Senter LED Zaman Sekarang

Senter zaman sekarang tidak hanya on/off, namun ada mode redup, kedip dan bisa mengirim sinyal SOS. Cocok untuk bahan soal Finite State Machine di kuliah Sistem Digital dan Sistem Mikroporsesor. Switchingnya mestinya pakai transistor jenis MOSFET, bisa jadi bahan di kuliah Elektronika.

Komponen utama di dalamnya sedikit saja

Chargernya juga sederhana

Teka-Teki Matematika Lingkaran Dalam Persegi

Teka-Teki Matematika dari pak Prof. Hendra Gunawan [tautan]

"Diketahui persegi bersisi 1 satuan panjang. Tanpa bantuan geometri analitik, tentukan luas A, B, C, D, dan E. Kurva dari titik sudut kiri atas ke titik sudut kanan bawah merupakan kurva seperempat lingkaran."

Berikut ini hint untuk mengerjakannya

Tahap pertama: mencari titik potong kedua lingkaran , dapat dihutung dari persamaan garis lingkaran.

Baut 1/4 inch alias baut tongsis

Baut ukuran 1/4 inch.
Di Indonesia mur dan baut yang dipakai biasanya pakai ukuran metrik (dalam milimeter), namun khusus untuk peralatan fotografi sudah standarnya menggunakan mur & baut ukuran 1/4 inch dan 3/8 inch. Standar ini adalah standar imperial, bukan metrik. Mencari baut ukuran imperial ini tidak semudah mencari baut metrik.

Berikut ini pemakaian baut pada dudukan kamera digital:
