Dave attended the Cebit 2014 event in Sydney at Homebush Olympic Park. Here are some highlights.
The EX¹ the worlds first PCB printer. It prints silver conductive ink onto FR4, paper, mylar, or many other types of substrate.

Dave show you how to solder a small 3 axis accelerometer LGA surface mount chip "dead bug" style onto a microcontroller prototyping board. This technique allows you to easily prototype projects using tiny SMD components designed only for reflow soldering.

Part 5 of an interview with Colin Mitchell, the pioneering founder of Talking Electronics magazine.
In this final part he takes us through some old hardware kits, including the TEC-1 and Microcomp computers.

The first of the new regular segment on the EEVblog - Teardown Tuesday.
Dave cracks open the Philips PM6672 1GHz Timer Counter, and more interestingly, the PM9690 10MHz oven stabilised reference crystal oscillator.
Dave yet again debunks Solar (Freaking) Roadways. This time the prototype SolaRoad solar cycleway path installed in Amsterdam in Netherlands.
Dave shows how to go about doing ballpark engineering feasibility calculations for such a project, calculates the expected payback period, and SPOILER, shows why Solar Roadways will never be a viable technology. This time using real measured data from the Netherlands cycleway prototype, and real measured solar insolation data for the Netherlands

Dave dons the lab coat for yet another installment of the Unusual Oscilloscope Phenomenon
Dave debunks the Solar Roadways project that generated over $2.1M on Indiegogo, as well as almost another million dollars in US government funding.
PART 2 HERE: https://www.youtube.com/watch?v=HOZBrHqTJk4
In this video Dave does the solar generation calculations to see if this system is viable from an energy generation viewpoint, and also how much power the LED's might typically consume.
What are the losses in a typical practical system like this?
Are Solar Freakin Roadways feasible?, or just pie-in-the-sky bullshit?
This debunking covers only a couple of the likely dozens of major technical issues with this concept.
The main take-away form this video is that these solar roadways panels will never EVER be economically viable, and the solar payback is simply comical. EVen if they can meet ann the ridiculously high demands on a physical roadway.
Also, no amount of research will EVER make this a viable idea. You can't just take existing solar technology (which is borderline viable at best of times) and put it in the most hostile physical environment possible, least efficient environment possible, and most costly environment possible and expect it to be viable. It won't be viable, ever.
