Fold up desk

We have a short term need for two desks in our study.

I've made a fold up desk from some materials I had in store. It's narrow and folds flat so that it can be tucked behind a cupboard when not in use.





I'm pleased with the result and it works well.

Update:

A slight change to better suit the uneven nature of the live edge top.

Mac Illustrator keyboard shortcuts now working

 It has been many years since I last had to support a Mac so what I am about to say may not be very well informed.

I needed to setup a Wacom Intuos 5 graphics tablet on a Mac Pro desktop to use with Illustrator.

Downloading and installing the drivers for the older Wacom tablet were not difficult. It is still supported by the latest driver set.

During the install the driver installation requires some Security and Privacy settings to be enabled for the Wacom drivers.

The note says something like, enable the options for all of the Wacom apps.

That is incorrect or at least misleading.

If the Wacom Desktop Centre is allowed to intercept the keyboard, Adobe Illustrator shortcuts do not work.


The problem did not show up until trying to use some shortcuts, like 'Layer forward and back' 'Cmd [ and ]' It was luck that I remembered the various settings and suspected that one of them might have been the cause.

From the Mac Settings (Gear) icon, go to 'Security and Privacy' and then 'Keyboard'. Make sure there is NO tick next to Wacom Control Centre.

I unlock changes by selecting the Lock icon and entering a password.


For the various Wacom products, there should only be a tick next to the Wacom Tablet Driver in Input Monitoring and a tick next to the com.wacom.IOManager in Accessibility. 

Once the changes have been make I locked the preferences again.

Correcting that, fixed the keyboard shortcuts in Adobe Illustrator.

Sync Windows laptop to Synology NAS

There are, no doubt, many ways to backup your files to a NAS box. Synology specifically allows the installation of various apps. None of those are necessary if your aim is to keep a copy of all your data files on a Windows laptop.

Windows Built-In File Sync.

A long time ago, in the early days of Windows networking Microsoft included features to store the contents of the Windows users folders, on a network share.

There is little control, nor need for control, of how it does this. When you logon to your laptop and it can connect to the network share, it will carry out a bi-directional synchronisation of any folders setup to do so.

The sync., is limited by the speed of the components, such as network and disk drives but that's about it.


BACKUP the Files

Before I do anything like this I always take a copy of anything that could be affected. Things do not always go to plan.

In this case I simply copy ALL of the files to temporary folders, away from where I will be working. That could be off of the root of the C: drive or better still on to a removable disk.

If it is on the same machine I would create folders, similar to the following:
C:\Temp\DocumentsCopy
C:\Temp\PicturesCopy
C:\Temp\MusicCopy
C:\Temp\VideosCopy

When finished moving the folders to the network, and I am sure that the files are all where they should be, the temp folders can be deleted.


What Will The Built-In Sync., Do?

  • Copy every file in any specified folders to and from the NAS.
  • No user intervention, except in rare cases.
  • Keeps a copy on the computer. If it is a laptop, you can work on it wherever you are and when you return home, it will sync., any file changes.
  • It will sync., between multiple machines. If that is useful to you.

What Won't It Do?

  • It will not backup the operating system.
  • It will not backup applications.
  • It is not reliable at backing up user settings, so these instructions do not include that detail.
I have also not included setting this up to work remotely over a VPN, because I have not tried it.


What to do on the Synology

Connect to the Synology NAS using a web browser.

Setup a normal user account. I strongly recommend an additional account, not the default admin account.

Control Panel - User


If you are the main user, you could give yourself admin rights, at least for the duration of the setup.

Control Panel - File Services


The core requirement for Windows networking is SMB (Server Message Block.) It is probably enabled by default on the NAS box.


One thing to note is the box at the bottom that shows the Universal Naming Convention (UNC) path to the NAS box. This can be tricky to get working, so I just use the IP address.

It should work, if the following option is enabled.

Advanced TAB (not the button)


Back to the SMB/AFP/NFS TAB

If you are curious, all of the initialisms on this tab are different types of network file systems. AFP is used by Apple Mac computers and NFS is an open standard which I rarely come across being used.

SMB is widely used, including by Microsoft.

Advanced Settings BUTTON (not the tab)



I would hope that by now SMB 2 is the default and SMB 1 is disabled but worth checking. The minimum SMB protocol should be SMB 2.
The reason for this is that SMB 1 is insecure and should not be used.

Windows 10 also supports SMB 3, so if you only have Windows 10 computers you can change the Maximum SMB protocol to SMB 3.

That's all that is necessary for Windows networking and it is probably already setup for you.


What to do on the Windows computer

I find it useful to setup a Quick Access link to the file system on the NAS box. I go to it so often, especially during setup, that this saves time.

File Explorer


The IP address of my NAS box, for the sake of this example, is 192.168.1.40. If you have managed to get the UNC name to work, then you can use that instead of the IP address.

Whatever you use, type the address preceded by "\\", in to the address bar. In my case "\\192.168.1.40" Get the slashes the correct way round, the other way will take you to the internet and fail.

