Building Tube Amps Builds builds your knowledge and skills There are many many ways to build an amplifier, depending on money and time available, choosing the most expensive components, creating (or again, buy) a custom metal chassis (or have a friend that can make many as you want) with the objective to obtain a better build for the same price. Building tube amps is very rewarding, and can keep you busy with its fair amount of metalwork and various power tools, like folding machines, press, lathe, milling machines and uncountable hand tools.

For some years I worked with and published mobile apps. Albeit mostly on the iOS Apple platform, I ventured into porting onto Android (JAVA, Kotlin) as well. This post lists the apps I worked on, worth of being published. Make sure you check those open-source ones, as their code is available for download. Modern software programs usually known as Apps… Tip Unless otherwise stated, I took care of designing all the graphical elements of the apps designing the UI/UX creating the promo videos writing/arranging the musics everything else ANTOINE: that little Prince 🤴 This text reader App implements a pretty new and interactive paradigm to enjoy a written story.

DI Box a simple audio preamplifier for dynamic microphones with internal noiseless power supply (AC powered). Class A FET input stage with high linearity and large bandwidth. XLR input with gain control Line output (balanced/unbalanced) low noise and low distortion high bandwidth Found in need to record sounds with a Shure SM58 into a computer, I decided to build my own little preamplifier so I could plug it to the Mac’s line input jack and have a decent timbre and a low noise figure by choosing a voltage controlled amplifier using a single FET, well known for their tube-like sonority and their advantages over a current controller amp.

I designed these leaflets for a jam session night at Bar dello Sport, Serramonacesca using the images of Tjalas, the aboriginal name for this specimen of honey pot ants in central Australia, with their abdomen swollen with the sweetest honey you could ever think of. We were staying in Serramonacesca, me and my old lady. Used often to spend there some holidays together. I got this invitation to a jam session night while drinking at the very place with the locals.

BTTF This is a semi-serious rendition of the story behind making this project: A replica of the time machine circuits from the Back To The Future blockbuster with talking alarm clock. Apart from actual time travel, which might be even possible depending on your time-zone, internet provider and your skills in creating your own flux-capacitor, it works as a nice talking alarm clock with the most famous quotes from the original movie.
