DIY Arduino 3D Laser Scanner

FabScan is an open-source, do-it-yourself 3D laser scanner.It started out as a Bachelor's thesis by Francis Engelmann, supervised by René Bohne. You can find official project here. I made my own box from MDF hood sheets and use different hardware parts.I decided to make this guide to show to you my work. All credits for Arduino software and computer application goes to FabScan team, so thank you very m ...

Creating footprints in KiCad using a scanner

Some time ago I sourced a number of very cheap SD card sockets from China for a hobby project I was working on. Sadly, when it came to PCB design, I couldn’t find the footprints for this particular socket anywhere – the part being a proprietary invention of the factory rather than a cheap knockoff of a reputable brand like Amphenol or Molex for which drawings are readily available off of snapeda.com. Turns ...

2D-SCANNER RECORDS SURFBOARD PROFILES FOR POSTERITY

[Ryan Schenk] had a problem: he built the perfect surfboard. Normally that wouldn’t present a problem, but in this case, it did because [Ryan] had no idea how he carved the gentle curves on the bottom of the board. So he built this homebrew 2D-scanner to make the job of replicating his hand-carved board a bit easier. Dubbed the Scanbot 69420 – interpretation of the number is left as an exercise for the read ...

BARCODE GUITAR PLAYS MORE THAN BEEP-BOP

One of our favorite things about the rise of hobbyist development ecosystems such as the Arduino is that it’s now possible to make a MIDI controller out of almost anything, as long as you have the the shields and the dedication. We’re glad that [James Bruton] takes the occasional break from making robots to detour into instrument making, because his latest creation turns it up to 11. This awesome guita ...

Barcode scanner MIDI guitar made using Arduino and acrade machine parts

Maker and 3D printing enthusiast James Bruton has created a new project in the form of a barcode scanner MIDI guitar. Using parts from old arcade machines and the little Arduino programming and an Arduino MEGA with a USB host shield and a MIDI shield, the unique musical instrument uses barcodes to create sounds. Watch the demonstration video below to learn more and see the barcode scanner MIDI guitar inacti ...

AN ARDUINO SICKBAY DISPLAY WORTHY OF THE ENTERPRISE

The various displays and interfaces in Star Trek, especially The Original Series, were intentionally designed to be obtuse and overly complex so they would appear futuristic to the audience. If you can figure out how Sulu was able to fly the Enterprise with an array of unlabeled buttons and rocker switches, we’d love to hear it. But one area of the ship where this abstract design aesthetic was backed off a ...

USB 3.0—Everything you need to know

USB 3.0—Everything you need to know In the last 14 years, the Universal Serial Bus (USB) has become the standard interface to connect devices to a computer. Whether it’s an external hard drive, a camera, the mouse, a printer, or a scanner, the physical connection to transfer data between devices generally is a USB cable. The interface is indeed universal. USB technology has been under development since 1993 ...

A HIGH-SPEED SLIDE SCANNER BUILD

Photographic slides were popular in the middle part of the 20th century, but are long forgotten now. If you’ve found a handful in a dusty attic, you might consider sending them away to be digitized professionally, or using a flatbed scanner at home. [Bryan Howard] found himself with over 200,000 slides, however, so that just wouldn’t do. Instead, he endeavored to build an automated scanner of his own.  Like ...

DIY 32ch FPV 5.8ghz LCD

If you’re like me, you don like buying stuff that’s ready-to-go, but rather build one yourself. We usually spend more money, but it’s way more satisfying ? I really didn’t want to buy an overly expensive 32ch FPV LCD receiver, so I made my own DIY 32ch FPV 5.8ghz LCD, that is compatible with EVERY transmitter on the market now. Lets begin! First, crack open that LCD, and look what’s inside. I desoldered the ...

xy-ray x-ray scanner

In some previous posts I talked about getting an x-ray head working, reverse engineering an x-ray sensor, and working with LinuxCNC.  In this post I put them all together so that I can take a bunch of x-ray snapshots across an entire PCB.  This allows me to more quickly reverse engineer PCBs. Problem: with my previous work I can take a PCB x-ray at fairly high resolution (see bond wires like above) but the ...

Arduino and CueCat barcode scanner

I've had a cuecat barcode scanner sitting around for over 10 years. Basically it connects to a PS2 port (apparently there is a USB version) like a keyboard and spits out a barcode when scanned. Nice!. The annoying thing is that it is "encrypted". What I set out to do is; - unencrypt the barcode in software on the arduino - i didn't want to cut into the Cuecat in case I broke it, not hard to replace, but tha ...
