Project 90 line fllower use nano

cool enough in size 10x10cm. I also order  PCB Linefollower use nano (see another story in microcontroller blog)

here detail package : Order ID: G153704  Order time & date: 4/20/2018
Recieved date : 22  Mei 2018

to celebrate Arduino day.. i this week i spread my PCB to my Friend.. and he is the lucky one.. got 20 design.. because i know he able to understand my design.. he have store that sell arduino parts. enjoy

spectrum Analiser 2017

sorry for long time not report here..   here my story :

past time I Ordered  PCB from PCBway ( G48438 11/4/2016 ) it Is Spectrum analizer board controller, This is my project number 10. (i also ordered universalPCB 4x6cm 10 pcs). i kept them.. eanwhile i ordered many project.. it abandon project for longtime.. until i order project no 22.

Meet the Layout from Mr. Boen Baroe SB. I ask friend (Heryanto)  to build this LED board, 

Order ID: G83162  Order time & date: 6/15/2017 and here the picture (use Gerbv application)

Project no. 22  Displ4y Bo4rd

so I collect thoose PCBS.. still not completed because i must print the filter PCB.. until and the end of year 2017 i ordered the last pieces of three Spectrum analizer project. Thanks to Bebe the designer.
hurayy...  PCB ariived from PCB way..  10 pcs with black shine excelent hard material (fiber)
i have mistake.. the drill is too small for my resistor Ahhhh  ..nevermind.. i search thin ressistor foot. (1/4w)  i nececesary i will drill more thick about 0.5mm

Order ID: G94500 Delivery Address Order time & date: 8/11/2017

SIze board  92.38mm * 100mm  Thanks for PCBway i got special price $5  

i will choose Thickness:1.6 mm, 2 Layers 

but sad news I comp4re  PCB Display Board, PCB controller, and This PCB filter . The problem is
There are header that is not suit4ble pl4ce. how a pitty. try re move yourself.. donload that gerber at PCBway.com.  Well at last, forget the past story, in future my plan next round i will re make with new design revision. I ill be back 8-)

digital clock atmega8

pen4mpil 4 dijit 4  untuk  4udio 4mplifierku

keputusan memilih atmega8 karena punya kelebihan. lebih langsing cantik
karena cuman 28pin   dibanding yg atmega16 lebih gemuk dengan 40pin

keterbatasannya tidak punya pin sebanyak yg 40pin. dibantu oleh ic 74595

dari dua pin out (clock n data) menjadi 8 pin output, untuk mendispplay kode_angka.

ini bisa untuk animasi geser ke atas (fill blank brbrp kali sampe rise up and disappear)

compile and send.. memudahkan dengan arduino. tidak seribet avrstudio. 6pindata plus vcc gnd total 8 pin..   modul segmen menggunakan 74595.  cek use gerbv.exe  OK.

re4dy send to pcbway com

result :

error found... i m4de mist4ke... ooppsss... i did it 494in.  see correction line bellow :

sorry my friend :(

my Gerber File ready lets go to PCBway to create PCB

after redesign my audio display, i need Board more clean. so I go to PCBway to mak an order.

step by step how to order :

1. open the pcbway

pcbway.com

Project no 6 - Audio LedMatrixDisplay 10bar x 8ch

Purpose for audio display... The truth This device scan all ten channel audio mixer.. but due many condition and reason. i shrink into eight channel. able fit into 10x10cm box.

LMD Board shorted from Led Matrix Display. Use ordinary LED diameter 5mm total 80 dots..


Finally  This projects consist 3 stacked PCB.

LedMatrixDisplayBoard,

ControllerBoard and



FilterBoard.

Again, I ask PCBway to print this design. waiting for progress : still need double layer to create clean and cozy surface PCB.   here the design.

Audio Mixer 4ch with Mini Amplifier

i plan creating audio mixer from MIcrophone. in small box about 10cmX8cm. 3 Input and 1 output mini 3,5mm stereo.

Tahun baru 2016 bikin apa ya

selamat tahun baru Hijjriyah 1 Muharram 1437H. Liburan ini gag sempet bikin amplifier. cuman menikmati amplifier ku yang sudah jadi OCL dengan TR FInal tip41 tip42. udah itu saja.. blum ada waktu luang untuk hobbi ini. kerja kantoran dulu buat kebutuhan hidup iihihi..
