LEAP#214 OSHChip gcc toolchain
Can I build a program for the OSHChip using the gcc toolchain and Nordic Semi SDK on MacOSX?
Yes..ish!
Here are my notes and scripts for compiling and deploy a simple program, but there remain a few rough edges. There are probably easier ways to do this ... like using the Official Yotta target for OSHChip using gcc ... but I was curious to see how far I could get with just gcc and the Nordic Semi SDK.

LEAP#213 OSHChip blinky
I heard about the OSHChip on the embedded.fm podcast #146 and immediately wanted one!
An ARM Cortex-M0 32 bit micro processor (nRF51822) with 2.4 GHz Radio and other goodies all in a breadboard-compatible DIP16 package .. how could you say no?!
So far, so good. Literally 5 minutes to the first blinking LED, and hours of fun followed .. this is an awesome little package.

LEAP#212 Stay Creative!
A simple project inspired by Make your own LED Sign VU Meter by GreatScott!. The catch-phrase should be familiar if you subscribe to his channel;-)
It's a VU meter, but rather than doing the "bar graph" thing à la LM3915, it pulses the intensity of all LEDs to the volume of the incoming audio.

LEAP#211 Buck Converter Modules
There are many super-cheap buck converter modules available, often based on the LM2596S-ADJ. The "BuckConverterModules" project is where I've recorded notes on the individual units I get to see. So far I've tested four. Two perform really well; two are OK but I have my doubts about the specs of the converter chip.
