Lub hnab ntim teeb nyem no ntim ntau dua amphours ib ounce rau hauv koj lub hnab ris tshaj txhua yam uas koj tuaj yeem yuav … yog tias koj twv kom ua ib qho.

Kauj Ruam 1: "Ua lub teeb nyem LED tawm ntawm …"

Koj tau pom lawv. Lawv nthuav tawm zoo li syphilis. Lawv yog Unoriginal LED Teeb nyem Qhia. "Ua lub teeb nyem LED tawm ntawm …": lub thawv Altoids! ib lub thawv Tic Tac! lub thawv Mini Altoids! ib lub ntim roj teeb 9 volt khoob! Altoids cov pos hniav ntim! ib lub khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khawm! ib qho siv cov ntawv tso quav! Zoo, qhov no yog qhov txawv. Nws nyuaj, txaus ntshai, thiab tsuas yog siv sijhawm ntev. Yog li tsis txhob sim qhov no hauv tsev, tshwj tsis yog koj lub npe nruab nrab yog Kev phom sij. Thiab koj lub npe yog Nerd. Yog li, koj puas tseem xav? Ok, ces. Kauj ruam mus rau hauv lub teeb.

Kauj ruam 2: Lithium

Yog tias koj tau ua si nrog roj teeb lithium ua ntej, tej zaum koj yuav paub qhov kev pom zoo. Cov roj teeb lithium muaj lub peev xwm txaus los khaws lub zog rau lub sijhawm ntev. Lawv tuav tus nqi ntau heev. Lawv tuaj yeem rov them dua li tsis muaj leej twg ua lag luam. Tab sis lawv kuj yog qhov txaus ntshai. Zoo heev. Lawv kuj tuaj yeem nrhiav tau dawb. Txawm zoo tshaj. Txog cov roj teeb lithium-ist dawb, sim nug ntawm lub khw hluav taws xob hauv cheeb tsam uas lawv muaj lub thoob ntim khoom siv rov ua dua tshiab. Qee lub sij hawm cov txiv neej tsis ua li cas nrog koj nqa qee lub roj teeb laptop "tuag". Koj xav tau dab tsi nrog lub laptop "tuag" sib ntaus? Zoo, tsis txhob ua rau kuv pib ntawm qhov teeb meem ntawm lub laptop roj teeb, lwm qhov kuv yuav cua hauv Guantanemo Bay. Cia peb hais tias nws suav nrog qee tus neeg los ua rau koj xav tias koj lub laptop roj teeb tuag thaum nws tsis yog. Ntawm lub roj teeb ntawm lub laptop uas kuv tau nqa, tsuas yog 1 ntawm 5 yog qhov tseeb nyob txhua qhov chaw ze ntawm qhov tuag.

Kauj ruam 3: LED

Yog li, kuv muaj lub roj teeb lithium. Tam sim no kuv xav tau qee qhov LED. Darn. Kuv tsuas yog muag tawm kuv cov LED sau los them kuv cov nqi teeb, thiab qhov kev sib tw no tsuas tshwm tawm ntawm qhov tsis pom qhov twg. Kuv pom zoo cov LED los ntawm 3 lab rupee teeb nyem uas kuv tau ua ob xyoos dhau los. Nrog kev pab los ntawm propane torch-heated exacto riam, tshem cov LEDs tsis nyuaj heev. Nws tau siv ntau lub luj tshib roj, kom paub meej. Tab sis hauv kuv lub Roob Dew ua rau muaj kev npau taws heev, kuv tsis tuaj yeem nres yuav qee qhov tshiab.

Kauj Ruam 4: Ua Teeb Pom Kev

Ib qho ntawm cov LED tsis muaj sia nyob ntawm kev phais. Kuv tau khaws nws, txawm li cas los xij, kom siv los ua spacer. Nrog qee cov ntawv xuab zeb, kuv tshem lub rims los ntawm LED kom lawv tuaj yeem ntim tau ua ke tau zoo, nyob hauv tus qauv zoo nkauj. Kuv muab cov tuag LED tso rau hauv nruab nrab. Kuv siv cov kua nplaum kub kub txhawm rau txhawm rau txhua lub LED mus rau qhov nruab nrab LED. Ntawm txhua LED, Kuv taw qhia cov cathode ntawm qhov chaw. Thaum sib sau ua ke, Kuv qhwv qee cov kab xev ntim rau cov khoom siv ib ntus.

Kauj ruam 5: Soldering

Yog li, tam sim no saib cov duab rau qee qhov txheej txheem kev tsim kho - kev nyab xeeb uas tsis paub. Kuv zoo li tsis tuaj yeem sau cov ntawv pic, yog li kuv yuav piav qhia: 1. muab cov cathodes tso ua ke thiab muab xaim hlau 2. dab nrog kub kub thiab npog nrog daim kab xev teflon lossis qee yam insulator uas yuav tsis yaj. Cov ntawv hnyav hnyav lossis daim npav ntsuas yuav ua haujlwm 3. muab ib daim kab xev tooj liab kab xev tso rau hauv qhov chaw 4. muab tshuaj txhuam 15 ohm resistor rau txhua qhov anode, thiab koom nrog lawv txhua qhov ntawm koj lub hauv paus tooj liab daim kab xev. 5. Siv lub xaim txuas mus rau lub ncoo nruab nrab. 6. Tam sim no koj muaj ob lub xov hlau. Ib qho rau cov cathodes ntau, thiab ib qho rau anodes. Cov LED yog txhua qhov sib npaug, nrog 15 ohm resistor ntawm txhua tus.

