RGB LED Display test

 Posted on April 19, 2019

First test of a new RGB LED display for a train in Canada. The display has 16 x 144 high power RGB LED’s to make sure it is readable in bright sunlight. The hardware uses a iMX6 CPU and runs a custom Linux OS. Content is send to to display via Ethernet using client specified rail/public transport network protocols. Since it is a multiplex display it is rather difficult to film because the update rate is different from the camera framerate so it looks like it is flickering. [Read More]

New 4 channel Power Supply

 Posted on September 26, 2018

To better handle the power supply needs (3.3V, 5V, 12V, 24V, etc.) of the diverse hardware I work with I replaced my old 3 channel Hameg power supply with a new Rohde&Schwarz HMP4040.

Rohde&Schwarz RTM3004

New 4/16 channel Oscilloscope

 Posted on September 26, 2018

Since almost every project I did the last decades all use something like I2C, SPI, CAN, RS458, etc. I replaced my old Tek scope with a new Rohde&Schwarz RTM3004 that can do decoding of those protocols, so I don’t have to manually count bits anymore.

Since I have several projects for public transportation information systems, where the use of 110VDC is common, I added a BK Precision 150VDC power supply to my lineup of equipment.

BLS Roll-Out

Roll-Out of a new train with a Passenger Information System partially (OS porting, GUI, and build management) written by me. That includes the LED displays on the outside and the TFT displays on the inside, although the inside TFT displays are not visible on this video.
