			<content:encoded><![CDATA[<div class='snap_preview'><br /><p>ATmega is one of most  popular microcontroller of the world, this is the reason why I use it. For your Information I use :</p>
<p>Operating System :  Ubuntu Hardy</p>
<p>software programmer : avrdude</p>
<p>hardware programmer :  usbasp</p>
<p>microcontroller : AVR-ATmega8L-8PU, ATmega8-16PU</p>
<p>fuse programmer : avrfuse 1.0.1</p>
<p><strong>Fusing</strong></p>
<p>For some reason, such as to<em> booster </em>its performance, we change the fuse setting.</p>
<p>Becarefull!!! &#8230;&#8230;Jancok I&#8217;m not kidding you!!   You maybe make your ATmega8 useless if you set with wrong fuse.</p>
<p>For information, there is the default fuse setting for a brand new ATmega8-16PU</p>
<div id="attachment_220" class="wp-caption aligncenter" style="width: 310px"><a rel="attachment wp-att-220" href="http://nastelroy.wordpress.com/2009/10/03/fixing-wrong-fuse-atmega8/fuse/"><img class="size-medium wp-image-220" title="default_fuse" src="http://nastelroy.files.wordpress.com/2009/10/fuse.jpg?w=300&#038;h=202" alt="default_fuse" width="300" height="202" /></a><p class="wp-caption-text">default_fuse</p></div>
<p><span id="more-219"></span><br />
I often use  16 MHz external Crystal Oscilator for my Atmega, so I set it to :</p>
<p style="text-align:center;">
<div id="attachment_221" class="wp-caption aligncenter" style="width: 310px"><a rel="attachment wp-att-221" href="http://nastelroy.wordpress.com/2009/10/03/fixing-wrong-fuse-atmega8/fuse16/"><img class="size-medium wp-image-221 " title="fuse16Mhz" src="http://nastelroy.files.wordpress.com/2009/10/fuse16.jpg?w=300&#038;h=200" alt="fuse 16 MHz" width="300" height="200" /></a><p class="wp-caption-text">fuse 16 MHz</p></div>
<p><strong>Wrong Fusing</strong></p>
<p>If you make a wrong fuse setting, your ATmega will not responding.</p>
<p>This  is  error log  after I set a wrong fuse, I can&#8217;t flash or my ATmega not respond anymore  :</p>
<div id="attachment_222" class="wp-caption aligncenter" style="width: 310px"><a rel="attachment wp-att-222" href="http://nastelroy.wordpress.com/2009/10/03/fixing-wrong-fuse-atmega8/errorm8/"><img class="size-medium wp-image-222" title="errorm8" src="http://nastelroy.files.wordpress.com/2009/10/errorm8.jpg?w=300&#038;h=208" alt="error" width="300" height="208" /></a><p class="wp-caption-text">error</p></div>
<p><strong>Calm Down!!!</strong></p>
<p>Don&#8217;t throw your ATmega to the trash!!, your ATmega8 is still Ok.  There is some explanation about this problem :</p>
<ul>
<li>ATmega or mikrocontroler must has clock/pulse/signal  to working. I guess it lost its clocks after you setting a wrong fuse.</li>
<li>You Must  give Him external clock (not from crystal that usually connected to XTAL1 and XTAL2)</li>
</ul>
<p><strong>You should do</strong></p>
<p>I have some experience to make ATmega come live again, there is a lot of way to make ATmega come alive again :</p>
<p><strong> 1.  With STK 500,</strong> I will it post later</p>
<p><strong>2. With R &#8211; C </strong>combination, I usually fail with this method, I don&#8217;t know why, but I will post it.</p>
<p><strong>3. With Signal / Pulse Generator</strong>, <em><strong>I never fail with this method</strong></em>.  There is the step :</p>
<ul>
<li>Pray</li>
<li>Connect port XTAL1 (pin9) and GND (pin8) to SIgnal generator set to about 1 MHz.</li>
<li>Bingo!! Jancok!! Hore !! He still alive (but don&#8217;t remove the signal from signal generator)</li>
<li> Set the fuse setting to default. I use avrfuse 1.0.1</li>
<li>disconnect the signal generator</li>
<li>try with none signal from signal generator&#8230;&#8230;Case closed</li>
<li>Alhamdulillah&#8230;Thanks God</li>
</ul>

			<content:encoded><![CDATA[<div class='snap_preview'><br /><p>Sebagai catatan bagi saya sendiri, atau untuk orang lain juga boleh:</p>
<p>Hari ini mau ngeprint tapi drivernya Canon IP1980 buat Ubuntu 8.04 ternyata belum tersedia. Setelah brosing sana-sini, akhirnya dapat juga. Di donwload <a href="http://software.canon-europe.com/products/0010647.asp">nang kene. </a></p>
