Real-Time Planet Tracker With Laser-Point Accuracy
Space. The final frontier. Unfortunately, the vast majority of us are planet-locked until further notice. If you are dedicated hobbyist astronomer, you probably already have the rough positions of the planets memorized. But what if you want to know them exactly from the comfort of your room and educate yourself at the same time? [Shubham Paul] has gone the extra parsec to build a Real-Time Planet Tracker that calculates their locations using Kepler’s Laws with exacting precision.
An Arduino Mega provides the brains, while 3.5-turn-pan and 180-degree-tilt servos are the brawn. A potentiometer and switch allow for for planet and mode selection, while a GPS module and an optional MPU9250 gyroscope/magnetometer let it know where you are. Finally a laser pointer shows the planet’s location in a closed room. And then there’s code: a lot of code.
The hardware side of things — as [Shubham Paul] clarifies — looks a little unfinished because the focus of the project is the software with the intent to instruct. They have included all the code they wrote for the RTPT, providing a breakdown in each section for those who are looking to build their own.
There is an extra step to auto-align the RTPT to north, otherwise you’ll have to do so manually. But [Shubham Paul] has designed it so that even if you move the tracker about, the RTPT will readjust its calculations in real time. Each part of the project includes a wealth of related information beyond simple instructions to adequately equip any prospective builders.
This hack gets the job done. If it’s looks you’re after, an artistic expression of maker skills and astronomy can be seen in this planetary map that relies on persistence of vision.

Stage Bench is an Arduino-based live controller table
Manuel Lukas, a student at the University of Applied Science Mainz, and Sascha Lukas, a student at Cologne University of Music, together make up the German pop band Wyoming. As part of an interdisciplinary project, the duo decided to combine their love for both design and music into one live MIDI controller that’s bigger than commonly available commercial devices, but due to its size, more comprehensible for the audience.
The result? A DJ table, dubbed “Stage Bench,” that doubles as an instrument.
Stage Bench is based on an Arduino Uno which interacts with two matrices, a 128-LED matrix and a 128-button matrix, via a pair of shields. The connection to the computer is managed by serial communication and corresponds with a self-programmed patch in Max/MSP, which also sends MIDI data to any preferred DAW to play instruments or samplers.
Check out Stage Bench in Wyoming’s music video below!
Web Editor updates: Import your sketchbook and more
Some useful updates on the Arduino Web Editor!
Are you sticking to the desktop Arduino IDE because all your work is saved locally? That’s no longer a problem! Our brand new import tool enables you to upload your entire sketchbook with just a few clicks on the Arduino Web Editor. It is particularly handy because it lets you move all your sketches and libraries to the cloud in a single flow.
Once your sketches and libraries are online, they will be available on any device and backed up. For details on how to migrate all your code online, check out this tutorial.
Sadly, Codebender is shutting down. You can use the import feature also to easily migrate to the Web Editor. (More details here.)
If you have a big sketchbook, you may want to clean up or categorize things once in awhile. With our bulk action tool, you can delete, move, or download multiple sketches at the same time. Go to the Sketchbook panel, hover on the sketch icon, and select all the files you want to act on. Doubts on how this will work? Learn more in this guide.
What’s coming next?
We are currently working on a super streamlined way to edit your libraries within the Web Editor, and looking for the best way to implement the Chromebook plugin. Stay tuned!
Arduino knight rider circuit using led bargraph
In this post, we are going to make knight rider circuit using led bargraph. Led graph, it consists of 10 leds.
Stuff required:
Source code:
Upload the code below to your arduino board
/* Code starts from here */
const int led[]={4,5,6,7,8,9,10,11,12,13},d=5;
void setup() {
for(int i=0;i<10;i++)
pinMode(led[i],OUTPUT);
}
void loop() {
for(int i=0;i<10;i++)
{
digitalWrite(led[i],HIGH);
delay(d);
digitalWrite(led[i],LOW);
}
for(int j=0;j<8;j++)
{
digitalWrite(led[8-j],HIGH);
delay(d);
digitalWrite(led[8-j],LOW);
}
}
/* Code ends here */

Make Your Own Arduino Header Pins
There are two kinds of people in the world (and, no, this isn’t a binary joke). People who love the Arduino, and people who hate it. If you’ve ever tried to use a standard prototype board to mount on an Arduino, you’ll know what kind of person you are. When you notice the pins aren’t on 0.1 inch centers, you might think, “What the heck were those idiots thinking!” Or, you might say, “How clever! This way the connectors are keyed to prevent mistakes.” From your choice of statement, we can deduce your feelings on the subject.
[Rssalnero] clearly said something different. We weren’t there, but we suspect it was: “Gee. I should 3D print a jig to bend headers to fit.” Actually, he apparently tried to do it by hand (we’ve tried it, too). The results are not usually very good.
He created two simple 3D printed jigs that let you bend an 8-pin header. The first jig bends the correct offset and the second helps you straighten out the ends again. You can see the result in the picture above.
[Rssalnero] notes that the second jig needed reinforcement, so it is made to take 8 pins to use as fulcrums. Probably doesn’t hurt to print the jigs fairly solid and using harder plastic like ABS or PETG, too. Even if you don’t have a 3D printer, this is about a 15 or 30 minute print on any sort of reasonable printer, so make a friend. Worst case, you could have one of the 3D printing vendors make it for you, or buy local.
We love little tool hacks like this. If you are too lazy to snap 8 pins off a 40 pin strip, maybe you’d like some help. If you’d rather go with a custom PC board, you might start here.

Lixie is a Nixie tube alternative
Using a series of etched acrylic panes, the “Lixie” display can show numbers in the style of a Nixie tube.
Nixie tubes are beautiful pieces of display hardware that are no longer in production, and are becoming harder and harder to find. They also generally require relatively high DC voltages to operate, making them difficult and potentially dangerous. Connor Nishijima, however, has come up with an alternative called the Lixie.
This laser-cut item employs etched panes of acrylic to reflect the light from WS2812B LEDs as required, revealing digits 0-9. Since the LEDs are RGB, different colors can be selected as desired.
Edge-lighting panes of acrylic etched with a design has been done for decades, but they’ve always been static information like an “EXIT” sign. If you stack multiple panes of acrylic (each with a unique design) and light them individually, you can change what design the user sees! This makes edge-lighting perfect for a numeric display! And since I love the look of Nixies, we’ll emulate the typography as well. At the end of the day, what I’ve made is a beautiful over-sized numeric display using WS2812Bs and a laser cut digit assembly!
You can find more about this “modernized Nixie tube” on Hackaday.io.
