electronic function generator oscilloscpe

Oscilloscope (DSO2D10) and Function Generator (FY6900)

I bought cheap oscilloscope and function generator fiew months a go. I used it as prototyping filter mostly (low pass filter, high pass filter, band pass filter). eventhough it's cheap, it's enough for my needs. it's a good investment for electronic enthusiast. complete feature and the important things it's affordable.

cm108 interface for APRS and AX.25 connected mode

I experiment with cm108 several months a go. i began design my own pcb(schematic and layout) using my old eaglecad. i used to messing around with microsoldering long time a go, so it's not too difficult to put some jumpers/wiring to soldering it. board is a motherboard to cm108 board…

Arduino nano, ENC28J60 Ethernet shield and 4 channel relay

i have already made this project previuosly using arduino uno, wiznet w5100 ethernet shield and 4 channel relay shield. But using Arduino nano + ENC29J60 lot cheaper. not mention it has smaller size. Once you get this badboy online on your network, you can control every device in your house using your smartphone or any gadget you have(that rely on your coding skill, ofcourse).

let’s the fun begin 🙂

wait, as usual i don’t do lots of talk so here’s the schematic and arduino code.

How To Make A Propeller Clock

Once upon a time, lifes goes on as usual, boring. Until one day my friend showing me a weird clock on youtube. i said “wow, that was awesome!”, “how it works?”, “i should make one!”. Basically, i have experienced on electronic DIY stuffs. i started to figure out on how to make it, lots of information found. so basicaly, propeller clock based on POV (Persistence of vision)

http://en.wikipedia.org/wiki/Persistence_of_vision

The clock’s graph formed by cheating human eyes, one array of leds burst on constant interval/delay in one motor rotation, continuously (in this case divided to 360 degree in one rotation, can be more for higher resolution).

After i’ve found, understand, (and yet still confused on how it works :P). i started making prototypes with existing MCU module (atmega8535), wired to array of 8 leds. it works, and not good!! it’s too heavy, no index reference, the text is very unstable. i need to design new board which is lighter and throw out all unnecessary components. there are two web site that i’m using as references, when building this clock.

i used the codes from there with lots of modification, original code is writen using ICCAVR, i converted it to AVR Studio.

i used his isolated power supply, to power up the propeller clock module.

For remote control, it was stolen from here: 😀
