LED Heart Beats With The Beholder via Hackaday


Many a maker likes to use their craft to create gifts for loved ones. [Jiří Praus] was celebrating having been married for 5 years, and crafted this beautiful LED heart sculpture to commemorate the occasion.

The outer shell was created by first starting with a 3D printed heart shape. This was used as a form upon which the brass wire could be soldered together to form an attractive heart-shaped cage. Inside, an Arduino Nano is hooked up to a series of WS2812b LEDs. The LEDs are flashed in time with the heartbeat of the person holding the heart, thanks to a MAX30102 heartbeat sensor. There’s also a TP4056 charge module and a small lithium battery to provide power for the device. 

Adding the heartbeat sensor really makes this project shine, forming a connection between the holder and the device itself. The tasteful craftsmanship of the brass design makes this an excellent gift, one we’re sure anyone would like to receive. We’ve seen [Jiří Praus] make the most of this artform before too, with projects like this stunning tulip or dead-bug Arduino.

Elsewhere Online: AT&T's Spam Filter Gets A Bit Too Aggressive

This story from TechDirt lays out yet another reason I recommend that folks DON'T use the email provided to them by their ISP. My typical recommendation right now is to get a Gmail account instead. It also points out why I want to manage all my SPAM on my end, without pre-filtering from an ISP. I will gladly manage my spam if it helps to insure that I see as many of my "real" messages as possible. Again, Gmail's tools work pretty good in this regard. Having an alternative email account also insures you will keep the same email, even if you decide to leave your current ISP. Witness all the folks holding onto AOL accounts just to keep their AOL email address. Thank goodness at least that is free now. AT&T's Spam Filter Gets A Bit Too Aggressive You can certainly understand why ISPs offer spam filters. It's a service for users who don't want to be totally bombarded with spam. But what I've never understood is that these ISPs rarely give the us

On my iPhone…IFTTT (If This Then That) for iOS

IFTTT (If This Then That) for iOS IFTTT (If This Then That) for iOS My best description of IFTTT, both their main web site, and this new iOS app is "a scripting language for the We." It allows you to set up "recipes" that watch one particular service, like Feedly, Evernote, Gmail and more, and then take action on another service whenever a particular action occurs. I use this to automatically save my shared items from Feedly and elsewhere into an Evernote Notebook and also use it to post automatically post information on a variety of services. The iOS app adds to this functionality by allowing you to take various actions on your phone and triggering IFTTT actions whenever they occur. In the case of the iPhone, initiating actions can include adding new contacts to your iPhone, taking a new picture and more.  For more complete information on how IFFTT works, visit ifttt.com    From the iTunes App Store...
