electronic stuff as a hobby
There’s definitely a pattern in these projects. Do I need repetitive tasks to relax ? Do I need scaling-up a simple concept until it becomes unreasonable ?We go again with flipdots, I had a pile of used 7-dots segments, with half-bridge integrated circuits to drive them. Can we imagine a non-standard flipdots matrix? What about [ ]
It s been a while since I ve posted a new project, let s just build something absurd. Here is a supercharged Amazon pencil sharpener. It involved replacing the weak brushed motor powered by AA batteries With a brush-less motor of approximately 100W, powered by lithium batteries. The amazon device is well designed. There is a switch to [ ]
Modular cases I designed cases that can be re-arranged easily for better matrix shape flexibility. It consist of the boxes for the scintillators and different spacers that holds them together. The electronic boards are clicked between the spacers and the front LED diffusers are inserted between the board connectors. Test with antiproton annihilation I finally [ ]
Since the first time I saw the spark chamber at the CERN exhibition nearly 20 years ago, I ve been fascinated by how particle trajectories are directly visible between the plates of these big tubes. This detector shows the paths of muons produced by cosmic rays in the upper atmosphere. It uses two large scintillators placed [ ]
I m a happy user of a Citroën C-Zero. A small electric car, and when it was still produced, one of the lowest power consumption per kilometer. This model was build by Mistubishi and branded by Citroën and Peugeot in EU. By searching on different forums, in particular myimiev.com, I was amazed by people able to [ ]
It is the story of repurposing a broken Garmin watch into a desktop notification display. When focused on a computer task, don t miss any notifications thanks to the absurdity of a desktop notifier. Some time ago I struggle to make a small device displaying the phone notifications on a nice display. I tried with an [ ]
I had a spare transparent monochrome LCD from the darkroom print project. It s been quite a long time I d like to use it to make a monochrome reading display. I recycled an old laptop display backlight, and exchanged the LEDs by orange ones. Even warm white LEDs have a blue component on their light spectrum [ ]
This is a short story about fixing a 1969 Toshiba electronic calculator.
We are back to glowing neon plasma, with yet another clock. The aim is to make some presents to offer to the family, for the end of the year. I previously made a little 6 tubes clock, that was inspired by Dalibor s Zen clock. Here I want to mimic his amazing single tube Bulb clock. [ ]
The ultimate goal of the flipdot project presented in the previous post was to flip each discs in a controlled manner. I secretly hopped to control the position of the discs by applying a pulse width modulated signal maybe like micro-stepping for a stepping motor. And then control at which speed the discs are [ ]
