hey guys/gals,
I finally decided to register on here as well. From my simple search this turned to be quite good resource about electronics, so here I come
.
besides the fun-nature person that I am (kind of), I tend to create cool stuff from time to time, or when I get boored. Electronics was my hobby back in the day, then it faded somewhat, then came back again. So yeah, now I'm about to create another nice project (that can be actually usefull to many people and not only me) - will tell later though.
things that I've created in the past:
- alarm system with motion sensors (analog)
- regulated power supply 2x 0-30VDC 0-2A + 1x5VAC output not regulated (for fun). That I had to convert from a 2x18V 3A diagram and besides the fact that it burned all 4 of my digita voltmeters, it worked as power supply. Turning wires to make the transformer = not fun.
- small car amplifier (4x11W or 2x22W rms)
- digital alarm clock (based on philips 87c750 microcontroller). Goes faster by 30 sec per day .. duhh .. needs small crystal offset.
- some complex trafic lights (with no microcontrollers - was a pain but worked with state machine over GAL22v10 logic chip programmed on VHDL)
- audio compressor/expander
- here's a big one - an air gun: game for 3 people
. What it does is it shoots ping pong balls with compressed air into a targed, and keeps score. You adjust the pressure that you want to shoot with, it builds it and you see the pounds on 2 7-seg indicators, when it's ready it tells you and you can move the guy (pvc pipe) with stepper mottor left or right, and shoot, lol. Oh, you enter your name via keypad on a LCD display where you see all instructions about the game. Has external memory too. Pretty cool, I should post pictures maybe. Based on 8051.
- ah, chipped and reprogrammed my car to work well with the turbo that I put on it so that I can smoke everybody (well most) on the highway, lol. Honda Civic FTW.
.. other stuff that I cant remember at the moment ..
anyways, I'll try not to post too much BS and create traffic for the forum, but hope to meet some cool people as well.
so yey, whats up everybody
