Txog: Tus kws tshawb fawb ua haujlwm hauv kev kuaj mob hauv vitro. Ua si nrog txhua yam ntawm lub sensor ua lub sijhawm nyiam ua haujlwm. Lub hom phiaj rau cov cuab yeej yooj yim thiab tsis kim thiab cov haujlwm rau STEM, nrog rau kev tshawb fawb me ntsis thiab me ntsis … Ntau Txog Dr H »

Kuv tau pib ua haujlwm ntawm lub tswv yim no hauv xyoo 2018, yog qhov txuas ntxiv ntawm txoj haujlwm yav dhau los, xim xim. Kuv qhov kev xav tau yog siv cov ntawv e-ntawv, yog li cov xim ntsuas tuaj yeem siv los ua kev daws teeb meem ib leeg yam tsis muaj qhov yuav tsum tau ua rau sab nraud saib, xws li rau chav kawm lossis daim ntawv thov siv.

Kuv muaj qee lub sijhawm los ua si ntawm txoj haujlwm dhau los ntawm Christmas so 2018/2019, tab sis, txawm tias cov ntawv sau qhia tau sau tseg lawm, qee yam uas kuv npaj yuav ua tseem tsis tau muaj. Tom qab ntawd kuv yuav tsum mob siab rau txoj haujlwm ntxiv, yuav tsum ua tiav kuv cov haujlwm nyob ntawd thiab pib ua haujlwm tshiab thaum lub Plaub Hlis. Yog li kuv tsis muaj sijhawm ntau rau cov phiaj xwm dag rau ib pliag, thiab thaum kawg txoj haujlwm hauv qab no tau dhau los ua ib qho ntawm ntau lub tswv yim thiab cov ntsiab lus hibernating hauv kuv qhov me me "Bastelecke" ("kaum tinker"?), Raug cuam tshuam txij li Lub Ib Hlis 2019.

Yog tias nws yuav tsis yog rau "Ua tiav nws twb tau" kev sib tw, cov lus qhia no tseem yuav tsis tau tshaj tawm rau ntau xyoo.

Yog li hnub Peetekos 2020 tab tom los txog tam sim no, Kuv txiav txim siab los hloov qee qhov kev hloov pauv mus rau qhov kev qhia ua cov ntawv thiab cov qauv, thiab tshaj tawm nws.

Thiab tej zaum kuv yuav pom lub sijhawm los tsim vaj tsev rau lub cuab yeej thiab ua cov kev ntsuas enzyme kinetics uas kuv xav nthuav tawm ib hnub. Lossis koj yuav ua qhov ntawd ua ntej kuv.

Zoo Siab Tinkering

----------------------------------------------------------------------- -------------------------------------- Hauv cov lus qhia no kuv xav piav me me, pheej yig thiab lub xov tooj ntawm tes rau lub tshuab ntsuas hluav taws xob sib xyaw ua ke ntawm Raspberry Pi Zero nrog Inky pHAT e-ink zaub, AS7262 rau xim xim tawg, tus tuav lub cuvette thiab qee cov nyees khawm, LEDs thiab cables.

Txhawm rau sib sau ua ke lub cuab yeej tsis xav tau ntau yam txuj ci tshwj xeeb lossis cov cuab yeej saum toj no cov kab laug sab ntawm lub taub hau. Cov cuab yeej yuav yog qhov txaus siab rau kev kawm, nyiam ua lossis pej xeem daim ntawv thov kev kawm thiab tuaj yeem yog qhov haujlwm STEM zoo.

Hauv kev teeb tsa piav qhia ntawm no, cov lus qhia thiab ntsuas ntsuas tau tshwm rau ntawm e-ink zaub thiab ntawm kev xaiv lub computer tso saib. Cov txiaj ntsig ntawm kev ntsuas kuj tseem khaws cia hauv CSV-cov ntaub ntawv ntawm SD daim npav ntawm RasPi, tso cai txheeb xyuas cov ntaub ntawv tom ntej.

Hloov chaw ntawm Inky pHAT koj tuaj yeem siv lwm cov lus ib yam nkaus. Tab sis e-ink zaub muaj ntau cov txiaj ntsig, suav nrog kev siv hluav taws xob tsawg heev thiab muaj peev xwm ua tau zoo txawm tias nyob hauv nruab hnub nrig, tso cai tsim cov cuab yeej rau hauv daim ntawv thov uas tuaj yeem ua haujlwm tau teev los ntawm lub hwj chim pob lossis roj teeb.

Kuv tab tom siv AS7262 rau channel xim xim. Qhov ntsuas no ntsuas qhov siv ntawm lub teeb pom kev sib txawv (~ 40 nm) thoob plaws qhov pom pom, npog cov xim liab (450 nm), xiav (500 nm), ntsuab (550 nm), daj (570 nm), txiv kab ntxwv (600 nm)) thiab liab (650 nm). Qhov no tso cai ntsuas ntau dua piv rau RGB-sensors raws li TCS34725. Ib qho kev txwv me me yog ob peb thaj tsam ntawm qhov pom pom, xws li cyan, tsis zoo npog. Tab sis vim tias feem ntau cov xim yuav muaj qhov nqus tau dav, qhov teeb meem no yuav tsum tsis cuam tshuam nrog rau feem ntau daim ntawv thov.

Qhov kev zov me nyuam tau sau hauv Python3 thiab siv Adafruit Blinka thiab AS7262 cov tsev qiv ntawv ntxiv rau Pimoroni Inky pHAT thiab GPIOzero cov tsev qiv ntawv. Yog li nws yuav tsum yooj yim los hloov kho thiab ua kom zoo dua tsab ntawv rau koj daim ntawv thov tshwj xeeb.

Raws li ob peb ntu thiab cov ntsiab lus twb tau piav qhia hauv cov lus qhia yav dhau los, Kuv nyiam xa mus rau cov no rau qee cov ntsiab lus lossis kev xaiv txheej txheem.
