Kidogo : 8 channel USB Digital Signal Injector

Kidogo is 8 channel USB self powered digital signal injector. Kidogo system consists with Signal Editor and USB interface module. Kidogo Player is the Signal Editor of the Kidogo system and it can support up to 512 time slots (each range between 1ms to 1s) with 8 channels.



USB interface of the Kidogo system is based around Microchip’s PIC18F2550 microcontroller and generate 5V CMOS and TTL compatible outputs. Dimensions of current version of Kidogo USB interface is 53mm x 40mm (using standard through-hole components) and this can be reduce into more by using PCB layout based on SMD components.


Kidogo Player is design to work under the Microsoft Windows operating systems and it has following general features:

  • Save waveforms and settings as binary file (KDF file) or export waveform as a text file
  • Playback controls such as “Play to segment”, “Play from segment”, “Step back”, “Step next” and “Clear”
  • Shifting and rotating waveforms
  • Invert, Reset, Clocking and Binary Generator functions
  • Copy and Paste waveforms
  • Mute function to each individual channel
  • Launch without any installation or configuration (design to work as portable Windows application)

Kidogo is an open hardware project. All the project files (including PCB designs, source codes, etc.) are released under the Common Development and Distribution License (CDDL). Latest versions of Kidogo project content are available to download at Kidogo GitHub repository.

can you post a compiled hex file?

Hi KYN, you can download compiled HEX file from https://github.com/downloads/dilshan/Kidogo/kidchip.hex

Beauty. thanks,

ya.. i didn't know where to start with the Pic Source code

but i really want to build one

Thanks a bundle!

This is just the project for my 1st. experience in the world of PIC's. Is it possible to burn the hex file to setup with Kidogo as is with the provided board configuration? Does this require an external programmer?

Very nice project Sir !!
Is it possible to adapt it to atmega8 (or else) ?

Good start of project. Now it's with difficulty usable.
For practical and easy usage it's neeed some little improvements:
-in repeat playback mode PIC not send last column
-add any possibility to table import (copy-paste from Excel, import from stupid csv file [0;1;1;0;], edit *.kdf, ...)
-opening with window size which i closed in past or button "save windows size"
-write somewhere to window name of actual KDF file

FOR smoketester:

You need to use external programmer to program the PIC microcontroller.

FOR Dan:

I am not try this with AVR MCUs because in here in Sri Lanka it is bit difficult to find Atmel MCUs :(

For FEN:

"-in repeat playback mode PIC not send last column" This need to be check. I am never notice it in before.

Thanks for your comments and I'll try to include those features in next release(s).

Hello,
I try to build the injector, but I don't have Delphi compiler. Is there a compiled version of UI Kidogo Player somewhere for download?

Compiled version of Kidogo Player (and all other utilities including compiled firmware files) are available to download at "Download" section of "Kidogo GitHub" site. URL: https://github.com/dilshan/Kidogo/downloads

hello,
Please what could be the problem?
set times do not correspond to reality.

Time offset can be happen due to delay in USB transfers. If you need accurate timing please implement delay routine in MCU. Right now timing is handled by the host terminal.

Due to the GitHub changes the download section files are no longer available.

All the download section files are now available in following location:

CD2003 - yet another simple FM radio receiver

In the last few days, we are looking for some simple FM radio receiver to integrate into one of our ongoing projects. For that, we try several FM radio receiver ICs including TDA7000, CD2003/TA2003/TA8164, CXA1019, and KA22429. Out of all those chips we select CD2003 (or TA2003/TA8164) based receiver for our project because of its simplicity and outstanding performance. Except to CD2003, Sony CXA1019 also perform well but we drop it because of its higher component count. We design our receiver based on Toshiba TA2003 datasheet and later we try TA8164 and CD2003 with the same circuit. Either CD2003 or TA8164 can directly replace TA2003 IC, and as per our observations, TA8164 gives excellent results out of those 3 chips. A prototype version of CD2003 FM radio receiver The PCB design and schematic which we used in our prototype project are available to download at google drive (including pin-outs of crystal filters and inductors ). Except for CD2003 IC, this receiver consist...

Arduino superheterodyne receiver

In this project, we extend the shortwave superheterodyne receiver we developed a few years ago . Like the previous design, this receiver operates on the traditional superheterodyne principle.  In this upgrade, we enhanced the local oscillator with Si5351 clock generator module and Arduino control circuit. Compared to the old design, this new receiver uses an improved version of an intermediate frequency amplifier with 3 I.F transformers. In this new design, we divide this receiver into several blocks, which include, mixer with a detector, a local oscillator, and an I.F amplifier. The I.F amplifier builds into one PCB. The filter stage, mixer, and detector stages place in another PCB. Prototype version of 455kHz I.F amplifier. In this prototype build, the Si5351 clock generator drives using an Arduino Uno board. With the given sketch, the user can tune and switch the shortwave meter bands using a rotary encoder. The supplied sketch support clock generation from 5205kHz (tuner f...

Calculator for audio output transformers

Audio output transformers are heavily used in a vacuum tube and some (older) transistor base audio power amplifiers, but these days output transformer are quite hard to find and expensive item. For homebrew projects, the best option is to construct those transformers by ourselves and this script helps to calculate winding parameters for those transformers. This " AF output transformer calculator " script is written using Python and it works with most of the commonly available Python interpreters . The script is available to download at google drive under the terms of GNU General Public License version 3.0 . Homebrewed 25k: 4 output transformer Once supplied the input parameters this script provides a winding ratio, the number of turns required for primary and secondary winding and required copper wire gauges for both primary and secondary windings, etc. We construct several AF output transformers based on results of this script, which including transformers for M...
