ARM9 soldering problem is solved.. i made the hot air pencil. See pics and details are ... Parts needed : 1 cheap soldering pipe shaped ,coil heater type:140/- like this http://www.hvwtech.com/products/206/44100_PV.jpg 1acqurium pump + air pipe :130/- 6 inch pneumatic tubing :30/- like this http://ecx.images-amazon.com/images/...500_AA280_.jpg (my innovation it withstands approx 100deg, at the coupling end the temp does not go v high). Super glue , paper etc.. How to : 1.rip apart soldering iron, remove metal tip. 2.Leaving the front hole (where metal tip was there) cover the other holes with 2 layer of paper put duct tape to make the paper hold.This is to prevent air leak. 3. connect air pipe to the 6" pneumatic tubing seal the joint with superglue,put the other end of the tubing to soldering iron metal pipe. with paper as insulator. 4. Close the soldering handle with pipe and wires mine is taped to hold together."Be careful not to short mains wires".My iron had fully i...

See the power IC how small it is , I will have to make a HOT AIR PENCIL. There are 20+ web sites detailing it but I will use my way to do that.. Done the shopping by now. I will create a post on the same soon.

I am asking free samples from a company , for atleast the power section some one named Srikanth G. from their local office ,locking the samples and asking business details again and again . Samples save good $$$. If not i have 10 other alternatives. Letz see what comes out . Board is in progress , 90% of components supply i sorted out. The At01 series has inbuilt loader that will init the chip and peripherials. Now i need to learn the 1st time flashing of the Uboot loader. SD RAM I got : see it on the board before soldering Update: sample will be most probably be released , as i convinced them . Local center guy i forced putting mail to HO. hahaha :). One problem is there: The SDRAM pads are too small ,go under the chip legs.manual soldering will be tricky. UPDATE: IC Pack and samples have arrived , flash,eeprom,power sections things came . from usa, mainchip and ethernet chip has to come from Taiwan and Hong Kong. Look at the Flash IC box , well packed in antistatic box ...

This is phase 1: I am at my office where i work as consultant ..whoa !today passive components have arrived.Means the resistor and capacitors 0402size. The size presented a hurdle, 0603 components are pretty easy to get . But finally i got hold of the components. more are there in my tray shelf . I got passive s for 10 boards for trial build we will take chips 1 pc each . Let the prototype be ready as well toolset .. then may go bulk. phases of build : Phase 1: Passives arrives + jacks etc {done} Phase 2: Active cmp arrives mainly At91rm9200 Phase 3: Solder and test

Why to learn ARM ? ARM is the most popular of leading cores of the embedded processors. it is designed for the specific clients and for different product demands the processor is added with extra feature. there is always high demand of skilled manpower who has worked with arm processor and embedded linux . I recommend few books here you can get as ebooks ,but getting a printed copy is better and you will get a faster /regular learning from it ..may need to refer the books in later part of your career. All big giants like sony ,honeywell,philips,nokia,siemens ,HP work on these ARM core based products. 1) ARM System-on-Chip Architecture (2nd Edition) Desc:The future of the computer and communications industries is converging on mobile information appliances - phones, PDAs, laptops and other devices. The ARM is at the heart of this trend, leading the way in system-on-chip (SoC) development and becoming the processor core of choice for many embedded applications. System-on-chip techn...
