Light emited in December

2009-12-04T13:36:00.002+07:00

Hooii... Fun in december, how do you do ? Create something shine. In this town, electricity become bad. cause rain, dark in some spot, perhaps the transformer need adjust in rainy day season. First I bought A litte Emergency Light made from battery and several LED white. cool i think.. i love LED revolution product. Many kind of them have sophicated design, very cool i think. Just use LED light now. Next step in End of year we celebrate with many Light in night. Create some LED decoraton, you can create "OPEN sign" from red LED with Blue LED as Border. come on, make yourself one then give me your best shot Picture of your HomeStore or WareHouse. i wait for your best electronic design in your blog. I will give you opinion. please leave your blog link in here as comment. Best regards from tropical nation in here.
thanks you verymuch.

Hello reader, I ask Apologize that i rarely post something here, i get e-mail from Histats, that no new visitor arround here, it means that my page is not good. Then the goal i must make this area not too quietly. Start to make some new stuff. Look back over my shoulder, there are no post about electronic, where am I ? First, i'm too busy with my adminitration job at office, Second honesty i'm lazy to fill story here. sorry. What can I do now?.. hmm.. look arround many broken electronic toys from my nephew. They can re-use for something usefull or back alive again. (but many fraction, crack, and damage plastic body,..) he loves mini train. with round track. soo many hotweel cars collection (several gone). any idea what gift for him ?

2009-09-09T16:31:00.002+07:00

Just wanna write cool day, this is 2009 September 09th, u can write 090909 nice number.
today i have wierd feeling, i had many accident today, splash ink on my hand. Engine trouble on city bus. I friend make mistake and got angry from our bos. well just like that, long time no write here, what am i doing? still dreaming about digital clock. I wish i can make one unit and i put to my office. I seen on tv many digital clock near bedroom. minibox with light of sevensegmen display.

Independent day

2009-08-17T07:03:00.002+07:00

Our Nation celebreate Independent Day at 17 August, What a fenomena, about late of '90 There are something new idea to put bulb light 220 Volt sequentialy at Line. Vertical line with colorfull bulblight, put at your fences. I did take pic that day. You can imagine the power comsumtion about 5 Watt multiply 20 pcs equal 100 Watt. bright enough to glow your home. I plan to make it flickering with simply relay and IC 555 Timer. Until now, the dream does not come true :-(. Anyone can provide me the scheme circuit of that?

Auto Light

2009-07-17T11:01:00.002+07:00

Here my own story, i bought auto light controller, Simple work, "off" at day, "on" at night. You must set switch turn on so that device will work 24 hours. Just plug and add to your socket of ordinary light bulb. Now my home will goes on, even i come home latelty caouse busy hour and work overtime.

budget plan

2009-02-01T10:10:00.003+07:00

Do my Hobby, need some money, yes, i work at local office. goodnews, i got montly salary, but i have limited budget to build my hobby, mostly 10 USD (or 100rb 1 USD=10rb) not more than that. so can you give me information about the cheapest sparepart ? from DSA page i found the price of PIC 16f84 is 35rb and AT8051 15rb, hmm... i don't want mailed sparepart. cause i only one bought one, homebrew, i do it myself. I prefer go to local store here. Surabaya city. you can see the price at Delta electronic shop.

Var Pattern Matrix LED8x8

2009-02-01T10:00:00.002+07:00

Visit www.Dharmanitech.com lately i found and interest project. Microproccesor, before do that i must understand how the memory work dan microcontroller programming. there are many project about matrix LED, Display Variable Pattern via 8x8 LED Matrix. Controlled by microchip PIC, ATMEL, etc.
my plan is creating an used EEPROM to display 8x8 LED, use multiplexer counter to represent 8 coloums. bob blick did that. i want make it too.

VGA to TV

2009-02-01T08:36:00.005+07:00

I have and old PC, Pentium Zero.. hihihi.. i usualy called intel 80486 like that. run on 100Mhz compare with my laptop core is 1GHZ !!! wow far away!

