Shop Improvements – Redoing Electrical [Part 2]

In this second part of my shop improvements series I start to tackle the much needed electrical improvements.

Shop Improvements – Part 1

In this first part of my shop improvements series I talk about the various improvements I want to make to my shop and begin by adding a much needed window and doggy door to the shop.

Mailbox Notifier v2.0

This is v2.0 of my mailbox delivery notification system. In this version I scrap the XBee radios, and notification light for an ESP8266 and email notification of delivery. With exception of switching out the Arduino Pro Mini for an ESP8266 and an ATtiny85, all the other core components and construction are the same as v1.0.

v2.0 Code and Schematic

Decent tutorial on setting up Postfix as a relay – I don’t recommend making your server publicly accessible unless you know what you’re doing. If your project does not require secure email, use a service like SMTP2go.

Spark Fun Thing Dev

ATtiny85

DPST relay (use/need is described in video).

DS18B20 Temp Sensor

IP67 Rated LEDs

Reed Switch

Solar Lithium Ion/Polymer Charger

6V 2W Solar Panel

4400mAh Lithium Ion Battery

Custom Bed Frame – Part 8

In Part 8 I stain and apply polyurethane to the frame, make the under bed drawers and add the automatic LED night lights.

I used an ATtiny85 microcontroller with an LDR (Light Dependent Resistor) so I could have the nightlight turn on/off automatically based on light level. The LEDs run on 12v and require 1.8 amps of current (in my case given the length of strip/number of LEDs I used). A MOSFET was used to allow the ATtiny85 to turn the LEDs on/off and also allow it to control the brightness using PWM (Pulse Width Modulation).

Code and schematics (and rough Sketchup drawings of the frame) for the LED controller are available on GitHub.
