Upgrade Your Budget LC Meter Kit: A DIY Enhancement Project The HU-053 LC Meter kit is a budget-friendly option for measuring capacitance, inductance, and frequency, available online. With its easy-to-solder components and transparent acrylic enclosure, it’s a great weekend project for electronics enthusiasts. But how accurate is it, and can we make it better? Kit Contents and Assembly The HU-053 kit includes a double-sided PCB, a bag of components, a transparent acrylic enclosure, and all the necessary nuts and bolts for assembly. The assembled device measures 91 × 106 mm with a height of 28 mm, featuring an alphanumeric LCD, a 40-pin STC89C52RC microcontroller, a 3P4T function selection switch, and a ZIF socket for connecting the component to be tested. The unit is powered by a 5-V supply. Improving the LC Meter’s Accuracy After assembling and testing the device, we were disappointed to find that its accuracy was as low as its price. But this presented an opportunity to improve it! In this article, we’ll explore ways to enhance the HU-053 LC Meter’s performance, making it a more reliable measurement instrument. Download the article to learn how to upgrade your budget LC Meter kit and turn it into a useful tool for your electronics projects.
This is an upgrade to the Ultimaker2 3D printer for people who have spools that do not fit the original spool holder, and spools that are too tight and thus do not feed smoothly, causing under-extrusion. It is composed of two assemblies: a replacement for the filament guide and a replacement for the spool holder. Both utilizes ordinary skateboard bearings to achieve smooth rotation. The conical shape of the spool holder allows for any sized spool to be used, easily swapped because it uses a wing nut. Files are available on YouMagine. I want to emphasize that I am sharing the STEP files, not just STL, because STL are harder for people to import and modify than STEP files. SolidWorks files are also provided. The cross section images shows you how to assemble the upgrade parts. The screw diameters are #6 for the filament guide and 5/16″ for the spool holder. Please figure everything else out from the cross section images.
