So I'm setting up a new home network soon. I have my pfSense router, 1 16 port gigabit unmanaged switch and a 5 port unmanaged switch (will not need all ports, its just what I have), and 3 Engenius EAP1300 WAPs. I want to setup my network so that there are 2 networks. 1 for all home devices and 1 for IoT/guest but the IoT/guest will be WiFi only on a seperate SSID. The WAPs I have, have an option for it to be a guest network and setup its own DHCP server for the guest network but I want to have the pfSense router controlling everything and not the WAPs. I want the DHCP server and firewall rules going through the pfSense router. I was wondering how I could create a second subnet for the IoT/guest network and how to manage it all through the router. I would usually just do vlans but these are unmanaged switches. Am I asking too much and should I just go with the WAPs to do all the work?

Looking for a tablet for a relative - their main use case would be using it for WeChat video calls back to folks in HK, and I would also be setting it up for some Tuya-based IoT devices (mostly security cameras and lights at the moment). If it matters any for the latter, their ISP is Bell using the supplied HH3000 modem. I haven't really kept up with tablet hardware so I don't have any inkling on what's good or not - never really followed mobile hardware news. Any recommendations would be greatly appreciated. Currently, I saw this Samsung Galaxy Tab S6 Lite (2022 model) with average reviews that's on sale at BestBuy for $280 CAD that seems like it might be suitable? Edit: Update, I ended up going with the Tab S6 Lite and they've been happy with the product so far. -
I want to purchase an ESP32 board. In my country, for my budget range I am thinking of getting ESP32-WROOM-D development board. However, as you may know ESP has released newer versions of the board, but they are not available as of now here. Should I wait or get this board? I don't have a specific requirement for this specific board. It's something I wanted to get my hands-on now.

With the recent video about the flipper zero and just how easy it is to get into somewhat newer garage door openers i want to replace my really old garage door opener that doesn't even have a rolling code. With that i was curious outside of some obvious physical attacks that can take place what uses the most secure algorithms? It would be a really interesting idea as well for LTT to try and "hack" some of the top brands and see which one stacks up. To clarify when i say opener i mean both the remote and the actual machine that lifts the door with a belt.

So I'm not really sure if this is even the right place to post this but here goes: I'm diving into smart home/IoT stuff for the first time. I really only want Smart Bulbs (multicolor LED) and some small Smart Outlets to start, but will eventually expand to a Smart Thermostat and possibly smart speakers for certain rooms in the house. I think most other IoT devices are useless and will never be interested in Smart Fridges, Smart TVs, Smart Toasters, Smart Bidets, etc... I want to do my "Smart" stuff right. I want to make sure I start diving into home automation with properly secure hardware, if that makes sense. I've done a fair bit of research into the different standards; zigbee, z-wave etc... and know about the major offerings from Amazon, Google, etc... but am not sure what forumgoers here would recommend. Voice control would be cool to have I guess, but not absolutely necessary at this moment. Right now I'm looking for **smart lightbulbs** (LED, multicolor, ability to control via. an app), and **small smart outlets/plugs** (ability to control via. app). My questions: - Do I need (or is it smart to purchase) some sort of hub for my house? - Is it a terrible move to invest Amazon or Google hardware? I want to maintain my security, are these really as bad as they're made out to be? (Always on mics, data collecting, privacy, etc..?) - Idk, any other advice? -
Hello. This is an IoT system that I have created in separate locations to detect temperature and CO2 and ring an alarm when it reached a specific level. What improvements can be suggested? (For example: For security) Any help would be very greatly appreciated

It's not widely realized, but one of the most common cpus in use today is the good old 6504 used to power computers like the commodore 64 and apple 2 back in the 80s. Today it can be found in everything from desk fans to refrigerators to cars. https://youtu.be/yl8vPW5hydQ -
Hi guys, We are a small company based in Germany with around 20 employees. Of those 20, roughly 10 do engineering work, regarding backend, frontend, apps, PCB design, 3D design, programming and more We are currently looking for a new set of laptops for our daily work. Our most demanding apps are Altium, Solidworks, Fusion 360, JetBrains-suit and some self programmed image and video recognition algorithms. I have looked into a few brands (Dell, Razer, Alienware) but the range of laptops is too large, to have a good overview. Can anyone recommend a good laptop, preferably with an i7 or above (I know, would rather have AMD, but the software guys rather take intel), a powerful graphics card and, maybe most importantly, really good customer care ? Thank you!

