The updated MP3 Trigger V24 from SparkFun is now for sale. This new version features improved firmware that can read a configuration file from the SD card, making it much easier to use without a microcontroller. We posted previously about a project using an A-Star 32U4 and an MP3 Trigger to make a Scary shaking tombstone. The MP3 trigger also pairs nicely with the Maestro Servo Controllers because you can use a Maestro servo controller’s scripting capability to trigger sounds to play in sync with motion. You can see examples of how people are using them on our forum here and here.

Opportunities: Growing outdoor and camping activities are likely to increase the use of portable power stations
There is a rise in recreational and camping activities, such as fishing and hiking, mainly in North America. According to the North American Camping Report of 2019, there has been an addition of 7 million new camper households in the US, and the percentage of people camping has increased by 72% since 2014. In addition, to the increase in new campers, more Gen X campers (38%) and millennials (32%) have begun identifying themselves as campers and frequently go camping. According to Tourism Research Australia, in 2019, total tourism, which included domestic and international tours, accounted for USD 152 billion. In Australia, people visiting hotels, motels, and resorts accounted for 24%, and people going for caravanning and camping accounted for 14%. According to Eurostat, two-thirds of European campsites are located in 5 countries, namely the UK, France, Germany, Italy, and the Netherlands. In 2017, camping visitors spent a total of 397 million nights across EU campsites.
With the growing need to stay connected and millennials opting for camping, there is a demand for various electronic equipment such as laptops, smartphones, rechargeable trekking head torches, camping lamps, fridges, and cooler backpacks. All these devices need the power to keep them working, which increases the opportunities to use portable power stations.
