Lumunardo in White Case and Blue Screen

Introducing a more stylish look of the enclosure made of white PLA material and translucent blue front and rear panels. It is very hard to find acrylic material other than transparent white with 2mm thickness so we had to modify the top and bottom shells to be able to fit 3mm thick panels.

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 Luminardo Board Revamp: Revision 2.1

This is a second spin of Luminardo boards with the focus on elimination minor mistakes found in the revision 1.0. A motion sensor is fully integrated with the PCB this is why the board has an inflow on top of its outline. Also an obsolete inductor is replaced with the one of a similar footprint […]

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 […]

Electronic OBDII Gauge on Luminardo

Let’s make something more complex using Luminardo, a Bluetooth dongle, a OBDII translator ELM327 and a 128×64 pixels graphical monochrome OLED display SSD1306. The plan would be to utilise USB host functionality to communicate to ELM327 via SPP interface and represent such parameters as engine RPM, vehicle speed, battery voltage, remaining fuel on a display. […]

Interfacing SSD1306 OLED Display with Luminardo

Some time ago we began looking for alternative displays for our Luminardo project and got inspired by a DIY OLED interface board. The author found cheap monochrome OLED displays on Ebay, designed an interface board and wrote a C library. In addition to that some more information on driving such display type was found at […]

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 […]

VFD Color Filter Made of Plastic Glass

Stylish and professionally looking enclosures for DIY electronics is a known challenge for both beginners and advanced hobbysts. Custom made cases are either too expensive, too difficult/time consuming to build or the resulted forms are too primitive/ugly. Besides, electronics engineers usually are not exceptionally good at 3D designing and they tend to consider assembled and […]

Mini Maker Faire 2014

Just recently we had an opportunity to participate in Sydney’s Mini Maker Faire 2014. This was the second event of a kind being organised at Powerhouse Museum in Sydney. The decision to take part has been made spontaneously and one only week before ‘the day’ which, to some extent, contributed to our poor performance and […]

Envisaging Case for Luminardo

Recently we have been busy working on new stylish case for Luminardo project. The challenge is to design something which would cost reasonable price and at the same time have modern look. Making cases of acrylic panels by laser cutting them is relatively inexpensive but all cases look kinda the same – like ugly boxes. […]
