Arduino Provides Hands-Free Focus for Digital Inspection Scope

With surface-mount technology pushing the size of components ever smaller, even the most eagle-eyed among us needs some kind of optical assistance to do PCB work. Lots of microscopes have digital cameras too, which can be a big help – unless the camera fights you.

Faced with a camera whose idea of autofocus targets on didn’t quite coincide with his, [Scott M. Baker] took matters into his own hands – foot, actually – by replacing mouse inputs to the camera with an outboard controller. His particular camera’s autofocus can be turned off, but only via mouse clicks on the camera’s …read more

Seeing a Webcam’s PCBs in a Whole Different Light

When it comes to inspection of printed circuits, most of us rely on the Mark I eyeball to see how we did with the soldering iron or reflow oven. And even when we need the help of some kind of microscope, our inspections are still firmly in the visible part of the electromagnetic spectrum. Pushing the frequency up a few orders of magnitude and inspecting PCBs with X-rays is a thing, though, and can reveal so much more than what the eye can see.

Unlike most of us, [Tom Anderson] has access to X-ray inspection equipment in the course of …read more

LEGO Components Under X-Ray

[Nico71] works for a company that makes industrial CT scanners. These x-ray machines look inside a piece of equipment, allowing operators to verify assembly and to inspect for material integrity. It also allowed [Nico71] the opportunity to scan a LEGO servo he had lying around, and which no longer worked. The resulting images look fantastic, and really allow you to look into a closed system and pick apart how it works or why it’s not working. In this case, you can see one of the wires has been damaged.

[Nico71] plans to scan a bunch of LEGO components, comparing (for …read more

Hackaday Prize Entry: SafeRanger, a Roving Power Plant Monitor

Engineering student [Varun Suresh] designed his SafeRanger rover to inspect oil and gas power plants for abnormal temperatures as well as gas leaks. The rover explores critical areas of the factory, and data is sent to a control center for analysis.

[Varun] built his robot around a Devastator chassis kit from DFRobot, and equipped it with a FLIR Lepton thermal camera and an MQ2 gas sensor, both monitored by a Raspberry Pi. The twin brushless DC motors are controlled by an L293D motor driver IC in conjunction with an Arduino Nano; steering is accomplished with an HC-05 Bluetooth module and …read more
