Looks good, maybe you want a sensor and/or buttons for the arduino though, otherwise you'll quickly run out of fun things to do.
Will components like ICs and switches fit straight into a breadboard? Like, is the distance between holes standardised?

That depends on the components. Dual In-Line Packages (DIP) will in 99.99% of cases fit in breadboards.

For the most part it is, there are some exceptions with power components and higher current ones usually. However most components are just fine.
Yeah, the spacing on a breadboard is standardised 2.54mm. As for capacitors, you'll want an assortment of electrolytics and maybe a few ceramics. I'd probably recommend ditching the 741 op amps though, they're severely outdated and a bit of a hassle. Try picking up some LM324s or something.
Edit- Since you're picking up some Zeners, you'd be as well picking up some regular signal diodes too. 1N4148 or the like.
Am I missing anything I'll probably need?

Fuck, that cost

Right, I got the wrong type of diode. What a tit.
Yeah, that looks pretty good as a starting kit! Those buttons'll need wire soldered to them to be useful though, they've got lugs as connectors.
[QUOTE=sambooo;44711431]Hey guys, I fancy a go at playing with some electronic doohickies but I don't own anything to play with nor do I want to invest in expensive equipment. I'm looking at getting an Arduino Uno, a breadboard, a bunch of wires and a cheap bunch of LEDs and resistors.
Is that a good starting point?[/QUOTE]
If you want a nice starter project you could buy a PIC and make your own little programmable board with some headers to mess about with, will be cheaper than buying an Arduino and more fun :)
These switches fit in your breadboard: [url]http://www.bitsbox.co.uk/index.php?main_page=product_info&cPath=116_117_119&products_id=864[/url].
You could go cheaper using ebay, however be prepared to wait a few more weeks.

You should get tactile switches aswell, like these:

They're a bit bitch to get into breadboards but usually they will stay in there when you bend the legs right.
Or dx.com, but that only has knock offs, even though that does not matter for stuff like buttons and whatnot.
Argh, bitsbox cleared my shopping cart for seemingly no reason. I'll re-add stuff later. Thanks for your suggestions guys! :)
As for getting stuff a bit cheaper, I'm not patient enough to wait for deliveries from china. (I once paid £10 for next day delivery on a £1.20 cable)

I did see a video of someone doing that so I might try it some day
[QUOTE=sambooo;44712254]I'm not sure whose advice to take here because this field is alien to me. The last electronics work I did was 16 unless you count taking A level Physics.[/QUOTE]
My personal advice is to grab any books on electronics you can find, first. Check your library (just make sure they're newer than 1950's-60's :v: ) or local book-store an read up on it as much as you can first before deciding what direction you want to go with it. Also, find old electronics junk to disassemble.

Unless you want to be poor, get used to purchasing from china.
dx.com is useful to browse because they have a (somewhat) managed inventory but I've generally had much better experiences just purchasing from ebay. On ebay you deal with individual sellers who each usually have massive inventories so finding things when you're not sure what you're looking for is impossible.
Usually I'll find something I want on dx and look on ebay for the same item in different quantities or types, or just for a cheaper price. dx is usually quite restrictive on quantities, only offering some component in 100x quantities when really 10 will do for quite a while.
The shipping time isn't so bad, usually you can stay busy with something in the mean time and usually you're buying something to try it out or to pad out your inventory, not because you need it now.
Also regarding something you said earlier about picking through the large amount of capacitors; for some types of components having a complete inventory is pretty much impossible. As you may have guessed, there are so many types and values of capacitors that it's just impossible to stock everything. My inventory of capacitors has hundreds of different values across different types of capacitors and is nowhere near complete. For starters, bitsbox has [url="http://www.bitsbox.co.uk/index.php?main_page=product_info&cPath=65_286&products_id=1993"]This kit[/url] which might seem pricey but will probably last you quite a while.
Usually a few values of capacitors/resistors are used way more frequently than most of them. For example 10K ohm resistors as pull-ups. In most cases you can also connect capacitors/resistors in sequence or parallel to recreate other values.
I've wanted to make a laser spirograph for a long time now, so today I gave it a shot.
At the moment, I need a new power supply for my 3d printer, so I couldn't go right into making a mound for the motors, lasers or mirrors, but a little bit of hot glue and the surface of my desk seems to do the job as a temporary solution.

I guess you know the leonardo can function as a mouse/keyboard for your computer? I might get one/a mini version for that so I can do some stuff like a control panel for KSP
Richard Feynman is an awesome guy... so sad he died..
Even though his speciality is physics, he does quite a good lecture on Computer Heuristics:

I actually have one of those, it's pretty good especially if you look at the price you're paying. It's kind of hard to expect good build quality at this price now isn't it?
I bought a digital station from Radioshack for $80~, works a treat so far. Just need to get a chisel tip for it, this pencil tip is unwieldy at times.
As for that chinese knock-off, I can expect poor build quality, yes, but fucking second-hand parts?
I was bored and decided to redesign my main speaker's crossovers because they suck. I built them many years ago following a project I found on [URL="http://partsexpress.com"]partsexpress.com. [/URL]

There's something about analog filters that just gets me going. I love bode plots, phase diagrams, s-domain analysis and all that good stuff.

Is it also possible to build LED frequency visualizer this way?
