A Graphic Interface for the LuciLed illuminator
After a month or so of testing, I considered the LuciLed (Neopixel-based condenser substitute) sufficiently useful to spend the time creating a graphic interface using a Nextion 2.8 (NX3224T028) inch display. Programming Nextions takes a bit of getting used to… to say the very least (!). I had an old Nextion display in my Arduino…

LuciLED – a NeoPixel microscope illuminator – parts and code
The following code runs on an Arduino with a 5 button keypad, I2C 4 line 20 character LCD display, 18 NeoPixel ring and a 3 NeoPixel PCB. The NeoPixel components are mounted on 3D printed parts. See TinkerCad links below for the STL files/designs. Also see below for further information on the other parts and…

The ‘LuciLED’ illuminator – a NeoPixel-based light source for compound microscopes
See end of this article for UPDATES! This is a temporary post to gauge interest in this form of illumination. I emphasize that this is a ‘work in progress’ and that I am happy to acknowledge that it isn’t a substitute for an Abbe condenser though it can produce some very interesting patterns of illumination…

DIY Rheinberg, Darkfield and Other Filters
If you are klutz like me, it’s hard to use most of the techniques one can find on-line for making your own Rheinberg and other microscope filters. Many involve cutting bits of electrical tape or colouring in bits of plastic with marker pens. All credit to those who have the skills to make neat filters…
