mozikluv Posted September 22, 2003 Report Posted September 22, 2003 ;D hi there mixos, this is what i have been waiting for, you're right dont easily find the free button sample. thanx, thanx, thanx for this post. more power to this community. :) Quote
xenix Posted October 31, 2003 Report Posted October 31, 2003 yeap the free chip thing works ..got a friend in the states thats mentioned he did it and encouraged me to do the same Quote
billy Posted January 3, 2004 Report Posted January 3, 2004 I have just ordered some free component samples from MAXIM. Thisis amazing :) You get them for free ! How is that possible ?Anyway, I would like to ask if there are any other companies thatdo the same as well.And finally, has any greek fellow ordered from MAXIM with regular (free) shipping ? If yes, how long does it take for the mail to reach home ? Quote

MP Posted January 3, 2004 Report Posted January 3, 2004 How this is possible: The IC companies want "you" the engineer to use their product in a design. If they give you a 25 cent part and you make a good design with it and it becomes a product, they will sell thousands of this part to the manufacturer of the product. This kind of makes you a part of their sales team in a way.I have gotten many microprocessor chips this way. It is better than purchasing several and then deciding which ones are best for your project. Also, many have a link to their newsletter and they will inform you if there is a new part. You can get a sample of it before it hits the market. Check the "Yes" box for the newsletter from these companies.MP Quote
billy Posted January 3, 2004 Report Posted January 3, 2004 Yes, you are totally right ! I just ordered my first microprocessor frommicrochip in order to play around with it :)Any recommendations of other good and popular samples to getfrom various companies ? I am quite new with thirst to learn newthings, please help :) :) :) Thanks 8) Quote
MP Posted January 3, 2004 Report Posted January 3, 2004 Billy, Mixos might be a better source for the Microchip devices (PIC). I have not used them for quite some time now. I primarily use the Atmel AVR series and ATMEGA series. In my case, I have a local distributor, which takes my sample order and ships them to me, usually 2 each.MP Quote
mixos Posted January 4, 2004 Author Report Posted January 4, 2004 Can anyone suggest any interesting chips that availaible as samples?

billy Posted January 4, 2004 Report Posted January 4, 2004 Texas, national and microchip worked fine, I am waiting for myfree samples. Texas offers free courier shipping too ! unbelievable !Nevertheless, the fairchild company doesn't work because youcannot register in order to get the samples.I wonder if I can make more than one orders to the same address...

Guest Kasamiko Posted January 26, 2004 Report Posted January 26, 2004 ;D just ordered 30 pcs of chips from TI..and I received it within 5 working days via UPS..and yet I request another 80 pcs.! of their products and they shipped them all promtly!! ;D ;D.In fact I just received a call from UPS telling me that my package has just arrived!!

billy Posted January 26, 2004 Report Posted January 26, 2004 Hello all ! This is the crash test of the major semiconductor companies regarding their free sample service. The test trial was carried out during January and the results are the following (recipient in Greece) :GOLD MEDAL : Texas Instruments ;DOrdered : 3/1/04Delivered : 7/1/04Time taken : 3 business days (!!!)Delivered via : UPSPackage : Excellent (large paper box, ICs packaged in their original plastic tubes and each tube was put inside an antistatic bag. All antistatic bags were protected with lots of extra paper).SILVER MEDAL : Maxim - Dallas Semiconductors :DOrdered : 3/1/04Delivered : 12/1/04Time taken : 6 business daysDelivered via : Regular post (not registered)Package : Poor (plain envelope with no bubbles, ICs in plastic antistatic cases, but one of two broke in delivery).BRONZE MEDAL : Microchip :)Ordered : 6/1/04Delivered : 19/1/04Time taken : 9 business daysDelivered via : Registered postPackage : Excellent (ICs in plastic antistatic cases, cases wrapped in bubbles and put inside paper boxes).DID NOT QUALIFY1) National Semiconductor : A great disappointment, I ordered some items on 3/1/04 and they are still 'in process' !!!!! :-\2) Fairchild : Does not send samples to Greece !!!!! >:( Quote

billy Posted February 25, 2004 Report Posted February 25, 2004 You won't believe this story... :oAs I have written before, I have ordered samples from some companies in order to find the best one, which is of course TI (best record : TWO days from Order to Delivery, from US to Greece). :oBut today I received something which I never ordered (and still don't know if I CAN order at all) : a five kilo box full with data books, FREE of charge, right into my door ! :o :o :oI know you won't believe me, so I attach a photo with all the stuff laid on to my floor ! ;)So, please pick the right answer to the question "why ?"a. This was all a delivery mistake and I am just the lucky guy.b. A hacker log into my account, ordered all this and paid for it !c. TI has a LOT of money to give around and they just don't care !d. They have read my past thread about the qualifications and they decided to give me a gift.For your information, a local electronics store sells ONE of those data books for over 30 euros and even more !WOW ! :o Quote
Guest Kasamiko Posted February 26, 2004 Report Posted February 26, 2004 8) A very LUCKY GUY!!! :o :o :oI'm waiting for it too!! ;D ;D Quote
MP Posted March 10, 2004 Report Posted March 10, 2004 I have noticed lately that all my free samples from Maxim have been very small surface mount rather than pdip. Anyone else getting this? Sure makes for hard prototyping.MP Quote
billy Posted March 10, 2004 Report Posted March 10, 2004 In the request form of Maxim you have to specify the desired package type, instead of the 'no pref' option !Of course the requested samples must exist in PDIP package, some of them are SMD only. Quote
MP Posted March 10, 2004 Report Posted March 10, 2004 Yes, I know this. But the ones I have been requesting lately are not available in this package as samples. It looks as if I am going to spend a little time making adapter boards. ::)MP Quote
MP Posted March 14, 2004 Report Posted March 14, 2004 I think that I should add:I am very grateful to these companies for providing samples for my prototyping purposes. We might rate them as fast or slow or grumble about package types available, but the bottom line is, they are free and an expense I do not have to provide to find out something is not what I want. I did not want my previous post(s) to seem like I was not appreciative of this service from them.MP Quote

Guest Kasamiko Posted March 17, 2004 Report Posted March 17, 2004 @ ZomBiEWhat's the pacticular number of chip you request.. :o Quote
ldicdican Posted March 17, 2004 Report Posted March 17, 2004 Analog Devices: i've just build a 2x120W amplifier ONLY by usingFREE SAMPLES!!! ;Dhello mate!can i have a copy of the schematics you use on building that 120W amplifier?i would also just like to build one for myself....thanks ! Quote
