Weekly Roundup – Top Links for the 4th Week of October 2017

Editor’s Note

This week, I had the wonderful problem of having too much material to share in the weekly roundup, but before we get to the material, I want to go over some of the things that are happening on the site.  First, I want to welcome Brent Voltz as a new author to ElectroSchematics.  Brent and I met a few years back when I was traveling to Pennsylvania for a visit.  Expect an introductory blog post here soon.

Next, I want to welcome back Enrico Miglino.  His next two blog posts are on monitoring 3D printer filament usage and creating a small LED ring for DSLR cameras.  These posts will be going live very soon!

Lastly, for those looking for ideas on Halloween projects, we put together a special Halloween report at EEWeb.  While you are there, take a look at their recently redesigned website.

Now onto the Weekly Roundup…


Your Editor (Me of Course) and Alan Hawse of Cypress Semiconductor at the Louisville Mini Maker Faire

This past weekend, my family and I traveled down to the Louisville Mini Maker Faire.  It was a fun event with lots to do for all.  While there I had a chance to meet up with Alan Hawse.  Alan is the Senior VP of Technical Staff Solutions and Software for Cypress Semiconductor.  It was fun to chat about all things PSoC, and as an extra bonus he was giving away PSoC 4 Prototyping Kits (we may be having a giveaway here soon).

Cypress Semiconductor PSoC 6 101 Video Training Series Started

While chatting with Alan, I became aware that the PSoC 6 101 video training classes have started.  This series will take you through using the new, low power, PSoC 6 device.  This specific set of videos will walk you through building a BLE controlled robot arm, though not just any robot arm, but a “rise of the machines” robot arm full of advanced features.  If you are not familiar with the PSoC 101 classes, then I invite you to go and watch not only the new PSoC 6 classes, but the other past classes covering other PSoC devices.  These videos are super helpful and easy to follow.

App Note from Cypress Semiconductor on Using Straingauge Based Load Cells

I am in the process of working on a few concept models for the Boeing sponsored Go Fly contest.  As part of this effort, I need to measure a few load cells for vehicle validation (afterall, I am an aerospace engineer that does electronics).  In my search to find a solution that would be easy to implement with the hardware I have around the house, I came across this app note.  With the reconfigurability of the PSoC devices, it makes doing things like this very easy.

8 Signal Generators Under $100 Compared

Over at our EDN sister site, Michael Dunn is getting ready to put through the paces some cheap, small form factor signal generators.  As he states, “Like many of you, I lust after good test & measurement equipment, but sometimes one’s budget forces compromise. So, I splurged – but only a little – and picked up a couple of signal sources that cover a good chunk of spectrum – from 0 to 4.4 GHz. The good news is, they ain’t half bad.”  Take a look and let us know what you think.

Autodesk EAGLE with SPICE Analysis is now Available

Autodesk announced that SPICE simulation is now available in EAGLE as of version 8.4.  This has been part of a rapid paced effort to add functionality to the EAGLE design package.  This coupled with the integration of 3D models is really bringing modern functionality to the hobbyist.

ST Microelectronics Releases New Chemical Resistant Pressure Sensor for Wearables

I happened to be browsing the pressure sensor selection at ST’s website a week or so back and I noticed this new little pressure sensor.  A few days later, there was an official product announcement.  I am really excited for this device.  It is sealed so that it can operate in water, but it is also chemically resistant to chemicals such as chlorine.  This is no small task as there are a lot of materials that like to break down in chlorine.  It comes in a small LGA package, and has a 24bit output that is internally thermally compensated.  It also has a 16bit temperature sensor output.  With an output data rate up to 75Hz, this is one of the fastest devices in its class.

ST Microelectronics Power Shield New ULPMark Reference Platform

This power measuring device brings low power measurements to any lab with its low cost and feature richness.  If you need to do some power benchmarking of your designs, this can help you do so with ease.  It can be used in a standalone mode or with the graphical interface found in the STM32CubeMonitor-Power tool.

LimeSDR Launches the LSM8001 Companion Board

This companion board increases the frequency coverage of all LimeSDR products to cover up to 10GHz.  As one would expect from any Lime Micro product, the device is highly configurable and easy to use.  They have posted a video of them implementing a 5.5GHz repeater to personal LTE network capable of streaming video calls with this device.