Kauj Ruam 6: Roj teeb

Tam sim no rov qab mus rau lub roj teeb. Peb yuav ntxiv qhov chaw nres nkoj them rov qab, ua ntej. Tom qab ntawd peb yuav muab cov kab hluav taws xob ua ke. Kuv siv daim duab thiab mosfet los tswj lub zog, tsuas yog vim li cas kuv thiaj tuaj yeem siv qhov hloov me me. Tham txog Rube-Goldberg. Kuv tsis tau muab tso rau hauv ib qho zoo nkauj flashing qauv lossis dimming nta. Nws tig rau, thiab nws mus pw. Saib cov duab kom ntxaws. 1. Tom qab insulating ntug ntawm qhov tsis zoo ntawm lub davhlau ya nyob twg rau saum, Kuv ua tib zoo txiav tawm qhov feem ntau ntawm qhov davhlau ya nyob twg zoo. Vim li cas? kom txuag tau ib lub hli los yog ntev. Yog, tej zaum tsis tsim nyog raug. 2. Kuv ua tib zoo sau rau hauv kev nyuaj siab nrog cov kua nplaum kub, tom qab ntawd kuv ua tib zoo siv tus poj niam SIP header tus pin thiab xaim mus rau qhov seem ntawm lub davhlau ya nyob twg zoo. 3. Kuv ua tib zoo plam tus so ntawm lub header hla tus pin soldered, tom qab ntawd muab ob sab sab nraud tso rau ntawm ntug ntawm qhov tsis zoo lub dav hlau. Ntau ceeb toom pes tsawg zaus kuv tau siv lo lus "ua tib zoo." Yog tias koj siv lub roj teeb luv, lub roj teeb tuaj yeem ua kom sov sai sai rau qhov kub ntawm cov thermite, fusing lub roj teeb rau koj cov tawv nqaij tsuas yog tawg hauv koj lub ntsej muag tsuas yog ob peb milliseconds tom qab, ua rau tsis pom kev tas mus li! Lossis koj yuav pom lub qhov hluav taws me me, hnov me me nyem, lub valve kev nyab xeeb tuaj yeem lossis tsis tuaj yeem ua raws los ntawm kev tso cov kua ntshiab, qhia tias koj nyuam qhuav tua koj lub roj teeb.

Kauj Ruam 7: Circuit thiab muab tso ua ke

Vim tias kuv tau teeb tsa PIC, kuv tsis tau ua cov phiaj xwm. Tab sis kuv yuav qhia koj daim duab, txawm li cas los xij. Cov nti loj yog PIC. Nws yog ib feem ntawm DIP, tab sis nws tau xuab zeb kom nws thiaj li wafer nyias. Cov nti me me yog SOIC n channel mosfet. Kuv tau siv txhua yam uas yog av lossis NC ncaj qha rau lub roj teeb. Lub khawm kuj tau txuas rau lub roj teeb. Zoo, ib nrab ntawm nws yog. Lwm qhov ib nrab yog insulated nrog daim kab xev teflon. pic2: Kuv tau siv dab dab los ntawm cov kua nplaum kub kom ua raws li LED qhov ua tau zoo, tom qab ntawd ua tib zoo muab cov xov hlau txuas. pic3: Feem ntau, ntawm qhov phiaj xwm zoo li no, Kuv tab tom tua rau 50-50 txoj hauv kev kom ua tiav. Kuv zoo li winging nws. Kuv tsis paub tseeb pes tsawg watts cov resistors tuaj yeem tswj tau. Mosfet tsis yog cov cuab yeej siv logic. Yog li ntawd, thiab hais txog. Zoo, Kuv nias lub pob, thiab woot. Ua haujlwm zoo kawg nkaus.

Kauj ruam 8: Ua tiav

Lub teeb pom kev zoo thiab chaw nres nkoj them nyiaj yuav tsum tau muab epoxied rau kev txhawb nqa cov qauv. Cov smd resistors tshwj xeeb yog nquag tawg. Qhov tseem ceeb tshaj, txhua qhov nthuav tawm ntawm lub davhlau ya nyob twg zoo thiab ib qho xaim/txhuas/tus pin txuas nrog nws yuav tsum raug tiv thaiv los ntawm kev sib tsoo luv luv. Yog li kuv tsis tso qhov no tag nrho mus rau cov kua nplaum kub. Kuv siv cov khoom no. Nws hu ua Kneadatite. Nws zoo li ua qauv av nplaum, tab sis nws yog epoxy tiag tiag uas teev hauv 12 teev, lossis yog li ntawd.
