FM Tuner TEA5767

Sudah lama kepengen banget buat FM radio yang terkendali komputer istilah kerenya digital. Sudah banyak baca sana - sini sebenarnya sudah lama saya menemukan tuner TEA5767, cuma kok rada gimana gitu kalau tinggal pakai, kurang ada gregetnya. Rencana sebelumnya membuat sendiri dengan memakai tuner copotan dari radio mobil tapi rada susah carinya. Setelah saya pikir - pikir ribet juga belum nanti buat PLL, dsb. 

Akhirnya......

Saya beli tuner TEA5767 ..hahaha 
Saya beli di jualarduino.com seharga Rp. 40.000 saja, kebetulan tokonya ada di Jogja, langsung saya samperin. Lokasinya belakang GOR UNY, bisa dicari di Google Maps ada.

Langsung saya coba malam harinya, mulai pukul 10 malam sampai 4 pagi sampai panas ini kepala I2Cnya tidak terdeteksi :(

Saya khawatir karena ada yang bilang pakai tegangan 5V ada yang bilang pakai 3.3V. Jadi panik jangan - jangan chipnya terbakar gara - gara tegangan terlalu besar. 
Semua kabel sudah saya cek dan masih sudah tidak terdeteksi juga, dan saya memutuskan untuk tidur mungkin memang sudah tidak fokus.

Akhirnya hari berikutnya memulai kembali menyelidiki kesalahan - kesalahan yang mungkin terjadi, dan akhirnya ketemu dengan kabel yang putus ditengah -______-
Kabel yang menghubungkan I2C dengan Arduino ternyata putus ditengah. Akhirnya terdeteksi sudah di alamat 0x60.

TEA5767 testing
Langkah selanjutnya adalah mencoba tuning radio, awalnya memang cuma kresek - kresek suara static listrik, ternyata harus memakai amplifier untuk mendengarkan. Frekuensinya pun dapat dikontrol dengan menggunakan komputer. 


Saya puas dengan chip ini, sudah ada dukungan suara stereo, dan sensitivitasnya tidak kalah dengan radio digital Sony ICF SW35 saya. Nantinya akan saya kembangkan lagi semoga jadi peluang bisnis :)

HackRF Mayhem Failed to Update - M0 Guru Meditation Hard

I was on Mayhem Portapack v2.0.1 and want to upgrade to the latest stable release v2.1.0. The update went okay using the web upgrade https://hackrf.app/. But then I saw the latest nightly update and want to try it, since it has many new tools that are not yet included in the stable release. But then the update failed :( Disclaimer: I didn't take any photos of the errors, since I was focused on googling the solution. So the error was " Bad Firmware or Failed W/R error" during the upgrade process, and it was stuck. So I had to restart the device, and it was booting to the Mayhem menu, but on the bottom left, which should show the current firmware version, it was showing a  "FLASH ERR"  message. I think I should go back to the stable release, but I can't. Every time I want to flash the stable release version, the portapack will shows an error M0 Guru Meditation - Hard Fault.  There's an issue that was closed on the Mayhem GIT repo that has the same issue a...

Macintosh Classic II Brightness Issue

The Problem My Macintosh Classic II suffers from an issue where the display CRT goes dim after a few minutes on a cold boot. Every time it happens, I need to crank up the cut-off and brightness  pot behind the machine to show the image. The Analyze At first, I thought it must be the brightness issue, so I searched for the Macintosh Classic analog board schematic to check the brightness line. I found the schematic from Bomarc, and the schematic is suitable with my board, since there are two analog board versions.  I started to suspect the resistors and potentiometer on the brightness line. This Macintosh version has software-controlled brightness, so the analog board will get a 22.25 kHz square wave PBM signal from the logic board to control the brightness. I checked and replaced some resistors and cleaned the potentiometer, but nothing seems to work. The signal is there, and no sign of degradation that makes the screen dim after a few minutes.  Brightness Line So I suspec...

Fiberhome HG6145D2 Superadmin Login

Maybe some of you are using In**ehome ISP as your home internet and found out that using the provided login has minimal options to configure the router: user  user1234 I know it’s not the admin login, and that must be a full-control user account that can be used to control this router fully. So I searched and found some posts on the net and most of them are telling me to use: admin %0|F?H@f!berhO3e I tested it and it doesn’t work! But there’s more to it, you need to reset the router first by pressing the reset button on the side of the router. Then after resetting, you can log in using the admin superaccount! But keep in mind, never use the user log in again, because it will lock the super admin login until you reset the router again. Cheers 🍺
