hi everybody. I bought a kit with a microcontroller and the training board.
Now I am thinking in buying a lot of thing to make a lot of stupid things,jeje.
I mean some transmiter receiver, temperature sensors, light sensors, hall efect sensors, contact sensors, a numeric board, resistors, capacitors, oscilators, usefull chips,the welder, some fan to remove the smoke, Magnifying glass, third hand,...

But where to buy? Should I buy everything in the same place?(I will buy online)
Could Farnell be good?. When I say good i mean, good value for my money.

thanks in advance.

If you are in a hurry, otherwise they are usually the most expensive but have stuff in stock. Digikey may be ok pricewise, I have only bought from them a few times. I usually try and buy from wholesalers....don't really know where ERMUA is.. :? you must have some wholesalers there.

Gee, you already have the list. Just do a little "Letting your fingers do the walking" on the Internet and find places that have what your want for the least amount of money.

You'll find that, what you think you want today, tomorrow, that thing will not suite your wants. Over time, You'll always want something bigger and/or better. That's how the electronics/embedded controller hobby works and, it's also what keeps us growing in knowledge and experience.

so you suggest me to not buy online, or to not buy to a big companies?
I found amidata and micropic.
Can somebody tell me where did you bought your stuff?

Sure! But on-line... It is the most convenient way to purchase your electronics needs.

As I live in the United States, I buy from Digi-Key, Jameco, Mouser, Newark, Carlton Bates, and the like.

But, Digi-Key is by far my first choice.

I bought about 20 pounds of parts and would hate to think what Digikey would have charged:

Greetings Osaka!
Not sure what electronic surplus stores you have in Africa. But if you have electronic surplus stores they are a great source.
I bought an excellent book from Smiley a member here – Joe’s books can be ordered with many parts and or a butterfly. http://www.smileymicros.com Very cool!

Best of Luck,
John

Yup! I've done those kinds of purchases too, thinking that I was getting a great deal. The fact is, those parts mostly set in the parts drawers as, there never seemed to be the part that I needed in the bunch.

So, now I just design the project using the parts that I want to use and order them specifically for that project.

Does it cost more? Yup! Do I care? If I spend $30.00 dollars on a bag of parts, and I can only use one or two (or even a small percentage) of those parts over the next year or two, then it cost me $30.00 or $15.00 for that one or two parts.

I might as well have just purchased the exact parts needed for that project in the first place.

In fact, I go the the Dayton Ham-fest every year - Usually because I'm looking for good deals on "High Carbon " Steel PCB drill bits. I usually bring home a bag or two of electronics parts that I thought was a great deal. Guess what? Those bags of parts usually sit on the floor in the corner of my play room until I either file them under 'T ' or, I give them away.

In the end, I can't see how that is a good deal!

Edit:
Though, I can totally relate to wanting cheap parts if all you are doing is experimenting and just learning about electronics - but not for designing something that might be going into a critical application, even if that project is a one-of-a-kind.

It would help us geographically challenged engineers fi you would write 'Ermua, Spain' instead of 'ermua' in your profile.

If you want to 'fool around' with parts with circuits where the precise values are not important and the main goal is to get a feel, then such parts collections are fine.

Unfortunately, if you build a 'real' project, you'll have to buy the precise parts. I usually buy a bit more than I need, especially for generic parts, to go into my stock. In the long run you'll want at least all the resistor values of the E12 series and a series of capacitors, general purpose transistors and diodes.

EDIT: There's a lot of stuff available on Ebay. I suspect prices aren't that great except maybe some of the Chinese sellers. Occasionally you can get lots and assortments, but as Carl suggests they may just end up taking space under the bench.

just think my room is empty. I dont have nothing, just the training kit.
I want to have a good stuff no matter if i have to spend 300$ or more. The only thing that i dont want is to feel that I could buy better if i asked before.

