ESP32-S2 – Deep Sleep & The EN Pin

I’ve been working on a remote control for my cargobot, more on those little teasers soon, and I’ve been having an annoying problem with something that should’ve been simple. The Problem? Switching it on. The controller is running on a Sparkfun ESP32 Thing Plus which has an ESP32-S2 at it’s core. It has an EN […]

A Slight Distraction…

I’ve been planning on building an electric skateboard for a while, that’s where most of the scavenged cells will be going, and while I’m waiting on parts for NE-1 I thought I’d get started. It’s not robot related so it’ll be mostly covered on my Facebook page, link for those interested.

Power Up!

The first job for a few of the scavenged batteries is the Roomba, the existing battery finally gave up the ghost and rather than replacing it again and having to use the slow charger it came with I thought I’d upgrade.
