| Great things come from TI. More analog, of course. DSPs, some logic, battery management. You can sample anything off their [[https://www-a.ti.com/apps/samp/pids.asp|big list]]. 5 different parts per order, with 1 each of the expensive stuff (like DSPs) and up to 3 each of the more common chips (as of 2013). | Great things come from TI.

| The de-facto standard for annoying microcontroller design. Regardless, it's up there with the 8051 and AVR in popularity. It seems like you can get their more popular <$5 microcontrollers sampled. Also, of course, are their little eeprom memory chips, mid-freq RF chips and 'analog glue.' According to their [[http://sample.microchip.com/FAQ.aspx|FAQ]] (link is dead), you can get 3 of 4 different parts, twice a month, shipped via 3-day. | The de-facto standard for annoying microcontroller design.

| - | Lumex has LEDs, high power LEDs, LCDs, backlights, light pipes, and other such. Just look at their various products, and if you can get a sample, there will be a little shopping cart. I know they have high power LEDs, light pipes, and backlights available for sampling. I'm not sure on the specifics of what you can get, and I haven't tried to order anything yet. From their Product Sample Cart page: | ||

| - | >>It is our practice to offer samples from available stock to our customers' technical staff for new designs or substitution evaluation and qualification. Products in sample quantities for any other purpose can be purchased via our distributors. Actual shipment and quantity of samples is subject to availability and unit price. We reserve the right to decline any sample request that in our opinion does not comply with our standard practice. | ||
| - | |||
| - | >I've been trying to get anything from them for a long time; definitely DON'T sample expensive parts (even if they DO have sample option), DON'T use student/hobby emails, and be prepared for LONG waits and MANY requests before anything happens. I've sent three or four requests throughout last 4 months, and only gotten a single reply (after almost a month), stating that the parts are too expensive to actually sample them, despite the option on the page. No response to my follow-up email at all. (August 2013) - vaxquis | ||

Sampled numerous passives (resistor networks, precision resistors etc) from them later on, almost all were sent in separate packages and sometimes they sent reduced amounts or different parts - but overall I got everything I requested without much trouble.
