Spent all day on this.
Debugging hardware is fucked man...
Me proud.
Wanted to make a devrant logo like always (its my Hello world to test my CNCs now).
And.... When I finally had the machine calibrated... The pen stopped working lol.
I'll just continue tomorrow, it's finished...
Probably gonna use a few times and make a bigger one.

!rant
Four hours of work.
You think you write spaghetti code? I write spaghetti wires.
H-Bridge dual motor tester for stepper motors.
Speed is controled by pot.
H-bride are L293D.
My third board, and the first that won't go to the trash.

Question. With the baterry off the motor continues spinning with the 5v from arduino.
My question is, is the L293D suposed to do that? Or do I have a short circuit somewhere that is giving power to the motor? Meaning it can burn the arduino.
Runs a 12v stepper from a CD-Rom driver perfectly at 5v from the arduino and actually starts to act strange when I turn the 12v on. (maby the circuit it's adding 12v + 5v?)

My new toy. RC prototype :-D

Ever saw a open hard drive from the inside?

Hey guys.
Well I've been down last months due to a burn out and medication.
Last ween I finally got my first arduino, then second and two kits...
Now I'm addicted...
Stopped Proscriating with games.
Started learning electronics and shit, specially , started cleaning... And just did my first project :p

New work place (changed the PC bellow (so now I have just a little more room.
And the stuff that arrived in 10 days.
Only arround 90 packages to arrive, all arduino or eletrónics related...
Must up my credit card limit
... Reached maximum this month.
No I only need that energy I had before the brake down.. Maby forcing me to finish the projects I already have in mind.
After all, I need a cnc to make my projects, so I must make one

Hey guys.
So, I have a new printer for parts.
Question, what type of glass does scanner uses? Does it have some special treatment or is it normal glass? Thanks

I'm so happy.
If nothing goes wrong I'm starting a formation on eletrónics, robotics and hardware in the end of the month...
Oh yeah, exactly what I needed right now.

Fuckkkkk.
Do you remember the formation I was going to take? Eletrónics, robotics and computers... It has been delayed again because there isn't enough people....

No one wants a job in the area where the future lies... Stupid, stupid people.

#eletrónics, #power suply
Hey guys, I have a question about power.
I converted a 400w power suply into a power suply for my projects.
With more than 10amps per wire can I use the 5 volts to power stuff like my phone or Will it burn?
Also it gives 5.3v is that a problem?
