Is this actually emulating AVR? Cool!
[QUOTE=HeatPipe;39819022]Is this actually emulating AVR? Cool![/QUOTE] It can simulate an 8086.
[QUOTE=voodooattack;39820505]It can simulate an 8086.[/QUOTE] Try a 6502 now :v:
Yesterday we tried screwed around with OP AMPS and EKG. [img_thumb]http://filesmelt.com/dl/IMAG1100.jpg[/img_thumb] me on the left The amplitude on my heart rate considerately increased as good-looking girls entered the rooms - we have yet to discover the connection to this.
Today I had a full day of interview with Rolls Royce for a graduate job with them. Scary stuff.

And the moon is aligned in such a way as to please the AVR gods [editline]7th March 2013[/editline] also working on a system to unlock my door from the inside using a keypad. I haven't posted here in a while but University has been pretty busy. Currently working on a system with 4 other people to detect a fall of a person (think elderly people) and have it send a text message + email to someone assigned to look after said person. It's the project we've been assigned by the Uni and given less than a week of proper construction time. Very stressful, very fun
[QUOTE=Trumple;39826572] Plus Avrdude seems to only work on a good day. When the sun is at 45 degrees. And the moon is aligned in such a way as to please the AVR gods[/QUOTE] But at least it works with a 5 quid USBTiny straight out the box, no jumping through hoops like AVR Studio. That's a noble project you're working on though, best of luck!

Anyone knows where one can buy a beefy UV laser diode without getting ripped off (and protection glasses)?
I've never had any sort of problem with AVRDude on any machine, what are you guys doing wrong? :v: tend to use an arduino as an ISP mind.
[QUOTE=DrLuckyLuke;39829523]AVRDude is a nice tool, if I weren't using AVR Studio, that's what I'd be using. You only have to configure it right.[/QUOTE] mmm maybe it's the lab computers then. They never like talking to the JTAG programmer! After that's setup it's okay, but I still love the GUI based fuse settings in Atmel Studio

Use a UV laser to etch pre-sensitized PCB's on a RepRap that's been retrofitted with said laser instead of it's print head. Permanently lock the Z axis in place, and use it to toggle the laser on/off instead.

You could try using just regular UV LEDs and focus them as a good outliner for some PCB UV Photoresist.

It's not really UV. UV wavelenght is abit shorter than 400 nm or even less.

[URL]http://en.wikipedia.org/wiki/Ultraviolet[/URL] I've seen plenty of lightboxes made with ordinary LED's with the same wavelength as that UV laser diode. They require a little bit more time to do their work, but they'll still get it done fast. Even seen someone exposing PCB's with a cheap lightbulb meant for people with winter depression.
Does anyone know where would be a good place to order the Rigol 1052E in Europe? I'v checked baxtronix.com but they seem to be out of stock for these.

Not good. My local electronics store has the 1052E but it's 470$ with discount ( 854$ without, lol ) and the warranty is 2 years compared to the 3 years for baxtronix.

Fuck, now they want touch-screen TFT because it's [URL="http://www.mikroe.com/add-on-boards/display/tft-proto/"]affordable[/URL]. I brought this upon myself for suggesting this for another project.
Dealextreme seems to have added a new "Rigol" oscilloscope to their catalog, [url]http://dx.com/p/rigol-ds-1072u-5-6-lcd-70mhz-512kpts-500ms-s-2-ch-digital-oscilloscope-grey-3-flat-pin-plug-191981[/url], 70MHz and half the sample rate of the DS1052E (which can be modded to 100MHz) for 25 euros more :v:. Can't seem to find any information about it on the Rigol site either.
I'd say it's fake, there is some signs of the label being edited in the picture.
