Improve your programming skills with an oscilloscope

via Arduino Blog

Oscillo-02

Starting a new project is always a fun yet effective way to hone your skills while exploring circuitry and programming. To help improve his engineering chops, Joop Brokking recently bought an inexpensive oscilloscope (a device for visualizing voltage over time in an x-y graph) and connected it to an Arduino Uno. He then shared his findings in a detailed tutorial on YouTube.

In the video below, Brokking is using a Hantek 6022BE 20MHz dual-channel oscilloscope and provides three examples to better understand what can go wrong when building a simple Arduino setup.

Free PCB Sunday: Pick your PCB

via Dangerous Prototypes

BP-600x373

We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few PCBs from one of our past or future projects, or a related prototype. Our PCBs are made through Seeed Studio’s Fusion board service. This week two random commenters will get a coupon code for the free PCB drawer tomorrow morning. Pick your own PCB. You get unlimited free PCBs now – finish one and we’ll send you another! Don’t forget there’s free PCBs three times every week:

Some stuff:

  • Yes, we’ll mail it anywhere in the world!
  • Be sure to use a real e-mail in the address field so we can contact you with the coupon.
  • Limit one PCB per address per month please.
  • Like everything else on this site, PCBs are offered without warranty.
  • PCBs are scrap and have no value, due to limited supply it is not possible to replace a board lost in the post

Name that Ware, October 2016

via Hacking – bunnie's blog

The Ware for October 2016 is shown below:

I like this one because not only is it exquisitely engineered, it’s also aesthetically pleasing.

Sorry for the relative radio silence on the blog — been very heads down the past couple months grinding through several major projects, including my latest book, “The Hardware Hacker”, which is on-track to hit shelves by early December!

App note: SOLERIQ® L38

OSRAM’s filament looking LED application note. Link here (PDF)

SOLERIQ® L38 (GW T3LxF1) is a filament LED with a beam angle of 360deg for indoor retrofit lighting applications. It combines the advantages of modern LED technology with the aesthetics of traditional light bulbs.

The construction of the SOLERIQ® L38 consists of a ceramic based frame with two alloy connectors at both ends. A number of highly efficient LED chips (depending on the lumen package) is mounted on the ceramic based frame and they are electrically connected through wire bonding, covered by a colored diffused silicone resin.
