It also comes in both black and white. You can buy one here. Another slightly more expensive option is the Jelly Comb Universal Back-lit keyboard. It retails for 20$, has ...

You need a small dongle that adds Bluetooth capability to your computer. I recommend something small like the AZiO Micro Bluetooth Adapter. This device is under $15 on Newegg. This device plugs into a USB port and enables Bluetooth communications with various devices via Bluetooth (speakers, printers, keyboards/mice, phones, and more). After installation ...

Having done many ERP integrations in warehouses and retail, there was pretty much one wireless barcode scanner that stood out and that was Symbol (now Zebra). They do make a Bluetooth scanner - DS6878SR and given your (increased) budget this should work nicely. Personally, I wouldn't go for the smaller name scanners. Symbol is an industry standard and ...

You can use KVM over IP for that purpose. You just need to connect your PC and your desk with ethernet cable. It's not so cheap and has some limitations for screen resolution, but maybe it can solve your problem. You can find examples of this devices here. Here is another wireless option Wireless Extender for HDMI.

I've been using a Plantronics Savi 700 Series for the past few years. It: Is way over budget at $400. I got this as a gift through a fortunate series of events. I'm definitely open to other recommendations of cheaper products. Connects to my MacBook through USB (the cord goes from the base to the laptop) The headset itself is wireless, and has range ...

I use a Jabra Speak 510, very good sound quality, can do much more than just speaker but a little expensive (about 100€) Edit for details : battery YES, autonomy more thant 10 hours, USB and jack 3.5mm port Size : round, diameter about 10cm for 2.5cm height Link : http://www.jabra.co.uk/business/speakerphones/jabra-speak-series/jabra-speak-510

I recommend the Juice Bar portable speakers. I've had one of these for about half a year, and I've been very happy with the quality of both the build and the audio - and that's coming from a professional sound engineer! They've also got great range - I managed 20m indoors, through brick walls, and around 35-40m outdoors. They're available in a range of ...

It took me a fair bit of Web searching to find the answer. In the end, I finally hit upon the correct set of terms to enter into Google. I did a Google search for [ plantronics m70 m90 vs | comparison | difference ]. The 21st search result was an Amazon.co.uk product-description page which included the information I sought. On that page, reviewer Andrew ...

Most microcontroller boards less than $20 do not have Bluetooth/Wifi/Eth, or LCD ports. The Raspberry Pi is your best bet, but if you need something a bit cheaper with the same capabilities, I'd look at the PINE A64, Currently on pre-order. $15 gets you: -64bit Quad Core ARM A53 1.2GHz CPU -512MB DDR3 SDRAM -MicroSD Slot Supports up to 256GB -10/100 Mb ...

I bought an AeroSkull HD from Jarre Technologies that already had this feature and I remember that they called it TrueWireless Stereo. It's a proprietary technology developed by CSR, the company that makes most of the Bluetooth chips and who have previously acquired aptX. Unfortunately this particular feature is not advertised through ingredient branding, ...

I don't see a price range (and its a little pricy) but the microsoft universa1 foldable keyboard meets many of your requirements. Responsive keyboard. I.e. soft keys aren't going to suit. Its chicklet style, and the same sort of switches as the MS surface typing keyboard. Tested has a mini review that suggests it has a decent amount of travel Full/large ...

iClever keyboard seems to fit your requirements. Number row is included. To use with Android you just have to choose Fn + Q. It is lightweight (0.39lbs =~ 176.9 grams) and tri-folding which makes it perfect for travel (size: 145mm x 95mm x 15mm). To sum up: compact size keyboard spacing is not cramped aluminum body rubber feet on the bottom (for anti-...

Just buy the MX Ergo. Unfortunately, trackballs are a fairly narrow market with not a ton of demand; unsurprisingly, this means that prices aren't exactly the most competitive. Finding something cheaper than the $50 Nakabayashi mouse with Bluetooth unfortunately is a rather tall order, and unfortunately, hackey solutions like converting a wired mouse to ...

