I wasn’t sure whether it was worth writing this project up, as there are several descriptions already on the internet of people tapping into the Vespa alarm header in order to make a turn signal beeper. However the ones I’ve seen are all very simple direct connections of a piezo buzzer to the turn … Continue reading A Turn Signal Beeper for the Vespa GTS 300
UPDATE: People smarter than me have realised that you do not need to go to the trouble of de-soldering the buzzer – you just need to remove the metal diaphram from the buzzer. See their excellent comments below this post. Stopping a KitchenAid kettle from beeping, at all. My wife and I were recently in … Continue reading De-Beeping a KitchenAid Kettle
For a while I’ve been keen to build a solar powered charger for my phone and iPad, mainly because I wanted to have a play with solar power – something I haven’t done before. It certainly wasn’t to save money. I think I calculated that it would take several lifetimes of daily device charging to … Continue reading Solar iDevice Charger in Atomic Punk Style
Combining Coffee and Electronics – An Idea for a Project Having played around with fixed function logic ICs, such as the Johnson counter used in the Spindicator project, I was keen to move on and experiment with programmable microcontrollers. I decided to obtain and play with some PICAXE chips, as they looked like they would provide an … Continue reading Pimp My Rocket (Espresso Machine)
I’ve had a couple of questions asking about using capacitors to fade out the LEDs of the spindicator to give a sort of trail effect, and I thought I’d like to try it myself. So let’s get straight to the circuit. The first thing to note is that in this version I have used the … Continue reading Spindicator Mk 2–Now With Fade Effect.
In this post I’m going to describe my attempts to date to build a novel computer hard-disk activity indicator, which I named the “spindicator”. The usual hard-disk activity indicator is an LED connected to a header on the motherboard which illuminates when data is being read from or written to the hard drive. These reads … Continue reading The “Spindicator” Project
I recently noticed that when one of my computers entered a sleep state its power LED went off, leaving no way of telling if the computer was asleep or off. When my other computer enters an S3 sleep state, its power LED flashes to let me know. I pulled out the motherboard manual to see … Continue reading Converting a 3-Wire Bi-Colour LED into a 2-Wire Bi-Colour LED