At this point, if it is the first time you have browsed to the NAS, you should be prompted for your Synology NAS login.


This is asking for the username and password of the account you setup on the NAS box.  This is NOT your Windows login details

Tick the box to Remember otherwise the synchronisation will be unreliable because it won't work until you login. If you tick to remember the credentials, it is all automatic.

Drag the UNC in File Explorer

Now you have logged in, drag the UNC or IP of the NAS, from the address bar in to the Quick Access list to create yourself a very convenient shortcut.

Create Folders

All being well, you should be able to navigate to your own user folder on the NAS box.


Create 4 folders under your name:

  • Documents
  • Music
  • Pictures
  • Videos

I recommend that you do not include Desktop in this list. If you are the sort of person that habitually saves to the Desktop, I would urge you to change your behaviour and use Documents, where data files are intended to be.

If you decide to do Desktop, you are on your own with that one.

There is no harm doing Downloads, as far as I know, but, in my case, I end up with a whole bunch of junk in there that would just waste performance copying to the NAS.


Enable Offline Files

This gives the option to keep a copy on the local machine, of network folders that are on the NAS box. A laptop can then be used anywhere and files sync., when returning to the home network.

Control Panel - Sync Centre


Manage offline files

Make sure offline files is enabled, if not, then press the button to enable the feature.


Change the Folder Locations to the NAS

In File Explorer in the side bar, under "This PC", one at a time, for each of the four folders we have selected, right click, go to the properties of the shortcuts in File Explorer.

Go to the Location Tab.

The image above, shows the result after the move. Prior to the move the location would be on the local hard drive.

Press the Move... button.

As all of my computers are done, I cannot reproduce the screens but what should happen is that you navigate to the corresponding folder on you NAS box, for your user account, and move.
There will be a prompt you need to accept but I can't remember what it says.

I recommend trying a folder that has the least content, just in case you need to slightly change the procedure. As you can see, there is a button to Restore Default, so you can roll this back.

Do the same for all four folders.

Always Available Offline

To keep a copy on the local machine it is necessary to set that folder to be available offline. See above to ensure that the offline files feature has been anabled.

Right clicking on the shortcut should show an option:

There should be a tick next to a heading of  'Always available offline'.

Failing that, it is available from a Tab in the properties of the shortcut.

Use the Sync now button to kick off storing a local copy.


Finished


Well, wait a while, might be a long while, if you have a lot of files.

You can follow the progress on the NAS box web interface or the full UNC path to the NAS box in file explorer.

Testing

When you think it is all finished. Create a test file in each folder, make sure it has contents, sometimes zero size files don't sync.

Make sure the files get to the NAS box. It's not instant, Windows does it in it's own time to minimise the performance impact on the machine.

Conclusion

The instructions are not fully detailed but hopefully anything I have missed is obvious when you come to do it.


Extras

Microsoft Office File Security

Microsoft Office includes security features to protect you from malicious files.
If you edit files directly on the NAS box you are likely to encounter this protection. An extra butoon in a yellow warning bar that you have to press before you can make any changes.
If you always edit files on your own computer and let the synchronisation copy the files to the NAS box then you don't need to worry about this.

If you do work directly on the NAS box file shares, the extra prompts can be annoying. The best security is to leave it enabled but I tend to turn to off.

Open Any Microsoft Office Application.
File - Options
Trust Centre

Press the button for Trust Center Settings.

Tick the option, near the bottom that Microsoft does not recommend.

Network Trusted Location

Windows, by default, will not trust network locations. It will add additional warning messages when you try to do things like, copy, rename and delete when working on files directly on a local NAS box.

If you only ever save to your machine and let Windows sync the files to the NAS box, then the following is of no benefit to you.

I have network shares directly on my NAS box, lots of them and I find all the warning messages a little tiresome. They can be avoided by setting the local network as trusted. This is done from the internet options in control panel.


Control Panel - Internet Options
Security TAB
Local Intranet
Press the Sites button.


Press the Advanced button.

In the 'Add this website...' box, type in the first part of your local network IP range and use a * for the last octet. (This is not how subnets work but if you have a more complex home network, you already know that.)

Your network may not be the same as mine. Enter your IP range.

Press the Add button.

Close and OK back to the control panel.

Hopefully that will reduce the number of warning messages for working on the network.

Restoring Windows

These instructions are not for backing up a Windows computer but they can have a part to play.

It is very difficult to create a backup of a modern Windows computer that could be restored on to another computer.

To recover from a catastrophic machine failure, the operating system needs to be installed from scratch on the new machine. The user account created, then each folder moved, as per these instructions. The files will then sync., back to the computer in their own time.

While that's happening, it is an opportunity to install the required applications on to the computer.

Worn bike drive train

 I've seen a few posts on Facebook which ask, "is my chainring worn out", "should I replace my chainring."

I have just replaced a crankset, probably beyond its expected lifespan, which shows clearly what a worn out chainring looks like.

Side by side, the new and the old. Surprisingly, that chainring was not skipping. I only looked at it because the whole drive train sounded clunky!

