Electronics

Peb yuav sim qhia cov khoom siv hluav taws xob thiab cov neeg hlau ntawm DIY cov duab qhia ib qib zuj zus. Qhov no yog lub ntiaj teb rau nws tus kheej. Tiag tiag ntau yam hauv ntiaj teb, digital electronics, fais fab, neeg hlau, mechatronics, thiab lwm yam. Ntau daim teb uas muaj ciam teb sib xws.

Tam sim no, rau ib qhov DIY project lossis fudge hauv tsev, nws yuav luag siv qhov khoom siv hluav taws xob yog li peb yuav sim kawm thiab qhia cov khoom siv hluav taws xob.

Peb tab tom tsom mus rau cov haujlwm kawg thiab tsis yog los piav txog cov khoom siv hluav taws xob, txhua yam yuav ua tau zoo heev. Yog tias koj xav ua kom pom tseeb ntawm kev kawm cov khoom siv hluav taws xob saib ntawm cov cov khoom siv hluav taws xob dawb

Kuv vam tias koj yuav txaus siab rau cov ncauj lus li kuv.

Lub tsev USB teeb

Txoj haujlwm no yooj yim npaum li nws tau siv, thiab yuav muaj txiaj ntsig zoo rau txhua tus neeg uas xav tau lub teeb ntxiv ntawm lawv cov PC lossis Laptop. Cov zis hluav taws xob ntawm ib qho chaw nres nkoj USB nws yog 5 [V] thiab 100 [mA], uas tso cai rau peb ua lub zog ntau yam ntawm nws thiab hauv qhov no nws yuav ua li ntawd nrog peb lub teeb hauv tsev. Ua ntej pib, koj yuav tsum ua tib zoo nrog cov kev sib txuas, lawv yuav tsum ua kom zoo thiab muaj peev xwm tiv thaiv zoo, txij li luv Circuit Court tuaj yeem ua rau rhuav tshem cov chaw nres nkoj USB lossis cuam tshuam "lub PC nws tus kheej".

Cov ntsiab lus tsim nyog yog:

  • 1 txiv neej USB ntsaws nrog 4-txoj kab cable ntawm qhov ntev xav tau
  • 1 LED ultra-kaj dawb (tsawg kawg 2000mCd) (piv txwv, DSE Z-3980, 3981, 3982, thiab lwm yam)
  • 1 Yas Yas Fuse Nrog.
  • 1 47 Ω 1 / 4W lossis 1 / 8W resistor
  • Cov rwb thaiv tsev xws li: daim kab xev, spaghetti, silicone, thiab lwm yam.

Txhawm rau pib, thawj qhov yog los txiav tus txiv neej lossis poj niam los ntawm lwm qhov kawg ntawm lub cable thiab tshem tawm cov thaiv sab nraud thaiv sab nraud (Yog tias lub cable muaj txiv neej nyob rau txhua qhov kawg, xav txog qhov ua tau ntawm ob lub teeb). USB cables muaj 4 tus neeg xyuas pib thiab lawv cov haujlwm yog raws li hauv qab no:

Tus Npe Lub Npe Xim Piav Qhia

1 VDC Liab +5 [v]

2 D- Cov Ntaub Ntawv Dawb -

3 D + Cov Ntaub Ntawv Ntsuab +

4 GND Dub Av

Thawj qhov yog los txiav cov dawb thiab ntsuab cable thiab lawv cov rwb thaiv tsev tom ntej, vim lawv tsis tsim nyog rau qhov haujlwm no. Tom qab ntawd peb yuav tshem lub rwb thaiv tsev los ntawm lwm ob txoj hlua (Liab thiab Dub). Peb tseem yuav tshem tawm tag nrho cov ntsiab lus ntxiv los ntawm cov fuse yas dhos, vim txhua yam peb xav tau los ntawm nws yog ob daim ntawm cov yas (Cov hom fuse no muaj nyob rau hauv cov tsheb qub lossis cov khoom siv electromechanical uas tuav zoo npaum li cas tam sim no) thiab peb yuav nthuav dav ib qho ntawm qhov nyob hauv fuse nrog kom phim rau USB cable.

