  • 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

    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 both steady and that can change with…

  • A novel moth-lamp using LED tapes

    With mercury-based (Hg) lamps now prohibited from manufacture and the availability of new data on moth behaviour concerning their attraction to light (see previous post), it seems appropriate to re-think the design of an LED moth-lamp. I have decided to explore the use of LED tapes. These are available in many different colours (both broad…

  • Rationale for the construction of a new experimental LED-based ‘moth lamp’

    In 2016, I wrote a short blog post concerning the construction of a new LED lamp for the attraction of moths. The rationale was based upon the idea that any lamp designed specifically for the attraction of moths should use LEDs ‘tuned’ to the wavelengths to which the moth’s eye are maximally sensitive. Since the…

  • Of Moths and ‘Mothing’ in the Gresigne

    All my life, I have been interested in insects. My PhD was based around insect eyes, the structure of their eyes and brains, and how they process visual information. My love of insects was almost certainly as a result of my late brother’s passion for butterflies. However, though as a teenager, I used to raise…
