Thanks to Creative for sending in the Sound Blaster Roar for review. Right out of the box the quality of construction is evident. The feel of the buttons and switches is top notch, it should provide years of trouble free use. It is easy to pair it to your bluetooth compatible phone and get your tunes cranking on the Roar. If you don’t want to play music through your phone you can select one of the many other methods of playback. Pop in a micro SD card with some music will allow you to keep it standalone and play all of your favorite music. If you have a device that just has a headphone jack out like an old iPod that will work using the Aux in jack. The micro USB port can be used to play music from your computer.
The system has 3 active drivers, one is a long through woofer for surprisingly deep base. There are also 2 forward facing speakers for right and left audio, 2 additional passive radiating drivers fire music out of the side grills.
If you have a cell phone that needs a quick charge you can plug it into the full size USB port. The port has a 1 amp rating so it will also charge most tablets.
Need a conference room speaker? The Roar actually does a good job of transmitting the sound from your cell phone to the speaker and transmits the room audio using the built in room mic. The system is obviously doing a good job of canceling out the sound that it is producing in this mode since there is no feedback.
If you are feeling a bit uneasy in your surroundings you can arm the alarm and press the siren button to grab the attention of everyone around.
You can see that there are good and bad qualities to this device. That being said the good far outweigh the bad. If you are looking for a kick ass portable audio player to fill a room with booming sound this device is for you!
Our friend Colin Karpfinger from Punchthrough.com has just completed his latest project. You might remember his last project, it was the LightBlue Bean. The Automated Surf Notifier uses a LightBlue Bean at the heart and interfaces with some colorful LEDs to indicate where the ideal surf waves are located. Using some daisy chainable LEDs mounted behind a poster of the coast make for a great indication method.
“I enjoy seeing technology added to things in a subtle way. With this surf map, when the LEDs are off, you’d never know they are there. This surf map displays the report for the upcoming week, along with tide times, by use of LEDs behind the canvas. The report is pulled from the web by a Python script on my computer, then sent to the artwork over BLE using the Bean’s virtual serial port. Finally the Bean parses the report and displays the LEDs accordingly.”
If you are looking for a DIY meter project have a look at this DIY Component Tester (translated), it tests Transistors, Capacitors, Inductors and Resistors. It is AVR based and is very flexible, in most cases you can just jam in a device and press the button to analyze the device.
“Automatic detection of NPN and PNP transistors, N-and P-channel MOSFETs, diodes, thyristors, inductors, triacs, resistors and capacitors.
Check out this great Binary Wrist Watch. It’s a true watch for the geek since most won’t be able to read it!

“The time setting mode can be entered by holding the left button for two seconds. After that the display is blanked and the time can be set bit by bit by switching through the bits by pressing the left button. If the bit is to be set, the right button has to be held down for one second. The watch automatically enters normal display mode after the last bit has been set (once you’ve gone through all the bits).”
If you are going to be building a MAME cabinet, you should have a look at the Mini MAME Cabinet that Greg Kennedy built for some tips. He built this thing from scratch and kept the costs down, using some older electronics was a great way get some use out of the hardware that might not have had a use otherwise. The hand made cabinet turned out very nice, at a glance you can’t tell that it was home made.
Complete hardware specs for this build:
Do you still cut your lawn by dragging an antiquated gas powered spinning blade back and forth across the grass? If so you might want to build an autoCut. The autoCut is a robotic lawn mower that is powered from LiPo batteries and the brain comprises of a Raspberry Pi. The goal is to have completely autonomous operation but I think an IP camera would also be a great option for the user who would like to drive this around from the comfort of his living room. Like the project? Be sure to skull it on Hackaday.io.

“I have used three voltmeters and mounted them on a wooden plinth with a clear Perspex cover to give the clock an industrial look.
I have modified Alan’s code to run on PICBasic Pro version 3. I have also added the following.
Switched display On and Off (keeping battery backup as per Alan’s design) but also allows me to turn meters Off in full power mode.
Synchronization to my Master Clock every 30 seconds
Synchronized LED & Re-Synch LED
Synchronization On & Off
Transistor meter drivers
Separate hourly Chime Circuit
Pulsed “tick tock” seconds sound.”
