Kauj Ruam 1: Nws Ua Haujlwm Li Cas?

Txheej txheem cej luam

Lub kaw lus HairIO ua haujlwm tawm ob lub hauv paus ntsiab lus: kov tau thiab tiv taus cua sov. Los ntawm kev hnov qhov kov, peb tuaj yeem ua rau cov plaub hau txuas ntxiv rau qhov kov. Thiab los ntawm kev ua kom sov ntxiv, peb tuaj yeem ua rau hloov xim nrog cov xim thermochromic, thiab hloov pauv nrog cov duab cim xeeb. Ib lub bluetooth nti tso cai rau cov khoom siv xws li xov tooj thiab khoos phis tawj sib txuas lus nrog cov plaub hau ib yam, txawm tias ua rau muaj cov duab lossis xim hloov, lossis kom tau txais lub teeb liab thaum kov cov plaub hau.

Piv Kev Sib Tham thiab Siv

HairIO yog kev tshawb fawb platform, uas txhais tau tias peb yuav nyiam pom koj ua dab tsi nrog nws! Qee qhov kev sib cuam tshuam peb tau tsim tau qhia hauv cov vis dis aus saum toj no, lossis hauv peb cov vis dis aus tiav hauv Youtube.

Ib txoj kab-hloov pauv cov plaub hau tuaj yeem ceeb toom rau tus neeg hnav ntawm cov ntawv xov xwm los ntawm kev maj mam rub tus neeg hnav lub pob ntseg thaum nws txav mus.

Lossis tej zaum nws tuaj yeem muab cov lus qhia rau tus neeg hnav, txav mus rau hauv qhov kev pom kom pom tias yuav tig mus rau qhov twg.

Cov plaub hau tuaj yeem hloov pauv ntau, rau cov style lossis kev ua yeeb yam. Cov style tuaj yeem hloov pauv txhua hnub, lossis hloov kho rau ib qho xwm txheej tshwj xeeb.

Cov plaub hau kuj tuaj yeem ua kom muaj kev sib raug zoo hauv zej zog; xav txog kev braiding tus phooj ywg augmented plaub hau, tom qab ntawd tuaj yeem hloov tus phooj ywg cov plaub hau xim los ntawm kov koj tus kheej braid los ntawm qhov deb.

Cheebtsam

Txhua qhov kev nkag siab, kev xav, thiab kev tswj hwm yog ua los ntawm kev cai lij choj thiab Arduino Nano, hnav ntawm lub taub hau. Lub Circuit Court no muaj ob lub hauv paus tseem ceeb: lub peev xwm kov tau lub ntsej muag lub ntsej muag, thiab lub tshuab tsav hluav taws xob rau hloov lub zog rau lub braid. Kev lag luam plaub hau txuas ntxiv yog braided ib ncig ntawm cov hlau nitinol, uas yog lub cim xeeb zoo nkauj. Cov hlau no yuav tuav ib lub cev thaum txias, thiab txav mus rau qhov zoo thib ob thaum ua kom sov. Peb tuaj yeem qhia yuav luag txhua qhov zoo thib ob rau hauv xaim (piav qhia tom qab hauv Phau Ntawv Qhia no). Ob lub roj teeb LiPo siv lub zog tswj ntawm 5V, thiab plaub hau ntawm 3.7V.

Kauj ruam 2: Electronics

Tswj thiab Capacitive Touch

Lub peev xwm kov lub xov tooj tau hloov pauv los ntawm Disney's Touché project, dhau ntawm qhov qhia tau zoo ntawm kev rov ua dua Touche ntawm Arduino. Cov teeb tsa no txhawb nqa qhov ua kom muaj peev xwm kov tau qhov hnov tau zoo, thiab tso cai rau ua kom paub piav tes piav taw ntau dua li kov yooj yim/tsis kov. Ib qho lus ceeb toom ntawm no yog qhov muaj peev xwm kov tau Circuit Court thiab code xav tias tshwj xeeb Arduino nti, Atmega328P. Yog tias koj xaiv siv lwm txoj kev tswj hwm microcontroller, koj yuav xav rov tsim tus lej, lossis nrhiav lwm txoj hauv kev rau kev paub.

