GeekMomProjectsI got interviewed by Dale Dougherty of @makemagazine and had a chance to talk about my most recent project write up as well as other maker topics. Now I'd like to make an LED cube and orb as large as the ones in the picture appear to be!

This is what your microwave oven does to your WiFi signals in the 2.4 GHz band.

Elecia WhiteA Pacific Northwest Tree Octopus has been sighted in California, likely due to the extremely wet weather conditions this year.

@smellsofbikes sorry missed your raid invite, disappeared just when the game loaded
which team are you choosing for go tour? 😊

lucky to find a mistake before a destructive failure this week. MCP73831 is a nice lipo charge ic. learned that there are different parts in that series. one of the parameters is battery pack voltage. MCP73831T-3 charges to 4.35 V, as opposed to 4.2 V that is safe for lipo batts. why does this exist? there are "LiHV" ("high voltage") batteries for UAVs. the correct part for 4.2 V is MCP73831T-2. glad there are protection circuits to prevent over charging in some batts. #electricalengineering

Michał ParniakOur work on microwave-to-optical conversion is out on @arxiv
today! We took a six-wave mixing process and parametrically converted microwave photons into optical photons.

Continuous wideband microwave-to-optical converter based on room-temperature Rydberg atoms
The coupling of microwave and optical systems presents an immense challenge due to the natural incompatibility of energies, but potential applications range from optical interconnects for quantum computers to next-generation quantum microwave sensors, detectors or coherent imagers. Several engineered platforms have emerged that are constrained by specific conditions, such as cryogenic environments, impulse protocols, or narrowband fields. Here we employ Rydberg atoms that allow for the natural wideband coupling of optical and microwave photons even at room temperature and with the use of a modest setup. We present continuous-wave conversion of a $13.9\ \mathrm{GHz}$ field to a near-infrared optical signal using an ensemble of Rydberg atoms via a free-space six-wave mixing process, designed to minimize noise interference from any nearby frequencies. The Rydberg photonic converter exhibits an unprecedented conversion dynamic range of $57\ \mathrm{dB}$ and a wide conversion bandwidth of $16\ \mathrm{MHz}$. Using photon counting, we demonstrate the readout of photons of free-space $300\ \mathrm{K}$ thermal background radiation at $1.59\ \mathrm{nV}\mathrm{cm}^{-1}(\mathrm{rad}/\mathrm{s})^{-1/2}$ ($3.98 \ \mathrm{nV}\mathrm{cm}^{-1}\mathrm{Hz}^{-1/2}$) with the sensitivity down to $3.8\ \mathrm{K}$ of noise-equivalent temperature, allowing us to observe Hanbury Brown and Twiss interference of microwave photons.
LenoreI don’t know who need to hear this, but cleaning your glasses is a really good idea!
