VESA Mount Arm For Rigol DHO800 Series | Voltlog #474

Elevate your workbench ergonomics with a simple yet ingenious solution – mounting your Rigol DHO800 oscilloscope on an articulated monitor arm. In this innovative setup, I’ll guide you through the process of maximizing your workspace while improving your workflow efficiency. The key to this hack lies in the Rigol DHO800’s standard VESA mount, allowing you to seamlessly integrate it with a monitor arm.

Imagine having your oscilloscope swing in and out of your work area effortlessly, freeing up valuable bench space for other tools and projects. No more awkward positioning or constant rearranging – just a clean, organized setup tailored to your needs. Choosing the right monitor arm is crucial. While high-end options with gas struts and multiple articulating points exist, a simple, spring-based arm like the Maclean MC-458 can be a cost-effective solution.

At just $30, it offers a weight range of up to 7kg, perfect for the lightweight Rigol DHO800 (approximately 1.5kg). If your oscilloscope is too light for the arm’s tension, a clever hack is to add artificial weight using wheel weights from a tire shop. Simply attach them to the VESA mount, and voilà – your oscilloscope will balance perfectly with the arm’s force.

Integrating the monitor arm into an aluminum profile workbench is a breeze, thanks to the standard channel spring nuts and M8 bolts. Adjust the height, angle, and rotation to suit your preferences, and enjoy a truly ergonomic viewing experience.

Adding WiFi Connection To Rigol DHO800 Series | Voltlog #470

Unleash the Full Potential of Your Rigol DHO800 Series Oscilloscope with this Simple WiFi Hack! If you’ve been frustrated by the lack of built-in WiFi connectivity on your Rigol DHO800 series oscilloscope, fear not! Thanks to the ingenuity of the eevblog forum community, there’s a straightforward solution that will allow you to add wireless connectivity to your device with minimal effort.

The key to this hack lies in the Android operating system running underneath the Rigol DHO800 series oscilloscopes. By leveraging the pre-installed drivers for the Realtek RTL8188 chipset, you can transform your oscilloscope into a WiFi-enabled powerhouse with just a simple USB WiFi adapter. To accomplish this, you’ll need to acquire a TP-Link TL-WN725N USB WiFi Adapter (version 2 or 3), which is widely available and affordable.

These adapters are specifically designed with the Realtek RTL8188 chipset, ensuring seamless compatibility with the Android drivers on your oscilloscope. Once you have the adapter, simply connect it to your oscilloscope using a USB hub (along with a keyboard for initial setup), and follow the step-by-step guide provided in the video.

By accessing the Android operating system’s settings through keyboard shortcuts, you can easily connect to your desired WiFi network and enjoy wireless connectivity. While this hack may not be officially supported by Rigol and may exhibit some quirks (such as the GUI showing “network disconnected” despite being connected), the benefits far outweigh the minor inconveniences.

With WiFi connectivity, you can access the oscilloscope’s web control interface, transfer screenshots seamlessly, and even adjust the display brightness – a feature previously unavailable through the GUI.

Mastering PCB Cleaning with an Ultrasonic Cleaner! | Voltlog #467

Keeping your Printed Circuit Boards (PCBs) in pristine condition is crucial for ensuring optimal performance and longevity. While no-clean solder products are available, many fluxes and soldering materials leave residue that can corrode components, cause leakage currents, and compromise the overall aesthetics of your projects.

Fortunately, an ultrasonic cleaner offers a convenient and effective solution for thorough PCB cleaning. In this comprehensive guide, we’ll explore the benefits of using an ultrasonic cleaner, essential safety precautions, and a step-by-step process for achieving impeccable PCB cleaning results. The principle behind ultrasonic cleaning is a phenomenon called cavitation.

High-frequency sound waves create rapid pressure changes within the cleaning solution, generating countless microscopic bubbles that form and implode. As these bubbles collapse near the surface of the PCB, they release intense energy, dislodging dirt, contaminants, and residue from even the most hard-to-reach areas.

Before diving into the cleaning process, it’s crucial to observe a few safety precautions. Firstly, never run an ultrasonic cleaner dry, as it can overheat and damage the unit. Secondly, avoid using flammable liquids, as they pose a fire risk when heated. Lastly, consult component datasheets to ensure that the parts can withstand ultrasonic cleaning and submersion in liquids.

To achieve optimal cleaning results, choose a high-quality ultrasonic cleaner like the VEVOR Ultrasonic Cleaning Machine, which offers adjustable temperature, cleaning time, and ultrasonic power settings. Pair it with a suitable cleaning solution and deionized water for best results. The cleaning process itself is straightforward: fill the cleaner with the appropriate solution, submerge the PCB, and let the ultrasonic waves work their magic.

Post-cleaning steps include rinsing the PCB in deionized water and drying it with compressed air. One of the significant advantages of ultrasonic cleaning is its ability to dislodge residue from hard-to-reach areas, such as between component leads and under IC packages, ensuring a level of cleanliness unachievable through manual brushing alone.
