EEVblog #1032 Part 1 – John Kenny Keysight Interview

Wed, 10/18/2017 - 01:40

Interview with John Kenny from Keysight
Part 1 of several more to come, released daily, stay tuned!
Patrons and forum supports will get all the videos early.

This one covers the history earlier days of HP, Bill & Dave and their philosophy, early recruitment, the design centres, cash cows, HP-Agilent-Keysight name changes. Keysight vs Danaher/GE business systems, life sciences, Carly Fiorina and renaming Hewlett Packard to HP, the Keysight Black look’n’feel change, the stock market, designing the 34460A and 34401A, system design efficiency, PCB design, FPGA vs ASIC’s, price points, analog vs dsp power supply design, simulation, engineering recruitment,

John Kenny is presently the Technology and Efficiency Manager for the Electronic Instruments and Systems Group. After graduating from Lehigh University in 1978, he started in Hewlett Packard, working in our Modular Power System team, designing modular supplies, and later moved to our Lab and Industrial Power group, where he was involved in Analog, Digital and Firmware design for the next 20 years, involved in the rollout of our many programmable power products. In 2005, he moved into a new role as the Technology Manager for the System Products Group, which covered all of the GP products, including Power Products, DMMs, Function Generators, Counters and Data Acquisition products. He was directly involved in the development of the breadth of the GP products that you see in the Keysigt catalog today, with more on their way. Recently, as part of the reorganization in 2015 as part of the new Keysight, he became responsible for Technology and Efficiency management for most of our non-RF based products, as part of the EISG Center of Excellence, which includes products developed in Japan, Penang, Singapore, Loveland and Budd Lake.

Dave looks at some issues with fanning out tiny 0.4mm pitch BGA packages, via pad and hole size, tenting, breakouts, solder mask expansion etc.
And then compares it with an 1136 pin Xilinx Virtex 5 FPGA with 1mm pitch to show the difference in PCB process technologies needed.

EEVblog #1028 – What’s All This PC/104 Stuff Anyhow?

Sun, 10/01/2017 - 01:43

Forget Arduino & Raspberry Pi being the embedded platform computing standards, PC/104 has reigned supreme for over 25 years and is still THE industrial embedded computing standard.
Dave boots up a 17 year old 80386SX PC-104 board with Disk On Chip flash drive. Well, after a lot of frustration anyway.

eevBLAB #37 – Youtube Copyright Trolls

Thu, 09/28/2017 - 20:29

Dave got hit with seven Copyright Content ID claims for background music used in his video, from a company called Adrev a.k.a “Adrev for Rights Holders”

2ND UPDATE: (From SmartSound)

Thank you very much for bringing this to our attention. We actually do not use AdRev, or any other company, for Content ID, but we do work with them to release incorrect copyright claims. Since all of our music is royalty-free, flagging our own music would be counter-productive for us. These claims do come up for some music in our library that was originally licensed from the original composer on a non-exclusive basis. This music is indeed royalty-free when purchased from us, but the composer may also be selling the music through other methods that are not royalty-free, and YouTube cannot tell the difference, so it flags the video. These claims are quickly released using the methods listed on our website here: http://www.smartsound.com/support/supportFAQ/#RFM_youtube

However, the music tracks that you reference in the video, “Clear Vision” and “Wild Chase”, are actually owned exclusively by SmartSound and should not be in Content ID at all. In fact, these are 2 of the 5 free tracks that are included with our Sonicfire Pro software that anyone can download for free. It seems that someone has taken these tracks and uploaded them to Content ID and claimed them as their own and is now trying to collect revenue. We take this very seriously and are already working to remove the fraudulent claims for these tracks. SmartSound music is 100% licensed to be used on monetized YouTube videos, and even though Content ID will flag first and ask questions later, we have found that AdRev and other similar companies are usually quick to remove the claims when they are incorrect. Disputing the claim through YouTube never seems to get very far, but using the advice from the link above and notifying AdRev directly through the link in our FAQ should resolve the issue in a timely manner.

Again, thank you for bringing this to light. This is a case of someone fraudulently claiming our music as their own, and we will get to the bottom of it immediately. If you have any questions please feel free to let me know.

Best regards,
SmartSound Software, a label of Eins Medien GmbH

P.S. I have also heard from the head of SmartSound. All claims have been released now but I received another 3 new claims overnight. They should get sorted too.
