I don't claim to be an authority on breadboarding and prototyping, but I've found a pretty useful way to make my breadboard organized and convenient for quick setup and testing of some basic projects. Feel free to comment if you have any suggestions!

A couple of the design goals were -- use parts that I have on hand, eliminate clutter, and make a more stabile testing platform. It's annoying trying to use buttons and switches that are free-floating connected to my breadboard with wires. I also thought it would be great to keep my test leads with the breadboard, and I noticed that all of my breadboards had adhesive pads on the bottom, so I just grabbed a parts organizer and stuck the breadboard to the lid of the box, then thought, hey, why stop there?

Step 1: Gather Your Parts and Layout Your Kit

Here's an inside view of the kit. You can also see that I insulated the heck out of the connections to prevent shorts,

Use whatever parts you have on hand, or what you feel are the most useful for your projects. Here's the parts that I used:

Breadboard
Small Parts Organizer
2 momentary normally-closed button switches
2 momentary normally-open button switches
1 SPDT toggle switch
1 SPST toggle switch
1 SPDT on/off button switch
2 banana jacks (power)
a bunch of old IC sockets, but you'd be better off with female headers if you have them
wire terminal block (I didn't connect it yet!!)
scrap wire, solder, hot glue, heat shrink tubing

Figure out what you want and where. Drill holes for your switches and other parts and mount them. Grab the number of female headers that are appropriate for each component and drill holes for their wires.
