Here's the completed "404 monitor" project. It uses the Futaba M404SD01 module I have shown you previously. In its final configuration, the Futaba module is paired with an Arduino Mega 2560. The Mega uses one serial port to monitor a Raspberry Pi 3, and the other serial port to send data to the Futaba module.

The RPi3 runs dnsmasq and is the DNS name server for my local network. It generates the display you see on the Futaba module. On the first line is the day, date, and uptime. The second line displays the RPi's IP addresses for ethernet and wi-fi. The Third line shows the system load (output of /proc/loadavg). The fourth line shows a graph of the system load.

All this display information is generated on the Raspberry Pi by a python script. The Arduino Mega has the Futaba drive logic and a simple "echo" program that takes input from the Rpi and sends it to the Futaba module. The only display content generated in the Mega is a timeout display; if the Mega doesn't receive any data from the Rpi in 60 seconds, it displays a "HOST NOT RESPONDING" message.

(Photographic note: Previously my photos have been taken with an iPhone 6s on iPad Pro for convenience; the photo quality isn't always amazing because the light emitting from VFDs and LEDs tends to just overwhelm these camera's automatic settings. For these two photos I used a DSLR in shutter-priority mode at 1/30 S; I think they turned out much better. Incidentally, that's the same camera setting I was using 30 years ago to get decent shots of my TV screen to record the output from my TRS-80 Color Computer. Some things never change.)

Here's the construction manual for the Space Invader game I posted the other day. It's Arduino based and uses a 32x32 LED matrix panel from Adafruit (I've got of few of them -- they're nice and very bright).

A VFD + GPS prototype I threw together last year. It's a Futaba GP9002 VFD module I bought off ebay, one of Sparkfun's nice little GP-20U7 GPS units, tied together by an Arduino Nano. The VFD driver software comes from Adafruit. The GPS software is my custom brew. The VFD and GPS modules will wind up in separate projects; this prototype was just to test them out. I thought y'all might like to see it.

Seen this on the arduino forum. Also with pacman... hand held and framed its cool.

Static test of the gorgeous new ИВ-27M that arrived this morning. It shows a very strong brightness gradient; I'm thinking that's probably because I'm driving the filament with DC and that it'll go away when I have a proper biased-AC to drive the filament with (still working on that circuit).

Here's a static test of one of the 7-dot VFD tubes I received last week. These look great. Thinking of buying a bunch of these (two bucks a pop at tubes-store.com) to make a beautiful 7x5 pixel x 4 character display.

From Russia with love: some IV-26 and IVLM1-1/7 VFD dot tubes I received today from tubes-store.com. These have a future home in one of my Arduino projects. Tonight I'll post some photos of them lit up.
