D EC O M P R ES S IO N T H ER A PY The super-loud Boom Stick is a PVC air cannon that delivers m axim um bang fo r the buck.It assaults the startle reflex of any nearby victim ,add ing an instant rush of physicalterrorto haunted houses,art pieces,pranks,and perform ances.

Iw ork in haunted houses during the Hallow een season,as an actor,guide,technician,m akeup artist,and effects creator.

Som e of m y effects instillfearthrough foreshadow ing o r com plex storylines,but the m o steffective w ay to scare

people is often justa sim ple,brute-force startle.

The aircannon is a greatand safe device for such scares.

In its sim plestform ,itconsists ofan air reservoir,a q uick-

exhaustvalve (QEV),and som etim es a resonating cham ber.

H aunted ho use suppliers and special-effects houses sell

com m ercialm odels with Iarge-gauge Q EVS,butthese cost hundreds ofdollars.Hom e projects thatrely on a standard aircom pressortypically use sm aller,cheaperw ater valves from w ashing m achines o r sprinklers,butfor m e,these designs have yielded only a d isappointing ''poof-hiss.''

Inspired by the Pvc -based designs ofspud gun enthusiasts

(butIeaving outthe potato),I've found a betterapproach: a tw o-stage,cham ber-sealing,quick-exhaust,piston-valve aircannon thatyou can build outofcom m on plum bing

BA BY B EAT S T his sim ple seq uencer Iets babies p lay w ith shapes,sounds,and Iig hts,w hile it also teaches o lder kids the basics of electro nic m usic - and secretly you'll have Iots of fun w ith it yourself.

Iw anted to m ake a unique present to give m y daughter fo rherfirst birthday,a m usicaltoy that she could sit dow n and play w ith im m ed iately but that w ould also becom e m ore educationalfor her in a few years.So Ibuilt her the R-Tronic 8-B it,a sim ple m usic seq uencer thatIets you build up,play back,and edit m usicalpatterns.It uses w ooden shapes as buttons and LED S instead offancy displays.

Istarted on the project3 m onths before m y daughter's birthday,program m ing a Picaxe m icrocontro llerw ith a

speakeron a breadboard,using justenough software to m ake the sequencer's 4 no ises.T hen Iadded 4 sw itch inputs to triggerthe sound s,follow ed by 12 LED blinkies.

Ipo rted the tangled breadboard circuit to a neat printed circuit board ,and finally built the w ooden fram e and fit the electro nics.T he finalw iring w as com pleted the night before m y daughter's birthday party.

If Ihad any w orries that she w ould n't Iike the R -Tronic,

Ineedn'thave.As soon as she saw it,she knew justwhat to do.

Sm artstructures range from K2's vibration-dam ping Fourskis to the adaptive m irrors in M auna Kea 's Keck telescopes that counter atm ospheric aberrations.Som eday they m ightalso enable buildings and bridges to counter stresses from traffic, w eather,and earthquakes.H ere's an introduction to this fascinating technology,a desktop ''skyscraper''that uses integrated sensors,actuators,and electronics to canceloutvibrations.

O urskyscraperis a flatalum inum beam ,and forthe sensors and actuators w e'lluse piezoceram ic w afers,w hich co nvert physicalbending into voltage and vice versa.Piezoceram ics are used in stereo speakers,m icrophones,accelerom eters,and m any otherdevices.

A sim ple feedback circuitcloses the Ioop betw een oursensors,w hich detectthe beam 's m otion,and the actuators,w hich give itIittle calibrated pushes.Strike the beam Iike a tuning fork, sw itch the circuiton,and the system counteracts the vibrations and stops the m otion instantly.You can subtractdam ping as w ellas add it:throw the phase sw itch the otherw ay,give the beam a tiny tap,and w atch the vibrations grow to a m axim um .