Ib Leeg Txais AM

 Qhov no yog qhov tau txais yooj yim, nrog rau ob peb daim thiab zoo tagnrho rau cov neeg uas xav pib hauv lub ntiaj teb ntawm cov khoom siv hluav taws xob. Lub ntsiab tsim nyog rau nws kev tsim khoom yog cov hauv qab no:

  • Ib qho IN60 diode
  • Ib qho 18 cm ntev ferrite pas nrig
  • High impedance sib pab
  • 100 tsau ruaj khov pF capacitor
  • Ob tug ntxhais hlaws hlais nplej
  • Kav hlau txais xov thiab hauv av  

Txhawm rau pib nrog, lub thawv roj hmab (lossis cov khoom sib xws) tau ua ntev li 17 cm nyob qhov twg cov pas nrig ferrite tuaj yeem swb tau yooj yim, vim tias qhov tau txais no yuav raug kho rau permeability. Cov txheej txheem tooj liab tooj liab ntev li ib nrab ntawm ib millimeter tuab yuav muab qhwv rau ntawm daim npav ntsej muag (Ua txhaum tias, ib tus neeg xyuas pib yas sheathed cable tuaj yeem siv tau, tsuav yog qhov kev ntsuas tshwj xeeb tau hwm). Txhua txhua 8 laps lub insulator tshem tawm ntawm tus neeg xyuas pib thiab ib txoj kev hla zoo yuav tau ua, cov kauj ruam dhau los yog rov ua dua kom txog thaum 80 laps tiav. Kuv pom zoo kom kho qhov kawg ntawm cov kauj nrog cov nplaum xev kom tiv thaiv cov kauj los ntawm kev rhuav tshem thiab muab tso rau ntawm ob txhais ceg ntoo. Txhawm rau kom tiav cov kauj ruam no, 100 pf lub peev xwm yuav tsum muab tso rau qhov sib txuas ntawm qhov kawg ntawm lub kauj, los ntawm qhov twg tus kav hlau txais xov yuav tawm.

Tiav kauj

Cov hauv qab no yog ua kom muaj kev sib txuas ntawm cov diode, lub clamps thiab lub siab lub ntsej muag siab tshaj li lub ntsej muag:

Daim Duab Hluav Taws Xob - Suab Sib Sau

Nco ntsoov tias qhov kev sib txuas yuav tsum tau ua kom ruaj khov li sai tau kom tsis txhob rub tawm ntawm lub pob ntseg los ntawm kev cuam tshuam rau lub Circuit Court. Daim duab kos qhia tau hais tias muaj pob ntseg, uas yuav tsum tau ua rau tus kais (yog tias nws tsis ua haujlwm, siv lub roj teeb hluav ncaig khi nrog xaim thiab faus nws hauv cov av uas muaj dej noo txaus.

Lub kav hlau txais xov, uas nyob ntawm lub kauj, yog qhov tseem ceeb ntawm Circuit Court txij li nws tsis tsuas yog muab lub teeb liab audio, tab sis kuj lub zog tsim nyog rau nws ua haujlwm. Qhov zoo tshaj plaws, tus kav hlau txais xov yuav tsum tau nyob siab li sai tau thiab tias nws yuav tsum ntev heev (txog 15 metres ntev yog tus naj npawb zoo tshaj rau cov ntaub ntawv no) txawm hais tias nws tuaj yeem siv ua, piv txwv li, cov hlau uas feem ntau muab tso rau dai khaub ncaws Cov. Lub kav hlau txais xov me me yuav ua rau tsis zoo txais tos, ua rau lub ntim qis heev ntawm lub siab impedance lub mloog pob ntseg thiab tsuas yog qee qhov chaw nres tsheb muaj zog heev yuav tau hnov. Thaum muaj ib lub kav hlau txais xov uas ntau tshaj 12 metres, nws yog qhov tsim nyog los tso nruab nrab ntawm nws thiab winding lub capacitor ntawm kwv yees li 50 pf.            

