Why is the vision correction in VR headsets only an afterthought? - Lemmy.World

> Researchers predict that by the year 2050, about half of the world’s population will have myopia. Considering the target demographic, a significant number of potential VR users suffer from myopia already. Why are there no more VR headsets with adjustable focus? Several vendors offer replaceable lenses, or various addons to fit the glasses in, but the obvious solution used by the early cheap headsets like GearVR - adjustable distance between lenses and the display, is not being utilized for some reason. Is it a technical problem, economical problem? Are the modern lenses somehow tuned for a specific distance? [https://lemmy.world/pictrs/image/caf358bb-11af-4da1-9530-8c829ee5f098.png]

Braiins Mini Miner - BMM 100 - Lemmy.World

Ever since the interview with Lukas Seyfrid (CZ) [https://www.youtube.com/watch?v=TJUeYQy-W1Y], the chief of the hardware team, it was clear that Braiins is pivoting from the development of mining software, to building their own hardware. [https://lemmy.world/pictrs/image/7ce63a7b-8908-4752-904c-1e3a0887fb02.png] This, I believe, is the first iteration of their effort in form of a consumer product, and while it is unlikely to make you a financial return on the investment, it’s small form factor and nice anodized aluminum case can allow pretty much anyone to become familiar with the process of bitcoin mining. Or terrorize the testnet. The choice is yours. I think I might buy one, just to try the viability of a pure solar setup. HW specifications: ||| | ------------- | ------------- | | Price (pre-order) | $199.00 | | Hashrate | ~1Th/s | | Power Consumption | 40W - 55W | | Number of hashboards | 1 | | Number of ASIC chips | 4 | | Cooling Type | Active | | Noise | 40 dB | | Air outlet temperature | 40-50 °C | But really, how much would it make in a year? If we assume the current price and difficulty stays the same, the block subsidy is 3.125 BTC, median fees around 0.2212 BTC, free electricity, you’d get 0.001 BTC per 12 months, which is roughly 65 USD. A little more than 3 years to break even. It’s not going to break any records, but I’m still excited for what’s to come next.

Phoenix and Wasabi exit US market amid self-custody wallet crackdown - Lemmy.World

“Recent regulatory action against Consensys and Samourai has instilled fear among other crypto service providers operating in the United States.” - Wasabi is the main competitor to Samourai’s whirpool mixing service. The only one flying under the radar currently is Joinmarket. - Phoenix is the Lightning network wallet where users keep custody of their funds, but the channel management is outsourced to the company. The only remaining self custodial lightning wallet that remains is Breez. While this news is deeply troubling, it might push further development to more sustainable trustless self-custodial solutions in the long term.

Managed to get SOMETHING out of NOAA 19, using dipole - Lemmy.world

Everyone knows helix antenna is needed for capturing NOAA satellite images, due to circular polarization of the signal, right? As I was listening to ISS APRS repeater (with great success!), I noticed NOAA 19 would pass over me shortly. Since the dipole was already set up outside, I decided to give it a go. Software used: - GQRX to capture the audio - Gpredict to know when to start the recording, and to compensate for the doppler shift - noaa-apt to convert the audio file to an image Hardware used: - RTL-SDR.com [http://RTL-SDR.com] branded USB dongle - 3 lousy USB extension cords - “Bunny ear” retractable dipole antenna that I got in a bundle with one of the SDRs Now, there is not much to see in the image, but I sure as hell can spot some clouds there, and that’s much more than I actually expected!

Can I use the same domain name for Lemmy and Mastodon? - Lemmy.world

I’d like to self-host Lemmy or kbin and mastodon. I know I could use different subdomain for each, but I’d much rather keep it short. Something tells me, however, that other instances might not be happy about it. Is it doable?
