thanks provide us scheme electronic circuits. I want make cheaper, small and humble Audio LED VU Meter. I think that scheme is simple.
I bought IC LM324 only 1500rp (if 1USD=10.000rp so it's 0,15 USD ?)

libur 3 hari

Bener libur tiga hari? sabtu minggu senin !!! ada yang ngga libur, justru malah masuk kerja, seperti jualan di mall, ato pelibut berita. juga dokter jaga. klo staf administrasi bisa jalan jalan neh, tapi ya dibuat tidur aja, capek.. mau cari tambahan penghasilan juga ngga mood, jadi ga ada duit lebih untuk jalan jalan keluar. jadi nikmati aja di rumah. nonton film dari rental dvd sampe puas, lalu masak-msak dan masak. mie rebus pastinya he.he..