I want to buy all kind of sensors,accelerometers, temperature light contact hall efect sensor, relays, also some RF and IR trasmiter reciever,microphone, piezoelectric, some oscilators to develop accurate clocks, buzzers,some engines, some servos generic parts as resistors, capacitors, leds, transistors, usefull ICs, memories, a welder, solder, something to extract the smoke, magnifyer glass,third hand...

As I told you I would like to have almost every kind of eyes for my microcontroller. I usually stay at home few time so I would like to have a lot of good stuff. In fact i am ordering now because I am going back home in 3 weeks, so i will like to find my house full of sensors and good stuff to have fun and try extrange things before a go again some extrange country for long time.

I have been comparing the same welder in micropic and in ariston. In micropic is almost the double.

just now i am thinking about buying a new training kit, no matter if it means i waste my 150$ of my previous training kit. It is so discasting to fall in a problem and not to find nobody with the same trainer than you to help you.
I want something that will work that people have to find support in this forum. With my another training kit i felt alone, and nobody could help me.
Can somebody tell me if this can be a good idea or maybe i should continue fighting with my previous trainer?

The trainer kit i would buy MUST be to develop software in C with some examples to follow. Also I need that the studio software works correctly, not like in the previous, It would help me a lot to find my own way. I can spend...150$ no matter. I want thatever can be a fast tool to learn fast and right.
thankyou.

The STK500 is an excellent development board. And well worth the $80.00 U.S. It is probably the most popular development system used on this forum.

It meets all of the requirements that you state in your Oct 10, 2007 - 7:33 PM post.

The STK500 is a classic. It works well and provides good value. One big bonus is that everybody here knows it and can help if you have a problem with it.

There is no newer product replacing it. The Dragon is more a complement than a replacement.

osaka, try a european store.
Olimex and Propox have many low priced development kits, and you have only to pay for delivery cost (you can use post to keep cost low) and not additional duties, etc, etc etc....
(some months ago I bought something from digikey, about $150 and I paid about 250$ for duties, various taxes, brokerage fees, etc....)

PS: I live in Greece...

PS2: Read carefully the terms and conditions of delivery from digikey site:

"VAT of XX%, along with any applicable duties and brokerage fees, will be due at time of delivery"

I agree whit this. Switzerland is not that bad with taxes and fees, but is adds significant cost. One specific thing to note: Usually you pay your tax (VAT) on the entire amount of the bill, including shipping, not just the products. As shipping from the US can be significant, you'll pay double...

I found that reichelt.de has some of the best prices on the continent. The site is in German, though.

i found it cheap in the german web just markus said. now the last question before buying my second kit in half year...jurjurjur.

Is the stk-500 a training board designed in english and selt in a lot of contries "in english"?
if so i will not have problems... I need english, not german,french or chinese. :-))))

say what what i want to listen.

i want a new kit
waiting every day in my room
ready to do everything that i want
and going always farther than the last time.....¿¿?¿?¿

I just had a look at the site and found the following remark:

Quote:
Gesamte Dokumentation und Software in engl. Sprache

Translated: All documentation and software in English

I think you are all set, then. One more thing. The minimum order is 160€ for a 'foreign' country. I suppose foreign is everything not in Germany...

I don't know what the rules are for taxes in Europe. For Switzerland the Reichelt will deduce the VAT (16%) on the bill/invoice, but Swiss customs will add a custome fee and the Swiss VAT (7.6%).

I just found an old 2004 invoice:

Total Products:    134.97 EUR
Shipping fees:      38.50
Insurance:           1.07
VAT (16%):           0.00
Total:             174.54

When I got the package (payment upon reception) the amounts were:
Amount:            272.65 CHF
Postal fees:        25.00
Customs:            22.35
Total:             320.00

ouch , just now i realiced that i need to buy a power supply also...
do i need to buy some chips or cristals...?
another question, do the people q has stk-500 use it as a development board today?
In how much time can it become obsolet?