My VGA monitor are blown out. i need cable converter between my PC and Television. Where i can find Paulo sergio VGA2TV Driver ? googling of course. Here Mainteain by Tomy Engdahl's site. the cheap configure are grayscale vga2tv.
becarefull it's will blow your vgacard if wrong soldering.
i did . :-p one my old vga isa card .

Volume Control 4066

2009-02-01T07:54:00.004+07:00

Replace than old mono Variable Resistor with digital one. yes i wish i can create an digital Volume COntrol. i bought IC 4060 it's Quad Switch. use R2R Ladder to make some Bridge. For example the level is 0000 binary (all switch off) the output are 0% when all switch on (1111 binary) then the output 100%. We need some Count Up and Count DOwn IC to produce 0000..1111 binary counter. Use 40xx family IC, can use in wide voltage 3,6,12V. the PCB must not over 3x3cm (two IC) with two button, 4 LED binarycode id.

Can you figure out? What about that scheme? come on quick design it, create it and get the photo. put on your web site . then notice me on comment page :-)

Shining Star LED

2009-02-01T07:45:00.003+07:00

Here I dedicated to my fan. How make a shining star. This scheme suitable for electro beginner, when i teen-age, a create some running, chasing 10 LED use IC 4017. it's work. and i become actdictated. next project are bicycle LED, Horse LED ( a horse? yes, feet, head, tail made from LED, wired together, lovely put on my desk).

The design of star LED is each feet (5 or 6) can light sequentially. need more than one IC 4017, or you just link in series or 5 LED. need TR to pull more power (20mA x 5 LED) better if you use Blue LED, but it's more expensive than green LED. (double price)
not yet to take pic, how about your design?

MicroController

2009-02-01T06:25:00.004+07:00

What is MicroController, that is a small circuit that contains Processor, EEPROM, and Connection between That device with computer. It's much fun if you can controlled it act with downloaded code into it. so this section i will talk about microcontroller, There are many microcontroller, ATMEL 89c51, PIC 16F84, which one ? i think ATMEL cause the price more cheap than PIC, how about u ?

Electronic Digital

2009-01-25T17:38:00.002+07:00

Digital Electronic is start knowledge to get more complexity about how this computer work. begin from lesson How to convert DEC, HEX, BIN, numeric. Lesson two must understand gates :-) OR, AND, NAND, NOR, also how to make circuit. Use several digital IC 74xx TTL and 40xx CMOS, Karnough Map, Add, Sub, multiply, How about Flip Flop, Register, Counter running. Talk about PROM and EPROM, RAM, minimum system consist of Processor and Memory, Know how DAC ADC, I/O, finally you make your own MicroController.
i think i wll start making ring counter project, easy to build use IC 4017 :-)

EPROM

2009-01-25T17:35:00.002+07:00

EPROM = Eraseable Program ReadOnly Memory.
it is IC that can keep data or program instructions.
I use it for first step movement to undestanding about mikroproccessor.
according to DavisSetyaAtmadja from here scheme Paralel EPROM programmer complete Picture i will make that, i hope it's working..

PACMAN STORY, MOVIE?

2009-01-24T07:47:00.003+07:00

imagine, try to live in different age era?.. ice age?.. future space? how to enter that? just try write some story, perhaps it can be movie. can anyone re-produce my story? yes. i wish i can get charity money from this story. :-) bellow is the story one, read it.

my story about Mr. Pacman, yes..you know that is ghosteater or monstereater at old pc. shapebody like ball, bumping, jumping, rolling, sliding, bouncing, spinning, running. plus two hand, two feets, he is yellow, sister are pink, and the cool bro are blue. you can produce toys like this, pop up the handfeet like turtle. dislike? just trow it and crack it become several pieces. yes ask your parrent to buy it again. :-) if exist. hmm whatever, he some kind like carnivora, wide mouth, just hunt and eat. scary is'nt? well i'm not trying tell scary story. only invisible green pacman between the leafplant.

