Altoids Tin Portable Breadboard with Power Supply

Im using solderless breadboard very often, I find it very useful you dont have to solder everything, so you will not destroy your parts and you can quickly change something if theres a problem. Recently I am working on one big project which contains few small projects first was the Altoids Tin Helping hands with fume extractor and heres the second project.



PARTS : 
1x LM317
1x 120R rezistor
1x 760R rezistor
1x 330R rezistor
(or you can use you own values which you can calculate from the equation on the picture in the second step)
2x Switch
Some DC connector (depend on what supply you want to use, ive also used 9V battery to make it really protable)
Altoids Tin
Small solderless breadboard
optional = control LED
piece of protoboard to solder on

TOOLS : 
Soldering iron
dremel (im using some fake chineese)
...

Step 1: Circuit

heres the circuit of the regulator ive putted it on piece of protoboard
while assembling keep on mind that you have to put it inside tin, so dont make it too big 
then make leads from output and ground to the two rows on the breadboard (ive glued them)

This is an awesome project. Do you know exactly what the type or model number of that breadboard is? Its a perfect fit and I would like to find one just like it.

Hey there, I just want to say what a great project you built! I just have one question, instead of having the output be in a breadboard could I put a ground, 9v, and 5v terminals on the case instead? Im sort of new to this and im also wondering what kind of things you would run on the breadboard.
Any help will be greatly appreaciated!
Thanks.

Hi and thanks :)
Of course you can do that. You dont have to connect 9V and 5V to the breadboard you can instead connect it to some connector

[crf250rider14]

Alright cool. But could you maybe take a few photos of the circuit that is inside the tin. Or maybe a little better explanation.
Thanks again.

Well as you can see circuit is made at prefboard and I understand that is hard to see connections but what specificly you dont understand ?

[crf250rider14]

Like what goes where, how the wires and pieces are placed onto the board. I understand everything else about the project just do not understand how it is layed out.
Thanks again for the reply.
Oh and one more thing, I see you have a power adapter input on the side of the tin, what kind of adapter would I use? Like a wall wart?

[legwinskij]

Well I've used perfboard with paralelly connected pins (http://farm4.static.flickr.com/3262/2556867092_7e890a61a9.jpg right one)
one line is for + one for - and one for adjust. Yes you can use any wall wart you want up to 35V but then theres problem with overheating LM317

[crf250rider14]

Hmm ok sounds good. One more question, could I use http://www.radioshack.com/product/index.jsp?productId=2102861 for my terminals?
Thanks again.

[legwinskij]

Yes of course you just have to solder two cabels coming out of the altiods tin (black and red) to these terminals

Good packaging.. would be better if u add an led as an indicator any ways gr8 portability..

[legwinskij]

well there is LED as indicator you can see it on the pictures and ive mentioned in the instructable that it is optional but thanks :)