Yes, you'll need a power supply. This is something you'll need anyway, not just for the STK500. On the Reichelt page with the STK500 they did advertise a power-supply, I didn't look at the specs, though.

The STK500 comes with a 8515. The 8515 is not very recent, but with 40 pins it has lots of I/O. You'll need more chips, but this depends on your needs:
- Tiny's are cheap and small, for the small and simple project when you don't need many pin's (ATTiny45, ATTiny26)
- Mega's have plenty of resources. Projects requiring a Mega are usually complex enough the you'll have to order specific stuff anyway. Having them in stock is less important.
- If you want to do simple breadboard stuff, stick with the DIL housing for easy soldering. All high density housings usually need a PCB.
- Choose the variable-voltage versions instead of the high-speed version. Most of the time it is more important that is works from 2.5-5.5V than the maximum speed.

The STK500 will get out of fashion, but not today and tomorrow. It will take years for Atmel to come out with a replacement and all the helpful people on Freaks to buy it, and get familiar with it.

If you order from Reichelt, you'll need to order for 150Eu anyway, so there is some room for toys.

If memory serves me correctly the last STK500 I bought (spring of 2007) came with a mega8515 and a mega16. Quite nice!

edit: Guess I should mention that I bought the STK500 from Digi-Key. I don't think that would make a difference in what came with the STK500.

You dont need to buy a sample from every AVR microcontroller.
3-4 chips are OK for development purposes.

My favorites are:
Tiny26 : Small, with ADC
Tiny2313 : Small with UART but no ADC
Mega8 : A beast in a small case.
Mega16/32 : A typical megaAVR
Mega128 : For big jobs

The price differences from small tiny's to Mega8 are very small (up to 2 euro cost), and have no meaning for development purposes.Stick with Mega8 and Mega16/32 in the begining.....

Yup the mega8 is a good example, all the peripherals are there, 8k is enough to start, but it is still in a reasonably small package (narrow DIL).

Now that i have free time I am trying to make a list of the things that I want to buy(everything)
I decided to order in digikey because they have the stk500, so I only pay one shipping, but... I already started to realise that is SOOOO EXPENSIVE. And I am not talking about 10%.
I am comparing the prices with analog, is much chipper that this. So, I am thinking that i will buy ONLY the stk500 to the digikey, and the other things to other company as analog. BUT, analog doesn't have capacitors, resistors, cable, and this kind of little things that i need.
IS NO ANY SPANISH PEOPLE HERE...
I feel that Spain is still in the age of the bull-figthing. I want to go to the supermarket and buy bread and some accelerometer. When will it happen?...hehe.
So this is the problem, and as I want to buy giroscopes and accelerometers and aaaaaaaaall kind of stuff which I could need someday to do something digikey is stealing me a BIG money for this so it is worthy to pay 2 shipments. I want to buy a lot of thing in one time because I dont have time to buy and buy again and wait and....no, I am only few days in Spain so i would like to enjoy at maximum.
The chistmas are arriving and i would like to find my family and my micros when i back to spain. But i should hurry up.
If somebody could help me I would really apreciate it.

Welcome, Osaka. I looked for Ermua on the google map... looks beautiful from the map! I notice that Europeans all use the BigEndian style for locations and dates, with the Big Place first and the Big Date first year/month/day. For some reason, Americans always put the places and dates in the Intel LittleEndian style... city, then state or country, day/month/year instead of the other way. Some countries even drive on different sides of the road! I find this funny, because the guy that started Intel was from Hungary, and the guy that designed the 8080 and the Z80 was also not born in the US (Help me Cliff! I got it... Frederico Fagin... mind like steel trap). I admit, I think it is completely logical to parse from large to small.

We were looking for Texas Instruments REF200AU's (at work). It seems no one in the entire world had any stock EXCEPT a distributor in Spain (and TI was quoting approx. 26 weeks lead time).
