Do they have all the mainstream libraries ported over yet? When I last looked into them, they were new and half the libraries were still on the "to do" list.

I'm going to feed the children now... not sure who I'm going to feed them to.

For what I have needed to do with them I haven't found a library issue

There is not any surf to speak of on the east coast right now, but I will definitely take a long swim...SALT-WATER THERAPY

Surf... storm surge... tidal wave...

You just need to add a bigger Non-Anchor in your toys 10'+ of Mal 

Autumn is time to get back on the waves for me.

I will ride anything from body surfing to riding a fast food serving tray; body board, piece of plywood, 5'10" hybrid fish, squash tail, performance thruster, round-pin, and long boards out the ass... I had a sick quiver once upon a time. But it is March and the water is 50 F, so maybe a short swim, 10 mins, just to get the salt circulating again.

my man, "blueskull" sent me these as a thank you for the gifts I sent him. Pretty RAD indeed. I really needed a bench top microscope and the new 121GW looks insanely nice. The laser diode was a very nice surprise and what a treat to learn and play with...much love BLUESKULL!

[beanflying]

Nice additions  I need to upgrade my converted Microsoft Webcam at some stage but it sort of does what I need with larger SMD that I stick to.

If you decide to join the haters of the 121GW send it to me  Just bean playing with mine this afternoon 0.02% error against a 0.3% spec. at 35+C

@bean and @inverted reminds me of my 20s yr old obsession with sailboarding - 4 boards then, too many sails, never made a forward loop - gave it a shot though - owwwch.
I still have a 250litre racing sailboard and a 195cm slalom for flat water blasting - sails/masts/booms etc.
I am at 37 degrees south latitude - so in the winter the roaring forties come through - now I don't fit my wetsuit - don't they shrink with age? (nope - something else has expanded)

I tried my friend Lazlo's wind sailboard and nearly died. I can/have harnessed the ocean energy quite well but add the wind into the equation and its a different world.In my youth I traveled a lot to surf, not so much anymore, but I still tune into the WCT and the like to stay involved.

[VK5RC]

I can't surf to save myself, that flexibility to get up from lying to a surfing 'crouch' - my back doesn't do that!
The good thing about Windsurfing is that once you get a bit of arm strength and coordination - you use the wind to do all the work - including pulling you back onto the board - so it does get easier.

Take you biggest sail and build a Landyacht with it plenty of great spots North and South of you Either that or come play Kite Powered toys when it goes onshore and the Surf craps out. Me maybe 8-10 years ago in my former 'job' 

Job Description - Flies Kites and Plays With Toys, not much has changed just a bit less kite flying.

I am running ti side by side with the DMM7510 right now and will post the pics shortly. Seems good enough for the cost of the unit. at +35C, id be walking around buck ass naked trying to find a fan to cool my boys..

[VK5RC]

Looks like good fun, never tried kite surfing, I should someday but would need a lot of time to learn/strengthen up and gear up.
-I just loved flat water blasting - a 20knot sou'wester, the Goolwa lakes - 4 foot deep, freshwater and about a 1-2km 'reach' perpendicular to the wind, you hit high 20s occ 30+ knots, just the rear 2-3 feet of the board and all 14 inches of the high density fibreglass fin in the water. Lots of fun.

Niiiiiiiiiiiiiice!

There is a reason I choose not to upload videos of me Kite Surfing - I can but my board skills aren't great on one tack It can be a bit hard on the knees and if you get Teabag'd badly water can hurt 

Plenty of good Land spots on the Coorong Beaches and Salt Pans and also up North of St Kilda. The main beaches of Adelaide are great but to many humans to really let it all out. We did get North Haven closed for a Race a long while ago and I got the Buggy wound up to 93km/hr on one of the legs.

Rats! I guess I gotta wait longer for our meet up.  Oh well....have a safe trip!

Finally got a little more time for the 8656.

Pulled out the TDS220 and was able to see some sort of signal up to 350MHz, so that means the high band signal is working.  Scratched around and found a 50 ohm terminator and put that on one side of a BNC tee with about 600mm of 75 ohm coax going to the output of the sig gen.  Not ideal - but the signal levels were notably more consistent than when there was no termination. (Big surprise, not)

AND I got to transmit to an FM radio!  Started out with the internal 400Hz and 1KHz tones and while that was eminently successful, it just didn't satisfy.  I dug around and found one of the very first projects I made.  I still remember laying out the PCB design on a plane trip from Sydney to Adelaide to visit my great aunt (in my Uni days  ). This was a Wien bridge oscillator, complete with real thermistor.  Needed some switch/pot cleaning and a joint re-soldered.  It worked, but couldn't drive the sig gen.  The sig gen had an input impedance of 600 ohms and my oscillator had an output impedance of over 10K (by design).  Sigh.  Need a buffer amp added and re-housing - with a bit of cleaning up.

Looking for something with better output I grabbed the first thing at hand - my Galaxy S5.  Wired up the jack, cranked up the output only for it to decide it was feeding headphones and warned about excessive volume levels.  Sheesh!  Nanny state frustration set in.  I maxed out the peak deviation and got audible reception on the little FM radio.

Mission accomplished, albeit somewhat less than ideal - but I couldn't be bothered pursuing it any further.

Call me a nerd ... I've been running my oscillator against the 8656 modulation output in X-Y mode on the TDS220 for the classic 3:1 Lissajous figure.  (Hey, it makes me look like I know what I'm doing  )

Got a spare Type N - BNC male and female adapter going in your baggy too @brumby should make hooking up a bit easier.

Gah but then you have to bugger around with complex toolchains, IDEs, ST's HID thing, all that stuff and then spend ages reading about it and working it all out. That is waaaaaay too close to the day job.

My entire toolchain for AVR is stolen from the ass of Arduino package as it's nicely compiled in there and dumped unceremoniously in c:\dev\avr and added to path.

Then the build script is (sod makefiles for this):

Code: [Select]

@echo off
avr-gcc -c main.c -Os -mmcu=atmega88p -DF_CPU=1000000UL
avr-gcc -mmcu=atmega88p -o main.elf main.o
avr-objcopy -j .text -j .data -O ihex main.elf main.hex

Program

Code: [Select]

@echo off
avrdude -c usbasp -p m88p -C \dev\avr\etc\avrdude.conf -u -U flash:w:main.hex

Flash a damn LED:

Code: [Select]

#include <avr/io.h>
#include <util/delay.h>

int main()
{
DDRC = 0xFF;
while (1)
{
PORTC |= (1 << PC0);
_delay_ms(500);
PORTC &= ~(1 << PC0);
_delay_ms(500);
}
}

And that's it. Hardly any work for me. Which is how I want it. Debugger? Got an LED - that will do!

That is quite nice. Ah, good ol' main(). It looks more "normal" than setup() and loop().

Oh, that is brilliant!  Thank you.  It will!!!

Suh-weet, man! Closeup PCB porn in 3...2...1...

Here is some cool pics of the 121GW next to the 7510 as they measure the output of the 5440A; which is now for sale. Its SO NICE. Yes the TEA users who know can buy it at a deeply discounted price, if they'd like.
