digi - key
mouser
unless it is an amazing offer

never post anything from eBay seeing as it could be token down faster due to bidding or selling out

While an oscilloscope is an indespensible tool to have around the lab, I would recommend a decent DMM, power supply, and soldering iron. First, spend about $100, and buy a decent, Chinese clone soldering station (http://www.ebay.com/itm/MD-936-Lead-Free-ESD-Soldering-Station-907-Soldering-Handle-digital-control-/221377168688?pt=LH_DefaultDomain_0&hash=item338b1b8530), a Uni-T UT136 multimeter for $17 (http://www.ebay.com/itm/UNI-T-UT136B-Auto-Range-Digital-Multimeter-AC-DC-Frequency-Resistance-Tester-gi-/281264237873?pt=LH_DefaultDomain_0&hash=item417ca7ad31), and a cheap arse power supply (http://www.ebay.com/itm/15V-1A-Precision-Variable-DC-Power-Supply-Clip-Cable-Digital-Adjustable-Lab-Grad-/390681828322?pt=LH_DefaultDomain_0&hash=item5af6739be2).

These will help you get started, and also sign up for an account at TI for some free samples, but PLEASE do not abuse the privilege of free samples. Only take what you need and SPARINGLY! After this, save up for some more time for $200, and go get a good quality, analog Tektronix oscilloscope that will last you many, many years.
I'm not saying we should kill all stupid people. I'm just saying that we should remove all product safety labels and let natural selection do its work.

TaydaElectronics.com had some great stuff, at great prices and everything I have received so far has been real. They ship from Thailand but I'm general it takes about a week.

Oh tell me about it. 90% don't know what a resistor is.

more like 98% including teachers. i am literally making a 555 circuit and putting hot glue all over it making plexiglass cubes gluing THAT all together putting a battery in ( i mean it is kinda cool i have it so it fits 10 led and they all fit pretty tight and you can put new ones in) and selling it for 10$ its shit this education system ( not yelling at teachers you do your job terrific). off topic we should make a new link if we wanna talk about it

lets go back on topic what should every beginner get ( put thousand of links like this guys)


breadboard :  www.breadboard.com

 i did not know that it was real but it is pretty tight you should check the site out guys

That reminds me of a project I did at school in year 9 (9th grade) we made a 555timer based led thing for timing tooth brushing. They didn't explain to us how it works they just gave us components and tell us where to solder them in, everyone else was buisy making little solder balls, I was the only one who could actually solder properly because I had a soldering iron at home.

Hi,

I'm new here so if I'm not supposed to do this, sorry!

I have a Heathkit IO-18, which is a 1968 vacuum tube oscilloscope, 5 mHz bandwidth, non -triggered. It's not something you'd want to make measurements with, but with playing around and just getting a start on electronics, it'd be ok. It's a single channel, un-triggered.

I've fully restored it, replaced all the caps and checked all tubes. It is safe to use and is clean. I have around $50 in parts, plus about 10 hours of work into this thing.

I also have a hp 54200 digital oscilloscope, 50 mHz. I'm not sure if this works. It's missing the cover but is clean. I tested the CRT, the most expensive part, with a Sencore CRT tester and it test good. When working, it's a duel channel. I have to warn you, it might be a challenge to fix this, or it might be stupidly simple.

If you have no other options, these might be ok. How about $40 plus shipping for the Heathkit and $25 plus shipping for the hp? I live in Connecticut, 06033.
