2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:25

Pib xyoo 2009, thawj TR-01 v1.0, v2.0 thiab v2.0 Baro los ntawm TwistedRotors teeb tsa tus qauv rau tes tuav, digital, ntsuas lub cav tig lub cav ntsuas. Thiab tam sim no koj tuaj yeem tsim koj tus kheej!

Rau xyoo 2017, ua kev qhuas 50th Xyoo ntawm Mazdas Rotary Engine thiab xyoo thib 20 ntawm SevenStock, Kuv tab tom tso DIY version ntawm TR-01. Nws yog raws li qhov nrov nrov Arduino kab ntawm micro-controller boards thiab super yooj yim los tsim. Kuj tseem muaj tus nqi dav dav ntawm kev txhawb siab hloov pauv kom koj tuaj yeem ua tus ntsuas no muaj nqis raws li koj nyiam.

Txhawm rau teeb tsa koj li kev ntsuas koj yuav siv Arduino IDE. Kuv tabtom muab cov cai ntawm no pub dawb tsis muaj kev tso cai lossis them nqi. Txaus siab rau! Xav tias dawb ntxiv cov yam ntxwv thiab hloov kho nws hauv txhua txoj kev uas koj xav tau. Tsuas yog qhov kuv nug yog tias koj qhia koj cov cai thiab cov tswv yim nrog zej zog.

Kauj Ruam 1: Cov Cuab Yeej

• Soldering hlau
• Solder
• Wrenches
• RTV
• Teflon yeeb nkab kab xev
• Khoos phis tawj nrog Arduino IDE teeb tsa (Arduino - Software)

Kauj Ruam 2: Qhov Chaw

Nov yog cov npe ntawm cov khoom koj yuav xav tau. Nov yog kuv cov lus pom zoo ntawm tus kheej tab sis kuv tseem teev cov kev xaiv pheej yig dua ib yam. Koj tsis tas yuav siv cov txuas uas kuv muab, koj tuaj yeem yuav cov khoom no los ntawm txhua qhov chaw.

Kauj ruam 3: Tsim Nws

Tam sim no nws yog lub sijhawm los ua cov khoom siv hluav taws xob me me. Kuv xav tias qhov no yog qhov haujlwm zoo heev rau cov pib tshiab tab sis yog tias koj tsis tau muag ib yam dab tsi ces koj yuav xav saib qhov kev qhia no los ntawm cov neeg zoo ntawm Sparkfun.

Ua ntej koj yuav tsim lub tester. Koj yuav pib los ntawm kev siv lub kaum sab xis sab xis rau koj li Arduino Pro Mini. Nov yog qhov FTDI Serial USB cable txuas. Tam sim no muab lub tshuab txuas txuas rau Arduino. Siv cov duab (sensor pinout thiab txuas) txhawm rau txiav txim siab qhov thaiv. Cov hlau cim tias "A" yuav tsum txuas nrog Arduino's "GND" (hauv av) tus pin, "B" txuas nrog "VCC" (5v) thiab "C" yuav txuas nrog "A0" (analog input 0, uas yog ib zero).

Tom ntej no koj yuav tsim lub sensor module nws tus kheej. Yog tias koj siv qhov kev pom zoo Honeywell sensor nws yooj yim li muab cov hlaws ntawm RTV foob rau txhua txoj hauv kev ib ncig ntawm cov xov ntawm lub sensor thiab tom qab ntawd xov rau hauv Spark Plug Tsis-fouler. Zuaj ob qho ua ke nrog koj cov wrenches thiab tom qab ntawd so tawm ntau RTV uas nyem tawm. Teem ib sab thiab cia nws kho yam tsawg 24 teev.

Yog tias koj siv "tus nqi pheej yig dua" eBay sensor (lossis lwm yam ntsuas nrog 1/8 "NPT kawg) ces koj yuav tsum tau xov xov 1/4" NPT Txiv neej mus rau 1/8 "NPT Poj Niam Adapter mus rau sensor nrog teflon daim kab xev thiab tom qab ntawd RTV lub Spark Plug luv Tsis-fouler rau 1/4 "kawg.

Ntxiv o-ring thiab tej zaum qee qhov heatshrink tubing thiab koj ua tiav!

