I will post a link on my Twitter, and on my Google+ when the show begins.

Less than 48 hours to go!!!

With your help we reached our goal. But we are not over yet! We are trying to reach the $50,000 stretch goal. Please spread the word!

The Original Xprotolab
The Original Xprotolab

The Xprotolab is a combination of three electronic instruments: a mixed signal oscilloscope, an arbitrary waveform generator, and a protocol sniffer. The Xprotolab was awarded as one of the 100 Hot Products of 2011, by the EDN magazine. The Xprotolab has been featured in several other online magazines, such as Hack a Day. and Elektor.

The Xprotolab has been in development for several years, the hardware and firmware are stable. Now its time to put the device in an enclosure and add a rechargeable battery. The input connectors are going to be 3.5mm stereo audio plugs, and the logic port is going be a 0.1" male pin connector. The pictures below are from a hand made prototype.

The Xprotolab is small in size, small in price, but giant in features. You will find most (or more) features of a professional scope:

Features

· Mixed Signal Oscilloscope: Simultaneous sampling of 2 analog and 8 digital signals.
· Arbitrary Waveform Generator with advanced sweep options on all the wave parameters.
· Protocol Sniffer: SPI, I2C, UART
· Advanced Triggering System: Normal / Single / Auto / Free, with many trigger modes; adjustable trigger level, and ability to view signals prior to the trigger.
· Meter Mode: VDC, VPP and Frequency readout.
· XY Mode: For plotting Lissajous figures, V/I curves or checking the phase difference between two waveforms.
· Spectrum Analyzer with different windowing options and selectable vertical log and IQ visualization.
· Channel Math: add, multiply, invert, and average.
· Horizontal and Vertical Cursors with automatic waveform measurements, and waveform references.

I will be using a 600mAh Lipo battery (providing about 12 hours of use per charge) and a Hammond enclosure, the enclosure is big enough to allow a bigger display, I will use a 1.3" OLED. OLED provides very fast refresh rates and high contrast.

The funding will allow to build the first batch of devices in quantity.

Update: I'll include a 10:1 probe to the $100 reward.
Update: Add $5 to your pledge to get the custom curve tracer probe, even if we don't reach the $50k goal.

Risks and challenges Learn about accountability on Kickstarter

There is risk on going thru multiple iterations for the final PCB and the enclosure's overlay. This could add additional delays for the final product. Each iteration adds about 3 weeks of delay.

Another risk is the sourcing of the Lipo battery, which will probably come from overseas. To overcome this risk, there are US distributors available, although more expensive,

The risk on the system itself is minimal, since the hardware and firmware are already stable.
