Adaptive/Assistive 3.5mm Button
Description
## What This Is A Low Cost, Printable At Button. It Interfaces With Any Standard 3.5Mm Mono Jack System, Commonly Found In Support Situations For People Living With Physical Disabilities. At Buttons Are A Way For Someone With A Limited Range Of Motion To Control His Or Her Environment At The Same Level As Anyone Else. These Buttons Can Be Used To Adapt Toys And Home Appliances Such That They Can Be Actuated With Ease. Most At Buttons Available Are Quite Expensive, And Are Engineered To Be Used In Serious -- 100% Reliability -- Situations. As A Result There Are A Lot Of [Diy Projects](Http://Www.Instructables.Com/Id/Cd-Switch/) To Make Buttons Meant For More Relaxed Use Cases. We Wanted To Make A Button That Can Be Used For Toy Adapting And Similar Functions, While Also Providing A Clean And Durable Design. ## Why This Button Was Created As Part Of A Team-Based Senior Design Course. We Worked With A Local Organization, [Ucp And Tasc Of Huntsville](Http://Ucphuntsville.Org/What-We-Do/T-A-S-C/), To Design And Construct An At Keyboard And At Button. ## How Making One Button Takes Me About 8 Hours Of Printing And 1 Hour Of Assembly. ### Materials * [Cherry Mx Switch](Https://Mechanicalkeyboards.Com/Shop/Index.Php?L=Product_List&C=43) * [3.5Mm Mono Port](Http://Smile.Amazon.Com/Toogoo-Chassis-Female-Socket-Connectors/Dp/B00Ezigtyy?Ie=Utf8&Psc=1&Redirect=True&Ref_=Oh_Aui_Search_Detailpage) * 6" Or So Of Wire * Optional: [Compression Spring](Https://Www.Homedepot.Com/P/Everbilt-Spring-Assortment-Kit-84-Pack-13554/203133714) For Adjusting The Button'S Actuation Force. * Optional: [3.5Mm Mono Cable](Http://Www.Mycablemart.Com/Store/Cart.Php?M=Product_List&C=178) To Connect The Button To Things * Optional: Drawer/Shelf/Toolbox Liner **Or** Dual-Lock **Or** Velcro As A Grip Base ### Assembly * Print The Button Base, Button Hatch, And And Key Cap. * Solder The Mx Switch To The Mono Port With Two Pieces Of Wire, About 3 Inches Each. * Install The Mx Switch In The Middle Of The Button Base, And Then Run The Mono Jack To The Port On The Flat Side. Screw The Mono Port'S Threads Into The Hole In The Side Of The Button. * Jam The Key Cap Onto The Cherry Mx Switch. This Can Optionally Be Done With A Light Spring Over The Switch Stem To Adjust The Force Of The Button. * Optionally Glue Or Bolt (M3 Bolts) The Shelf Liner To The Bottom Of The Button To Make A No-Slip Base! Can Also Optionally Have Superglue To Hold Things Together. ## Doing Things With At Button Here I'M Just Running Through Some Small Use Cases That I'Ve Personally Found For This Button. ### Control A Computer Via An Arduino You Can Use A [Small Firmware](Https://Github.Com/Ctag/Cpe495/Tree/Master/Button_Test/Button_Test) On An Arduino Along With A [Shell Script](Https://Github.Com/Ctag/Cpe495/Tree/Master/Button_Test/Button_Test) To Automate Tasks On Your Computer. In The Example Code The Shell Script Uses Xdotool To Generate A Right Arrow Key Press, Which Allows Me To Use The Button To Advance Slides In A Power Point. ### Control A Computer Via Microphone Input You Can Also Wire The Button Directly To A Computer'S Microphone And Detect Button Presses. This Is Still Something We'Re Looking Into, And Hope To Return With More Robust Code.