Kev tswj hluav taws xob siv Arduino Nano rau cov laj thawj, thiab cov sib piv sib piv kom tso cai tswj tau ntau yam braids tawm tib lub xov tooj cua thiab roj teeb. Capacitive kov tau hnov yuav luag ib txhij los ntawm kev hloov pauv sai ntawm cov channel (nrawm heev uas nws ib txwm zoo li peb tau hnov ob qho tib si ib zaug). Kev ua ntawm braids yog txwv los ntawm lub zog muaj. Xws li muaj zog ntau dua, lossis cov roj teeb ntxiv tuaj yeem ua kom muaj kev sib koom ua ke, txawm li cas los xij ntawm no peb txwv nws mus rau qhov ua haujlwm txuas ntxiv kom yooj yim. Cov phiaj xwm hluav taws xob tau muab tuaj yeem tswj tau ob lub braids (tab sis tus lej sib npaug hauv Circuit Court tuaj yeem txhawb nqa txog plaub!)

Rau qhov yooj yim tshaj plaws ntawm lub Circuit Court, tawm tus multiplexer tawm, thiab tswj ib zaug braid ncaj qha los ntawm Arduino.

Tsav Circuit Court thiab Thermistor

Peb ua qhov kov tau ntawm tib lub xaim li kev ua haujlwm (nitinol). Qhov no txhais tau tias tsawg dua cov xov hlau/qhov nyuaj hauv txoj hlua, thiab ntau ntxiv hauv Circuit Court.

Cov tsav hluav taws xob muaj cov txheej txheem bipolar hlws ris transistors (BJTs) los hloov cov plaub hau ua rau thiab tawm. Nws yog qhov tseem ceeb uas cov no yog bipolar kev sib tshuam transistors, ntau dua li qhov ntau (thiab feem ntau zoo dua) MOSFETs, vim tias BJTs tsis muaj lub peev xwm sab hauv. Lub peev xwm sab hauv ntawm MOSFET yuav dhau mus rau qhov kov qhov cuam tshuam hauv Circuit Court.

Peb kuj tseem yuav tsum tau hloov pauv hauv av thiab lub zog, tsis yog tsuas yog lub zog, ib zaug ntxiv rau qhov xav tau ntawm lub peev xwm kov tau zoo, vim tias tsis muaj lub cim hluav taws xob los ntawm lub hauv paus hluav taws xob.

Lwm txoj kev tsim qauv uas siv cais cov peev txheej rau kov lub peev xwm thiab tsav tsheb tuaj yeem ua kom yooj yim rau cov khoom siv hluav taws xob no, txawm li cas los xij nws ua rau cov qauv siv tshuab nyuaj dua. Yog tias lub peev xwm nkag siab tau raug cais los ntawm lub zog rau tsav, peb tuaj yeem tawm mus nrog kev hloov pauv ib zaug rau lub zog, thiab nws tuaj yeem yog FET lossis lwm yam. Cov kev daws teeb meem no tuaj yeem suav nrog ua cov plaub hau nws tus kheej, zoo li hauv Katia Vega Cov Plaub Hau.

Bluetooth nti

Lub bluetooth nti peb siv yog Bluefruit Phooj ywg los ntawm Adafruit. Cov qauv no yog nyob ntawm tus kheej, thiab tsuas yog xav tau txuas nrog Arduino, uas yuav daws cov laj thawj ib puag ncig kev sib txuas lus.

