sample collection

Sample received today from intersil, maxim, keystone, austiaelectronic dan st. Macam dpt QSL card lak...nak cukupkan sebakul.

The famous microcontroller PIC

Paling banyak project PIC menggunakan 16F84A dan 16F628A. Parts ni microchip mcm maleh nak buat je. So kiranya parts ni dah matured. DIYer mula berpindah ke PIC yang lebih besar capacity memorynya mcm 16F887 atau yang future 16F1938 dan 16F1939. Kalau beli dipasaran mungkin 84A dan 628A leh menjangkau Rm30 sebiji. So apa lagi...request je la.

Sample from ONsemi

Onsemi ni generous juga cuma every sample request perlu byr USD20 untuk shipping dan handling fee. Mereka juga mempunyai 4 jenis engineering kit yang boleh direquest. Very good service from ON. Bilangan pieces yang boleh disample bergantung kepada harga..kalau parts tu mahal, boleh request sikit, kalau murah..boleh request sampai 10 pieces. Gambar diatas adalah Bipolar 50A NPN transistor TO3 package.

1000W RF Power transistor

Very expensive RF power transistor. Baru dapat hari ini. Ikut spec 1000w. Cuma leh request 1 pieces. Nak simpan buat stock. Kalau check harga dia di futureelectronics.com menjangkau sehinggan USD570.17....

Speed internet streamyx

Itulah hasil pengujian kelajuan streamyx yang digunakan sekarang. Just ok ler. Kalau nak download mcm-mcm, guna di saltmine yang kelajuannya lebih kurang 5.6Mbps.

Apa yang dibuat bila di base station?

Bila balik keja, memang malas nak g keluar. Lagi2 bila dah ngadap komputer. Inilah keja2 yang dibuat bila ada kat umah.

1. Baca email
2. Request sample
3. Baca facebook
4. Monitor echolink
5. Monitor 10m band.
6. Monitor 2m band local

Gambar kat atas tu adalah gambar diambik ari ni kat saltmine. Kasi mau tukar sama itu gambar blogger profile. Itu olang ada hensem ka? heheeh

LM3876T sample request

Yet another sample from national Semiconductor the audio Power Amplifier Series High-Performance 56W Audio Power Amplifier w/Mute

•	56W continuous average output power into 8
•	100W instantaneous peak output power capability
•	Signal-to-Noise Ratio >= 95 dB(min)
•	An input mute function
•	Output protection from a short to ground or to the supplies via internal current limiting circuitry
•	Output over-voltage protection against transients from inductive loads
•	Supply under-voltage protection, not allowing internal biasing to occur when |VEE| + |VCC| <= 12V, thus eliminating turn-on and turn-off transients
•	11-lead TO-220 package
•	Wide supply range 20V - 94V

National and maxim

The second batch sample from national semicon. Just ordering 5 pcs LM386-N from them. This is for amplify the ISD audio of my student project. The second envelope is from Maxim-ic. Maxim entertaining all sample requests from customer.

Fuhhh...legaa

Alhamdulillah, hari ini telah selamat sampai ke MCMC tanpa ada kesukaran, jem dan sebagainya. Tiba seawal jam 9.30AM di Cyberjaya. Then debaran memuncak bila memasuki dewan..almaklumler first timer. Sudah ramai yang tiba awal dan rakan-rakan semuanya nampak cool. Bila sesi testing...darah gemuruh mula tiba...apapun dah tiba di MCMC, exam ini perlu diteruskan juga. Akhirnya jam 1.40PM apabila result telah dikeluarkan untuk 'receiving session', barulah lega bila melihat nama tersenarai untuk yang LULUS. Debaran seterusnya ialah untuk 'sending session'. Berbekalkan k12 cw keyer, ujian sending dijalankan dengan lancar....bagi rakan2 yang berani dan tekad untuk mendapatkan 9M..teruskan usaha. cherioooo

Kemet capacitors literature

Want to know about Kemet capacitors and product they are offering. Just log on their website and request literature from there. Kemet also offering an SMT engineering kit for those interested to evaluate Kemet capacitor. Mine not arrive yet. Thanks Kemet...

NJR/JRC semiconductor - very difficult to find.

Anybody knows the distributor for NJR component here? A_very_hard_to_find NJR actually arrived to my school mailbox today. 5 components per tube and 5 parts total. Thanks to NJR Singapore for giving me the precious sample..for those interested for making VOX, NJM2072D is the solution.

An email about microchip sample

Sebelum ni cuma boleh request 2 sample sebulan tapi sekarang microchip telah menukar policynya kepada 10 sample request setiap 40 hari....Hidup microchip!!!

p/s - dengarnya Atmel pun Microchip mau beli. Atmel ni agak sukar untuk memberi sample pada end user. Freescale pula, sample request feenya sangat mahal. So mungkin sebab tu PIC Microchip lebih banyak pengguna berbanding pembuat microcontroller yang lain.

===================================================================

Dear Ibrahim Kadri,

Thank you for your interest in Microchip Technology. Currently - Business, Consultant, and University have up to 10 sample orders (2 line items per order and 3 devices per line) every 40 days. If you reach that limit, you will then have to wait 40 days before ordering again..

Best Regards,

Microchip Samples Team

Good day,

I want to ask about sample order limit. I have six order before reaching the limit. What happen if I reach the limit. Is it no more order can be made or I need to wait i.e. 30days before placing new order?

Thanks.

===================================================================

Doakan kejayaanku

2 more days to go. CW exam at MCMC cyberjaya. Minggu ni sangat QRL dengan mengiring student wakil sekolah untuk kejohanan tenis daerah dan juga menyiapkan project 'Smart Restroom' oleh student untuk pertandingan Innovasi Sekolah Asrama Penuh pada hari Khamis ini....masa bila mau training CW...apapun cuti dah ambil untuk hari Rabu ini (8/4/09) untuk exam tersebut. Ada untung balik petang...kalau tak balik pagi :-(.
