LEAP#422 VL53L0X Laser Tape Measure
The VL53L0X is a very small Time-of-Flight (ToF) ranging sensor. It is quite widely available as a module, including from Adafruit - see their information page.
For this project I’m taking the module for a test drive and building a short-range tape measure with an Arduino and Nokia 5110 display.

LEAP#421 LimeSDR First Look
I think I first heard about LimeSDR-USB on The Amp Hour.
I was convinced to jump in and give it a go particularly because of the fully open-source nature of the platform - from hardware all the way to software, including FPGA code.
The unit is suited to research and development in a wide range of areas, but I suspect as I get more into this I will be mainly focused on areas such as test and measurement (e.g. spectrum analysis) and amateur radio.

There are some good video resource, a good place to start is: What is the LimeSDR?

LEAP#420 CuttleTalk Audio over LiFi
Now I’ve built the Boldport lite2sound, time to test it out. I’m inspired by LEAP#417 SimpleSamplePlayer to attempt some LiFi audio transmission by light.
I’m using the Boldport Cuttle (an AVR/Arduino clone) to transmit an audio sample with an LED, and the Boldport lite2sound as a receiver. The audio out from lite2sound is amplified with LEAP#210 TDA7297 Kit.

And it works;-) I think I’ve found the Spirit of Saar in the Cuttle..

LEAP#419 Boldport Lite2Sound
The Boldport Lite2Sound BC is a crafty collaboration with Rare Waves LLC. It uses a photodiode to detect audio-frequencies from light, which are amplified and piped to an audio jack (or optionally to direct line-out).
Best of all - it comes in an Altoids-sized can!
