This project makes a Vintage MP3 Boombox with a few simple steps. By using an inexpensive Bluetooth MP3 player this old Candle Model JTR1296 Boombox can now be used to crank out some MP3 tunes direct from your smart phone. The boombox is a 12 volt DC player which can get power from D cell batteries, a 12 volt DC input jack or wall power (which is rectified using
This Car Horn Alarm Clock is sure to wake you up in the morning. Not sure if the volume would beat my Fire Alarm Bell Alarm Clock but either is sure to get the job done. The clock in this hack has a nice small motor that is activated to ring the alarm on the stock unit. A small transistor is used to drive a mosfet to handle the
This project allows you to automate the filling of water containers. In this case the need was to stop filling a horse water tank and automatically stop when it has been filled. A few stainless steel clamps are used to sense the water by conduction. The circuit is running off a 9 volt battery, it is powerful enough to activate the 12 volt relay and a voltage divider is
Looking to kickstart your prototyping? JIGMOD might be just what you need. You still get to use your speedy breadboard but those devices that just don’t quite fit can now be a compact module that is held securely over to the side. Moving your prototype around from place to place will no longer be a stressful time since with this system it is much more likely to survive. “How
John Schuch does a Solar Security Light Teardown, the device is to be used in his HackaDay Prize Entry. It often makes sense hacking an off the shelf product instead of designing and building your own especially when the device needs to last in the outdoor elements. John has seen first hand what happens to unprotected powered electronics when exposed even for a short time to the elements on his
Pax Instruments Inc is making an open source temperature datalogger. Charles made a great video going over the entire current prototype showing off the tech inside and reasoning behind many of the build and design decisions. The device is using a MCP3424 A/D, it has 18 bits of resolution so your measurements should be nice and accurate. There is also a lot of thermal management that has been done
Have a master lock that you forgot the combination to? Samy Kamkar shows us how to get in with a nice little motorized combo lock cracking device “Combo Breaker is a motorized, battery powered, 3D printed, Arduino-based combination lock cracking device. It is portable, open source, 3D models provided, and exploits a new technique I’ve discovered for cracking combination locks in 8 attempts or less, but in an even
