Qhov no yog dab tsi? Qhov ntsuas ntau dua plaub npaug ntawm qhov ntsuas hluav taws xob tsawg, pab txhawb rau lub ntiaj teb ntsuab dua vim tias nrog kev pab los ntawm cov cuab yeej me me no ntau cov khoom siv hluav taws xob tawg tuaj yeem tau txais lub neej thib ob lossis thib peb, thiab yuav tsis raug xa mus rau lub thoob khib nyiab!

Kev ceeb toom kev nyab xeeb: Ceev faj txhua yam koj sim, lub cuab yeej tsuas tuaj yeem siv los ntsuas lub cuab yeej nrog kev nyab xeeb qis hauv.

Tsis txhob siv nws txuas rau qhov hluav taws xob txaus ntshai!

Kauj Ruam 1: Kho Café

Qhov chaw zoo tshaj plaws los siv tus ntsuas plaub npaug no nyob qhov twg? Ntawm Kho Café!

Kho Café yog rooj sib tham uas tib neeg kho cov khoom siv hluav taws xob thiab khoom siv hauv tsev, khoos phis tawj, tsheb kauj vab, khaub ncaws, thiab lwm yam. Lawv tau teeb tsa los ntawm thiab rau cov neeg nyob hauv zos. Kho Cafés tau tuav ntawm qhov chaw ruaj khov uas muaj cov cuab yeej thiab qhov uas lawv tuaj yeem kho lawv cov khoom tawg nrog kev pab los ntawm cov neeg pab dawb. Nws lub hom phiaj yog txhawm rau txo cov pov tseg, kom muaj kev txawj nyob ib puag ncig kho thiab txhawb kev sib raug zoo hauv zej zog.

Kauj Ruam 2: Yuav Ua Li Cas Tsim Lub Suab Amplifier

Daim ntawv teev cov khoom rau lub tshuab ua kom nrov no: 1 Velleman cov khoom siv hom K40011 potentiometer 10 kOhm1 pob rau lub zog potentiometer1 resistor 100 kOhm 1/8 Watt1 resistor 100 Ohm 1/8 WattThe audio amplifier is a K4001 kit from Velleman, a 7 Watt mono amplifier. Follow this link thiab koj yuav pom txhua cov ntsiab lus tseem ceeb. (cov lus qhia sib dhos, cov npe khoom thiab lwm yam).

Raws li qhia hauv daim duab kab lus, kuv tau ntxiv 100 Ohm resistor ntawm qhov tso tawm kom txwv lub zog rau lub mloog pob ntseg kuv siv, (lawv tsis xav tau 7 Watt). Thiab kuv tau ntxiv lub hwj chim ntsuas (10kOhm) thiab cov tshuaj tiv thaiv kab mob ntawm 100 kOhm ntawm cov tswv yim los kho lub suab thiab txwv qhov cuam tshuam ntawm lub tshuab raj rau ntawm qhov ntsuas qhov kawg. lwm qhov amplifier yuav tsis haum rau hauv lub thawv yas.

Kauj Ruam 3: Yuav Ua Li Cas Tsim Lub Suab Teeb Meem Generator

Daim ntawv teev cov npe rau lub tshuab hluav taws xob teeb liab no: 1 ntu me me qauv PCB2 resistors 47 kOhm1/8 Watt1 resistor 100 kOhm 1/8 Watt2 capacitor 10 nF1 capacitor 10 uF1 IC hom NE555Tsis siv lub tshuab hluav taws xob no ua rau me me thaiv hom teeb liab nrog qhov ntau ntawm appr. 1 kHz, koj tuaj yeem siv nws xa mus rau qhov khoom ntsuas thiab ua raws lub teeb liab ntawm lub tshuab hluav taws xob ib feem ntawm tus ntsuas. Koj tuaj yeem pom ntau NE555 daim ntawv thov ntawm lub vev xaib qhia, tsuas yog tshawb nrhiav 555 kom pom zillion piv txwv.. See qhov txuas no:

Kauj Ruam 4: Yuav Tsim Li Cas Tester thiab LED Tester

Daim ntawv teev npe rau qhov ntsuas hluav taws xob no thiab ntsuas tester: 2 resistors 1 Mohm 1/8 Watt1 resistor 100 kOhm 1/8 Watt3 resistors 1 kOhm 1/8 Watt1 resistor 10 kOhm1 ntsuab LED 5 mm1 liab LED 5 mm1 buzzer 9V DC1 capacitor 10 nF1 ON /OFF hloov 1 lub roj teeb 9V1 transistor BC547 (NPN) 1 transistor BF472 (PNP) 1 ntu me me qauv PCB Tus xov tooj hluav taws xob tester yog qhov nkag siab heev thiab muaj qhov cuam tshuam tsis zoo thiab yuav pom lub teeb ntsuab ntsuab (ntawm BF472 transistor) thaum cov tswv yim txuas nrog GND. Nws muaj lub zog me me thib ob (BC547 transistor) los qhib lub buzzer. Qhov ntsuas muaj ntxiv 1 kOhm resistor, txuas nrog VCC 9V DC los ntsuas LED's. LED tuaj yeem txuas nrog ntawm tus tiv thaiv no (txuas nrog lub ntsaws ntsaws dawb) thiab GND (txuas nrog lub ntsaws ntsaws dub).

