The place’s Waldo? And what about Carmen Sandiego? There’s something about in search of out and discovering hidden treasures or different mysteries that sparks our curiosity. It begins early with childhood video games of hide-and-seek and continues into maturity with geocaching. If you’re the type that can’t resist a very good thriller, then Gabe Emerson has acquired an actual doozy for you within the wilds of Alaska.
Sadly it’s not as thrilling as a pot of gold on the finish of a rainbow or a pirate’s buried treasure chest, however it’s nearly nearly as good for the intense radio nerd. Emerson has planted a Meshtastic node someplace deep inside Southeastern Alaska. If you will discover it, it’s yours to maintain. However the actual prize is the bragging rights that come together with choosing this needle out of a large haystack.

There is no such thing as a map with an “X” to mark the spot, so you’ll have to sniff the node out with the correct of {hardware}. As a refresher, Meshtastic is a LoRa peer-to-peer community that varieties a mesh to increase its vary. This makes Meshtastic networks significantly helpful for long-distance communications the place present infrastructure is missing or nonexistent.
The first node is a HELTEC LoRa 32 board, which is powered by an ESP32-S3FN8 microcontroller and a Semtech SX1262 LoRa transceiver. After flashing the board with Meshtastic firmware, Emerson positioned it in a weather-proofed case together with a battery, photo voltaic panel, and antenna. In the event you had large plans for the included OLED show, you may be somewhat dissatisfied. It was eliminated to assist the board match within the case.
A pair of smaller, droppable breadcrumb nodes had been additionally constructed utilizing {hardware} such because the RAK WisBlock, together with low-cost photo voltaic cells, batteries, and circumstances. These cheap nodes could be sprinkled round to assist paved the way to the first node. The entire nodes had been pretty cheap, coming in at round $40 to $50 every.

Making a particular journey to Alaska could also be out of the query to find a $50 Meshtastic node, however Emerson did drop a reasonably large trace. The node is close to the ocean and cruise ships incessantly move inside vary. So when you’ve got an Alaskan cruise deliberate within the close to future, be sure you deliver some gear together with you (as in the event you’d be caught with out it anyway).
If Alaska isn’t in your future, you’ll be able to nonetheless have some enjoyable with Meshtastic units. The Meshtastic System Design Problem is underway at Hackster, and much more than a $50 node is up for grabs. There may be over $7,000 in prizes at stake, so get your self entered at this time and begin designing a novel product that makes use of mesh networking.
