How To Hack An Apple Time Capsule With A Raspberry Pi

Introducing the "Pi Capsule."  It's currently the only Apple Time Capsule you can plug into your TV...,does this make it an Apple TV?  ;-) Ok, ok, let's say you have an old Apple Time Capsule laying around that doesn't work anymore... (there's quite a few of these out there now as the first generation Apple Time Capsules have been dying now for some time due to failed hard drives or power supplies.) Maybe y ...

Getting Temp, Humidity Information with Android Things

Basically, the project will transfer data with DHT11 over wireless through NodeMCU. This transfer will be done by using an AndroidThings as a gateway and light a led by a rule we set. NodeMCU will be Wi-Fi Access Point; start transmitting your IP and port number to network. Save device to system on AP mode, and establish wireless connection. Once the client connection is set; read the frequency of temperatu ...

Website is Down Detector

  If you work in a company that has a website, you know how important it is that the website always be up and running. That's why you constantly see "99.99999% reliability!" all over the fancy server hosting sites. A website can't make money if the system is down, so knowing when that happens and reacting quickly is super important. In this Instructable, we will use the LinkIT ONE board to make an aler ...

Wrist Mount Digital Altimeter

  This project is a simple wrist mount digital altimeter which is a device used to determine altitude. This design uses atmospheric pressure to calculate the altitude of its location. The lower the atmospheric pressure, the higher the altitude. The project is comprised of a microcontroller (MCU), an 84x84 pixel graphic LCD and a barometric pressure sensor. The barometric pressure sensor used in the des ...

Motorcycle custom instrument panel

  Instruments for the GSXR Since the GSXR is now a street fighter the factory gauges won’t do, and I wanted something I could log air/fuel ratios with so I can jet the bike. I went a little overboard making a new dash.   I had a Planar 160×80 EL graphic display that’s been in my parts bin for years that I’ve always wanted to use, and this was perfect. Unfortunately it doesn’t have a controller so ...

Open Badge: The LED Badge

  Badges are amazing things. Better when you make your own. I was about to attend the 1st MakerFest at NID, Ahmedabad and thought of taking something unique to the event. Badge was a great option and suited the maker theme of the event. So, sitting down with a pen and paper i drew what it would look like and came up something that could be retro-fitted to a usual boring office badge and would have a LE ...

Portable GPS Data Logger

I have built a GPS Logger and it works very well to trace the drove route for two years. By the way, the navigation solution computed by GPS receiver itself has an excellent accuracy without DGPS because an intentional offset added by US goverment has been stopped several years ago. The position error seems to be some meters under clear sky. It is a suffcient accuracy to trace the movement of walk. However ...

DIY milliohmmeter

This is an example of a simple and cheap milliohmmeter that can be made by every maker. The core of the circuit are a current source (LT3092) and a current sense (INA225): a costant current flows through the milliohm resistor under test and the voltage at the current sense output gives the value of the resistor (V=R*I). The milliohmmeter can be used as a stand alone instrument by adding a MCU with at least ...

Anti-Drowsiness Alarm

  This reference design is an anti-drowsiness alarm, which aims to keep the drivers alert by disrupting one’s drowse. According to the study by U. S. National Highway Traffic Safety Administration (NHTSA), drowsy driving is the primary contributor of at least 100,000 auto crashes a year. Statistics shows that most crashes caused by drowsy driving occur from midnight to 8:00 am. During these times, a pe ...

Wifi throwie : improved version

A few months ago, Andreas presented a nice version of the "throwie" (a LED packed with a small battery that you can throw & see shining for hours) using an ESP8266 instead of a LED : a "wifi throwie". He could not make it work with button cell batteries (the ESP8266 draws too much current) so he ended using a 3.7 LIPO battery, which is quite bulky as you can see on the following post : http://hackaday.c ...