Red Bear labs has quite a few options. I have used the Blend micro and didn't encounter any problems. I am fairly certain you can change the name too. http://redbearlab.com/blendmicro/ They also have smaller/larger models

There are not many good bluetooth options available, but I've listed out a couple of the best Nolan MIC Bluetooth Wireless Microphone - 64$ Bluetooth connectivity Range - 100ft(30m) Battery life - 6hr(moderate usage) Good customer reviews If you can slightly bump up your price barrier then, Sony ECMAW4 Wireless Microphone - 150$ (can get it for a lot ...

I've not tried these personally - and as with any headphones, its a good idea to try any headphones for fit (tight headphones cause headaches) and sound quality if possible, but it sounds like considering your fear of EMF, you might want to consider a IR based unit. IR's basically the same technology used in remote controls, is line of sight, and its ...

While I did not do much research on this because you did not have any real requirements other than replaceable batter and bluetooth. I have found this mouse on Amazon Mouse. Based on the reviews the batteries are replaceable and the mouse is rechargeable. I am not sure if it requires AA or AAA but should work for your purposes.

This was a hard one to find! This is my recommendation, the Griffin PowerMate Multi-Media Control Knob with Bluetooth Connectivity - Wirelessly control your Mac from Volume to Key Commands It has software that will let you change what the knob does. So instead of Volumn Up/Down, you will make it scroll up/down. The only reason I could see this not ...

The Ultimate Ears MEGABOOM is a really good option. Now on Amazon UK for £127.99 https://www.amazon.co.uk/dp/B00PDUE8TG Charges via typical Micro USB. Has a 3.5mm aux input But in general, it is a solid good speaker with awesome battery life and great sound. As for your USB charging question: if it uses the same connection it will usually charge with any ...

You can't, at least not on macOS. There's no high quality duplex audio Bluetooth profile, maximum what you can get is 16 kHz duplex SBC (mSBC, "Wideband speech"). It's better than SCO (8 kHz), but not dramatically. For some reason, Bluetooth SIG hasn't been interested in implementing high quality duplex audio since 2003. The only solution is available from ...

Use a Polar H7 strap which has Bluetooth Smart and use any application you like for your OS. Polar HR straps are well supported. Here is screenshot of Heart Beat Monitor from Windows 10 Store. It's not even made by Polar.

Any of the following Logitech Keyboards with their "Easy-Switch" technology will allow you to switch between multiple devices via Bluetooth. They have three buttons or a 3-way dial to switch instantly between up to three devices. I personally use the tenkeyless (TKL) Logitech K480 at work since it can switch between 3 devices and has a tray for my cell ...

Bluetooth is a proprietary technology which is managed by the Bluetooth SIG. Unlike "Wireless A/B/C/N/AC", which is the networking technology standardized by IEEE, Bluetooth is tightly managed by this group and specific patents are required when making something Bluetooth compatible. This means that the "stack", which manages to what and how a device can ...

The Raspberry Pi Zero W It's $10, comes with Bluetooth LE and Wi-Fi onboard, and can be very easily set for use with an I2C sensor. Under full load it draws a only 1.2W, but has enough horses to keep pace. Best of all, it has a massive community backing it, including a StackExchange community! The biggest drawback comes in the niche I/O choices compared to ...

You can obviously buy 2 USB bluetooth 4 le dongles. Gets power and CPU from the computer Gets power from batteries, but you need some kind of CPU. Designing your own and getting it produced will take a lot of effort and money to get a company to agree to produce said circuit. From the needlessly overpowered but easy solution department.

You might take a look at the Photive BTH3 Headphones off Amazon.com They go for just under $50. They are bluetooth, over the ear, have a built in mic and have a battery life of 12 hours (as they claim). The headphones also come with a carrying case. Hope this helps.

I think you'd have excellent luck with the Raspberry Pi A+ for ~$25. It has excellent documentation, some preexisting servo driver software, and integrated GPIO pins, which are the things you solder the controller wires from your motors to. It does NOT run a real-time environment, so stutter might occur, but for your use case that might not matter. At only $...

If you can spend up to 250 USD and if it doesn't have to be very tiny then I would recommend to look for a smartphone¹. Several apps exist, among them VLC for Android, iOS and Windows Phone. I just tried it on Android which works fine with m3u playlists (I never bothered to try until now and VLC on my Windows Phone somehow doesn't read the same file, even if ...
