Cov Lus Qhia no yuav coj koj los ntawm kev sib sau ua ke rau Niftymitter, qhib qhov chaw xa xov tooj cua mini FM. Lub Circuit Court siv tus khiav oscillator pub dawb thiab ua raws Tetsuo Kogawa's Simplest FM transmitter. Qhov haujlwm no muaj nyob ntawm www.openthing.org/products/niftymitter
Kauj Ruam 1: Yam Koj Xav Tau
- Sau Daim Ntawv Teev Npe [.xls]
-
PCB txheej v0.24 [.png]
Cov PCB tau tsim los rau kev kos rau ntawm daim hlau, siv hlau ntawm acetate (xws li tau piav qhia ntawm no) lossis siv Michael Shorter's laser engraving method piav qhia ntawm no [qhia paub]
- Cov duab sib dhos hauv Circuit Court rau etched PCB [.png] Koj kuj tseem yuav xav tau cov cuab yeej hauv qab no: Cov hlau txuas, cov khoom siv thiab cov laug. Hlau snips.
Kauj Ruam 2: Solder ntawm Resistors thiab Capacitors
Muab cov khoom sib dhos tso rau ntawm lub rooj tsavxwm los ntawm saum toj no. Tom qab soldering ob txhais ceg mus rau cov pawm, txiav qhov tshaj. Pib los ntawm soldering tag nrho cov resistors. Ua raws nrog txhua lub capacitors thiab jumper lead. Ua kom ntseeg tau tias lub tshuab hluav taws xob hluav taws xob tau taw qhia raws li tau piav qhia hauv daim duab kab hluav taws xob teeb tsa, sab tsis zoo nyob deb ntawm lub qhov (socket).
Kauj Ruam 3: Cov laug ntawm lub Qhov (Socket), Chev thiab Trimcap
Tom ntej solder ntawm lub qhov (socket). Saib xyuas kom ntseeg tau tias lub qhov (socket) tau khov kho. Solder ntawm lub trimcap, ua tib zoo saib xyuas lub tiaj tiaj raws li qhia. Tom qab ntawd ntxiv cov kauj. Cov lus qhia rau kev ua coils nyob ntawm no.
Kauj Ruam 4: Solder ntawm Transistor
Thaum kawg ntxiv cov transistor, saib xyuas kom taw qhia cov pins kom raug.
Kauj Ruam 5: Ntxiv Kev Sib Txuas Fais Fab
Cov laug ntawm qhov ua tau zoo los ntawm PP3 clip rau +9V. Ntxiv qhov luv luv ntawm xaim mus rau hauv av txuas.
Kauj Ruam 6: Npaj Hloov
Khoov qhov ua tau zoo ntawm qhov hloov LED ib puag ncig ntawm ib sab ntawm tus ncej hloov taw raws li qhia. Siv cov laug thiab txiav cov ceg LED raws li qhia. Khoov hla tus ceg LED uas seem los ua lub voj.
