In the watchmaking industry there are not only cogs and gears. Nowadays, even the high watchmaking industry focuses on sophisticated digital technology, to combine it with the fine art of mechanics. And it exists, once open-source, even an RTOS owned by Swatch, for which I had the pleasure to use, and mostly to be mentored … Continue reading The EdoSplay project
In need of a new pair of headphones, I wanted to go more towards brands which were less anonymous and more reliable. As I needed a Bluetooth headset but also the Active Noise Cancellation feature for when I work or travel on a train, I wanted to give it a try and I found the … Continue reading Teardown of Marshall MID ANC
One of few repairs that went smooth and succesful. Using a monitor with integrated USB hub can be useful, but also tricky, if such hubs are designed in a cheap way or is not fool proof, and I am a fool. If that is the case, overloading the output lead to a dead port. And … Continue reading AOC I2475PXQU LCD monitor – teardown and repair
I am playing with LEDs for few month and during that time some little projects were born, but now I need a system to handle the logical part and the power distribution. I simply just can't use an Arduino board, or any other development board: I need a proper power handling embedded in a small space, … Continue reading Lino Project
It has been a while since the last LED related article. Was experimented the linear current source, its pros and cons and the field of application. Now arises the need of a small version, handling the same high power, things that are contrapposed in the linear regulator. I need something that I can bring with … Continue reading Tiny, robust, low cost, fail-safe LED driver: the Glighter-S project
A power constant current source, high speed, for power LEDs. Taken all the errors made previously, I tried a new linear based current source which should be kept "simple" and "fast".
Recently I found that today almost lighbulbs are made with power LEDs. And surprisingly most of them are made so cheap that the controller fails far away before its lifetime. At least for what I've experienced with few models. Most of them seems to work well, and I think that LEDs are the future for … Continue reading Current sources for LEDs: firsts DIY impressions
