The 2nd time I did this I used tweezers as a heatsink for the cable. I need to get a small hemostat for this kind of job. Time to pester the next best pharmacist! I will enjoy the inquisitive reaction: "What do you need THAT for?" The same thing happened when I wanted some syringes with needles. Of course I needed them for dispensing a liquid. Is it my fault that they don't sell un-sharpened needles?

This is what you get when you try to do two completely unrelated things at the same time. Total confusion. When I still had a TV a couple of years ago, I once "lost" the remote. I found it in the freezer. Yes I was eating ice cream before. This time I ended up in the bathroom and noticed something of importance was missing and had somehow escaped from the grip of my hand.

Just testing if the latest change to the schematic of a project really works. It does. Unfortunately now I have to patch some libraries as well. Otherwise there is a beat-note in LED brightness due to unsynchronized PWM interaction. Fortunately I don't HAVE to use the PWM functionality of that pin, but I could...

The banana connector is a bit strange though.

It grips quite nicely.

Reminds me of Donald Duck. Don't ask my why.

Shipping took a bit long from the Ukraine, but that's the usual customs penalty one has to pay. From reading the makefile of LUFA I was initially prepared to have to reflash this thing with a hexfile that works with avrdude + libusb. HOWEVER, it worked with avrdude 5.11 right away (on linux)! AvrStudio 4 could talk to it too. That's how things should be. The nice thing about this one is that it can supply the target with either 5V (ATtiny, ATmega targets) or 3.3V (ATxmega). Once I get my ATxmega board ("BreadMate XMega PDI" by by Batsocks ) I can test if PDI programming works too. Programming speed in ISP mode (avrdude -c avrispmkII -P usb -B 1 ...) is surprisingly fast compared to my usbtiny.

Now I'm absolutely certain that I will NOT use this to power any micorcontroller projects anymore without massive precautions. My AVR ATmega chips seem to have survived this treatment so far, but I will NOT power the ATxmega boards with this thing directly. This cries for an additional voltage regulator + Zener diode just in case. These spikes happen when turning on the output of the power supply (switched by relais). I haven't tested if any overshoot happens when pressing the voltage-increment buttons. It would be quite sad if changing the output by +-0.1V would create spikes.

Still withing tolerances for 5V AVR chips. Lucky me! But I didn't have 'peak detect' turned on, so maybe there are some nasty spikes hidden in there. Better use a voltage regulator + 5.5V Zener diode in the future.

Now I can swap it without any trouble.
