

I don't know what you paid for those transistors, but as a word of advice, stay away from NTE anything.  They are overpriced relabeled generics.  NTE261 is an NPN power darlington.  TIP142s would be a generic common replacement.  You can get these very cheaply on eBay:
