High quality PCB Services https://pcbway.com In this video I’m showing you how I designed the mysterious Raspberry CryptoPi which was supposedly able to mine crypto using fancy new tech. This was just a 1st of April joke that I did but I’ll share a few secrets in this video. (This is a repost of the original Voltlog 157 published April 1st 2018.) →Here is a link to the current Raspberry PI: Amazon http://voltlog.com/y/s8qta Banggood http://voltlog.com/y/hmcjg →Support the channel via Patreon, Paypal or Bitcoin http://www.voltlog.com/donations #CryptoPi #RaspberryPi ... https://www.youtube.com/watch?v=xrIKdWR9PpU

High quality PCB Services https://pcbway.com Join me in this video where we take a closer look at the Reolink RLC-81MA Dual Lens 4K Security Camera. With its dual lens arrangement you are able to capture both a close-up zoomed image as well as a normal widescreen image at the same time from just a single camera. The onboarding process is almost entirely automatic, the app runs very smoothly on both windows and iOS but for more details and sample footage, checkout the video. →Order The Reolink RLC-81MA Here Reolink directly https://voltlog.com/y/pwt6b US Amazon https://voltlog.com/y/hfae4 DE Amazon https://voltlog.com/y/64z2i →Support the channel via Patreon, Paypal or Bitcoin http://www.voltlog.com/donations →Support the channel by clicking these links (CommissionsEarned) Aliexpress http://voltlog.com/y/kr0sa Ebay http://voltlog.com/y/jzkfp Amazon.com http://voltlog.com/y/qw4d3 Banggood.com http://voltlog.com/y/o4025 →Blog Post http://www.voltlog.com/ #Review #Reolink #RLC-81MA Welcome to a new Voltlog and today we’re taking a closer look at the Reolink RLC-81MA which is a dual Lens, dual view, 4K security camera. And at first, when Reolink reached out to me to send this product for a review I thought, this is not going to be interesting for my viewers, I don’t necessarily need an extra security camera so I was about to turn down the offer when I noticed that this camera actually has a dual lens system which allows you to view both a close-up and a wide-view of the scene and surely this is a very interesting feature that if you ever installed a security camera you wished you had. So this is a small bullet IP camera, it has PoE capability, it can record on a microsd card or an NVR or FTP server of your choice, it is IP66 waterproof rated, you get a nice ReoLink app for viewing the camera remotely, it’s got color night vision and various detection features among other things that we will review in this video. Full disclosure as always this unit was sent in for free for the purpose of this review and should you decide to order one, there will be some links in the description below and they are currently running a promotion so you can get this camera with a discount from its normal price. As you can see camera is very compact, comes with the adjustable mounting stand. On the front we notice the two lenses, two IR leds, one white light LED, this looks like the speaker for the 2way audio and on the back side we have a screw panel which hides the SD card. Connectors include caps which is nice, so we have the RJ45 Ethernet PoE connector, we have the DC 12V input if you prefer to use that and you also have a reset switch. I don’t have a Reolink NVR or any NVR for that matter so I will be inserting an SD card to record some test footage during the review process and please keep in mind that this camera only supports an sd card up to 256GB which Reolink claims can record continuously for up to 58 hours with default settings but before we continue Setting up the camera with the Reolink app was a very smooth and quick process, I mean if you already have the Reolink app installed and you already have an account with them, you just have to power the camera, and it will automatically be detected on the network in a matter of seconds. Then it will ask you to create a password for accessing the camera, a name for the camera and that’s pretty much all that’s needed. Then you can swipe left or right and you can view the two live video feeds. You can even view them both at the same time with the so-called immersive view option. This is my first time interaction with the Reolink app but it feels pretty intuitive, you have the different camera snapshots on the main screen, you can enter a particular view, you get a few controls at the top, for example you can manually sound a siren or you can manually turn on the color night vision mode which enables the white LED or you can turn on immersive view, where it shows both streams at the same time. My personal thoughts about color night vision on security cameras is that it’s super nice, but at the same time, having that white light, clearly gives the camera position away to people passing by, clearly attracts attention so I personally keep that feature turned off on my other security cameras which support it. In terms of viewing and downloading footage there are a couple of ways of doing it but to get the highest quality, you need to select the option for quality that says “clear”. As for download of footage it is best to switch to normal view, select high quality where it says “clear” then find your footage, next click download where you can once again select the start and stop of your clip which you can then download. ... https://www.youtube.com/watch?v=L_PLKHxTsww

High quality PCB Services https://pcbway.com The 10 channel thermocouple data logger is a project that I have wanted to design ever since I got the T-962 reflow oven to get a better sense of the temperature gradients happening inside the oven. The system is based on an ESP32 and it’s using 10 thermocouple interface chips (Maxim MAX31855) to read the temperature data and log to a micro sd card.