the story began from pacman child era, what? child era? like human-life i guest. story began about his-life, just simple little home, with mom and dad brother and sis. the message is how to to learn in range era chlid to be a man (adult pac-man i means) i tell in era 90'an when he has own pc, (remain me on young era. happy happy forever.) you can sell the laptop or personal computer staton system from this point.
and add google search or any social electronic contents. :-p advertise isn it?
somehow, he become eater all of things, all from rice, vegeta, fruit, chicken,all he loves. also milk from cow :-), go ahead hug and kisses the cow, she is your second mother :-D. little pacman is like monster !!!, more evil than dog or tiger, hmm scary enough. but he try want be good man, not evil naughty bitchy man like other pacman.

in other village have dissaster (its old classic fiction story, u can guest enemy has come) in the realworld, someone eat someone, in pac world, big one eat little/weak things, cruel. you can imagine, pacman has wide mouth, walk sliding, like no gravity. bumping arround 3D X,Y,Z direction, like bubblesoap in the air (he life in unkouwn planet..perhaps poolball :D ) they plan comedown to the ballcity,.. with his troppers jumping like kangoroo, chaos.! darkscreen for a while...

other side story, Pacman got train with his father ( almost good family must do that..) try walk fast like father. soon we battle with that enemies. before they attack our city. try stronger than father, until, you can beat your fatherself :-) but in friendly compettion. the father become old,. yes new generation rise up. you pacman.! give honor, give brightcolor. pacjunior become pacman..!! have ablitiy to : able run faster, chase small creatures...eat it.? have power to blast something (cool like video games) example like fireball, or bowlingball. have secret powerfull weapon, after eat delicious and nutrifous fruit at jungle. (in try and error, he also got poisonus fruit that have sick several days) ask your father first this is poisonus fruit or not.learing by doing.

the funny thing, is pacman try to eat another fruit color beside yellow, than? he become sick. well if sick where we go? meet the Mr. whity pacmaball doctor.!! with grey nurses (don't affraid its not monster she good people) and brighties creamy sexy nursepacwowman (wow..) so the first thep, get in bath, wash the color, the pacman healty and back at his yellow color this is good for learn cymk color. beauty magenta sis has eat cyanida ups i means cyan fruit. and she become blue. (cyan+mag=blue) yellow+mag=red, very hot temperature, pacman eat cyan one? cyan+yellow=green, pacman like drunken master.. do not eat little cyan marbles again. grey pacman eat all of them, then? he become dark. black and death. poor grey pacman. becarefull of what your eat. after eat brush your teeth and tongue. the scene is most lovely fun with tropical rainforrest jungle, warmth, damp, and sweat. not only on mazebox, i dont like prisoned rat, be wild rat, can visit outta the the nation island. afrika, europa, india, asia, amerika. hijjack the overseas ship. how about you? yes visit our beach, bali island, java island, sumatra island, kalimantan, sulawesi, maluku, irian, we have lot of island to visit. Come to Indonesia archipelago. eat the spicies food, extreme food, wierd food, any food can found here, eat like monster. try also visit bromo mountain, kelud mountain at east java. the most complete destination. walk around, feel the atmosphere, deep breath, burned your skin.ups.. back to story..

in bright sunny day, starting the combat, the war were began, wake up young pacman
the monster come to yours village, time to defence. you know they evil thing all weak old pacman, killed, cause not enough power to fight anymore. you the hot one. try to get yourfreedom, all younger pacman get battle (like multiplayers pacman?) well the invasion began, try to defence your land. and yes, you win !!. hurray !!!! now collect more power, to kickback his kingdom moster that always creates new ones.
the bad news, that weak monsters runaway and get charges at his nesthome. and they
come back with full power, never extinct so the decicion is we must destroy the nest.
slay them up to the nest. go ahead, attack..!!!move on !! at the high mountain !

