• LED Tshuab Ntsuas Hluav Taws Xob (txhawm rau txiav txim siab tus nqi tiv thaiv raws li tam sim no thiab lub zog siv)
• Fais fab thiab ntsuas tam sim no

Cov ntaub ntawv no tau tshaj tawm los ntawm kev sib txuas ntawm APIs thiab khoos phis tawj sensors. Kuv txhawb nqa ESP32 rau lub microcontroller, thiab txhawb nqa AWS Cloud rau txhua qhov kev khaws cov ntaub ntawv thiab kev sib sau ua ke.

Kuv kuj suav nrog ob peb "Easter qe":

• Ron McNair kev hwm - Dr McNair yog qhov laj thawj kuv dhau los ua tus kws tshaj lij; nws loj hlob 45 feeb los ntawm kuv lub nroog. Nws tuag hauv Challenger tawg.

  • Lub npe ntawm kuv lub hnub qub nkoj yog "USS Ronald E McNair"
  • Tus Zauv Sau Npe yog los ntawm Sr McNair lub hnub yug; Txoj Cai Ua Ntej yog hnub nws poob nws txoj sia.
• Kev siv "tus lej ua ntej" yog lub ntsej muag rau Star Trek: Kev npau taws ntawm Khan (qhov zoo tshaj plaws Star Trek movie txhua lub sijhawm; tsis txhob @ kuv).
• Cov naj npawb ntawm txoj cai ntawm rooj plaub dav dav hais txog kuv kev sib koom ua ke (1906 - Alpha Phi Alpha) thiab kuv tus niam tsev thiab kev kawm - (University of Oklahoma, College of Engineering)

Koj muaj qhov kev xaiv ntawm kev kho tus lej, tus ntawv, thiab lub npe nkoj, sau npe, thiab lwm yam rau koj tus kheej "Easter qe".

Keeb kwm yav dhau

Xyoo tas los, Kuv xav tau txoj hauv kev qis los ntsuas lub zog thiab lub roj teeb ntws rau txoj haujlwm hnav. Kuv tau yuav Adafruit INA219 Featherwing, thiab siv qee qhov khoom siv sib txawv los tsim cov cuab yeej ntsuas lub zog yooj yim (koj tuaj yeem nyeem ntxiv txog nws ntawm no).

Xyoo no, Kuv txiav txim siab hloov kho lub cuab yeej… kom nws ntau dua “techy”. Kuv xub npaj tsim lub Star Trek tricorder ua haujlwm (Mark IV TR-590 Mark IX version, rau cov uas saib xyuas) … mus rau txhua qhov teeb meem no los ua lub cuab yeej txias, tsuas yog kaw nws thiab muab tso rau hauv lub tub rau khoom thaum tsis siv).

Yog li, kuv tau tig los ua lub khoos phis tawj hais tawm uas koj pom ntawm Star Trek TNG lossis Voyager (lossis cov yeeb yaj kiab sib txawv). Kuv tau ua si ib puag ncig nrog cov qauv sib txawv, tom qab ntawd hla hla qhov tsim los ntawm Ruiz Cov Kwv Tij ntawm Adafruit. Adafruit ua haujlwm zoo ntawm kev muab cov ntaub ntawv rau lawv cov phiaj xwm 3D luam tawm, yog li kuv muaj peev xwm coj lawv cov ntawv qub thiab rov ua nws rau kuv kho vajtse, khawm, thiab lwm yam khoom siv ib puag ncig.

Yam yuav tsum paub ua ntej koj mus txuas ntxiv