Xaiv Roj Teeb

Txog cov roj teeb, koj xav tau cov roj teeb rov tau uas tuaj yeem muab hluav taws xob txaus rau lub zog Arduino, thiab txaus tam sim no los tsav nitinol. Cov no tsis tas yuav yog tib lub roj teeb. Qhov tseeb, kom tsis txhob muaj xim av tawm ntawm Arduino, peb tau ua tag nrho peb thawj qhov qauv nrog ob lub roj teeb: ib qho rau kev tswj hwm, thiab ib qho rau tsav.

Arduino Nano xav tau tsawg kawg 5V, thiab nitinol thim qhov siab kawg ntawm kwv yees li 2 Amps.

Peb tau xaiv lub roj teeb 3.7 V los ntawm ValueHobby los tsav cov plaub hau, thiab lub roj teeb 7.4V los ntawm ValueHobby kom muaj zog rau Arduino. Sim tsis txhob siv roj teeb 9V li niaj zaus; lawv yuav ntws qis dua qhov muaj txiaj ntsig hauv 15 feeb thiab ua rau pov tseg ntau. (Peb paub, vim tias peb tau sim …)

Lwm Yam Lus Qhia

Kev saib xyuas roj teeb: 4.7k Ohm resistor nruab nrab ntawm txoj kab hluav taws xob ntawm lub roj teeb tsav thiab tus pin piv cia peb saib xyuas tus nqi ntawm lub roj teeb tsav. Koj xav tau tus tiv thaiv no kom lub roj teeb tig los ntawm Arduino ntawm tus pin analog (uas yuav tsis zoo: koj tsis xav ua qhov no). Lub roj teeb Arduino tuaj yeem saib xyuas nrog tus lej nkaus xwb - saib ntu ntawm software rau kev tshem tawm tus lej no.

Jumper: Muaj qhov chaw rau jumper nruab nrab ntawm ob lub roj teeb sib txuas, yog tias koj xav siv lub roj teeb ib leeg los txhawb txhua yam. Qhov no txaus ntshai xim av tawm ntawm Arduino, tab sis nrog xaiv roj teeb kom raug thiab qee qhov software-raws PWM ntawm tus tsav, nws yuav tsum ua haujlwm. (Txawm hais tias peb tseem tsis tau txais nws.) (Yog tias koj sim nws - qhia rau peb paub tias nws mus li cas!)

Kauj Ruam 3: Cov Khoom Siv Hluav Taws Xob

Muab lub Circuit Court ua ke

Peb tsim cov phiaj xwm hluav taws xob thawj zaug hauv ob ntu, txuas lub zog tsav thiab tswj cov kab hluav taws xob nrog cov kab hloov pauv tau. Hauv peb cov PCB sib xyaw ua ke, cov kab hluav taws xob tau muab tso rau hauv ib lub rooj tsavxwm. Cov phiaj xwm qub tso cai rau hloov pauv yooj yim dua ntawm braids ntawm lub taub hau, tab sis qhov thib ob yog qhov yooj yim dua rau sib sau ua ke. Koj tuaj yeem pom cov phiaj xwm phiaj xwm thiab teeb tsa cov ntaub ntawv hauv peb Github repo. Muaj ob txoj hauv kev los ua cov kab hluav taws xob: 1) tes-ua cov ntawv sib xyaw ua ke nrog cov khoom sib dhos ua ke raws li cov txheej txheem, lossis 2) ua PCB los ntawm cov ntawv hauv pawg thawj coj saib peb muab (txuas saum toj no) thiab sib sau ua ke nrog ntu ntu ntu.

Cheebtsam

Cov nqi ntawm cov ntaub ntawv rau PCB version + braids nyob ntawm no.

Peb milled peb qhov kev xeem PCBs peb tus kheej ntawm Lwmmill, tom qab ntawd xaj peb cov PCBs kawg los ntawm Bay Area Circuit Circuit zoo tshaj. Kev tsim khoom hauv tsev thiab kws tshaj lij yuav ua haujlwm tau zoo, txawm hais tias siv tes plating lossis siv tag nrho cov vias yog qhov mob.

