Electronics and Embedded Programming V2 - Developers

[QUOTE=ROBO_DONUT;32749452]I think you mean charge. Current is flow of (positive) charge.[/QUOTE] It's both. The flowing charge also means that energy is flowing. It takes energy, to create voltage (aka a difference in charge (and charge density), or remove electrons from one point (+) and shove them to another point (-)), which then is stored in the voltage and amount of charge. It's hard to get your mind around it, but once you understand it, you'll see how it is preferrable to use what we call the conventional current flow over the physical flow. [editline]12th October 2011[/editline] Although you'll of course have to think in the physical way when you're observing single electrons moving around in a magnetic or electric field though, which can be quite confusing the first time.

Oh snap, didn't even see this thread when I made [url=http://www.facepunch.com/threads/1131730]this one[/url]. You guys have any opinions?

Is it possible to program an Arduino Ethernet from the SD card or network? I plan on using it in an upcoming project.

Well you can do it using a XBee [url]http://www.faludi.com/itp_coursework/meshnetworking/XBee/XBee_program_Arduino_wireless.html[/url]

Could I be added to the OP list with the TI MSP430 or is that for Arduino only?

[QUOTE=Asgard;32757979]Could I be added to the OP list with the TI MSP430 or is that for Arduino only?[/QUOTE] I don't see why you shouldn't get added. MCU is MCU.

I have an ATTINY2313, and I wanted to write assembly code for it to read/write from the EEPROM. Not using the standard functions, so I could learn how it works. I'm using AVR-GCC. However, when I compile this (This is the middle of the function) I get the error "Number must be positive and less than 8" for any sbi instruction with EECR and EEMPE, or EECR and EEPE. Any fix? [CODE] check: sbic _SFR_IO_ADDR(EECR), _SFR_IO_ADDR(EEPE); rjmp check; out _SFR_IO_ADDR(EEAR), r16; out _SFR_IO_ADDR(EEDR), r17; sbi _SFR_IO_ADDR(EECR), _SFR_IO_ADDR(EEMPE); sbi _SFR_IO_ADDR(EECR), _SFR_IO_ADDR(EEPE); sei; [/CODE] I wanted to stop using my Arduino and begin working plainly with the AVR microprocessors to get more experience, but after making a successful LED blink program, I ran into this error. Edit: Fixed, turns out I'm not supposed to use _SFR_IO_ADDR for bit names, only for registers, messed up there :v:

I don't think I ever posted this, but I got an awesome desk for Electronics! The other desk in my room is cluttered with homework and other stuff!

[QUOTE=Asgard;32474631]The lovely Chryseus put together this list for me: [img]http://i.imgur.com/qzh6Z.png[/img] What do you guys think.[/QUOTE] Some pages ago I´ve posted this. I am currently able to order it but I still can´t press the Checkout button. Is this really a good decision for a noob in electronics?

I mean, I just desoldered some shit from a couple of old rc cars and bought a cheap breadboard at radioshack and I've been fine just for dicking around.

So, is what I am planning to order too much?

[QUOTE=ddrl46;32796251]I see you are a big fan of Adafruit?[/QUOTE] Adafruit is pretty great. They have a bunch of stuff that I can afford. Shipping is mediocre though. I go to radioshack a lot too.

... You do realise Adafruit is very expensive in comparison to other major suppliers ? Radioshack is not that great either. Example: 0.1" header strip (10 pieces) 36 pin Adafruit = $7.50 Bitsbox = $3.15 RS = $4.40 Newark = $4.71

The only things I've gotten from them is my Arduino, a couple breadboards, and a Soldering kit. What I like about RadioShack is that I can drive over there and pick parts up quickly. I don't go there often, but If I need a couple LEDs or resistors It is the fastest and easiest way. Thanks for pointing this out!

[url=http://www.instructables.com/id/8-Pin-Programming-Shield/step14/Get-your-own/]This guy[/url] is giving out a bunch of 8-pin programming shields to people who make an Arduino-related instructable.

Instructables needs to die.

[QUOTE=ROBO_DONUT;32815297]Instructables needs to die.[/QUOTE] It was good before it got all shittied up with the pro membership bullcrap.

Also, for the list on the OP, I also have two MBEDs Its these small things: [img]http://www.antratek.com/images/mbed-lpc1768-250.jpg[/img] One got like 3 pins fried from a faulty motor controller though

Albeit my incredible skills to break stuff, I never fried a pin.

Everything is ordered and on it´s way. Now to think about what to make once I get all the components.

Speaking of frying pins, I just got some bits of protoboard to wire up a pair of relays on. I'm aiming for a pair of outlets that I can control from my microcontrollers, I just need to find a suitable enclosure before I continue. [editline]fakeeditline[/editline] Actually, that gives me an idea for a project to do with my SCRs as well; a serial-controlled 6-outlet dimmer box. I'll have to figure that out at some point, that'd be great for computer-controlled lighting. I bet I fry at least a few components before I get that put together.

Anyone got something fun for me to make once I get my stuff? Should be around Thursday.

[QUOTE=Asgard;32830995]Anyone got something fun for me to make once I get my stuff? Should be around Thursday.[/QUOTE] Blink LEDs in patterns, use PWM to create an LED-candle, use some analog stuff, draw your own potentiometer with a pencil (draw a thick graphite line on paper, then connect one end to + the other end to gnd, and there you have your selfmade potentimeter) I think that should keep you busy (and/or mesmerized) for a few days. [editline]17th October 2011[/editline] Also don't worry if something explodes. It happens to the best of us, and it's a expierience for life.

[QUOTE=ROBO_DONUT;32815297]Instructables needs to die.[/QUOTE] Why?

[QUOTE=Ortzinator;32834199]Why?[/QUOTE] Because the site is pretty awful in general and because they're so relentless about monetization when it's their users who write all the content. It's pretty scummy to exploit a community like that.