Thaum tsis muaj lub siab lub mloog tsis taus lub mloog pob ntseg, lub tshuab hloov suab ua kom tsawg kawg 1000 Ω tuaj yeem tso rau ntawm qhov tseem ceeb thiab 8 Ω ntawm lub theem nrab (txawm hais tias lwm tus hloov hluav taws xob tuaj yeem ua haujlwm zoo, tsuas yog xav sim) Koj kuj tseem tuaj yeem siv lub ntsej muag sib nqus ntawm 500 Ω onwards tab sis qhov no nyuaj dua kom tau txais. Lub voj voos hluav taws xob ua tiav qhia ntawm no rau rooj plaub ntawm kev siv hloov pauv.

Yuav ua li cas thiaj tsim lub tshuab hluav taws xob mini tam sim no

Ntawm no yog lwm qhov tsim muaj ntawm peb cov neeg ua haujlwm sib hlub Jorge Rebolledo. Nws hais txog kev tsim lub tshuab hluav taws xob tam sim no nrog cov seem ntawm a tshuab luam ntawvCov. Peb yuav siv lub lub cev muaj zog thiab cov zog qhov no. Nws yog lub tshuab hluav taws xob me me thiab phau ntawv siv uas yog siv rau cov lus piav qhia hauv cov tsev kawm ntawv lossis piav qhia txog kev ua haujlwm rau menyuam yaus. Thiab raws li daim ntawv thov tiag tiag kom muaj teeb pom kev thaum muaj kev tsaus muag lossis peb mus pw hav zoov lossis cov xwm txheej zoo sib xws. Tab sis nws tsis yog lub tshuab hluav taws xob, tsuas yog nrog cov duab no yog qhov tseeb lawm.

Kev tsim phom Gauss

Ib zaug tus qhov sib txawv ntawm coilgun thiab railgun, hnub no peb tab tom yuav delve me ntsis rau hauv txhim kho lub coilgun lossis gauss phom.

Cov hauv paus pib siv feem ntau yuav muaj qhov coil, projectile, thiab lub zog hluav taws xob. Tab sis cov qauv uas kuv tau pom ib txwm muaj ntau cov khoom siv, uas ua rau cov "khoom ua si" zoo nkauj txaus nyiam.

    • 4 Gauss Phom Tsim Piav qhia kev tsim kho ntawm ib leeg, ntau, portable, thiab cov hluav taws kub ceev. Nws tseem raug piav ntau ntxiv tab sis cov tswv yim tuaj yeem pab peb.
    • Coilgun los ntawm powerlabs Cov hais mav los ntawm PowerLabs qhia peb tias lawv ua lawv coilgun, dhau kev tshaj lij, ntawm no peb saib rau qee yam ntxiv hom tsev ;-)

Qhov sib txawv ntawm coilgun thiab railgun

Kuv npaj ib co lus sau rau txhim tsa phom Gauss, thiab kuv tau pom qhov tsis meej pem uas muaj nyob nruab nrab ntawm ob nqe lus, coilgun (phom gauss) y tsheb ciav hlau (tsheb ciav hlau cov riam phom).

Txawm hais tias ob qho kev xa mus rau cov khoom siv sib nqus, cov ntsiab lus ntawm kev ua haujlwm ntawm lub cev kuj sib txawv.

Thaum kuv xav ib gaus phom los yog lub nrawm nrawm, tib cov duab ntawm geomax cov hlau nplaum thiab cov khoom siv hlau yeej ib txwm tuaj rau hauv siab, thiab kuv xav tias youtube cov yeeb yaj kiab tau zoo ib yam tab sis ntawm txoj kev loj. Xijpeem ntawm no yog kev piav qhia me me.
