LEAP#370 TS3A5018 Digital Switch

Just a quick test of the TS3A5018 digital switch which I am looking at for an application in switching amplifier gain stages.

The TS3A5018 is a 1.8 to 3.6V device with four SPDT switches controlled from a single input, and a master active-low enable pin. It is guaranteed break-before-make (max 58ns).

LEAP#369 my beeping Boldport ananas

Boldport Club Project #20 is the first designed by Ben, the new Boldporter. And it’s a beauty!

As is often the case, a small but interesting circuit is at the core of a beautiful design. The circuit is essentially four repetitions of an RC phase-shift oscillator. Like other projects such as the famous Cordwood series, the design employs multi-board symmetry and 3D construction.

LEAP#368 Granular Synth

The “Granular Synth” idea harks back to an old Auduino project. I stumbled upon it again recently and decided it deserved a quick build in an Altoids tin ..

.. because granular synthesis is a basically how they make Altoids, right?

If you can put up with 5 minutes of me fiddling around, here’s a taste of how it performs..

LEAP#367 nRF24 Scanner

While trying to improve the range of nRF24L01+ some modules, and got distracted into building a channel scanner. The basic code is from the RF24 library examples, but this gets pimped up with a Nokia 5110 LCD display, multiple modes and a handy enclosure.
