Chad Herbert’s son Daniel was diagnosed with Benign Rolandic Epilepsy in 2014. It’s a type of epilepsy the Epilepsy Foundation says accounts for about 15 percent of all Epilepsies in children and the good news is that most children grow out of it.

The bad news is that Daniel’s most affected by his condition at night or early morning while he sleeps. That’s why Chad invested in a sleep monitor/alarm for his bed that detects when he’s having a full tonic-clonic seizure.

At the same time though, he decided to work on a DIY version of a seizure alarm  running on Arduino Micro. The starting point was Arduino’s “Knock” example project with the sketch code originally created in 2007 by David Cuartielles and modified by Tom Igoe in 2011:

While shopping around for the exact type of monitor/alarm my wife and I wanted, I found out a few things:

  • They are hard to find. I believe the one we ended up with was manufactured by a company in Great Britain.
  • They are expensive. The one we ended up getting cost in the $400-$500 range.
  • The one we have isn’t totally cumbersome, but it’s not easy to pack up and take with you somewhere.

Figuring these things out, I decided to search for a way to build a simple seizure alam that’s both relatively inexpensive and easy to transport. I’m sure there are people out there who have children that suffer from seizures that simply cannot afford equipment such as this even though they truly need it. Thanks to the folks in the Arduino community, I was able to accomplish both things I was setting out to do.

Discover how it was made on his blog.

Recently we have learned how to interface GSM Module with Arduino and send/receive SMS using GSM module. Interfacing any device with a micro controller is the first step to building a useful system or project with that particular device. In this tutorial, we are going to build a very interesting project – a Fire Alarm System which will send SMS to a set of Mobile Numbers when fire occurs in a particular location. We have seen many typical Fire Alarm projects which will alert with a siren or an automatic shutdown mechanism. This fire alarm project make use of modern communication technologies to deal with emergencies.

So, first thing I did was to get the LCD and keypad working together.

For this I pretended that it was some sort of arm/disarm (or entry/exit) thing.

My code for this part is at: http://pastebin.com/YndLneqm.

Getting the LCD wired up was tricky as most wiring diagrams for it don’t show the last two pins wired up and these are required for the back light. Check my snazzy Fritzing wiring diagram to see how I wired up my LCD screen, pot (for adjusting brightness) and keypad. The pins for them all are also mentioned in my code.

Bag movement alarm for theft prevention

In short: I developed a portable, battery powered device that sounds an alarm when your bag or purse is moved. Once armed, can only be turned off by your secret code.

The device is built off an Arduino compatible Trinket Pro, using an off-the-shelf project box with PCB.

Winter is coming. So it is time to make preparations. If you live in a colder climate, you need to be concerned about the possibility of your pipes freezing. There are a lot of preventative measures that you can take such as insulating your pipes and leaving the water dripping. But for a little extra peace of mind, I designed a simple alarm that will notify me if the pipes are getting too cold and are in danger of freezing.
