104 pre amp mic modul

Project 104 in Januari 2019 initiated. but until this time, on May I open this project..
sorry early this year i got busy..  so this is may in 2019 lets go  "Cuusss...."

i open DIY universal Board from PCBWAY nyamm.. yummy fresh from box.

HOw to order ?

Login with youraccount click order quote. I ussualy do fast fill form just fill dimension with 99 length and width 99mm check box use HASL. color green if you want change into blue red or green. purple is expensive, white and black only for closed hardware. they cannot easy read track on pcb. all white or all black

TFT LCD test

TFT LCD test
Using Adafruit 2.8" TFT Breakout Board Pinout
TFT size is 240x320
Unknown LCD driver chip: 5408
If using the Adafruit 2.8" TFT Arduino shield, the line:
  #define USE_ADAFRUIT_SHIELD_PINOUT
should appear in the library header (Adafruit_TFT.h).
If using the breakout board, it should NOT be #defined!
Also if using the breakout, double-check that all wiring
matches the tutorial.

51 arduino io toolbox shield

i need simple shield to demontrate  led r g b

i need to see wave form...  use a0 as input signal

void setup() {
  // initialize the serial communication:
  Serial.begin(9600);
}

void loop() {
  // send the value of analog input 0:
  Serial.println(analogRead(A0));
  // wait a bit for the analog-to-digital converter
  // to stabilize after the last reading:
  delay(2);
}

Project 43 audio vu meter menggunakan ic 74HC595

Desainnya sederhana saja menggunakan IC 74HC595 shiftregister untuk menyimpan data hasil pembacaan analog to digital conveter yang ada pada ATMEGA328. PCB ini di cetak di pcbway.com. Awalnya aku memesan file desain PCB (di upload) dalam bentuk gerber sekitar tanggal 25 September 2017. Baru bisa dibayar akhir tahun nunggu voucher kupon cetak gratis. Setelah di cetak di PCBWAY lalu di kirim ke aku berikut video unboxingnya

38 Simple Clock use sevseg.h print circuit board on PCBway

here the share project about simple clock : scheme grab from Mr. Rokhmad sragen...

and here the layout i retrace from original one. turn into double layer n make top down .

bug : the light no stable.. different each other.. need ressisor 220ohm between board  wire a b c d e f g



after click share n sell you got preview..

 Order ID: G101596 contents :

41proshield
Universal PCB

The reason packing all off them into one delivery is more cheap on freight/shipping charge. I dont care about the time. take more time to wait all of my project produced but its okay.. i just sit relax while create new design. I just im4jine build runnintext  24x8   in radial view.. cool isn it.?

About The price,. i Always use Special promo Price.. limited in size but its the challenge to create PCB simple and small.  still wanna make order again next month. November Desember liitle bit busy endyear report.

so this time to charity.. i spread this PCB into several friends : such as ekobayu Mr. Rokhmad. Mr.Occi, Mr Heryan umm.. do you wanna taste this PCB board? visit pcbway.com meet my project in section shared project outthere...

 i also help several friends to make purchase order at PCBway. the main problem is language.. so i help him to make an order PCB. Greetings from all friends in Indonesia..

Mr. Bobo
