During EMF Camp 2022, you can find me at the [[Village:Unaffiliated|"Unaffiliated" Village]]

Will bring a [https://www.thethingsnetwork.org/ The Things Network] gateway for LoRaWAN coverage. See [[Interest:LoRaWAN]] if you want to have a chat on this topic!

BastiaanSlee:

LoRa is the technique to send messages on the free wireless ISM network bands. The method is based on Chirps, which is an old radar technique. Sending data goes super-slow. Think about Morse coding, LoRa is slower... But by using this technique, with low power, a message can be send that survives a lot of noise, meaning it can be picked up by a gateway on a much further distance.

These gateways can be deployed by everybody, and can be private (costs might be involved) or public (free!). The Things Network did build a backbone for the gateways, and a transport protocol with front-end website to monitor your gateway and device. That is where the term LoRaWAN comes in; it is the full stack end-to-end to send and receive a message.

To make use of projects based on LoRaWAN, you need to be within reach of a gateway. Otherwise it will send your messages, but they will never get received.
On the EMF campground, it looks like there is no coverage. That is why we bring a LoRaWAN gateway based on a Raspberry Pi + RAK 2245 + good antenna, plugged in to the EMF Camp network. This should give a coverage of about 10km (~6 miles), plenty of range for the full campsite!

With LoRaWAN the tricks are in the little details:
* Hardware: let your device sleep most of the time (temperature every 60 seconds? Or is once an hour enough?), so your device can run on a coin cell battery for a looooong time
* Payload: the smaller your message (temperature in 4 digit precision? Or is once an hour with 1 digit enough?), you need less radio time, less sending power, so you get longer battery life!
* In short, acquire only useful data: Your sensor can track temperature, humidity, air quality, acceleration, gps and send that up to the network every minute. But you actually only need the GPS location, when the sensor moves. Again, it is all about the balancing game for longest battery life!

If there is interest on this topic (also Helium, NBIoT, etc), we can organize some meetup!

| Jon || Created another village like this in 2012, back when I knew no one. Doing it again 12 years later to provide a home for people who would like a softer entry to EMF than trying to find a space in the field. || 25m 16A ceeform to ceeform cable, some addressable LED strip (no power supply, or anything to drive it though), 3 other people (if you're one of those people, add your name below and decrement that count)
|-
| [[User:GrantPe|Peter]] || Absolutely new to EMF. Works with computers, makes things in wood, fabric, plastic, occasionally basic electronics and metal work. || 25m 16a Ceeform to Ceeform cable, 15m Ceeform to 3x 13a sockets, kettle and stove, two smallish camping tables.
|-
| Edwin || Also a hacker camp newbie! Software hacker for fun and also for a living, radio ham, sometime musician. ||

| Raz || First time at EMF / any hacker camp, keen to meet other newbies! Computational chemist from London, (very) amateur musician, Emily's boyfriend. ||

| [[User:Andy Fletcher|Andy Fletcher]] || First time at EMF. Off grid in South Shropshire. Love to talk about Solar power, battery systems, inverters, CO2 and climate change. Yes you can run your house purely on solar in the UK :) - Offgrid PV photovoltaic LiFePO4 ||
|-
| [[User:Niamhishere|Niamhishere]] || EMF second timer but now with some different dimensions. Have son, will play arcade games, prefer if the village is on the quiet side for the night. ||

|-
| Hopo || Connected to Leicester Hackspace, but we havent got a contingency at EMF this year. Last attended in 2016. A creator of things with LEDs, mechatronics, and general tinkering. Looking to discover new exiting people and things. || 2mx2m LED curtain, can be freestanding (to walk through) or attached to the side of a marquee/tent. If this can be visible from the 'street' that would be much appreciated. Also, a Thermal Grill Illusion that I would like to be able to set up in the event shelter for people to play with if possible, smaller than a cat-carrier, needs mains. I also have a sand-table, but still needs some (software) work so unsure if to bring that or not.
|-
| Soph || Connected to Leicester Hackspace as above, First time at EMF. Interested in performance arts and installations, fabric creations and bright colours. Looking to meet some interesting people and do some fun things. || We (Hopo & I) can bring an additional gazebo or another little gas stove etc. We have various camping supplies if needed.

== Activities ==

TBC

Maybe a How to EMF workshop? Nothing concrete yet.

Preferably Camping F or nearby - but not decided yet.

Having the event shelter in the centre, with tents around could be an idea.

Should leave a path out to the main road for ease of access.
