Regulator untuk menyolder besi pada Atmega8

Radio amatir adalah hobi saya, jadi tidak ada pekerjaan tetap. Biasanya Anda harus mengeluarkan semua dermaga dari lemari setiap kali, meletakkannya di atas meja atau di lantai, dan kemudian membersihkannya setiap waktu. Pada saat yang sama, outlet di zona kerja biasanya sama, membuat kabel ekstensi selalu malas, dan juga perlu disimpan di suatu tempat. Dan dengan satu outlet mengganggu dengan menguji perangkat yang didukung oleh outlet, sekali lagi tunggu sekitar 5 menit sampai besi solder memanas. Setelah membaca Internet saya memutuskan bahwa saya memerlukan stasiun solder, tetapi menghabiskan 5-10 TR Demi hobi dia belum siap. Solusinya adalah stasiun pemadam darurat.
Siapa yang peduli dengan apa yang terjadi - saya minta kucing.


Pertama-tama, saya membeli

besi solder untuk ali di sini seharga 250 rubel. Besi solder begitu-begitu tetapi untuk rumah itu akan berfungsi, saya benar-benar harus segera mengganti sengatannya, karena sekarang mereka memiliki pilihan masing-masing 100 rubel.
Catu daya dibeli siap untuk 60W 24 volt.

Skema lagi tidak akan, tetapi pada meterai menandatangani semua denominasi.

Papan format awam

Tujuannya adalah untuk menyatukan semuanya dalam satu papan dan sekompak mungkin. Stabilizer daya dan fieldman dipasang berbohong. Perangkat ini didukung oleh 5 volt dan, ternyata, 7805 memanas hingga 70-80 derajat, menempatkan radiator kecil, tiang medan tidak memanas sama sekali.

Saya membuat papan LUT, ternyata hampir sempurna:
Sebelum etsa:

Dan setelah perakitan:

Majelis regulator yang sudah jadi terlihat lebih cantik menurut saya

Jika konektor untuk programmer tidak diinstal, maka board tanpa jumper tunggal.
Seperti Anda dapat melihat detail minimum, bahkan resistor minimum, hanya pada output indikator umum.
Indikator merah dengan jumlah besar, kontrol encoder (valcoder).
Inklusi pertama: Saya

menolak PID klasik, membuat kemiripan dengannya, tujuannya adalah waktu pemanasan minimum.
Jika Anda menekan poros enkoder dan tahan selama 3 detik, Anda dapat menyesuaikan mode tampilan, langkah pengaturan dan koreksi suhu (termokopel semuanya berbeda).
Saya merekam video di telepon, kualitasnya tidak terlalu, tetapi prinsip operasinya jelas


Kasing, kasing ... dan kemudian sebuah pemikiran besar lahir

Dan ketika tiba saatnya untuk memasukkannya ke dalam lemari:
