fixed : new hi-res icon for Scanmarker.app

Question :

I have recently bought an Scanmarker Air scanner-pen. Seems like a great device. I’ve also installed the macOS-app. Strange thing is that the app’s icon is very pixelated.

How can I change that ?

 

Answer :

Scanmarker has released new colorful versions of the Scanmarker Air pen that can be bought here. It’s a great device for :

  • reading out written text from a book (very handy for anyone having dyslexia)
  • translating text on-the-fly
  • scanning text (or just portions of text) from textbooks

The official icon of the current Scanmarker app for macOS is still a 32x32pixels icon, which is a very old that shouldn’t be used in macOS (where 1024x1024pixels icons are standard).

Simplest way to fix this is to download an appropriate icon of higher resolution and paste that onto the app. Here’s how to :

  • either download my custom made 1024×1024 icon here :
  • or download the original icon here (still fuzzy since it is a 300x300pixels icon enlarged to OSX-native 152x152pixels) :  Scanmarker Android app icon
  • or download the icon of the iOS app here : ScanmarkerAir iOS icon
  • or download the diap desktop icon here :ScanmarkerAir OSX icon
  • after downloading your preferred icon, do this :
  • select the Scanmarker app in your Applications folder
  • press [CMD]+[I] to open the “Info” popup menu
  • then click on the icon (top left) and a blue outline will open around it
  • then open the file (with the icon as a picture) you’ve just downloaded in Preview
  • in Preview press [CMD]+[A] to select the entire image
  • then return to the Info-popup window, and press [CMD]+[V] to paste the new icon
  • now your Scanmarker app has a better looking icon
  • to make sure it also shows on the Desktop, delete the old Scanmarker alias from the Dock, then open the Scanmarker app again and right-click on it’s icon in the Dock and select “Keep in Dock” from the popup menu

That’s it !

enjoy 😉

fixed : Logitech Craft keyboard not recognized during macOS 10.14 Mojave startup

Question :

I have bought this great Logitech Craft keyboard and it works perfectly. I love it. With it’s backlit keys, it’s programmable crown-dial, it’s USB-C charging, it’s multiple device-switching and it’s very responsive keyboard keys, it’s a joy to work with and a very interesting alternative for Apple’s own Extended Magic Keyboard at roughly the same price point if you shop around.

The only problem is : when I start up (or restart) my Mac, the keyboard isn’t recognized so I can’t type my password to unlock my Mac…

When using the Carft keyboard with my MacBook Pro that isn’t a huge problem, since I can just open the MacBook Pro and use the built-in keyboard to bypass this, but with my new Mac mini… I’m stuck…

The only option I could come up with is to keep an old USB-keyboard connected to my Mac mini and just use it for loggin in only… but that’s not a very tempting solution…

Isn’t there any alternative solution ?

 

Answer :

Yes, there is… there are actually 3 alternative solutions (option 3 is the most versatile in my opinion) :

  1. use your Apple Watch to login on macOS Mojave (of course, this won’t work if you don’t wear an Apple Watch…)
  2. use the on-screen keyboard during login (the so called Accessibility Keyboard that you can use when only your mouse or touchpad is recognized)
  3. use Logitech’s Unifying Receiver (the 2.4GHz RF-connection USB-plug that came with your Craft keyboard)

1. To enable your Apple Watch to unlock macOS Mojave, do this :

  • go to Settings.app
  • click on “Security & Privacy”
  • in the window that opens, click on the “General”-tab
  • put a check mark at  “Allow your Apple Watch to unlock your Mac”
  • then use the “<“-button to go back to the main Settings screen
  • then exit Settings.app (by clicking on the red dot top left)
  • now, you’ll only need to make sure you wear your Apple Watch and have it unlocked before you try to login on your Mac… (this seems trivial, but turns out to be complicated from time to time…)

2. To enable the on-screen keyboard during login, do this :

  • go to Settings.app
  • click on “Users & Groups”
  • in the window that opens, click on “Login Options”
  • then, click on the “Accessibility Options”-button
  • in the window that opens, put a check mark at “Accessibility Keyboard” and click the “Apply”-button
  • then use the “<“-button to go back to the main Settings screen
  • then exit Settings.app (by clicking on the red dot top left)

3. To setup the connection with your Craft keyboard using the “Unifying Adapter”, do this :

  • find the Unifying Receiver (the USB-plug) that came with your Craft keyboard… it might still be in the original box… if you can’t find it, you can get a new one here or at Logitech (Logitech charges $15 or €13 plus shipping for it)
  • plug the Unifying Receiver in one of the USB-ports on your Mac (or in a USB-port of a USB-hub that is connected to your Mac)
  • go to Settings.app
  • click on “Bluetooth”
  • in the “Devices”-list click on the Craft keyboard, the non the X-marked dot that appears on the right side of it (to un-pair the Craft keyboard from your Mac)
  • then go to https://support.logitech.com/en_us/downloads and download the latest version of the Logitech Options software
  • install the Logitech Options software on your Mac
  • then, go to Logitech Options.app and follow the directions to pair your Craft keyboard to your Unifying Receiver
  • note that in macOS 10.14 Mojave you will need to also allow Logitech Options.app in the Privacy settings, to do so do this :
    • go to Settings.app
    • click on “Security & Privacy”
    • in the window that opens, click on the “Privacy”-tab
    • then, click on “Accessibility” in the list on the left
    • then, put a check mark at “Logitech Options Deamon” on the right
    • then use the “<“-button to go back to the main Settings screen
    • then exit Settings.app (by clicking on the red dot top left)

That’s it !

fixed : new iPhone can’t connect to Polar heart band

Question :

On my previous iPhone I had several heart function registration apps that work with my Polar H10 band. Now I have replaced my iPhone for a newer one, these same apps on my new iPhone can’t connect to the Polar band. They don’t even list it as an available Bluetooth device.

What can I do to fix this ?

 

Answer :

To reconnect your Polar band to your new iPhone, in case the Polar band is not detected, do this :

  • attach the Polar band on your body (after moistening sensor strips)
  • open the app that couldn’t pair with your Polar band because it couldn’t find it
  • try to pair again
  • if the app can find your Polar band, let them pair
  • if the app can’t detect your Polar band, continue with the following
  • open the Polar Beat app (if you need to download it first, you can do that here)
  • if you don’t have an account yet, you can click “Continue” instead of “Sign in”
  • then click “Settings”
  • then click “HR sensor”
  • then choose ‘new device’
  • see the Polar band appear
  • click on it’s icon
  • save this new setting
  • open the other app that couldn’t find your Polar band
  • let it search for new devices
  • now see your Polar band appear in the list
  • then pair them

that’s it !

fixed : need to replace batteries in new Magic Mouse

Question :

I am using my friends iMac at this moment, and I get a message “Mouse Batteries Very Low – Replace or recharge the batteries soon.”. So I turned this Magic Mouse upside-down and now it turns out that the bottom side is different from my own Magic Mouse… I can’t find the lid to open the Magic Mouse and get the empty batteries out…

What is wrong ?

 

Answer :

The Magic Mouse you have yourself is a 1st generation Magic Mouse that does have a battery compartment with normal AA-type (rechargeable) batteries in it.

The Magic Mouse you are holding now is a Magic Mouse 2 (2nd generation) that has a rechargeable battery pack built-in. There is no battery compartment you can open, there is no lid. You just have to take out the Lighting cable from the iMac-keyboard (or get a Lightning-cable equipped USB-charger from your iPhone or iPad) and plug it into the small oblong hole in the bottom of the Mighty Mouse 2 and it’ll start recharging.

That’s it.

fixed : budget friendly OBD2 dongle for my car

Question :

My car’s on-board computer system sometimes gives unexplained, rather random, error messages. Up until now, I went to the dealer garage to have my car’s on-board computer system be analyzed and reset. Recently I heard that I could buy an OBD2-dongle myself and read and erase error messages myself. That would be a real time (and money) saver.

Is there any budget-friendly OBD2-dongle that I can use with my iPhone ?

 

Answer :

Yes there are several OBD2-dongles available that can do the job for you. Just make sure that you keep these things in mind when choosing one :

  • make sure the OBD2-dongle is compatible with iOS (as some are only compatible with PCs or Android-devices)
  • make sure the OBD2-dongle’s connection is over Bluetooth LowEnergy a.k.a. BLE (since that’s the only way to be able to connect your iPhone to your regular WiFi-network (internet) and to the OBD2-dongle at the same time)
  • make sure the OBD2-dongle is based on the original ELM327 chip (most cheap Chinese knock-offs are based on problematic, unreliable clone chips)
  • make sure the OBD2-dongle is compatible with the software you are planning to use with it (not every OBD2-app connects equally good to every OBD2-dongle & if you need to erase the error messages, most FREE versions won’t do so you will usually need the Pro version)

One of the cheapest reliable OBD2-dongles I’ve found is the TONWON OBDII Pro Bluetooth BLE4.0 for about €26,- ;

buy it on Amazon.com, Amazon.co.uk or Amazon.de

And do not forget to get an accompanying iOS-app :

most interesting for the budget-wary is Car Scanner ELM OBD2 Pro for about €5,50

(or the more expensive OBD Fusion at about €11,- or even the €20,- OBD AutoDoctor that even has an additional Mac-version)

…so buying into this DIY-solution is cheaper than having your car’s on-board computer system reset only once !

fixed : where’s the Bluetooth on my JVC KW-XR816 car stereo

Question :

I want to connect my iPhone to my JVC KW-XR816 car stereo using Bluetooth, but I can’t find the Bluetooth option in the settings menu…

What is wrong ?

 

Answer :

The problem you are encountering is probably caused by the fact that the JVC KW-XR816 car stereo doesn’t have the Bluetooth-receiver built-in… it is different from other car stereos in the respect that the Bluetooth-receiver comes as a separate USB-dongle in the product packaging…

So, find the USB-dongle in the product packaging and stick it into the USB-port on the front of the JVC KW-XR816 car stereo (or, if you slide out the entire JVC KW-XR816, you will see there’s an extra USB-port on the back of the car stereo that’s even more suited for the Bluetooth-dongle). And if the Bluetooth-dongle is plugged-in, the Bluetooth option will ‘magically’ appear in the settings menu…

If the Bluetooth-dongle is plugged-in, but the Bluetooth -option still isn’t showing in the setting menu, plug it out and then plug it back in and make sure it’s connected properly.

That’s it 😉

If you want to consult the full manual of the JVC KW-XR816, you can find it here :

fixed : Xiaomi Mi Band Pulse seems bricked or broken

Question :

As I was fiddling with connecting to a bluetooth speaker, the connection to my Xiaomi Mi Band Pulse suddenly vanished. Even though my iPhone can still see the Mi Band, but it says “Can’t connect to band” and on manual retry connection cannot be established due to a time-out error. In Bluetooth Preferences the Mi Band is visible, but not connected, and on manual retry I also get no connection due to a time-out error.

Is my Mi Band bricked or broken ? If not, what is the right way to reconnect my Mi Band to my iPhone ?

 

Answer :

You are probably in luck as even when your Mi Band seems bricked or broken, is most of the time just hangs and can be fixed doing a reset.

The reset & reconnect procedure in short :

  • switch-off Bluetooth
  • reset the Mi Band
  • reboot your iPhone
  • switch-on Bluetooth
  • reconnect via Bluetooth

That probably isn’t enough info, so here’s a step-by-step walk-through :

  • on your iPhone, swipe-up from the bottom of the screen to get the ‘underwater’ Settings pull-up panel
  • click on the Bluetooth-icon in a white circle, which will then turn grey, indicating Bluetooth is OFF
  • now take the sensor-pod of the Mi Band Pulse out of the bracelet and put it in the refrigerator (yes, the one in your kitchen, but not in the freezer)
  • leave it there for at least one hour (officially that should be at least 4 hours, but experience shows that only one hour will also do most of the time…)
  • first, do a reboot of your iPhone by pressing the MENU- and ON/OFF-buttons at the same time until the screen goes black and a white Apple-logo is displayed [ NOTE : for some iPhones the reboot procedure (a.k.a. “hard reset”) is slightly different ; more info can be found here ]
  • when the iPhone comes back up, type your access code to unlock your iPhone
  • then swipe-up from the bottom of the screen, and in the pull-up Settings panel, click on the Bluetooth-icon in a grey circle, which will then turen white, indicating Bluetooth is ON
  • and open the MiFit-app on your iPhone
  • then, take the Mi Band sensor-pod out of the fridge and plug it in the Mi Band-charger cable and put the USB-end into a USB power adapter (a powered USB-port will also do most of the time)
  • now be quick : only during the blinking of a LED on the Mi Band sensor-pod you have the opportunity to reconnect !
  • while the LED blinks, in the Mi Fit-app, in the Status view, click on reconnect to re-establish the Bluetooth-connection between Mi Band and iPhone
  • if all orange-collored texts are gone from the Mi Fit-app, you have successfully reconnected, if not : just unplug & replug the Mi Band sensor-pod, try again and make sure you act quickly
  • everything should now work properly ; enjoy !

If you can’t get it to work using the above procedure, just try again. And if that still doesn’t help after several tries, try these versions of the procedure, in this order :

  1. try again, without putting the Mi Band sensor-pod in the refrigerator
  2. try again, exactly as described (so including the refrigerator procedure)
  3. try again, now keeping the Mi Band sensor-pod in the fridge for at least 4 hours
  4. try again, now keeping the Mi Band sensor-pod in the fridge overnight
  5. try again, but start with deleting the MiFit-app from your iPhone, and reinstall it after reboot
  6. try again, exactly as described

You probably have things up and running by then, but if you’ve done all this and it still doesn’t work, your Mi Band sensor-pod is probably broken and you should contact your reseller for a replacement…

Good Luck & enjoy !
