Hey, Is This Thing On? A Visual Device-Status Indicator Story

DIY humidifier on active indicator LED assembled frontIt’s winter and the air in my house is dry, humidity at about 30%. That’s too low to be comfortable. I’ve lived in my new place for less than one year so the low winter humidity hadn’t been a problem for me yet. Good thing there’s a whole-house humidifier on the forced-hot-air heating system. I’ll just turn that on, right? Wrong. I don’t think this system had ever worked since it was installed…. Continue reading

Open Garage Door Indicator Light

garage door open indicator comicI admit it, I’ve left my garage door open all night… a few times. Doing so leaves all of my precious spare parts exposed for the taking! And maybe more importantly, provides access to the inside of my house…. not a good situation. I’ve been thinking about making some sort of indicator (inside the main house) for when the garage door is open. This would alert the home owner (me) that the garage is open.

After thinking about it for a while, I believe I came up with the simplest way to do this….

Adding a Second PSU to your Desktop PC

2nd atx psu turn on circuitSome Graphics Cards for desktop PCs require a lot of juice to work, sometimes even more than the PSU Power Supply can output. And if you decide to run dual monitors with dual Graphic Cards, then one Power Supply may not be enough. There are a few options to elevate this situation. Purchasing a new hefty PSU would result in a tidy but expensive solution. A more DIY-friendly and significantly less-expensive solution is to add a second PSU (which you probably have kicking around) and delicate the 2nd PSU to your Graphic Card(s).

There is one tricky part to doing this, the PC motherboard controls when the PSU turns on and off. This post will go over how to automatically turn on/off the 2nd PSU with the PC.

Qi Charging Phone Wasn’t A Failure After All

Qi Wireless Charging Receiver Soldered - Samsung Galaxy Exhilarate SGH-i577A few days ago I posted how my wireless phone charging hack was a failure. I tried soldering in a Qi Receiver into my old school Samsung Galaxy Exhilarte SGH-i577 phone. While I got all the goodies crammed in the phone, the phone got waaaaay hot when charging. So much so that the phone gave a warning saying the battery is over-temp and charging was stopped!

Fast forward a couple days. I figured I could try a different charging pad. Guess what? It worked perfectly and the phone didn’t get hot! I can’t explain it. I’m not a Qi expert but I did poke around on Wikipedia to learn more about the Qi technology. From Wikipedia:

“Regulation of the output voltage is provided by a digital control loop where the power receiver communicates with the power transmitter and requests more or less power.”

DIY Wireless Phone Charging, Works And Doesn’t Work At The Same Time

Qi Wireless Charging Receiver Soldered - Samsung Galaxy Exhilarate SGH-i577 I’ll be the first to admit my phone is old, very old, but it is small and fits in my pocket nicely. Majority of new phones seem to be near-tablet size. I did want an upgrade and I thought wireless charging would be the way to go… here’s my disappointing story:

You’ve most certainly seen those Qi Wireless Charger Receivers that plug into the micro-USB port on a phone and make your phone have wireless charging capability, right? They are only a few bucks on eBay. I bought one knowing it wasn’t what I wanted because it uses the USB port and it required the use of a phone case to keep it from flopping in the breeze. When I received the charger receiver, I also noticed that it would cover up the flash and part of the camera. The charger receiver was too long:

CT Hackerspace proud to become an official Hackster Event Location.

hackster_logo_bluethe-ampersand-hotel-london_monogram CTH_LOGO_BITMAP_CAPTURE

In 2016, Hackster set on new mission: reach 50,000 makers and developers around the world through a physical network of Meetups and Workshops, focused on IoT education in the 21st century.

Hackster.io is an online community for hardware hackers. Are you an electronics newbie that wants to build the next awesome robot? Are you a seasoned pro that has more ideas than time? Are you somewhere in between? Hackster are looking for hackers and makers to share ideas, work on projects, and much more!

Led by a network of passionate ambassadors, they’re giving communities and partners a voice in envisioning what’s next in hardware, the cloud, and connectivity, and the magic that happens when they all come together. Hackster Ambassadors run live events that benefit their communities. Hackster supports them on the national level by providing access to hardware, software and learning materials through corporate partners. Hackster also provides training necessary to build a welcoming community and run stellar events.

Two local technology enthusiasts have teamed up and have been approved as Hackster Ambassadors. Bill Saturno and Louis DiCarro, both involved with cutting edge technologies and also key players in starting individual hackerspaces in Connecticut, are excited to start working with Hackster. They can’t wait to empower local makers and developers on emerging technologies …and they have figured what better place to host these events than CT Hackerspace. CT Hackerspace’s facilities can handle groups of almost any size, and has resources in house needed from a hosting a small group lecture to a full fledged hackathon needing tons of tools and supplies within their 4,000 square foot facility.