Kauj Ruam 5: Txhim Kho Txhua Yam Ua Ke

Cov npe khoom: 1 lub thawv yas 5 tus poj niam ntsaws rau 6 hli txiv tsawb ntsaws (liab, ntsuab, dawb, xiav, dub) 1 tus poj niam ntsaws rau 3.5 hli lub tso suab pob ntseg txuas. Tsim kom muaj peb lub voj voos sib cais (lub tshuab hluav taws xob, lub tshuab ntsuas hluav taws xob thiab lub tshuab hluav taws xob teeb tsa) rau hauv lub thawv yas me. Txuas cov txuas hauv qab no rau 6 hli txiv tsawb ntsaws rau ntawm ib sab: RED: audio INWHITE: LED testBLUE: Kev ntsuas hluav taws xob GREEN: Lub teeb liab tawm BLACK: Hauv av Ib qho lwm sab koj tuaj yeem txuas lub 3.5 hli ntsaws rau kev txuas ntawm lub pob ntseg ntawm lub tshuab ua suab nrov. Yog hloov lub quadruple tester ON thiab OFF tso ON/OFF hloov ntawm ib sab ua ke nrog liab ON/OFF xwm txheej LED. Ntau lub pob qhov rooj rau lub suab theem potentiometer tau muab tso ua ke, nrog rau lub suab nrov thiab cov thaiv ntsuab pom kev coj.

Kauj Ruam 6: Koj Yuav Xeem Dab Tsi?

Koj tuaj yeem xeem dab tsi?

Ntawm qhov txuas txuas xiav: Txuas! Koj tuaj yeem sim txhua hom kev txuas hluav taws xob. Yeej nws yog qhov ntsuas hluav taws xob tiv thaiv siab nrog lub suab nrov thiab LED ntsuab los txheeb xyuas qhov tooj liab txuas tsis tau ntawm cov ntawv xov xwm hluav taws xob luam tawm thiab tsis txuas xov. Vim tias nws nrov nrov heev koj tuaj yeem khaws koj lub qhov muag ntawm qhov chaw xeem. Ntawm qhov txuas txuas dawb: LED! Yuav luag txhua hom LED tuaj yeem kuaj yam tsis muaj kev txhawj xeeb txog cov tshuaj tiv thaiv kab mob. Nws yog 9 Volt DC txuas nrog tus lej txuas ntawm 1000 Ohm. Ntawm tus liab txuas: Suab! Ntawm no koj tuaj yeem mloog cov cim hluav taws xob sab hauv lub cuab yeej koj tab tom sim, nrog koj lub pob ntseg me me.

Ntawm qhov txuas ntsuab: Lub suab ntsuas lub suab. Qhov no koj muaj lub suab ntsuas lub suab (thaiv hom) piv txwv los ntsuas lub Circuit nrog lub suab nrov. Cov txuas dub: Hauv av txuas.

Kauj Ruam 7: Hloov Kho Xyoo 2020

Kuv tau hloov kho tus ntsuas kom ntsuas cov xov txuas ntev, piv txwv li UTP cables hauv tsev network.

Kuv ntxiv ib tus poj niam txiv tsawb txuas ntxiv (daj ib qho) ntawm ib sab ntawm lub npov, txuas ncaj qha mus rau lub zog ntawm lub suab nrov. Thaum koj txuas lub suab tso tawm suab (lub ntsaws liab) nrog lub suab tso tawm lub tshuab hluav taws xob (lub ntsaws ntsuab) qhov kev sib txuas daj no tuaj yeem xa lub suab zoo rau hauv kab uas koj xav sim. Tsuas yog txuas lub ntsaws daj thiab dub GND ntsaws rau ob lub xov hlau ntawm lub xov tooj thiab txuas me ntsis ntsuas tus neeg hais lus mus rau lwm qhov kawg ntawm tib lub xov tooj kom hnov lub teeb liab yog tias lub xov tooj ntawm lub xov tooj zoo li cas. Yog tias koj muaj ntau txoj kab hluav taws xob hauv pob loj koj tuaj yeem txheeb xyuas cov kab sib txawv.
