In this tutorial Dave explains what a PCB spark gap is and how it can be a useful zero cost addition to your PCB layout to help prevent ESD damage.
He shows how to easily design them into your board and calculate the approximate voltage rating.
And of course has some fun applying 5kV to some gaps to show how them at work.

In this episode Shahriar reviews the new Keithley 2450 Source Measure Unit (SMU). This model, which is the successor to the widely adopted Keithley 2400, offers performance improvements as well as a brand new interface platform with multi-point touch screen.
The review demonstrated the instruments GUI, scripting capabilities through the TSP interface and various performance parameters. Furthermore the scripting features are used to measure super capacitor capacity, the performance of a wireless charging system, characterization of optoelectronic components and semiconductor elements.

Who is the winner of new WIZ550S2E-232 module from Wiznet? In addition to getting to know the winner, you can also watch the video record from webinar…
“Hardwired TCP/IP” instead of a software solution? The result is higher performance and reliability. You could find this out during webinar about Wiznet modules.
From all of those who filled in our questionnaire after webinar we have drawn the winners of WIZ550S2E-232 module. The winners are:
- Rastislav Michalek from Applied Precision s.r.o.
- Roman Kasprzewski from DOMIQ Sp.z o.o.
- Roland Kovacs from Robert Bosch kft.
- Christian Baitz from Harbach
- Martin Šustík from URC Systems
Congratulations to the winners.

Dave plays around with an energy harvesting kit to see how much power he can get out of a Peltier device used as a Seeback effect module to generate power from temperature differentials.
Bonus white board tutorial of how Peltier devices work as heat pumps.

In this video I take a look at the Zener diode used as a voltage reference and the effect of temperature on the stability of the output. (temperature coefficient)
By using a normal silicon diode in series which has a negative temp co you can offset the effect of the Zenner’s positive temp co.

Record attendance and development sets for great prices. Webinar with IQRF about wireless solutions was also about this.
This time, we again realized two webinars during just one day – one in English and one in Czech language.Usually, we draw one winner of development set out of all webinar participants. However this time, all participants had a chance to get DS-START-03 development set for fantastic price.

A very brief look at the new WENS 540 Debug Meter with Charles from Trio Test at the Electronex show stand:
This is NOT a review, or my normal blog content, it’s just a quick look because some people may be interested in it. So please, no silly complaints.
A combination 10MHz oscilloscope, 50000 count meter, 8 channel logic analyser, data logger, serial protocol analyser, and digital pattern generator.
