Review Delta Electronic site

Hmm.. about this site, with new face, new design.
but e-magazine section still old style.
where can i download magazine on 2007 and 2008 ?
but overall is good. keep working best.
i interest this sites cause use indo lang
well more easy to me to understand electronic.

Home Camera TV

There are many model that can use and install in your home. Example put at top of your ceiling near the door. U can see people arrive when you in bedroom. What the part?
1. TV cam in my place about 150rb
2. Extended video Cable and Repeater if needed
3. Television Box :-) about 500rb

now i want search the splitter when i use 2 or 4 cameras. AnyOne have the circuit?

note: 1rb = 1000rupiah (about 0,1 USD)

What is Analog n DIgital

Analog is signal continously between Vcc until Ground (example range 5Volt..0Volt)
Digital only accept low signal (0 Volts) ang High Signal ( 5 Volt or Vcc)
can u tell me more the different?

Protoboard BreadBoard

Protoboard is need to assembly the part without any heating. just plug the part feet into that hole. also called Breadboard. If you sure that project running then start to put in your stripboard or PrintedcircuitBoard (can u call copper board?)

ReFine MyAudio

I have Audio Amplifier about 32W, uses 16V 3A. If i use Speaker 8 ohm so the power must about P=VI I=V/R I=16/8=2 A P=16*2 =32 W. Am I right ?

Moving Sign LED 5 x 7

How to make Moving Sign LED ?
base on Mr. Blick. Drew Hickmans have idea to cascading 4017.
hmm have 7 x 20 Matrix LEDs, cool.. Where is diagram idea ?
see at his electronic project. Hmm created on 31 March 1998
update 15 December 2007, hmm how about project in 2008 bro ?
next in end of year, i hope i can make propeller Analog Clock LED.

Audio Clip Player 1999

When i googling, i found this old scheme (re-drw for clarity) about audio clip player. it uses IC 555 timer, IC 4040 counter, IC EEPROM 27512, ResistorLadder DAC, and Mini Amplifier with 324 OP AMP to produce audio clip. hmm.. cute, i wish it can put on my bicycle to promo ice cream, bread, etc. Look like ringtone, ups i mean audiotone.

What about the wave data ?
Try to make from 8bit-mono *.wav file, use any audio converter (ex: winamp waveout) to convert from mp3 to wav. THe calculation, if use 8000hz sampling-rate and 64KB ROM so only 65536 byte / 8000 byte = 8 second !!! hmm...enough to say several word. for promo audio clip ?? see more his project at http://www.nishioka.com

how to re-presentate the percent. of duration ?
Use IC 4017.
input clock from A10 then lets the 4017 calculate the duration every 10% (4017 have 10 led or ) after 10 steps (or 8 steps in A11,A12,A13?) i will back to first led.
i Think it's cool behavior act like Knightrider LED.

Digital Clock with Matrix LED

beginwords
Seven Segmen LED versus 5x5 Matrix LED ? hmm
After i made Digital Clock with Seven Segmen LED
i become bored when i saw it, too old fashion.
remind me since 1999 i bought it,
nothing change. Now, below is my dream story...

the idea is using 5x5 LED is more interesting
u can choose Blue and White LED colors. want more?
sure, u need more money. get some first !!!
Here some sample of number formation

O  OOOOO       OOOOO  OOOOO
O  O   O   O   O   O      O
O  O   O       O   O  OOOOO
O  O   O   O   O   O      O
O  OOOOO       OOOOO  OOOOO

can u read it? it's 10:03. Still cannot read?
i think u must increase to 8x8 matrix led.
anyway image that LEDs put in Plastic Tube, Cool...
need buy cheap memory to keep that simple shape.
hmm.. i'm confusing with design 27c512 help me!!!

example input is abcd binarycode :
0000=0, 0001=1, 0010=2, 0011=3, ...
U should get this knowledge from your school
but still need ic4518 counter to complete thatwork
try design like use ic4026 decade decoder counter.
scanning coloums still needed.
to scan 0 1 2 and 3 coloums for Matrix LED
i think... somehow i cannot figure that.

endwords
u only make 3 duplicate of them.
two minuteSegmen and one piece hourSegmen.
10/11 hour use 5 led only to show "1-"
come on make it, put the quote:
"it's gift for yours girlfriend"

add note : u can redesign new fontface..
and rewrite/flash again to that eprom.
here the example i get from youtube:

FAQ:
Q:why U don't use 24c256 serial eprom?
A:Hmm.. Not yet,Perhaps U design it for me.
at this time i still tryhard to findout
which one : A0,A1,A2,GND,SDA,SCL,WP,VCC :-)
i preffer use 27c512 drive with 4040

Q:How to put data in my EEPROM ?
A:u need PC, software, and interface.
someone else, could u help me, how is interface?

Q:What is EEPROM?
A:Electric Eraseable Program ReadOnly Memory.???

Q:where is complete sheme?
A:soon, if i'm not lazy or get it from other planet.

suka dengan elektro ya?

suka banget,..sejak aku mengenal pelajaran fisika listrik smp itu aku sudah mengaggumi fenomena listrik yang bisa menyalakan lampu, menggerakan mainan elektronik, dan bisa mengirim suara penyiar radio lewat gelombang e-magnetik. menguji kesabaran, ketlatenan.dan kreatifitas membentuk barang baru.
hobby elektronika mulai kelas smp selain itu juga olah raga fisik untuk pertumbuhan maka otak juga butuh latihan menganalisa desain skema menjadi layoutpart pcb. tantangannya, buat ukuran pcb tetap kecil, rapi, dan tertata indah. berikut ini contoh desain pcb yang saya sukai. ada punya desain pcb 8x6cm? silahkan hubungi saya nanti akan saya review dan dipajang disini.

hal yang menyenangkan setelah mendengarkan penjelasan teori dari pak guru (dari yang cuman kita bayangkan saja menjadi pembuktian) adalah praktek.buktikan bahwa lampu menyala kalau disetrum. hati hati memegang kabel jangan sampai kena tembaganya nanti kmu kesetrum juga.lakukan simulasi berulang ulang, lakukan eksperimen yang banyak.maka kamu akan dapat pengalaman yang banya pula. dapatkan pengalaman dari ujicoba. selamat bereksperimen

Tone Control Schematic

Hmm.. after walk around at google, search something like that
tone control ! to complete my 60W Power amplifier.
yeah that and old amplifier that my big bro give 2 me
u can visit other electronic scheme at
www.uashem.com

I interest to Moving Sign LED

After reopening my storage, since 96 when in highschool
i discover that i have kit EPROM IC that not finished yet
i'm to see that. hmm.. today i want to reveal that.
i want to make my dream that day come true.
off cource i have enough money now to buy addition spare part.
next step, i start to use google to find schematic..
hmm.. only got from Mr. BobBlik use 24c512 EPROM with
8x8 display matrix led. any scheme make me more confuse
could u give me more cleary number pin of EPROM how to
program with keypad, i dont need serial connection to PC
do not use AT51 microproseccor (may be next year)
cause have limited fund to make that toys :-p
in the night i still try to learn several downloaded file
hmm.. regain knowlegde about electronic, digital, heat solder.
