Morten Linderud ☛ Easter hack: terraform-provider-openwrt
So getting the OpenWrt One router it seemed like a nice excuse to figure out if there was any teraform providers available. And quite disappointingly there was not any out there actively maintained. So I guess we’ll have to write our own!
OpenWrt has a JSON-RPC API that allows you to set configuration files, and options, through a set of calls. So writing a thin wrapper around this API with a bit of plumbing does not seem to be too difficult.

Hackaday ☛ A Pi-Based LiDAR Scanner
Although there are plenty of methods for effectively imaging a 3D space, LiDAR is widely regarded as one of the most effective methods. These systems use a rapid succession of laser pulses over a wide area to create an accurate 3D map. Early LiDAR systems were cumbersome and expensive but as the march of time continues on, these systems have become much more accessible to the average person. So much so that you can quickly attach one to a Raspberry Pi and perform LiDAR imaging for a very reasonable cost.

CNX Software ☛ Openviro Axe PoE is an RP2040-based environmental sensor for server rooms and cabinets (Crowdfunding)
Openviro Axe PoE is a rack-mountable, open-source environmental sensor designed to measure the temperature and humidity (and air pressure) in server rooms or cabinets with electrical equipment. The device is based on a Raspberry Pi RP2040 board with Ethernet connectivity housed in a plastic enclosure and equipped with two RJ12 connectors for Bosch BME280 sensors with an accuracy of +/- 0.5°C.

CNX Software ☛ Solar-powered WisMesh Repeaters extend the range of Meshtastic networks
RAKWireless has launched two solar-powered Meshtastic range expanders/repeaters: the WisMesh Repeater with a larger battery and external solar panel, and the WisMesh Repeater Mini with a more compact design with an integrated solar panel Meshtastic open-source firmware allows LoRa nodes to be used for off-grid messaging, GPS coordinates sharing, and more. The mesh network relies on nodes to communicate with each other and relay messages to other nodes if needed. However, this does not work reliably when nodes are too far apart or one node goes offline for whatever reason.

Arduino ☛ This machine helps to experimentally find an estimation of absolute zero
How can we ever really know anything? If you listen to the anti-science types, you might believe that we can’t. But if you get past Plato’s Allegory of the Cave, you can start identifying basic truths, through logic and experiments, on which to build upon. One important foundational building block is absolute zero.
