This animated C-3PO replica, made by one of our customers, moves its eyes, arms, head, and—in true C-3PO fashion—tells tasteless jokes. The movements are animated by a Pololu Mini Maestro 18-channel USB servo controller. A Pololu RC switch with relay (controlled by the Maestro, not an RC transmitter) shuts off the power to the head to avoid servo humming noises. (You can achieve a similar result with most servos by not sending RC servo pulses, which a Maestro does when the servo target is zero.)
The customer’s C-3PO web page has more videos and extensive documentation on how the replica was built.
Are you afraid to color outside the lines? Do you cringe at the thought of free-handing your way through a project build? Do you experience an unreasonable amount of solace by having all those unruly components locked down to a PCB while you mutter, “Everything in its place, yes, precious”? Well, grab your fave hand tools, ‘cuz it’s time to step outside your comfort zone. In this episode of ATP, we’re going to take a closer look at point-to-point soldering.
Questions? Concerns? Ideas for the next According to Pete? Accidentally soldered your hands together? Leave it all as best you can in the comments, call a doctor, and we’ll see you next time!
Wanting to see data from their high school’s HAB launch, 9th grader “Spaceshark” and a few of his classmates decided to build their own data tracker.
According to the project’s write-up, Spaceshark’s school has an astronomy club which sends HABs to the edge of space. Although the 360-degree video embedded here would be enough to satisfy most people’s curiosity, this team wanted more data!
Spaceshark’s group proceeded to create a data logger using an Arduino Uno, along with sensors to collect data on the satellite’s latitude and longitude coordinates. Altitude, wind speeds, time, and the satellites in view can also be recorded, saving readings on a microSD card for later analysis.
Matthew “Raspberry Pi Guy” Timmons-Brown puts together a video of what the Raspberry Pi community has achieved every year. He’s just published 2017’s update, and it’s a doozy: have a look, and see how many of these projects and people you recognise!
Half a decade. 12 million Raspberry Pis. On the 28th February 2017, Raspberry Pi will be five years old. As with previous years, I thought that I would make a video to commemorate this historic landmark and to show everyone just what Raspberry Pi is about.
We’re going to be celebrating the community that comes up with this amazing stuff all this weekend at our fifth Big Birthday Weekend, here in Cambridge. Tickets (£5 for over-16s, free for people under 16) are sold out for Saturday, but there are still some left for Sunday: grab them while they’re hot! You’ll see some of the projects featured in this video, discover some completely new ones, have the chance to attend drop-in sessions on digital making, robotics and more, meet with hundreds of like-minded Pi fans, and hang out with the team that makes your Raspberry Pi.
Solar power has surged ahead in recent years, and access for the individual has grown accordingly. Not waiting around for a commercial alternative, Instructables user [taifur] has gone ahead and built himself a solar-powered Bluetooth headset.
Made almost completely of recycled components — reducing e-waste helps us all — only the 1 W flexible solar panel, voltage regulator, and the RN-52 Bluetooth module were purchased for this project. The base of the headset has been converted from [taifur]’s old wired one, meanwhile a salvaged boost converter, and charge controller — for a lithium-ion battery — form the power circuit. An Apple button makes an appearance alongside a control panel for a portable DVD player (of all things), and an MP4 player’s battery. Some careful recovery and reconfiguration work done, reassembly with a little assistance from the handyman’s secret weapon — duct tape — and gobs of hot glue bore a wireless fruit ready to receive the sun’s bounty.
Taking the initiative to go green using solar power– taken literally — could also result in getting into hydroponic gardening.
Instructables user [Roboro] had a Mad Catz Xbox steering wheel controller he hasn’t had much use for of late, so he decided to hack and use it as a controller for a robot instead.
Conceivably, you could use any RC car, but [Roboro] is reusing one he used for a robot sumo competition a few years back. Cracking open the controller revealed a warren of wires that were — surprise, surprise — grouped and labelled, making for a far less painful hacking process. Of course, [Roboro] is only using the Xbox button for power, the player-two LED to show the connection status, the wheel, and the pedals, but knowing which wires are which might come in handy later.
An Arduino Uno in the wheel and a Nano in the robot are connected via CC41-A Bluetooth modules which — despite having less functionality than the HM10 module they’re cloned from — perform admirably. A bit of code and integration of a SN754410 H-bridge motor driver — the Arduino doesn’t supply enough current to [Roboro]’s robot’s motors — and the little robot’s ready for its test drive.
[Roboro]’s suggested improvements are servo steering for the robot, upgrading to the HM10 module, more sensors to take advantage of the other buttons on the wheel, and a camera — because who doesn’t love some good ol’ fashioned FPV racing?
