- several PCBs custom made by the usual suspects from Shenzhen
- resistors, pin-strip header, capacitors...
Project a): A small breakout board, SMD and DIP (not shown), for a very affordable LED driver (MBI5168), that can easily be used with the 'shiftPWM' library. It's a bit late for Halloween, but might come in handy for other quick and dirty illumination jobs. Up to 100mA per channel is possible if you keep an eye on chip temperature.  Project b): Add-on wing for the openbench logic sniffer by dangerousprototypes. As well known floating inputs pick up all sorts of noise, either from neighbouring channels or from thin air. This little board makes it very easy to select pull-up or pull-down resistors and choose from three pull-up voltages (2.5V, 3.3V and 5.0V). It is split into two banks, so you can work with common 5V signals and low(er) voltage ones at the same time. The individual resistors shown in the photos will be replaced with resistor networks once I've zeroed in on the correct values.

Audio, Video, Disco from iTunes (by Justice)
Keeping all possible expectations based off of † aside, it is an awesome album. (listened to it straight through right after I downloaded it)

5 watt output 40 meter CW (morse code) ham radio transmitter board kit to mate up with my recent receiver kit. In parallel I'm working on a DDS module under a standalone arudino chip for frequency control of this project. http://www.kitsandparts.com/qrp_amp.phpLefty

Attended "ARM Techcon" at the Santa Clara Convention center. ( http://www.eetimes.com/armconference Free exhibits pass + vendor classes (I went to NXP sessions on their new M4+M0 chip, and their USB-in-rom library) + 1 free seminar (in my case "A Close Up View of the ARM Cortex-M Processor Family – Under the Hood Architecture..."; to get a better idea of the differences between CM0, CM3, and CM4 chips.) Scored an LPCExpresso Board for an M0 USB chip (LPC11U14) and an STM32F4-Discovery board. (so many chips, so little ... focus.) Found the panels and the exhibit floor conversations generally interesting and helpful. Missed the "Rasberry PI" booth; when I was there they were filming This Report preventing me from poking at it... Also purchased from eBay 50 "Yellow LEDs pre-wired with resistors for 6V", with the idea that I'll be able to just plug them into Arduinos (and etc :-)) without having to dig up protoboards or resistors or whatever. I've got plenty of LEDs and resistors and protoboards and solder, but I guess I'm getting lazy in my old age. (I recently implemented digitalWriteFast() for chipKit, and found the idea of testing 44 to 85 outputs really daunting...)

The STM32F4-Discovery board is building up a lot of interest. Missed on free web give away with being on a different continent :-(

I just got this in the mail: https://www.adafruit.com/products/462This is basically just a prototyping board with a ZIF socket. I haven't assembled it yet so I can't put in a photo. The idea is that you can use the "Arduino as ISP" concept without having to muck around connecting up half a dozen wires. Just drop the processor into the ZIF socket. Quite neat. Pretty reasonable price, for $17.50 you get the board, the ZIF socket, an Atmega328P chip, and a few assorted extra parts. http://evilmadscience.com/productsmenu/tinykitlist/231I've got one of these that I use with an Adafruit USBTinyISP that does the trick nicely, but am always looking for a better way.

This:  You get to the stage where, if you hold things close they become blurry, and if you hold them too far away, the writing is too small to read.

Uh oh! This thread is getting a little lonely... Time to wake it up.
I bought: 10 x 16 pin dip sockets 100 x 50k resistors 50 x 75k resistors 50 x 43k resistors 100 x 2n2222 transistors
all off of ebay... and payed like $15 for it all, shipped...

I have all the lead I need, in the form of ammunition. For when ever the government thinks they want to take my gold and silver from me.
I thought the gold was all taken, taken to Fort Knox by order of one US president some 70ish years ago. I don't know if there's still gold in the fort or not

Instead of Ruggeduino, a few extra 328 chips. I bought german dark aluminum powder. Better than Gold for some things...