Lub tswv yim

• Peb siv cov laug muab tshuaj txhuam thiab lub qhov cub rov qab los yog lub phaj kub rau cov khoom ntim saum npoo, tom qab ntawd muab cov khoom hla dhau los ntawm tes.

• Peb siv tus poj niam luv lub taub hau los tuav Nano ntawm PCB, yog li nws tuaj yeem tshem tau. Cov poj niam ntev lub taub hau tuaj yeem muab tso rau hauv qhov tsis zoo-ntws mus rau pawg thawj coj saib kom rub lub bluetooth nti siab txaus rau zes saum Arduino. (Koj tseem yuav xav ntxiv Kapton daim kab xev txhawm rau tiv thaiv kev ua yuam kev luv).
• Lub bluetooth nti tiag tiag yuav tsum tau muab muag rau nws tus txiv neej lub taub hau upside-down thiaj li yuav phim tus pin xaj ntawm PCB txheej txheem. (Tau kawg, koj tuaj yeem hloov kho qhov txheej txheem no.) Vim li cas peb thiaj ua li ntawd? Vim tias nws ua rau cov koob sib dhos tau zoo dua rau Arduino kev teeb tsa.

Kauj Ruam 4: Cov Txheej Txheem Plaub Hau

HairIO yog cov plaub hau txuas ntxiv txuas ib puag ncig ob qhov txuas ntawm cov xov hlau, txuas rau lub txuas thiab lub ntsuas cua rau ntsuas kub. Nws tuaj yeem chalked nrog cov xim thermochromic tom qab sib dhos tag nrho. Ua HairIO braid nws tus kheej muaj ntau theem:

1) Qhia cov duab cim xeeb kom zoo rau lub siab xav.

2) Sib sau ua ke cov xaim sab hauv los ntawm crimping thiab soldering qhov ntev ntawm cov duab cim xeeb hlau rau insulated tooj liab hlau.

3) Crimp thiab insulate lub thermistor.

4) Txuas cov xaim thiab cov thermistor rau lub txuas.

5) Braid plaub hau nyob ib ncig ntawm cov xov hlau.

6) Chalk cov plaub hau.

Peb yuav hais txog txhua theem ntawm kev nthuav dav hauv ntu hauv qab no.

Kauj Ruam 5: Sib dhos Cov Hluav Taws Xob

Thawj theem koom nrog sib dhos cov xov hlau sab hauv uas muab hloov pauv thiab tiv thaiv cua sov. Nov yog qhov uas koj txiav txim siab qhov ntev ntawm txoj hlua, qhov xav tau zoo li cas thaum nws raug rhaub, thiab hom txuas uas koj yuav siv. Yog tias tag nrho cov braids muaj hom sib txuas sib txuas, lawv tuaj yeem hloov pauv tau yooj yim ntawm tib lub rooj sib tham hauv Circuit Court rau ntau yam duab thiab xim ua, nrog rau hom thiab qhov ntev ntawm cov plaub hau.

Yog tias koj tsis xav hloov cov duab hauv ib qho tshwj xeeb braid, lub cim xeeb zoo tuaj yeem hloov pauv nrog qhov ntev ntawm cov xov hlau tsis tu ncua. Yog tias koj xav txhawb kev muaj peev xwm kov, hloov cov xaim yuav tsum tsis muaj qhov ntsuas kom zoo tshaj plaws.

Kev cob qhia Cov Duab Cim Alloy

Cov duab cim xeeb hlau uas peb siv ntawm no yog nitinol, nickel-titanium alloy. Thaum txias, nws tseem nyob hauv ib tus duab, tab sis thaum rhaub nws rov qab mus rau qhov uas hu ua "kev kawm" lub xeev. Yog li yog tias peb xav tau braid uas curls thaum ua kom sov, nws yuav ncaj thaum txias, tab sis tau txais kev cob qhia rau cov plaub hau. Koj tuaj yeem tsim yuav luag txhua yam duab uas koj xav tau, txawm hais tias lub peev xwm ntawm cov hlau nqa qhov hnyav tau txwv los ntawm nws txoj kab uas hla.

