MVFD Panel and Regular Arduino

Today we are publishing photos of fully assembled and tested MVFD 16S8D Panel, Rev 2.0. The board on the pictures is fully populated with components which means that apart from displaying alphanumeric information it can measure ambient light intensity, emit simple ‘beep’, receive signals from an IR remote control and shine with an RGB LED. […]

Luminardo: Fabrication and Assembling

Before STL models can be sent to a 3D printer they need to be converted into format recognized by a specific make and model of a printer. This job is usually done by software distributed with a printer. Besides, additional manipulations need to be done: the model must be properly positioned at the very centre […]

Luminardo: Designing Enclosure

The idea of making enclosure fully out of acrylic panels was abandoned due to ‘squarish’ look of the final product. We really wanted to create something a little bit more stylish and this is why the most obvious choice was 3D printing. That way it was possible to make rounded corners and streamline shape. However, […]

A 16S8D VFD Panel Revamp: Revision 2.0

This is a deep redesign of MVFD 16S8D Panel Rev.1.0 project which fixes minor and major issues and finally solves the fundamental problem of some parts becoming obsolete. Let’s reiterate the reasons which were the main driving forces of the project to come into existence:

– Single power source (+5V) which makes it possible to […]

Revisiting VFD PSU – Part III

It is time to test our revisited VFD PSU in real life. We are going to build a quick prototype using a PCB from MVFD 16S7D Panel with minimum components loaded. All we need to solder is a VFD controller IC2 (instead of HT16515 we are going to use PT6315 as they are pin-to-pin compatible), […]

Revisiting VFD PSU – Part II

We are continuing our experiments with an alternative VFD power supply which we started some time ago. The high voltage part remains pretty much unchanged for now – it is an inverting regulator based on inexpensive chip MC34063. Excessive current consumption (60-70mA) in idling mode is still an issue but we are not going to […]

Revisiting VFD PSU – Part I

The need in inexpensive, simple and compact power supply unit (PSU) for VFD projects has always been topical for us. MVFD 16S8D Panel was designed to address the challenge, however, as it always the case for first revision, there are some things which require improvements or rethinking. And MVFD Panel was not an exception in […]

Luminardo: Intergation with MVFD 16S8D Panel

Luminardo motherboard and MVFD 16S8D Panel were specifically designed to fit together. That is why both PCBAs have the same board outline and matching mount holes. Two PCBAs interconnected by a 2 row 14 pin header, named as P8 on motherboard side and as JP2 on VFD panel side. In order to do the assembling […]

MVFD Panel in 3D

Building a 3D model from PCB design files can bring your project to a totally new level. It comes at a price as it requires extra design time but being properly done it saves a lot of effort and money in the future as it minimises risks by helping to capture issues on early stages […]

How To Make Sound A Total Failure Project

Inspired by the success of VFD MagiClock a decision to make something similar but out of new parts was made. To be fair, despite its appealing look the original clock was assembled using scrapped parts making it really difficult to replicate. In addition to that, rather substantial dimensions and necessity to have cumbersome power supply […]
