Free Sample Chips!

All of the contents contained in this post is by mixos of Electronics lab, none of the contents is mine, nor have I edited it.

Hi,
I found this on another forum. Its about free sample chips you can order from companies such as Texas Instruments (TI) so you can make projects or just mess around with.>>>

If you don�t know it, read below how to obtain free chips.
Many semiconductor companies offer free sample chips or other electronics products that they produce and send them to your home for free (without even post fees). This is a marketing technique. When someone orders some sample chips from them and designs his circuit with it, then in the commercial product they will use their chip again. Having this in mind they know that at the end they are well-off. Bellow is a list of companies that send free samples chips with online order:

The first four semiconductor companies are the best in sending chip samples.
If you know more companies that offers samples post their site.
Tips:
:smile: When you visit a company�s site usually you don�t find the samples order page very easily.
:wink: You must search and navigate thought their products and find a �samples order� button.
Always put your name, address etc clearly
Not all products can be ordered as samples
Every company has its own web design (some are more complex than other) so don�t give up with the first look. Make a good navigation.

Of all of those companies listed, TI is probably the best and most reliable. You can usually get your samples within 2 business days!
I have only tried a few of the listed companies.

Remember on some sites, you have to "hunt" around for the samples section.

Hey, anyone know what kind of amplifier and comparator I should get in order to build a motion sensor. Also on the schematic, what is PIR?

Hi Ranger, PIR = Passive Infrared. That kind of motion sensor just uses the ambient IR energy in the environment, and looks for changes in the IR imagery. The more complex ones would use an IR camera, and watch for movement in the 2-D IR image. The simpler ones like those used in security systems use a segmented IR lens to focus multiple images onto a single IR sensor. As the IR image changes from motion, the multiple images that are focused on the IR sensor move, and this usually results in a change in the amplitude of the output of the IR sensor. The detector circuitry looks for changes in output voltage greater than some allowed amount per unit time. If you move around slowly enough, you can walk past most PIR sensors. But from my experiments, you have to move reeeeeaallllly slowly!

We had a thread about motion sensors a while back here:

https://www.physicsforums.com/showthread.php?t=87267

Did the links in that thread help out?

Okay thanks for the input. I've decided to go with an Active IR motion Dector.

http://www.ee.washington.edu/conselec/Sp96/projects/mitchrob/proposal/figure3a.gif [Broken] has a detector and a receiver circuit. As I understand, the beam that is transmitted by an infrared diode is received by an infrared transistor which sets off the alarm. So these are two different circuits that need to be made separately. Isnt there a way of combining the transmitter and receiver into one circuit? If not, do they have to be placed close to each other or something?

1. What types of free samples are offered by TI, Maxim, and other companies?

TI, Maxim, and other companies offer free samples of their semiconductor chips. These can include microcontrollers, sensors, amplifiers, and other electronic components.

2. How can I request free samples from these companies?

To request free samples, you can visit the company's website and fill out a sample request form. You will need to provide your name, contact information, and details about the specific chip you are interested in.

3. Are there any restrictions on who can request free samples?

Yes, most companies only offer free samples to engineers, designers, and other professionals who are involved in the design and development of electronic products. You may also need to provide proof of your company or project to be eligible for free samples.

4. How many free samples can I request?

The number of free samples you can request may vary depending on the company's policies and the availability of the specific chip. Some companies may limit the number of free samples per person or per project.

5. How long does it take to receive free samples?

The time it takes to receive free samples can vary depending on the company's location and shipping method. In general, it can take anywhere from a few days to a few weeks to receive your free samples. You may also need to pay for shipping costs.