Longtime electronics guy (component level troubleshooter IRL) here looking for advice. TLDR at the end. I freely admit my networking chops are...lacking a bit and am working on changing that. I have been surviving on plain Jane off the shelf level gear and prebuilts for years and finally in a position to start upgrading my setup bit by bit. Can't wait to build my first custom PC in years this coming spring. I currently have 1Gig symmetrical fiber service and plan to upgrade to the 2 gig service in my area in the near future but my current firewall just won't cut it. My current setup is the ONT -> Bitdefender box 2 -> Netgear Nighthawk router in bridge mode. Bitdefender tops out at 1GB so I plan to upgrade to a Firewalla Gold or maybe whatever their top end system is by the time I make the jump since it can handle up to 3GB. I plan to have 3 zones. All my IOT devices and my smart TV's on a dedicated IOT Wifi/Ethernet network. My personal devices on a 10 Gig internal Ethernet/Wifi network. And a guest Wifi network all segmented and separated on their own hardware. To save a bit of cost and not toss out or pass on still good gear (who in their right mind would use hand me down security hardware) I plan to use the Bitdefender box for the IOT network and the current Nighthawk for the guest network WAP. Personal network hardware I am still figuring out what I want. Yes I can hear you all yelling "TRY PFSENSE you ding dong!!!". I am lol. I may switch to that in the future but my skill level with it now is nil to non-existent and I would want to take the time to kick the tires on it a bit and make sure i am confident in my configuration before trusting it with my personal data. I also hear you all yelling "VLANs". Call me old fashioned but in my mind separate network should be separate hardware. Finally my question: What issues might I run into putting the Bitdefender box behind the other firewall? I plan to turn off most of the monitoring features of the Bitdefender box not directly associated with IOT monitoring to minimize potential conflicts. Yes I have contacted both companies for advice but have not heard anything back yet. TLDR How dumb of an idea is it to put my current Bitdefender box behind another better firewall to function as a separate IOT quarantine network? -
So I just watched the Tech Quickie “Your smart home is stupid” and realized I don’t even know where to start on securing my nascent smart home (video points out that IoT devices have notoriously bad security). I recently set up my first Unraid server and am running HomeAssistant and NodeRed on docker containers to control my hue lights and ecobee thermostat, as well as some wifi sonoff smart plugs I flashed with ESPHome firmware. Based on the TQ video it sounds like these are all easy attack vectors to my network, perhaps the ESPHome plugs the most. tal;dr I know my smart home IoT devices need securing but I don’t know where to start, especially since I need them to still be able to talk to my Unraid server and their cloud services (eg ecobee) (also, this is my first post on the forum)

I'm looking at buying an older computer to use as a server on my local network. I'd like to use it as a hub for running some custom IoT programs (MagicMirror server, voice assistant, etc.) as well as storage for some of my source code and photography. Will likely be using Docker for my IoT projects. I'm fairly new to networking in general and don't really know what specs a server would need, or if a remote server would be better. Thank you for any advice you might have! Example of a computer I'm looking at ($300): I5-3470 @ 3.2GHz GTX 650Ti 8GB RAM (guessing DDR3) 120 GB SSD + 500GB HDD -
Recently I have really gotten into smart devices e.i. Wyze switches, "outlets", bulbs cameras etc. The question is, what's the best way to have all of these devices connected with out them taking up all my bandwidth? Do I connect them all to a separate Wireless router? Should I upgrade my router to a wifi6 router? Should I abandon Wyze and go with a different brand that connects to its own hub?

I'm overdue for a new home desktop build but have slowly been moving my home services into the cloud, I've picked up a few smart speakers, a smart TV, I've got a half dozen subscriptions to various streaming services, including one for GeForce Now. And so it's becoming harder and harder for me to justify an expensive heavy duty can do everything rig, when I seem to slowly be accumulating lots and lots of extremely cheap can do something specific rigs. Amazon hit me with a targeted ad for these microcomputers from MeLE MeLE Mini PC Fanless Windows 11 Pro Portable Desktop Micro Computer Stick And MeLE Mini PC Quieter2Q Fanless Windows 11 Pro Portable Desktop Micro Computer It got me thinking maybe I'm not overdue for a bulky brand new home built rig. But maybe I might be at a point in my life where a dedicated do everything rig is a bit "old school". I'm eyeing the ones with the slightly larger form factor for mounting onto the back of the Smart TV, and used for most home requirements (printing, emails, even gaming through GeForce Now, office via Gsuite) and I could just toss out the old desktop and clear up a desk in the home office that isn't filled with keyboards, mice, monitors, headphones, the whole shebang. Keep it clean for my work laptops, and as a place I can sit down and fill out paper forms occasionally. Does anyone else have any experience with these things? Do they work as well as you'd hope with online only/first services? Or do they lag and stutter and thermal throttle like crazy with 4K video streaming and stuff? Are they priced right for what you get from them? Or are heavy duty do everything rigs still the way to go for just a little while longer? -
I'm wanting to know how much power is sent to the Power LED on the front of ATX cases. I want to control the power LED on my case with an Arduino, but I'm not sure how much power is sent to those LEDs. Is it 3.3V and the power LED board adds a resistor or do I need to add a resistor on the way out? Full Story I'm building my own SAS Expander box. This is a system with a single SAS Expander card, PSU, and a bunch of drives. No motherboard. To control powering the case, I'm going to use an ESP8266. It's similar to an Arduino and even works if I flash it with C code from the Arduino IDE. The 24-pin ATX connector provides 5V when in standby; the exact kind of power that devices like the ESP8266 use. With a relay and some code, I've already set it up so the ESP8266 can power on and off the PSU, but I'm missing the LED. Since I know the state of the PSU (as I'm controlling the relay), I can also output power to the LED like a regular motherboard. But doing so requires knowing how much power I need to send the case's power LED. -
I need to buy a PC for my work that I will be setting up to run an automated manufacturing cell. The PC will run LabView to control a couple of physical processes as well as saving test results to a DB and communicating with a bunch of test equipment. We are going to run computer vision on it, but LabView's computer vision DOES NOT take advantage of a GPU and doesn't benefit much from multi-threading. Great. We might need to add a PCIe card in the future, but don't need one now, so a free slot is useful. Also, having 4 or more USB 3.x ports is an advantage because of the high throughput cameras we will be using. I have built my own PCs before, but never sourced a pre-built machine. We aren't really interested in much manual work to set it up, any time we can save helps us stay on budget and deliver this on time. Budget (including currency): $4000 (USD) Country: USA Games, programs or workloads that it will be used for: Computer Vision (non-GPU), Measurement, DB read/write, Peripheral control (printer, barcorde scanner, etc) , robot programming Other details: Turns out the below mobo only supports M.2 22x42 and they don't have any rugged NVMe drives of that size to supply it with . SSD does have DRAM cache at least. https://www.onlogic.com/mc850-54/?configuration=2c5c647d33267e8e4e77efef696bbd49 Does anyone see any issues with the configuration at the link above? Any weird bottlenecks I might not have noticed? We'll probably be getting the Win10 IoT Enterprise OS . I think it's just WIn10 without the bloat? (Win 9 video anyone?) Processor is Xeon E-2176G with PassMark single-threaded performance of 2714. Couldn't find much better from typical supplier sites, is it worth trying for something higher? We have the budget. -
So Linus did that showcase of the windows embedded version customised to be actually awesome. Windows 10 IoT Enterprise is the equivalent of previous embedded versions. Is it possible to do something with this where is optimised as a workstation / gaming machine but without all the bloat, advertising and just general Microsoft insanity? I know i could just spin up a VM out to to run as a DC and perhaps an SCCM controller to handle it all myself, but the maintenance required compared to using OTA updates makes this an undesirable option. Anyone got any thoughts for this?

I know that Luke reviewed the Joule by Chef Steps and Linus reviewed the iRobot Roomba years ago, what about a thread for Internet of Things like smart thermostats, smart locks, smart weighing scales, programmable NFC chips, even DIY IoT using Raspberry Pi, etc.

Source: https://www.theverge.com/circuitbreaker/2017/5/30/15713394/intel-compute-card-pocket-pc-computex-2017-lg-dell-lenovo Looks like there will be 4 variants, all passively cooled with no word on price. Interesting product, they seem to be aiming it as a reference device for manufacturers. I'd be interested in the modularity concept where these slide in a 'Laptop' dock and a 'Desktop' dock. Perhaps even a tablet of mobile dock?

Hajime -- Possibly the Most Advanced IoT Botnet To Date
N3v3r3nding_N3wb posted a topic in Tech News
Hajime is a very advanced botnet that infects Internet of Things devices to (supposedly) protect the device from other infectious botnets. The next part is very detailed, so read the article if you want in-depth info. For the purposes of my summary, I'm going to do a very high-level overview. Hajime is at the very forefront of botnet technology. Whoever created it is very talented. Hopefully, this guy is really just wanting to do good, not just shutting out competition and planning a future takeover of infected devices. Also, the IoT industry better step up their game. It shouldn't be up to vigilantes to plug their security holes. Source: arstechnica.com/security/2017/04/a-vigilante-is-putting-huge-amount-of-work-into-infecting-iot-devices/- 10 replies

Between this and the wireless power transmission thing. It looks like Disney is coming up with some interesting ideas. I for one look forward to augmented reality contact lenses that are powered and transmit data without the need of a battery stuck to the eyeball. How would you want to see this tech used?

I feel the new amazon echo show could've been a much more sleeker and beautiful device then a box with large bezels and a chunky body. if the product is going to be show cased in your homes of 2017 it atleast looks like it's from 2017. your thoughts below. -
I think it would be a great idea to introduce some of the key technologies and products in any of the LTT series ( Tech quickie may be ? ) Here are few suggestions - 1)Raspberry pi - https://www.raspberrypi.org/ 2)Arduino - http://arduino.cc/ 3)NodeMCU - http://www.nodemcu.com/index_en.html 4)XBee = https://www.digi.com/lp/xbee

This new DDOS appears to be affecting different sites to the first as they appear to be striking a different part of Dyn's network. Level 3 and Cloudflare are seeing lots of errors in websites including Github and Playstation Network. Source: Ars Technica - Double-dip Internet-of-Things botnet attack felt across the Internet So far, github seems to be fine for me in the UK and I haven't seen any real problems, so this could be a more focused attack. But I think the headache caused by IoT devices' poor security is going to continue to snowball. And it's been used to try and silence security researchers in the past who stumble onto criminal uses for vulnerabilities. -

Sources: Greenpeace, Engadget, Bitcoin, Github (Samsung), Motherboard So Samsung got slammed by Greenpeace but instead of whining and calling Greenpeace fake news, they acted like adults and showcased the ways to repurpose old Galaxy smartphones as show from their Github account. Samsung said that recycling will just produce more waste and more costs when breaking down an old smartphone so they instead encourage re-purposing which they call "Upcycling". Together in partnership with iFixit, they encourage owners of older Samsung phones to use them as IoT devices like a fish tank monitor using an old Galaxy S3, smart pet bowl, an arcade gaming console, and other new ways. One crazy DIY is that it can be used for Bitcoin mining when Samsung strung 40 Galaxy S5's and as it turns out, it can be more efficient in mining than a desktop PC according to Samsung. So they compared the performance of a Galaxy S5 vs an Intel core 17-2600 but unfortunately, I can't find any tests results of these chips that uses the same benchmark and I'm skeptical if an ARM chip like the Snapdragon 801 used by the GS5 is faster than a Sandy Bridge locked i7. Personally I have a bad experience with the Snapdragon 801 because my old LG G3 is constantly thermal throttling but it's probably because it has to power a QHD resolution. Also, wouldn't collecting 40 pieces of old Samsung phones be more cumbersome than just building a dedicated PC for mining? Nonetheless it's a great initiative from Samsung and I hope other companies follow the suit. To be honest, I don't think Apple is following Samsung's steps since they don't want people hacking iOS to do crazy things like DIY IoT and I don't think the jailbreaking community is interested as many of them just submit bugs to Apple and get paid. I was thinking of re-purposing my old Galaxy Note 2 but the wifi no longer works at this moment and it's having awful screen burn in and whites are becoming yellow.

I wonder if @LinusTech is still using his iRobot Roomba that he reviewed back in February 2015 or if he'll continue using his. Source: The Next Web This is a blatant invasion of privacy. I mean tracking your floor plan and giving off the data to other companies to target you ads? I get why Apple or Amazon would be interested with a house floor plan. Apple has their HomeKit API for home automation like telling the Roomba to turn itself on during the weekends to clean rooms and charge itself automatically. With Amazon it's kinda obvious what they would do with it, sell you ads about household cleaning chemicals perhaps or others. But Facebook? Then knowing your floor plan is kinda creepy. I can't really comment on the Roomba itself since I don't own one and I'm perfectly fine with just a 600W vacuum cleaner or even just a broom for under the bed cleaning.
