MAKE_V28_high
MAKE Volume 28 hits makers’ passion for play head-on with a 28-page special section devoted to Toys and Games, including a toy “pop-pop” steamboat made from a mint tin, an R/C helicopter eye-in-the-sky, and a classic video game console. You’ll also build a gravity-powered catapult, a plush toy that interacts with objects around it, and a machine that blows giant soap bubbles. Play time is a hallmark of more intelligent species — so go have some fun!

 

Coffee Table MAME Console

ERRATA: In Volume 28’s “Coffee Table MAME Console,” the arcade buttons can be OSBF-30 or OSBF-24. Also, quick disconnects are a nice upgrade from spade connectors: 0.187″ for joystick, and 0.110″ for buttons.

 

Pop-Pop Steamboat

By William Abernathy

Build a toy steamer that runs only on heat and the water it’s floating in. (Page 70)

See how MAKE Labs engineering intern Daniel Spangler made a Copper Pipe Alcohol Lamp for the Pop-Pop Steamboat’s heat source, instead of a candle.

 

Gravity Catapult

By William Gurstelle

Get medieval with this portable, stowable, gravity-powered trebuchet. (Page 84)

Gigantic Bubble Generator

By Zvika Markfeld

Arduino-controlled Bubblebot blows enormous, undulating soap bubbles. (Page 94)

Check out the full Gigantic Bubble Generator project build.

Arcade Console Materials

  • Plywood, 1/4”–3/8” thick (7mm–10mm or so), 3’×1’
  • Pushbuttons, arcade style (OBSF) (2)
  • Switch, toggle, with safety cover
  • Joystick, arcade style, 4-way digital (i.e. on/off, rather than variably sensitive)
  • I/O expander chip, 16-bit, MCP23017 Get the MCP23017-E/SP through-hole version rather than a surface-mount package.
  • Connectors, female (aka jacks), RJ45 (Ethernet), with PCB mounting posts (2)
  • Breakout boards, RJ45 (2)
  • Cable, RJ45 (Ethernet), 6’
  • Speaker, 1/4W

Bubble Mixture Materials

Note: Depending on the brands you use, you may need to experiment with quantities for your soap mix to achieve optimal bubble performance.

  • Distilled water, 1 gallon (4 liters)
  • Bubble solution, 1 gallon (3.2–4 liters) from a toyshop or online
  • Dishwashing liquid, 14oz (400ml)
  • Liquid glycerin, 14oz (400ml) available from some drug stores, natural foods stores, or online

Making Your Own Frame

building bubble machine frame

Tools and Materials

  • Clamp or large clip (2)
  • Saw, for wood
  • Screwdriver, to match screws used
  • 1×2 lumber (nominal), 3′ (5)
  • Wood screws (10 or so), 1″
  • Hinge (2), about 1.5″ long
  • Wood screws (12), 1/2″ to attach hinges
  • Wood glue

1. Screw and glue together two 3′-long sticks into an uneven X shape, making the cross at about 3/4 of the length.

2. Now do another pair. Make sure the two Xs come out as identical as possible to one another, for maximum stability. Don’t worry about excess wood. You can trim it off later.

3. Connect the two Xs with a horizontal stick, using both screws and glue.

4. Leave an extra 4-5″ sticking from one side, for the kit box housing the Arduino.

That’s it! Now you’re ready to dress it up (I used pool noodles) and add the giant bubble blowing workings.