Kauj ruam 4: Program nws

Txuas Arduino board rau koj lub computer siv FTDI cable.

Rub cov ntawv TR01_OS_v01.ino txuas nrog thiab qhib nws siv koj li Arduino IDE.

Hauv "Cov cuab yeej" cov ntawv qhia kom ntseeg tau tias koj tau xaiv lub rooj tsavxwm raug cai, tus txheej txheem thiab chaw nres nkoj xaiv. Yog tias koj siv Arduino Pro Mini ces kuv daim duab piv txwv yuav ua haujlwm rau koj tshwj tsis yog tias koj qhov chaw nres nkoj yuav txawv.

Qhib cov ntawv "Sketch" thiab xaiv "Upload".

Kauj ruam 5: Siv nws

Koj yuav xav xa mus rau FSM rau koj lub tsheb tshwj xeeb kom nrhiav cov lus qhia yuav ua li cas thiaj li ua qhov ntsuas kev ntsuas. Feem ntau, txawm li cas los xij, koj yuav tsum tau kaw koj lub qhov hluav taws kub thiab roj system, tshem tag nrho cov kab hluav taws xob tom qab thiab tom qab ntawd tso lub ntsuas qhov ntsuas qhov ntsuas mus rau hauv lub qhov ntsaws ntsaws ntsaws ntsaws tom qab ntawm lub tsev rotor kom raug sim.

Thaum koj tau txais lub sensor teeb tsa ces koj yuav ntsaws lub tester rau hauv nws thiab tom qab ntawd txuas tus tester rau koj lub computer siv FTDI cable.

Qhib Arduino IDE thiab hauv "Cov cuab yeej" ntawv qhia zaub mov ob zaug uas qhov kev xaiv "Chaw nres nkoj" yog qhov raug thiab tom qab ntawd nyem rau ntawm "Serial Monitor" xaiv.

Thaum tus saib qhib koj yuav tsum teeb tsa tus nqi baud (kaum sab laug) rau 19200 baud. Thaum ua tiav koj yuav tsum pom "TR-01 Open Source" txaws cov ntawv thiab tom qab ntawd koj tau npaj pib qhov kev sim.

Crank lub cav ntau dua thiab koj li TR-01 yuav tso tawm qhov ntsuas ntsuas qhov ntsuas thiab suav RPM hauv "Serial Monitor" qhov rai.

Kauj ruam 6: Bonus

Nov yog qee cov lus qhia, kev pom zoo thiab tswv yim:

• Kuv nyiam Arduino Pro Mini ua ke nrog txoj cai "FTDI Serial TTL-232 USB" cable (Sparkfun lossis Adafruit) vim tias FTDI muaj ib qho app uas yuav tso cai rau koj txuas tus tester rau koj lub xov tooj Android siv USB OTG adapter. Yog tias tsis yog qhov muaj feem thib rau koj ces ib qho Arduino tuaj yeem siv tau.
• Adafruit FTDI Serial TTL cable yog qhov kev xaiv zoo dua vim tias nws txuas tau muaj LED ua hauv yog li koj tuaj yeem pom cov kev sib txuas lus nquag. Kuv txuas rau Sparkfun hauv ntu ntu yog li koj tuaj yeem txuag kev xa khoom.
• Koj yuav tsum muaj peev xwm pom Spark Plug Tsis-ua phem rau ntawm txhua qhov chaw pib tsheb uas nqa Dorman HELP! kab ntawm qhov chaw. Nov yog hauv Asmeskas O'Reillys, Autozone thiab Advance Auto Parts txhua tus nqa lawv.

• Qee qhov tshwj xeeb koj tuaj yeem ntxiv:

  • Bluetooth
  • WiFi
  • LCD Screen
  • Case
  • Tshuab Luam Ntawv
• Kuv npaj yuav txuas ntxiv hloov kho Cov Lus Qhia thiab cov cai no raws sijhawm mus. Kuv yuav zaum ntxiv kev txhawb nqa rau lub vijtsam LCD ua ntej.
• Yog tias koj tsuas yog xav yuav qhov ua tiav, ua tau zoo, teb lub tshuab ntsuas lub zog ntsuas ces koj tseem tuaj yeem tau txais TR-01 v2.0 Baro los ntawm kuv lub xaib. www. TwistedRotors.com
