Hi, i'm in a bind. I need to buy a few chips, but they are only 1.30 apiece. The site i'm ordering from requires minimum orders of 35 dollars. I'm looking for parts that would commonly be found in peoples shops that are parts that come in handy often. Things that without it you'd be in a bind. I'm looking for any small electronics, part numbers would be handy. Thinks like Encoders/Decoders, whatever somebody thinks somebody just starting out would need. What are your recommendations? Thanks!

If I understand your post correctly you want misc parts numbers so you can order 35 dollars worth of stuff?? If that's correct can I ask why not just use someplace that does not require that high of a minimum order?
Jameco, Digi-Key even parallax has discreet componets.

I've looked at a few sites, and this site has this part cheapest. I figured i'd order a few of them, and then just throw some other stuff together to make up 35 dollars.

Go to mouser. You can order 5 dollars of parts and have them ship it priority mail for 5 dollars.

If you really want to buy parts to stock your workbench here is a list of some commonly used components. Any others would depend on what projects you had in mind.

Resistors- Qty 10 to 100 ea - 240, 470, 1K, 10K 1/8 Watt or 1/4 Watt.

Capacitors Qty 10 to 100 ea - 0.01uF, 0.1uF, 33uF, 1000uF 25V rating should be enough, 16V may be ok.

Transistors Qty 10 to 20 ea - 2n3904/2n3906

LED's Qty 10 to 20 ea - Various colors to use as required.

Diodes Qty 10 to 20 100V or higher, 1A or more.

Voltage regulators Qty 5 to 10 ea - 3.3V, 5V, +-12V if doing analog/op amp related projects.

These are pretty common parts that are useful in most projects. The resistors and capacitors in particular are used in almost every project you will build.

I'll second kwinn's post as an excellent list!

If you still need to make up a few bucks, hookup wire is always useful, as well are SD sockets.
Male & female pin connectors are also very useful to have as well.

What's is a good source , part # for an SD socket to use with the propeller proto board

Sparkfun has one that looks like it would work. I've used this (http://www.warrantyvoid.us/tiki-index.php?page=Interfacing+SD+media) socket with success several times
on the Protoboard. Of course there is a plug-and-play solution from ucontroller.com (http://www.ucontroller.com) too.

Thanks for all the recommendations. When i first started i picked up a grabbag of resisters, and got some capacitors and stuff. Not sure what the transisters and stuff are used for, i got one of those with a parts bag from parallax that had random stuff in it. I was thinking more along the lines of digital logic that might be useful for whatever reason. Stuff i can't just get at any radio shack. The problem i had the other day was i was doing a presentation on my robot, had some sharp infrared sensors and didn't realize i needed A/D Converters to use them. sadly there was nowhere locally i could get them. I'm ordering at least 4, 8 input a/d's, and i'm wondering if things like encoders/decoders, bcd converters, etc are things it would be useful to have, and if so, what are some part numbers of good ones compatible with the prop. Thanks again for all the suggestions.

I've been getting all my digital chips (logic chips etc) from Futurlec. Worldwide shipping for $4 and no minimum order. Also they seem to have pretty much all the products I need but not millions of similar versions of the same thing, so scrolling through their parts list is much less confusing. Re encoders and decoders, are you talking analog or digital? For analog, the 4051 is a handy part. But just scrolling through the 4000 and 74HC series gives a good overview. For instance the 4000 series at Futurlec fits on a couple of pages so it is easy to scroll through. Both 74HC and 4000 can run on 3V and so are compatible with the propeller.

To a great extent the kind of digital logic chips you use depend on the projects you get involved in so recommending parts is more difficult. In general I would suggest stocking a few (3-5) bus buffer/latches ('373/374), bus transceivers ('245), shift registers (serial in parallel out '595) (parallel in serial out '589) and some decoders ('138/139). ADC's and DAC's are useful too for some projects, but usually need to be selected based on specific requirements.

Russ,

I'm just getting back into the hobby and use many sources listed above along with surplus stores. One of my resources is also electronics being thrown out. It quickly builds back up!!!

10K and 20K resistor networks are handy for pullups. I use 10/20 wire ribbon cable, sockets and headers a lot.

Thank you. I'm looking for a broader parts list. Regulators, IC's, etc.
