  • 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…

  • Focus stacking and other modifications for the Bresser Infinity Microscope

    Work in progress – further details to be added! Important note regarding powering the relay board used to switch the ring-light power supply! It turns out that the relay board I used and probably many others, draw too much current to be powered from the Arduino 5V or 3.3V pins which allow a maximum current…

  • Adding a camera to the Bresser Infinity Microscope

    The Bresser Infinity microscope is pretty good but like all microscopes it has its limitations. I am a passionate macro-photographer and thus a camera port on a microscope was a ‘must’ for me. A few minutes reading on the microscope forums provides some information on how to best utilize the port but also flaged up…

  • 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…

  • Bresser Infinity Microscope

    I seem to be writing another review. Mostly, I hold back from them because I don’t feel sufficiently expert to be able to express a strong opinion. However, in this case I think I can. Why? Well, I have been using microscopes for more than 50 years (God! Is it really that long!). I have…
