I get a vicarious thrill from watching young Makers’ eyes light up as brightly as the LEDs in the conductive dough they are working with. But that feeling is too often followed by a sense of shared frustration at the increased difficulty when they switch to a solderless breadboard.

To ease the transition, I have called back to duty the springboard, a 50-year-old relic that’s difficult to find commercially these days, but is easy and cheap to make. The layout of this model is designed to mimic that of a breadboard for ease in graduating to the next level, making the world of breadboarding a much happier place for all.



Step #1: Design your board

Build a Cheap and Easy No-Solder Prototyping Board
  • Set the springs down (while not under tension) and mark where you want to attach them to the board.
  • The number of springs you use depends on the complexity of the circuits you plan to build. The most basic design has the two 2" springs as vertical rails on the left and right sides, with two columns of the 1/2" springs running horizontally between them with two or three springs in each column. More complicated circuits might require the addition of more rows. For younger makers and beginners, space the springs so that the legs of an LED can easily span two of them (about 3/4" apart). Springs need to be closer together if the circuit calls for smaller components, such as transistors.

Step #2: Screw down the springs

You don’t want any of the springs touching each other, so smaller-headed screws or even finish nails are best for boards with closer spacing. Screw them down with your power drill.

Step #3: Energize

Build a Cheap and Easy No-Solder Prototyping Board
  • The board is powered using a battery with a snap connector or repurposed 5–12 volt wall wart with the tip removed and the wires stripped and tinned. Connect the positive wire to one of the 2" vertical springs by spreading the spring with a pointed object (such as the probe of a multimeter) and inserting the wire. Connect the negative wire to the other vertical spring. Complete the circuit by connecting individual components from spring to spring, using jumper wires when needed.
  • In addition to expressing the connected circuit visually, this setup makes it much easier to practice using a multimeter at various locations. By the time students reach the limitations of the springboard, they’ll be ready to move onto a breadboard and expand their repertoire.


Additional Activities for the Electronics Springboard

In Project Make, electronics instruction begins with guided experimentation using conductive playdough and electronic components found in the Squishy Circuits kit. Students experience fundamental concepts such as polarity, open and closed circuits, series and parallel circuits, short circuits, switches and more using a friendly familiar model.

We then use Charles Pratt’s excellent Make: Electronics which uses on hands-on experiments as the framework for further study. Students learn the basics of multimeter usage, components are introduced as they are needed for specific experiments and a bit of history and theory (even some math!) is sprinkled throughout. The springboard replaces jumper wires with alligator clips in the early Make: Electronics experiments. The small boards pictured for Experiment 3 and 4 are the first projects I made using a springboard and are still in use today.

The history of how this tool made it into our curriculum and how its use has evolved is one that illustrates some of the unique aspects of a having a class centered around maker principles. Over the summer, we received a donation of old electronics parts from a retired teacher that included a number of large boards with 144 springs arranged in a 10 x 12 array. I immediately saw the benefits of these relics and thought of designing a smaller model to be made using our laser cutter. My skills weren’t quite developed enough to allow me to get the job done by the time I planned to begin the lesson, so I hacked up a couple of the big boards, attached them to a piece of scrap wood using epoxy and called it version 1.0.

I have since made several laser cut versions (attached design file created in Inkscape using layers for the different cuts), but have come to appreciate the added value of having students make the simple boards shown in the article. Measuring and laying out the springs, combined with the use of tools ranging from handsaws to chop saws and hammers to portable drills serves as a nice introductory project with skills which transfer to other more complicated projects down the road. At the end of the lesson most are dismantled so that the parts can be used again, I keep the best one or two as examples for future classes.

The most complicated projects that we usually do on a springboard are LED flashing capacitor-transistor circuits like this one from Madlab, after which they move on to modern breadboards for more complicated projects using ICs.

    You get a piece of copper circuit board, it certainly used to be readily available as scrap pieces, then use that as the base. All ground connections are soldered to the board, while the rest ride above it. This provides a stable base for the circuit, yet it’s easy to desolder the pieces. But the connections will be more stable.

    The white breadboards that have become common are now forty years old. But they came in the age of ICs, and re less suited for discrete components, even analog circuits.

    Kids have to learn to solder at some point, the can’t be spoonfed forever.

    That said, the first things that I put together that did work were parts I took out of scrap electronics, and I twisted the leads together. That had the advantage of taking my soldering skills out of the equation.

    Another way of making a prototype circuit with discrete components is to glue your schematic to a pine board. Nail copper plated flashing nail in at each circuit node to a depth of about 1/4″. These are small nails available at hardware stores or home centers.
    Due to the copper plating, the nails solder very well. So you can solder the leads to the top of the nails. This makes an inexpensive prototype that does not need to be disassembled (although re-use is easy). The kids can take the circuit home with them and save it.

    I genuinely do not mean to discourage you (finding novel solutions to teaching electronics is a very laudable goal), and mean this in the nicest possible way, but I feel like this breadboard design is a complicated and low quality solution to a non-existing problem. A quick search on Google shows many sources for quality professionally-made solderless breadboards for only $3-4, in single quantity — about the same as a pack of screws, and definitely less than screws, springs, and laser cut components. Given that a quality solderless breadboard is a foundation of learning electronics and that this solution is likely more expensive and certainly vastly more effortful than spending $4, I’m not sure that I would recommend this for people learning electronics — especially given the mechanical difficulties, and limitations regarding being unable to handle the components required for the very beginning lessons on (for example) 555 timers, logic gates, or op amps.
