Use a real Bread-Board for prototyping your circuit

Step 1: History

Picture of History
In the early days of electronic engeneering radio and electronic freaks used real bread boards (litereally cutting boards for bread) to prototype their circuits.

Wikipedia: In the early days of radio, amateurs would nail bare copper wires or terminal strips to a wooden board (often literally a cutting board for bread) and solder electronic components to them.[1] Sometimes a paper schematic diagram was first glued to the board as a guide to placing terminals, then components and wires were installed over their symbols on the schematic. Using thumbtacks or small nails as mounting posts was also common.

You might think this neanderthal technique is obsolete, but there are still a few reasons to use it for example in educational contexts. But first let me show you how to build a circuit on a real bread cutting board.

Step 2: What you need

Picture of What you need
Parts:
  • a kitchen bread board
  • a bunch of thumbtacks
  • some wire
  • an LED
  • a switch
  • a resistor (10k)
  • a 9V batterie
Tools:
  • a soldering iron and solder
  • a marker
  • (optional) a hammer

Step 3: Draw the circuit diagram to the board

The advantage of our breadboard over solderless breadboards is that you can simply build your circuit following the diagram. Draw the circuit diagram to the board.

Step 4: Stick the thumbtacks

Now attach the tumbtacks to the boards. First stick one to every corner. Next stick two thumbtacks to the place where the electronic component will be added.

Step 5: Solder the components

Solder the components to the thumbtacks. You may use a third hand tool for help. Soldering to thumbtacks i a little bit more difficult than soldering to a PCB. It takes more time to heat it up. If you're not sure about your solder joints, use your multimeter to check continuity.

NOW I KNOW WHY THEY CALL IT BREADBOARD!!! THANK YOU!!
same here
I started the same way :D And even today I still use it for high voltage or mechanical uses (like a coilgun).
With "softer" wood it works better (and is not that important).
So cool, awesome idea and history lesson!

I did not know that actual breadboards were initially used to develop circuits. Nice Instructable!
