Although there are plenty of DIY surveillance cameras already out there, MakeUseOf has taken it to the next level with the ability to remotely control its view. This DIY pan and tilt camera uses a Raspberry Pi, an Arduino Uno, a pair of servos, and a USB webcam.

The Pi streams video to a webpage and adds a few buttons to move the camera. Due to the lack of the hardware PWM pins, the servos are controlled by the Arduino that is connected to the Pi. Meanwhile, a Python server handles the web interface and commands.

Sound interesting? Be sure to check out the entire build on MakeUseOf’s page here.

Breaking bad habits can be difficult, but developing better ones isn’t so easy either. Mindful of this, former Project Ara founder Dan Makoski and David Khavari have come up with a smart, Arduino-friendly lamp that combines light, encouraging messages and a personal improvement algorithm to help you inch closer to your goal day by day.

Connect Peak to your smartphone using its configuration app and set up a habit you’d like to master–whether that’s exercising, reading more, learning a new instrument, meditating, or spending quality time with loved ones. Simply touch the lamp and it will then send you a motivational text message. It recommends a step towards your target that you’ve either entered yourself or have chosen at Peak’s suggestion. You can schedule reminders if you need that extra little push as well. Once completed, touch it again or text Peak and it’ll record your progress, celebrating with a burst of light.

What’s even cooler is the fact that Makoski and Khavari were fortunate enough to work with whiz kids (and our friends) Cesare Cacitti and Quin Etnyre. Peak was actually prototyped using the Arduino platform and currently runs on Etnyre’s own Qduino Mini. Its creators are also exploring the idea of opening the lamp up so developers and Makers can hack their own projects. We’ll have to wait and see until the end of its crowdfunding campaign!

Looking to form a better habit? Enjoy mini light shows? Then head over to Peak’s Kickstarter page, where you can learn more about the product, the philosophy and the entire design process.

As its name would suggest, the LittleArm is a mini 3D-printed robot that began as a weekend project. Its creator Gabe Bentz wanted a small arm that was easy to work with, and one that wouldn’t require him to dig deep into his wallet. So, as any Maker would do, he decided to design his own low-cost device.

After showing the LittleArm off, it wasn’t before long that he was approached by some STEM teachers in the area who wondered if the kit was something they could use in their classrooms. Ideally, every student should have one to tinker with, but unfortunately today’s systems tend to be too expensive and quickly loose parts and pieces. This is a problem that LittleArm is looking to solve.

The arm is powered by an Arduino Uno and four identical metal-geared micro servos, while all other mechanical components are 3D-printed. There’s also a modular gripper that’s actuated by a servo along with rigid end-effectors for various tasks. What’s more, a basic GUI enables you to control the arm, its gripper, the speed, as well as use its record function to train the robot to perform a specific task and then watch it play out the sequence.

The entirely open-source gadget comes as a DIY kit that can be purchased or built from scratch. Want one of your own? Check out Bent’z Kickstarter page here, and see the LittleArm in action below (including some of its dance moves).

If you live with your family, a significant other or a few roommates, and you’re looking for a fun prank to drive them nuts, Connor Nishijima has the perfect trick for you: an Arduino cricket. Unlike actual crickets that are relatively consistent with the sounds they make, this one is a far cry from that. Instead, the Maker’s project will chirp for a brief second, and then go into a deep sleep for a random amount of time between three minutes and three hours. As you could imagine, this can make the source of the noise extremely difficult to pinpoint!

Nishijima combined the JeeLib library for reducing current consumption and his new library for 8-bit volume control to bring the insanely annoying “cricket” to life using nothing more than a speaker, a 7800mAh USB battery, and an Arduino. The best part? He estimates that the setup has enough juice to last for months, if not years. In his case, he enclosed the electronics within a box along with some magnets, then placed it in his vent to mess with his buddy.

For the lowest current comsumption with minimal effort, I’ll be using a 16MHz Arduino Pro Micro with a few power-hog components like the power LED desoldered. Unfortunately, the PWM speeds needed for my Volume lib only work well at 16MHz so far, so using 8MHz to conserve power is out.

However, the awesome battery calculator at Oregon Embeddedtells me that at 16mA “awake” current and 200uA “asleep” current (being asleep more than 95% of the time) this should last more than three years. Of course, the battery itself will have some drain involed with it’s circuitry, but even a FOURTH of the estimated battery life still puts us at almost a full year which is good enough for me, and bad enough for my friend.

Those wishing to give this prank a try can check out Nishijima’s videos below, as well as his code on GitHub.

Maker and astronomy enthusiast Görkem Bozkurt has built a GoTo telescope mount-inspired system that points and tracks any object in the sky using its celestial coordinates. The aptly named Star Track sports a 3D-printed structure along with a pair of Arduinos (an Uno and Nano), a gyroscope, an RTC module, two low-cost 5V stepper motors, and a laser pointer.

Many computerized telescopes have a type of telescope mount and related software which can automatically point a telescope to astronomical objects that the user selects. Called GoTo mounts. Like a standard equatorial mount, equatorial GoTo mounts can track the night sky by driving the right-ascension axis. Since laser pointers are a perfect way to point stars, I thought a laser pointer with a GoTo mount would be a perfect tool for locating stars and to track them.

First I had to design a two-axis mount.

1. 360-degree rotating axis for RA
2. A up-down axis for DEC

After aligning the RA axis with the North Celestial Pole, an Arduino connected with an RTC should be able to calculate and track RA with sidereal time. And you can adjust the two axes to the user input from a computer via serial.

But first I had to find a way to precisely point the mount to given degrees. The main idea was to use step motors and give them a specific step to take. But after a few tests that was not totally accurate.

Instead, I used a gyroscope placed on the laser pointer to track the degrees on the two axes, this way I was able to send a command to the step motor to start and stop the movement if necessary.

Intrigued? Bozkurt provides a basic overview of positional astronomy on his project page, along with all of Star Track’s 3D files, code and assembly instructions.

GitHub user Sanni has created a Nintendo cartridge and save game reader shield for the Arduino Mega.

The ROM gets saved to an SD card. You can also read/write save files to the SRAM, display information about the cartridge on a 0.96″ 128X64 OLED LCD, and calculate the checksum of your ROM dump. You control it using the push button–one click moves the selection down, a double-click moves it up, and a long press executes the current menu option.

As the Maker explains, this shield:

  • Reads SNES ROMs and reads/writes save games from and to the SNES cartridge–supported types include: LoRom, HiRom, ExHiRom, SuperFX, SuperFX2, SA1 (can’t write save back to SA1)
  • Read/writes SFC Nintendo Power cartridges
  • Reads N64 ROMs and reads/writes save games (4K/16K EEPROM + SRAM + Flash RAM)
  • Reads/writes N64 Controller Paks and also can test a N64 controller
  • Programs Flash ROMs like 29F016, 29F032, 29F033, 29F1610 and 29L3211 (needs 3.3V)
