The KickStarter campaign is over, but you can still get an Xminilab, visit the Xminilab Portable webpage for more information.

The Xminilab is the larger version of the Xprotolab. The Xminilab uses a 2.42" OLED Display. 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 Xminilab and Xprotolab (which I call the "XScopes") have 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 audio plugs, and the logic port is going be a 0.1" male pin connector. The video and pictures shown are from a hand made prototype (the final design will look similar to the Xprotolab-Portable).

Xminilab-Portable vs Xprotolab-Portable:

The Xminilab will be in a "landscape" orientation, this is, the connectors will be on the sides of the device, compared to the Xprotolab-Portable, which has the connectors on the top and the bottom. The screen will be a 2.42" OLED, compared to 1.3" on the Xprotolab. On the first production batch, the color of the display will be AMBER (not green as shown on the prototype).

The Xminilab 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.

Funding will allow me to design and create a mold for the enclosure and build the first 500 units, The enclosure's mold cost is about $6000.00. The parts and assembly costs for the first 500 units is about $15,000.00. If I get at least $15.000 from KickStarter, I can get the project started!

Production plan

1st phase - DESIGN (6 - 8 weeks):

  • Electronics: The firmware and schematics are ready. The first few weeks I will be working on the PCB design.
  • Enclosure: Once the PCB is ready, the design of the enclosure can take place, the enclosure design will take about 4 weeks.


2nd phase - PRODUCTION (6 - 8 weeks):

The enclosure's mold and the device production and assembly will be done overseas.

  • Enclosure: Creating the mold and producing the first batch of enclosures will take about 6 weeks.
  • Manufacturing: The PCB assembly will take about 6 weeks. The PCB assembly can occur in parallel with the enclosure. 


3rd phase - SHIPPING (2 weeks):

Shipping of the finished assemblies to my office will take about a week. I will need at least a week to ship out the packages to you.

Risks and challenges

I've learned a lot from my first campaign, The Xprotolab Portable.
Now I know well what are the risks and challenges, and better yet, how to deal with them.

1) Long Lead Times: I already have in stock most of the components needed, and I already placed an order for the OLED displays, which has a very long lead time. I should receive the OLED displays this month.
2) Uncertainty when doing business overseas: I've been lucky to have found reliable manufacturers, and now I understand how to do business with them.

Nevertheless, there are always unexpected roadblocks, but I will wok hard to get this project fulfilled.
