We are now in a golden age of printed circuit boards. It wasn’t too long ago that making your own circuit boards either involved a lot of money, or slightly less money and using some proprietary garbage PCB layout tool. 394 more words
the Hackaday Community from across Ireland and other parts of Europe poured into the performance hall at Dublin’s Project Arts Centre for a massive collection of talks.
Hackaday is hosting a full conference in Belgrade, Serbia, on 26 May. Today we’re excited to announce the workshops that will take place at Hackaday Belgrade. 419 more words
Look for our Drew Fustini in purple!
Hackaday and Tindie are on the road in the UK and we want you to grab one of your projects and come hang out! We have three meetups scheduled over the coming week
From Bradley Ramsey on the Tindie blog:
Watching your robotic creation take flight is an incredible feeling, but watching it collide with something or crash can make your stomach turn. One common sensor you may reach for in a case like this is the VL53L0. But it only provides ranging to a distance of 2 meters. For many of us, this is just shy of a range we would be comfortable with.
Thankfully, a new sensor has appeared which doubles the range. The VL53L1 extends the accurate distance detection to 4 meters. It also uses a patented ranging technology that harnesses time-of-flight from a 940 nm laser.
This results in estimation independent of surface reflectivity and high accuracy in a variety of weather and environmental conditions. This breakout board sold by Pesky Products is designed to bring out all the best capabilities of the VL53L1 from ST Microelectronics.
AndiceLabs writes about a fixed-wing autopilot project:
The BeagleDrone is fixed-wing autopilot project based on the BeagleBone and the IMU cape. The IMU cape provides a 3-axis magnetometer, accelerometer, gyro and a barometer on the BeagleBone’s I2C bus. There is also an AVR micro on the I2C bus that handles output pulse timing of the 8 servo channels and input pulse timing on the 4 radio signal channels. Two of the BeagleBone’s UARTs are exposed via FTDI-compatible connectors to allow connection of external modules like GPS and telemetry. It also has a regulator that provides 5VDC for the BeagleBone, AVR, and servos from the RC battery.
The BeagleBone provides the power of Linux in a footprint that is acceptable for RC and the Black has now made the platform even more affordable. With Linux’s extensive libraries and utilities almost any feature should be quickly realizable and development enjoyable. And unlike an autopilot powered by an 8 or 16 bit micro-controller, there is no need to worry about code and data size or overloading the processor with whatever crazy navigation features you can dream up.
I enjoy flying electric RC planes whenever I get the chance and building a fixed-wing autopilot for the BeagleBone has been on my list for a while now. Of course, there’s no reason that the BeagleBone couldn’t also control a multi-rotor aircraft. A flying Linux box is going to have very few limitations!

Check out last year for some inspiration:
Dan Maloney on the Hackaday blog:
To fight the shakes, you can do one of two things: remove the human, or improve the human. Unable to justify a pick and place robot for the former, [Tom] opted to build a quick hand support for surface-mount work, and the results are impressive considering it’s built entirely of scrap.
It’s just a three-piece arm with standard butt hinges for joints; mounted so the hinge pins are perpendicular to the work surface and fitted with a horizontal hand rest, it constrains movement to a plane above the PCB. A hole in the hand rest for a small vacuum tip allows [Tom] to pick up a part and place it on the board — he reports that the tackiness of the solder paste is enough to remove the SMD from the tip.