pacman also can weak, to reveal his power he must eat the fruit, (not eat the monster !!) vegeta, get vitamis from there, (it teach child will want eat vegeta and fruit.)
just put in boliled hot water and eat it. i wish pacman become orange :-D
his friends help with bring the fruit from farm,.. yes! green pacman is farmer..! we need him. drink renjuvation recipe: boil water with burning wood branch, add sugar tree, ginger root,coconut. the pac kid also like various battle, various weapon, level and stages. able to climb up.! as usually ending stories, pacman and his friends has nest destroy, yes together is more fun. win the final battle, against the several bigs monsters. destroy the nest. huray again !!! celebrate the double win.!!! after war, life is more peacefull. story end at peace seasion.

i hope this can be cinematic electronic or anime movie. fit in 60minutes video cd. or divX cd. may be i will create in flash animated shockmovie, can u in 3D blender? sorry unable to do that. hello waltdisney ? Pixar ? paramount picture? 20centuryfox? please make my dream come true. that all or my own designed storyboard about pacman, how about u ?

Refer to BillBowden design i interest to build that cute LED Clock, In my new rent home don't have big clock too see, i only see the number of time in southeast corner of my laptop or my handphone.
Prepare for shopping...

i imagine my design like this :

Aviva DIrectory

End of the year 2008

2008-12-01T06:51:00.002+07:00

OKey starting get vacation, even my money not much. Sky in the snw mountain? hei i'm living in tropical area, so, better if i go to rain forest mountain, and make camp at there.
get connected to the mother nature :-) if don't then just with my bro n my sis at backyard. tell our story, eat together. and laydown, read book, play audiosystem loudly. it's sound simply activity.

Every home have own PC

2008-12-01T06:49:00.001+07:00

This Century most home have Radio reviever and Television is almost that true, but how many student college have own komputer to hug ? Base on story on tv Dr. Dogie Howser that everynight write his diary on his PC, cool, and dark envir, feel quietly and peace, before we sleep. After I saw that, then i sleep too.

In the monday morning, I think about what is important to have own PC (Personal Computer) ? well sound like advertise :-) lets go buy Personal Computer, ask one to your Parrent or Uncle. You can write more, listen music while reading blog or..watch the movie. All in One entertainment box, dawn until night.

if you (I) don't have printer well no problem just run to your school or go to near cafe net to get your script print out. Usually I need it to type paperwork at school. but in here not many teenage have own PC cause his/her parrent not rich. Don't be sad, cause we still use at school lab or courses near home. I pray for you will get one printer :-) happy writing. more if you can, get scanner, so movin your script write by hand your old photo, anythink put into your lovely box of PC.

anyway, congratulation if now you get on connected. with electronic mail, homepage, you can make own story on net. tell to the all people in this virtual world, no need to see face of them so not to be affraid. Evil man is every where, in home (is that your bro? :-p) or in your school (bad boy/girl) or at street. In this virtual world (internet) where every million komputer get connected each other. perhaps you connected with bad boy's komputer. so? get virusses from him, stealing your private info, ask too much from you. be carefull, u can think what kind deffense to face that.

if you komputer broken/sick just bring into computer services. or learn yourself to cure it. I play with my computer since 1993, I learn internet since 1998 until 2008. hmm one decade long enough to feel the evolution of computer. being small, being cheap, being fast.

Review Delta Electronic site

2008-11-27T21:29:00.003+07:00

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

2008-11-19T18:44:00.004+07:00

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

2008-11-18T06:18:00.004+07:00

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

2008-11-17T07:26:00.008+07:00

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

2008-11-16T21:08:00.003+07:00

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

2008-11-15T20:08:00.003+07:00

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

2008-11-15T19:44:00.006+07:00

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

2008-11-15T15:00:00.002+07:00

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?

2008-11-10T12:39:00.000+07:00

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

2008-11-07T07:37:00.002+07:00

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

2008-11-05T21:38:00.001+07:00

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.