<p>Akan teteapi setelah berhasil mendownload dan menginstall nya, ternyata printer itu masih kelap-kelip aja, ndak mau ngeprint. Ee ternyata harus di reset dahulu, saya kopi langsung aja ya dari sumbernya (dari forum <a href="http://forum.brawijaya.ac.id/index.php?action=vthread&amp;forum=5&amp;topic=2729">brawijaya</a>), Monggo:<br />
1. Lepas kabel POWER dan USB.<br />
2. TEKAN+TAHAN tombol POWER<br />
3. Pasang lagi kabel POWER (tombol power jangan di lepas)<br />
5. Tekan tombol resume 2 kali<br />
4. Lepas tekanan tombol POWER.<br />

			<content:encoded><![CDATA[<div class='snap_preview'><br /><p>sekedar tahu aja, bahwa  20 mikron = 0.020 milimeter</p>
<p>Setelah berpusing-pusing ria mengkalibrasi CNC, akhirnya belum selesai juga&#8230;loh kok&#8230;UNtuk semua komponen sudah jadi semua, tinggal di kalibrasi satu-persatu. Ternyata susah sekali untuk mendapatkan setelan dengan kepresisian 20 mikron, ada banyak sekali hambatan dan rintangan, antara lain :</p>
<ul>
<li>Machining dari Bawani engineering yang <em><strong>sedikit</strong></em> meleset.</li>
<li>Kurangnya antisipasi atas penggantian bahan dari 15mm ke 18mm &#8211; 20mm, yang mengakibatkan beberapa lubang menjadi kurang pas</li>
<p><span id="more-182"></span></p>
<li>Banyaknya sumbu-sumbu yang harus di sejajarkan dan ditegakluruskan&#8230;ini menyebabkan harus ddicarinya cara yang paling tepat dalam mengkalibrasi CNC tersebut</li>
<li>Belum sistematis, ada beberapa bagian yang harus diubah kedepannya</li>
</ul>
<p>Berikut ini beberapa langkah selama meng-kalibrasi (belum selesai)<strong> </strong></p>
<p><strong>1. </strong><strong>Pondasi</strong></p>
<ul>
<li>ratakan dulu dudukan liner (salah satu) sampai benar2 rata, miring gak masalah, asal tak bergelombang2.</li>
<li>pasang liner pertama, liner ini sebagai master</li>
<li>ratakan dudukan liner kedua, sampai kepresisian 20 mikron (dengan liner master sebagai acuan)</li>
<li>pasang liner kedua</li>
<li>setel kepresisian sejajar dan level, untuk POndasi, saya dapatkan kesejajaran = 20 mikron dan level = 30 mikron</li>
</ul>
<p><strong>2. Sumbu Y</strong></p>
<ul>
<li>ratakan dudukan liner yang bawah(paling dekat dengan pondasi) sampai benar2 rata dan tidak bergelombang</li>
<li>pasang lah liner di dudukan ini tadi. jangan terlalu kencang</li>
<li>pasang base sumbu Y di dudukannya&#8230;</li>
<li>kalibrasi lah liner master tadi dengan acuan level dari 2 liner pondasi, setel sampai benar2 lurus</li>
<li>lepas lagi base sumbu Y, biar mudah dalam mengkalibrasi liner selanjutnya</li>
<li>ratakan dudukan liner kedua dengan acuan liner master sumbu Y, sampai mempunyai kerataan 20 mikron</li>
<li>pasang liner, sejajarkan dengan liner master sampai tingkat kesejajarannya 20 mikron</li>
<li>untuk sumbu Y ini, saya dapatkan kepresisian sejajar = 30 mikron dan level = 40 mikron</li>
</ul>
<p><strong>3. Sumbu Z</strong></p>
<ul>
<li>sumbu Z kalibrasinya sama dengan Pondasi</li>
</ul>
<p>Apabila semuanya sudah oke, maka waktunya dirakit, yang mana pada tahap ini, untuk mendapatkan kepresisian 20 mikron,  tingkat kesulitannya sangat tinggi. Karena saya sudah melakukannya dan belum berhasil&#8230;nanti saya lanjut lah&#8230;.pusinggg</p>
<p><strong>4. Kalibrasi Sumbu X dan Y (90 derajat)</strong></p>
<p>Kalibrasi ini di dahului dengan memasang meja sumbu Y dengan linear guide, pasang semua baut, kencangkan baut2 yang ada di bawah, lalu lepas 8 baut di linear atas, setel Nut-Balscrew sumbu Z, lalu kencangkan.  Pasang lagi 8 baut linear (bagian atas). lalu kencangkan</p>
<p>Pasang Dial di Meja Sumbu Y, hubungkan dengan Sumbu Z bawah. Setel Pondasi Y agar sejajar dengan level di linear Sumbu X. Kencangkan apabila telah sejajar</p>
<p>Saya dapatkan kesejajaran antara Y dengan X adalah sebesar 40 mikron</p>

<p><strong>f. </strong>Keringkan, dengan hair dryer atau setrika, atau laminator. Jangan terlalu panas, jangan lebih dari 140 derajat celcius.</p>
<p>Saya lebih menyarankan mengeringkan dengan laminator, karena pengeringan dan tekanannya lebih merata.</p>

