General discussion / Re: Big Box of Parts
[quote author="erdabyz"]I was thinking about taking out the heaviest stuff, but it happens to be the coolest stuff also...[/quote]
So just take it out. rules say you should take out the parts you like and put in whatever you have lying around. It will be nice if you do something with the heaviest stuff and show us.

Project development, ideas, and suggestions / Re: Nokia LCD Breakout Board for uC interface by easy compon
Hi hmms,

I assume your working voltage is 5V, then you just need to install the voltage divider (resistor based) in the data and supply lines(as they are 3.3V lines). And for the LCD backlit where 6.8-7.0V is needed, you can try the other voltage boosting methods that has been suggested by other members in earlier posts in this forum. It would be a nice test on how that approach works.

General discussion / Re: Big Box of Parts
Nixies!
I'm sure if Arhi didn't opted out and the box reached him with those, he would love those.

Should there be any new rule like the person should build something with the parts he took out and post it in this form by 1-2 weeks or .....

Project development, ideas, and suggestions / Re: Project I need to do
You can simply take out a output from the socket by using a plug to a small casing and install another power outlet there for the AC. The controlling of the switch is pretty easy by RC5 protocol using a small MCU like Attiny__. You simply need a 25Amps automotive relay for switching and a current amplifier for driving the relay by MCU.
For demo of Remote decoding and processing, see http://goo.gl/TYdCp
For the power connections, 1000Watts load of the AC is high but can be handled safely. You just need to isolate the line properly. Use insulating pipes over the wires for additional safety and I guess 4mm wire should be thick enough to handle the load.

[quote author="Sjaak"]Since the distances are not to big shipping time is just one or two working days. That will also keep shippingcost to a minimum.[/quote]
Expect the cases when it will go international. And I still don';t know whom I'll forward the box after it reaches me because I'm the last in the list.

As suggested earlier(?) A L.P.P should be done after getting shipping cost information from each node(!) so that we will end up in such a route where shipping cost will be minimum for all members.

Project development, ideas, and suggestions / Re: Little Wire - "Minimal AVR programmer and more"
Hi ishan,
I didn't thought about the IDC header, but they should fit with either jumper closed or jumper removed. Don't look at the picture with open jumper over the header.
And about the Zener diodes, they are essential but not necessary. I've stripped Ladyada's UsbtinyISP and am running it without diodes and no problem. http://circuitsdiy.com/simplest-usb-avr-programmer

General discussion / Re: ITead Studio issues?
@dext0rb,
I have previously used both itead and seeed. In my case itead shipped a bit lately, 9 days while seeed shipped in 7 days. But YMMV.

Project development, ideas, and suggestions / Re: Dangerous component/part tester
From the posted picture (Look a the unusual characters, and I bet the underscore is flashing) it looks like the LCD was initialized improperly.
I've made my one with the Atmega8 also(PCB credit: MickM). I had used the files from original archive. There's only small bug in capacitor value measurement there, but rest everything is fine. I attached those again.

General discussion / Re: I just bought this, and you what did you buy ?
@Kartik,
There was no customs for the things I received last week from china. 1. SeeedStudio PCB. 2. the above resistor kit.

In my life I only paid for customs once that was for the $4.30 valued MSP430 launchpad. And I had to pay Rs. 483 or almost $10 for the fees.

I wonder why you(Kartik) don't respond to my emails.

Pirate PIC programmer / Re: Another programmer
Which product or project you're referring?
From the last paragraph I assume it's for programming by PIC-ICSP and JTAG.
But which programmer is this.
