Josh's thread on RFM builts and 3D cases

[Joshua]

Hey folks,

I'm converting my home IOT system from zwave to the RFM and ESP nodes in this forum. I'll share the construction of each node along with the 3d design files. Here's the list of nodes I plan to post.

RFM Devices

- Gateway

- Door

- Motion/Temperature/Humidity

- Garage

- Current

- LED controller

ESP Devices can be found on the OpenHAB & ESP8266 WiFi Devices board here.

- Dimmer

- Relay switches

Gateway Node....

I've made some minor changes to the case design since an older post in a different thread.

Parts list (in addition to the Arduino and radio)

- Trimmed down Details 5cm x 7cm PCB Prototyping Perf Boards Breadboard

- JST 2.0mm PH 2-Pin Female Connector Plug with Wire 26AWG & Male Connector

- 2.54mm PCB Board 2 Row 24 Pins DIP Solder Type IC Socket Adapter

- REED SWITCH 2 X 14 mm Plastic Normally Open

- ***Omnipolar Digital Hall-effect Sensor SS451A (Not in use anymore)

- 10K Ohm resistor (Not in use anymore)

- 420mah LiPo battery

- Small Neodymium Mini Magnets

***I've switched from the hall sensor to a reed switch because I suspect that the hall sensor is causing excessive battery drain.

I love Command Picture Hanging Strips to mount most things to walls. It's a great product that is reusable (for the same location) and allows one to remove and install the node over and over.

Arduino Pro Mini with a RFM radio built with the smallest footprint I can, reasonably, manage.

Parts list (in addition to the Arduino and radio)
- Trimmed down 5cm x 7cm PCB Prototyping Perf Boards Breadboard
- 2.54mm PCB Board 2 Row 24 Pins DIP Solder Type IC Socket Adapter

- 420mah LiPo battery (pick your own size battery)

- JST 2.0mm PH 2-Pin Female Connector Plug with Wire 26AWG & Male Connector

Nice work, Joshua. Nice pictures. Neat enclosures. Good to have some new activity on the forum.

Your posts would be even more helpful if you added links for possible sources of parts, like for...

- Trimmed down Details 5cm x 7cm PCB Prototyping Perf Boards Breadboard
- Omnipolar Digital Hall-effect Sensor SS451A
- 420mah LiPo battery
- Small Neodymium Mini Magnets

I look forward to your upcoming posts on other projects. (I've been working on something I hope to post before too long.)

Another good contribution, Joshua. Neat use of phone jacks & phone-type cables.

Thanks also for providing links to sources for the parts.

Here are the devices enabled for this project
#define RELAY2 // control a load 2. Brump added.
#define RELAY3 // control a load 3. Brump added.
#define CURSEN // Monitoring the AC current on all loads. Brump added.

**As of 18-09-23, this was not fully working. We worked through the issue here.  papa:  See this post confirming that this works now & the sketch has been updated.**

Parts list (in addition to the Arduino and radio)
- Trimmed down Details 5cm x 7cm PCB Prototyping Perf Boards Breadboard

- RJ11 Plug 6P4C Phone Modular Telephone Cord Connector 

- CAT3 Keystone Jack RJ11 6P4C Phone Telephone

- 5A Range Current Sensor Module ACS712

- AC-DC 220V to 5V 600mA 3W Isolated Switching Step Down Power Supply Module

- DC/DC 4.5V-7V to 3.3V AMS1117-3.3V Power Supply Module Volt Regulator N24

- 2 Channel DC 5V Relay Switch Module

- 120V DUPLEX RECEPTACLE WALL OUTLET PLUG

This is a housing for a powered Arduino Pro Mini to control a 3D printer power supply as well as the filament cooling while monitoring the current draw of the printer. I developed this in order to have the ability to power the 3D printer on and off, power the filament cooling fan on and off, and monitor the current draw of the printer. I'll program my home controller (openhab, but I use node red) to monitor the printer current in order to power down the both plugs (printer and cooler) once printing is complete and the current draw drops.

This is a modified version of my 3D Controller box. Basically, I removed the current sensor to allow for the ability to just control each side of the duplex plug.