Txiav cov nitinol mus rau qhov ntev xav tau ntawm txoj kab, tso me ntsis ntxiv rau qhov nkhaus thaum lub caij braiding, thiab rau kev sib txuas saum toj thiab hauv qab.

Txhawm rau qhia nitinol, saib qhov Qhia Zoo Tshaj Plaws.

Hom braid peb tau sim nrog suav nrog curls, txoj cai-khoov kom cov plaub hau sawv ncaj, thiab tsis qhia nitinol txhua. Qhov no yuav zoo li tub nkeeg, tab sis nws tso cai rau cov plaub hau kom ncaj tawm ntawm cov duab thaum ua haujlwm. Cov xaim yuav tuav tus qauv uas koj khoov rau thaum txias, piv txwv. ib qho curl, tom qab ntawd ncaj tawm ntawm cov duab ntawd thaum ua kom sov. Super txias, thiab yooj yim dua!

Sib dhos Cov Xov

Cov nitinol tsis muaj qhov ntsuas, thiab tsuas yog khiav hauv ib qho nkaus xwb. Txhawm rau tsim kom muaj kev sib tw tiav, peb xav tau qhov thib ob, cov xaim hluav taws xob txuas rau hauv qab thiab rov qab mus rau qhov txuas sab saum toj. (Cov xov hlau tsis muaj kab xev yuav ua rau luv Circuit Court thaum nws kov cov nitinol, thiab tiv thaiv kom tsis txhob muaj cua sov.)

Txiav qhov ntev ntawm cov xov tooj tooj liab thaiv kom zoo ib yam li nitinol. Peb siv 30 AWG hlau nplaum hlau. Tshem cov rwb thaiv tsev ntawm ob qho kawg. Rau cov hlau nplaum hlau, cov txheej tuaj yeem tshem tawm los ntawm maj mam hlawv cov hlau nrog cov nplaim taws qhib kom txog thaum cov ntawv rwb thaiv tsev thiab tuaj yeem muab pov tseg (uas siv sijhawm li 15 vib nas this w/ sib dua). Nco ntsoov tias qhov no ua rau cov hlau tawg me ntsis ntawm qhov chaw hlawv.

Qhov tseeb lom zem txog Nitinol: Hmoov tsis zoo, cov laug tsis nyiam lo rau nitinol. (Nws yog qhov mob hnyav.) Qhov kev daws teeb meem zoo tshaj plaws yog siv cov crimp los tsim cov khoom siv sib txuas rau nitinol, tom qab ntawd ntxiv cov laug kom ntseeg tau tias muaj kev sib txuas hluav taws xob.

Tuav qhov kawg ntawm nitinol thiab cov tooj liab uas tsis tau muab pov tseg tshiab ua ke, thiab ntxig rau hauv ib qho crimp. Crimp lawv solidly ua ke. Yog tias xav tau kev txuas ntxiv ntxiv, ntxiv me ntsis ntawm cov laug. Npog lub crimp thiab ib qho seem ntawm cov hlau nrog cua sov kom koj tus neeg hnav tsis ua rau lawv tus kheej nrog qhov xaus. Nws tsis muaj teeb meem dab tsi ntawm crimp koj siv hauv qab, txij li nws tsuas yog ua kom muaj kev sib txuas sib txuas ntawm ob lub xov hlau.

Ntawm qhov kawg, peb yuav ntxiv cov crimp rau txhua qhov xov hlau. Ntawm no, hom crimp teeb meem. Koj yuav tsum siv tus mating crimp rau koj tus txuas. Cov xaus ntawm cov xov hlau no yuav raug txuas rau qhov txuas rau cuam tshuam nrog lub rooj tsav xwm hauv Circuit Court.

