Salam kanggo kabeh sing maca bagean "DIY utawa Do It Yourself" ing Habr! Artikel dina iki bakal babagan switch tutul ing chip TTP223 | . Ngalih makaryakke ing nRF52832 mikrokontroler | , modul YJ-17103 karo antena dicithak lan konektor kanggo antena MHF4 external digunakake. Ngalih tutul beroperasi ing baterei CR2430 utawa CR2450. Konsumsi ing mode transmisi ora luwih saka 8 mA, ing mode turu ora luwih saka 6 μA.
Kaya kabeh proyek sadurunge, iki uga minangka proyek Arduino, program kasebut ditulis ing Arduino IDE. Implementasi piranti lunak piranti kasebut adhedhasar protokol Mysensors | , ing Mysensors. Forum komunitas basa Inggris - , forum komunitas basa Rusia -
(Kanggo sing pengin sinau - , , , , | kanggo sing pengin mbantu () ing pangembangan proyek - )
Papan switch tutul dikembangake ing program Deeptrace, njupuk manufaktur sakteruse nggunakake metode Laser Ironing Technology (LUT). Papan kasebut dikembangake kanthi ukuran 60x60mm (panel kaca standar duwe dimensi 80x80mm). Sirkuit kasebut dicithak ing kaca majalah Antena lan ditransfer nganggo wesi Bosch kanthi setelan "Len" (daya maksimal) menyang papan fiberglass foil pindho sisi 1.5mm, 35μm (ora ana liyane).
Etching ditindakake kanthi solusi ferric chloride, sing sadurunge disiapake kanthi proporsi 1.5 sendok teh saben 250 ml banyu anget. Proses njupuk 15 menit.
Pengeboran bolongan kanggo interlayer vias lan kanggo fastening wadhah baterei wis dileksanakake karo DREMEL 3000 mini-bor dipasang ing DREMEL 220 bor ngadeg. . Trimming ing sadawane wates Papan rampung karo mini-bor padha karo DREMEL 0,4 lampiran (Cutting bunder d = 1,1mm). Pruning ditindakake ing respirator.
Tinning saka Papan etched wis rampung nggunakake Rose alloy ing solusi banyu (1 sendok teh asam sitrat crystallized saben 300 ml banyu).
Proses soldering njupuk bab jam, paling wektu ngginakaken soldering kabel (tinned, 0.4 mm ing diameteripun) ing bolongan kanggo interlayer vias.
Papan kasebut dikumbah nganggo pembersih aerosol FLUX OFF.
Desain awak piranti ditindakake ing editor desain dibantu komputer telung dimensi. Ukuran casing 78,5mm x 78,5mm x 12mm.
Model lengkap kasus lan tutup kompartemen baterei disimpen ing format STL, banjur perlu nyiyapake model kasebut kanggo dicithak ing printer SLA (nambah dhukungan, orientasi). Ing tahap iki, ana masalah cilik, amarga area cetak printer SLA rumah tangga cilik. Model kasus piranti ing posisi paling optimal relatif kanggo wektu printing ora pas karo dimensi saka wilayah printing. Nalika nyelehake model ing 45 derajat, uga menehi asil sing nguciwani, bobot dhukungan padha karo bobot model awak. Diputusake kanggo nyithak model kanthi vertikal, nggawe dhukungan ing salah sawijining sisih ngarep, sing wis disepakati sadurunge karo kasunyatan post-processing. Nyetak awak butuh 5 jam kanthi setelan lapisan 50 mikron. Sabanjure, pangolahan ditindakake nggunakake sandpaper sing apik banget (aku ora bakal nulis nomer amarga aku ora ngerti :)). Tutup baterei butuh 40 menit kanggo dicithak.
Panel kaca saka Aliexpress didol kanthi pigura plastik sing wis dipasang, ora ana masalah nalika mbusak pigura kasebut. Aku mbusak panel kaca sawise preheating karo pengering rambut biasa.
Diffuser kanggo lampu latar LED digawe saka tape sisi pindho kanthi adhesive akrilik 3M 9088-200. Kanggo lampu neon ana sawetara bahan sing bisa dipilih, tape adesif Cina lan kertas adesif dipotong dadi kaset saka perusahaan domestik Luminofor. Pilihan digawe kanggo pabrikan domestik; miturut perasaanku, dheweke luwih cerah lan luwih suwe. A kothak kertas karo pigmen neon iki glued ing ndhuwur karo 3M 9088-200 tape pindho sisi.
Kaca kasebut ditempelake ing awak saklar kanthi nggunakake tape sisi ganda kanthi perekat akrilik 3M VHB 4910.
Tutup kasebut dipasang kanthi sekrup M 1,4 X 5 mm.
Biaya piranti kasebut 890 rubel.
Sabanjure teka bagean program. Ana sawetara masalah. Pranyata Kripik sensor TTP223 bisa digunakake kanthi sumber daya 3.3V sing stabil lan ora apik nalika didhukung langsung saka baterei sing wis kosong. Nalika miwiti piranti karo sumber daya watara 2.5v, plus sawise tambahan "drawdown" nalika nggarap presentation Mysensors, TTP223 microcircuit (sanalika sawise kalibrasi) nyebabake gangguan saka MK amarga iku karo pemicu aktif.
Sirkuit catu daya menyang microcircuit diganti (manajemen daya TTP223 karo gpio MK), lemah tambahan diwenehake, lan resistor kanthi resistensi sing luwih dhuwur diganti ing garis sing dipimpin rgb (sing mlaku ing sisih liya papan sensor kapasitif). Iki uga ditambahake menyang piranti lunak: aktivasi daya kanggo microcircuit kapasitif sawise miwiti kerangka Mysensors lan nggarap presentasi. Wektu tundha kanggo kalibrasi otomatis chip TTP223 nalika daya ditrapake wis tikel kaping pindho. Kabeh owah-owahan iki rampung ngilangi masalah iki.