<p><strong>2. Proses Exposure/ penyinaran</strong></p>
<p>Ada beberapa langkah, antara lain  adalah :</p>
<p><strong>a. </strong>Pembuatan Artwork (film)</p>
<p>Artwork adalah semacam film atau plastik  buat  OHP yang berisi track-track PCB, fungsinya adalah menutupi track/jalur PCB agar tidak terkena sinar Ultra Violet. Ada beberapa tipe artwork :</p>
<blockquote><p>1. Artwork dengan kertas minyak : Langsung saja menggunakan printer untuk pembuatannya, hasilnya kurang maksimal.</p>
<div id="attachment_143" class="wp-caption aligncenter" style="width: 210px"><a rel="attachment wp-att-143" href="http://nastelroy.wordpress.com/2009/01/21/membuat-pcb-photoresist/artwok_papaer/"><img class="size-full wp-image-143" title="artwok_paper" src="http://nastelroy.files.wordpress.com/2009/01/artwok_papaer.jpg?w=200&#038;h=131" alt="artwork kertas minyak" width="200" height="131" /></a><p class="wp-caption-text">artwork kertas minyak</p></div>
<p>2. Artwork dengan Film (biasa disebut film negatif) :  Biasanya pesan dulu ke tukang foto atau percetakan, hasilnya bagus.</p></blockquote>
<div id="attachment_142" class="wp-caption aligncenter" style="width: 210px"><a rel="attachment wp-att-142" href="http://nastelroy.wordpress.com/2009/01/21/membuat-pcb-photoresist/artworkfilm/"><img class="size-full wp-image-142" title="artworkfilm" src="http://nastelroy.files.wordpress.com/2009/01/artworkfilm.jpg?w=200&#038;h=140" alt="artwork film" width="200" height="140" /></a><p class="wp-caption-text">artwork film</p></div>
<p><strong>b. </strong>Penyinaran / Exposure</p>
<p>Proses ini menggunakan lampu UV, atau bisa juga menggunakan Led UV.  Proses ini sangat kritis, karena hasil dari PCB tergantung dari lama  atau cepatnya proses ini. Posisi artwork dan PCB nya sebagai berikut :</p>
<div id="attachment_144" class="wp-caption aligncenter" style="width: 210px"><a rel="attachment wp-att-144" href="http://nastelroy.wordpress.com/2009/01/21/membuat-pcb-photoresist/penempatan/"><img class="size-full wp-image-144" title="penempatan" src="http://nastelroy.files.wordpress.com/2009/01/penempatan.jpg?w=200&#038;h=101" alt="penempatan artwork 2 layer" width="200" height="101" /></a><p class="wp-caption-text">penempatan artwork 2 layer</p></div>
<p>Penyinaran boleh dilakukan bergantian atas dan bawah, atau lebih baik lagi jika dilakukan secara bersamaan dari atas dan bawah. Perlu diperhatikan adalah waktu penyinaran(tergantung dengan intensitas lampu). Dengan lampu UV led saya, yang paling baik adalah 10-15 menit. Warna dari PCB yang terkena sinar UV akan menjadi UNgu, sedangkan yang tertutup artwork, warnanya tetap hijau agak biru.</p>
<p><strong>c. </strong>Developing / Pengembangan.</p>
<p>Proses ini menggunakan bahan yang disebut NaCO3 dicampur dengan air dengan konsentrasi di sesuaikan dengan datasheet masing-masing dry film photoresist yang di gunakan. Untuk hasil yang maksimal, suhu air jangan terlalu dingin, sebaiknya sekitar 31-35 derajat celcius. Dalam proses developing ini, bagian yang berwarna ungu (yang kena sinar UV) akan tetap tinggal. Sedangkan bagian yang tertutup artwork, akan larut dengan larutan NaCO3. Hasilnya kurang lebih seperti ini.</p>
<div id="attachment_154" class="wp-caption aligncenter" style="width: 235px"><a rel="attachment wp-att-154" href="http://nastelroy.wordpress.com/2009/01/21/membuat-pcb-photoresist/kolon-2/"><img class="size-full wp-image-154" title="kolon" src="http://nastelroy.files.wordpress.com/2009/01/kolon1.jpg?w=225&#038;h=242" alt="hasil" width="225" height="242" /></a><p class="wp-caption-text">hasil</p></div>
<p><strong>d. </strong>Etching</p>
<p>Setelah proses developing selesai sempurna, maka  PCB bisa langsung di etching. Biasanya etching dilakukan dengan menggunakan Ferrit Cholride (FeCl). Namun bisa juga menggunakan Ammonium Persulfate, yaitu dengan komposisi sebagai berikut 75% air ; 12,5% H2O2 dan 12.5% HCl. Proses etching menggunakan Ammonium persulphate lebih cepat dan lebih bersih. Lalu bersihkan dengan air bersih.</p>
<p>Sekian dulu pembuatan PCB menggunakan photoresist.</p>
