Here i will post stuff i have found that no electronics engineer would ever say is junk.

For starters.
Oscilloscopes... they cost a bundle and are usually quite lacking in features.

Behold!!!!
The Xprotolab

This tiny scope has:
Dual trace.
8bit logic analyzer.
Basic Signal generator "awg"
and measurement tools.

It has a pc interface Via micro usb.
And is based on AVR meaning it's easy to program your own firmware thanks to the full open source nature of AVR.

And it's dirt cheap with a tiny size and very low power consumption.

General Specifications:

ATXMEGA32A4 36KB Flash, 4KB SRAM, 1KB EEPROM
Graphic OLED display 0.96", 128x64 pixels
Module size: 1.615" x 1.01"
PDI interface.
4 tactile switches
Micro USB, to use with the UART to USB cable.

Oscilloscope specifications:

2 Analog Inputs
Maximum Sampling rate: 2MSPS
Analog Bandwidth: 200kHz
Resolution: 8bits
Input Impedance: 1MΩ
Buffer size per channel: 256
Input Voltage Range: -14V to +20V

Logic Analyzer specifications:

8 Digital Inputs
Maximum sampling rate: 2MSPS
Protocol Sniffer: UART, I2C, SPI
Internal pull up or pull down.
Buffer size: 256
Voltage level: 3.3V

AWG specifications:

1 Analog Output
Maximum conversion rate: 1MSPS
Analog Bandwidth: 44.1kHz
Resolution: 8bits
Output current > +/- 7mA
Buffer size: 256
Output Voltage: +/- 2V

Dayamn that fucker is TINY!

And yeah 50 bucks for it isn't too bad, although other bigger oscilliscopes with them color screens (BIGGER) are around 200-500 bucks...

Don't let the tiny screen fool you.. it's very powerful.
and very readable.

Oh no, I don't doubt it, and the screen is lookin' crazy bright as well, and looks pretty damn functional.

The fallout one looks classic.
I'm going to make mine look like a tool from Tri-OP.


Also.. open source.. so awesome.
Explains why it all works so well.

Some dude used one to make a heart monitor.

OK.. so you kids want to program chips.
The best way to learn is to procure a Amtel AVR "adruino uno" board.. at $30 it's cheap.

1. no extra tools required.
2. open source
3. the most popular.
4. every one uses 'C' and now you can learn C too. still however ASM and Basic is still supported.
5. easy expandability with a 'shield'

I use ASM for those funky projects that require very accurate timing on a instruction level.
But most well paying companies now use 'C' "i just add my ASM into code 'C' blocks for rendering.

There are many great IDE's for AVR.

Well worth it.
