Random device ID is familiar for me. I get that on some of my ATMega8 chips, and the reasoning is badly soldered chips (bad connections). Once I fixed the connections, they all began to work just fine. I also get the same problem when my USBTinyISP (or AVRDude) gets confused (I tried plugging in two so I could power two boards), and AVRDude picks up random Device IDs that change each time I ask it to check (even after unplugging the second programmer). I needed to unplug them both, close AVRDudess, plug in just one, open AVRDudess and try again and it was okay.

Unfortunately I find AVR chips extremely flaky! However I do like how easy it is to get up and running with them on AVR Studio (select the chip, compile code once, it gives you a makefile, never touch the IDE again and just use the makefile and notepad++ or sublimetext from that point onward).

It's times like this that I find I can only laugh at the markup of products in stores. These exact speakers, not of similar type, but these exact ones, model and everything. I pay around $0.18c each for them, whilst RadioShack charge $4! I know people need to create a markup to generate profit, but this is like 2,200% markup! Personally I find charging between $1 and $1.50 reasonable, and maybe stretch as far as $2, but no more than that!

This is just like Maplin here in the UK... some 5mm RGB LEDs that I got for around £0.02 each, they're charging £1.20 for!

The only question I have on this is if it allows you to handle vector images on Silk Screen or not? The one thing that Eagle is lacking is the ability to add custom images/vectors to the silk screen, and the only way to import than is to convert them to black and white mono BMP images, import them, pray they are the right scale, delete, tweak & re-import until the scale is right as it actually imports them as thousands/millions of individual pixels/blocks which cannot be grouped to move around and scale!
I have no problem paying for things, I do however have a problem paying for something that doesn't do the job half as well as it's free alternatives!

+Chris Holden I saw this and the only reason I thought of sharing was the yellow device I noticed on the third image! ;)

Learn to #solder big through-hole components and surface mount. How simple circuits work with NPN #transistors, how sound works, timer interrupts and even how to transfer data over #infra-red while also having fun!

Another fun project from one of the Makers (me) at the Build Brighton Hackspace in England. Any help I can get to promote this project would be really appreciated!