Ua kom Stand-Up Braid:

Cov braids tuaj yeem hloov maj mam, lossis ua tau zoo heev. Yog tias koj xav tau cov txiaj ntsig zoo, raws li daim duab taub hau saum toj no, lossis hauv qhov xwm txheej ua yeeb yaj kiab video ua ntej, yuav tsum muaj ib kauj ruam ntxiv. Cov braids xav kom sib tw ntau dua li nqa, yog li lawv yuav tsum tau braced kom nyob hauv qhov kev qhia raug. Peb txoj hlua khiab mis zoo li lub ncab Z (rub tawm hauv daim duab). Peb swb ib qho crimp ntawm nitinol, tom qab ntawd muab cov hlua khi rau lub crimp, thiab thaum kawg npog tag nrho cov khoom hauv tshav kub ntsws thiab kab xev hluav taws xob.

Npaj Thermistor

Lub thermistor yog lub ntsuas cua sov-tiv taus uas cia peb ntsuas qhov kub ntawm txoj hlua. Peb siv qhov no txhawm rau kom ntseeg tau tias braid tsis tau kub dhau rau tus neeg siv hnav. Peb yuav ntxiv cov thermistor rau tib qhov txuas uas cov hlua yuav txuas nrog.

Ua ntej, xaub cov cua sov ntswj mus rau ob txhais ceg ntawm cov thermistor thiab siv rab phom cua sov kom txo nws. Qhov no yuav tiv thaiv ob txhais ceg, txhawm rau tiv thaiv cov thermistor los ntawm kev luv mus rau cov tshuaj tsis muaj nitinol. Tso me ntsis xaim tawm ntawm qhov kawg rau crimp. Ib zaug ntxiv, cov crimps no yuav tsum yog qhov tsim nyog rau koj txuas.

Crimp qhov kawg ntawm cov thermistor. Yog tias koj tuaj yeem ua tau, kom sov me ntsis rau hauv thawj cov hniav ntawm crimp raws li nyem nyem. Txawm li cas los xij, tsis txhob tso nws dhau mus, txij li cov xov hlau yuav tsum tseem txuas rau kev txuas hluav taws xob zoo.

Tam sim no lub thermistor tau npaj txhij los txuas rau lub txuas.

Sib dhos Cov Txuas Txuas

Koj tuaj yeem siv txhua yam ntawm 4-lub davhlau ya nyob twg txuas rau sab saum toj ntawm braid; tom qab qee qhov kev sim, peb txiav txim siab ntawm Molex Nanofit txuas. (Nov yog qhov peb PCB siv.) Lawv muaj cov ntaub ntawv qis ntawm lub rooj tsav xwm hauv Circuit Court, cov khoom siv sib txuas nrog cov clip kom lawv xauv rau hauv, tab sis tseem yooj yim rau ntxig thiab tshem tawm.

Cov Nanofit txuas mus ua ke hauv peb theem:

Ua ntej, ntxig rau ob qhov kawg ntawm lub thermistor rau hauv ob lub qhov nruab nrab ntawm cov txiv neej ib nrab ntawm qhov txuas.

Tom ntej no, ntxig rau ob qhov ua rau sab saum toj kawg nkaus ntawm txoj hlua khi rau sab laug-feem ntau thiab txoj cai-feem ntau cov khoom ntawm tus txiv neej ib nrab ntawm qhov txuas.

Thaum cov no nyob hauv qhov chaw, ntxig tus tuav tuav rau hauv qhov chaw tso khoom. Qhov no pab tuav cov crimps nyob rau hauv qhov chaw kom cov braid tsis rub tawm qhov txuas.

Tus poj niam ib nrab ntawm qhov txuas yog ntawm lub rooj tsav xwm hauv Circuit Court, thiab txuas cov plaub hau txuas mus rau lub tshuab tsav thiab lub ntsej muag kov lub ntsej muag, thiab lub thermistor lub dav hlau mus rau Arduino rau qhov ntsuas kub.

Npaj Mus

Tam sim no, cov xaim tau npaj kom tau braided.