I am pretty sure this got to that stage quickly because the chain was worn out. I checked the chain a month or so ago but in that time, it has gone from acceptable to thoroughly useless. I blame the wet mud at this time of year.

A chain guide is the best way to check a chain and easy to use.

I was interested in looking at how a chain wears. I have heard people refer to chains as stretching. This is misleading because the components of the chain do not stretch but the pivots wear smaller allowing play. If you push and pull two links you can see and feel the movement of the links. A new chain has virtually no movement along the length of the chain.

In the case of a severely worn chain, if you pull it taught and offer it up against a new chain, you can see how much play there is.

Ring IR beam modification

Ring Security, as far as I know, do not have an infra-red beam solution for things like driveways.


It was a fairly easy job to modify a Ring door sensor to connect to a commonly available IR beam.

I'm sure I'm not the first, nor will I be the only, person to have made this modification.


The door sensors use a standard reed switch, which is just on and off. The IR beam, that I have, just connects or breaks a relay switch, so is ideal to connect in to where the reed switch would normally be.

I soldered on a pair of wires in place of the reed switch.

I used a water proof box to house the modified door sensor and ran the lead to connect it to the IR beam. Works perfectly.

Fixing squeaky bike brakes... or not

 I spent the afternoon trying to stop my rear brakes making a screeching sound when fully applied.


The usual reason suggested for the noise is contamination on the pads however, some people say it can also be caused by vibration due to the caliper being out of alignment.

I tried all the various methods that I have read about that people claim fix noisy brakes:

  • Carefully aligned the brake caliper
  • Sanded the pads on a flat surface
  • Cleaned the pads with brake cleaner
  • Soaked the pads in brake cleaner
  • Cleaned the pads with engine cleaner
  • Smeared a thin layer of copper grease on the back of the pads

In addition to the above, at each attempt, I thoroughly cleaned the disc rotor with brake cleaner and a clean paper towel.



None of those stopped the squeak.


The final solution was to replace the pads with new ones. That worked. No more noise.

My conclusion is, that the rotor is easy to clean but if the pads don't stop screeching after a quick sand and wipe over with brake cleaner, they are probably going to need to be replaced.

Bike cleaning

When did cleaning become so complicated. When I was young the only thing we had was dishwashing liquid and that was perfectly fine in a warm bucket of water with a sponge. That was despite the limitations of the paint at the time and steel frames.

Now paints are more resistant to, well..., nearly everything, plus frames are more likely to be aluminium or even carbon and yet people obsess, mainly on Facebook, about not using this or that because it's got salts in it or other stuff that might do this or that to whatever. I decided it was time to put down my opinion to counter the modern paranoia.

Don't wash the grease out of your bearings

This is one area that, I think, does need to be taken in to account. It's not easy to wash the grease out of bearings. You could do it by pouring neat degreaser in the bearings but, in my opinion, normal levels of washing are not going to be detrimental to the bearings. Using a jetwasher is a bit more of a risk, in my opinion. Directed at a bearing they could potentially force some of the grease out. I don't use one, I find our hose pressure is more than adequate to get wet mud off.



If I was to use a jet washer, I would make sure I only directed it at the bits of bike that do not have grease. Avoid the wheel hubs, bottom bracket and headset. I would also not use a jetwash on fork or rear shock seals.

For that reason, I would not use a jetwash to clean the cassette, even though I think that might be a time saver.

Cleaning the frame

Most of the time I just hose down the bike while mud is still wet and sometimes go over with a microfibre cloth. That does a fairly good job.

If mud is already caked on I'll use a detergent. I'm not fussy, I'm happy to use dishwasher liquid in warm water but I find that the pinky colour Muc-off is much less hassle because it just needs a quick spray on and wipe off.

Cleaning the cassette and drive train

This is a little more work. I'm not usually aiming for pristine but that would be the same principle with more effort.

I use a biodegradable degreaser. As far as I can tell it's just a stronger detergent. I soak the gears in this to loosen off the grub that builds up on and between them.

I scrub with a stiff brush and then a scraper to get the bulk off. From then onward I use a blunt pad saw blade to get between the sprockets and work my way round pushing out the oil soaked mud from all the holes. It's time consuming but I have not found a more effective way.

Cleaning the gears is time consuming, so I don't do this very often. I have found that most of the time, the chain pushes the mud out of the way, so as long as the gears still change properly, I tend to do no more than push off the excess grub with my fingers.

Lubricating the chain

After I clean the bike, I always oil the chain before putting it away.

I quickly dry the chain with a cloth before adding whatever oil I'm in favour of at the time.



In the winter, I tend to use Muc-Off wet lube. It's thick enough to stay on but not so thick that it picks up too much grub.

In the summer, I still prefer a wet lube. I am in England so it will still rain but I use something thinner, like TF2.

Cleaning brakes

I have disc brakes and have not had rim brakes for a very long time. I suspect that the principles of cleaning disc brakes also apply to rim brakes.

The brakes get hosed down with any normal clean which is normally enough. However, if I need to clean the brakes on their own, I will use Isopropyl Alcohol or Brake Cleaner, which is typically at least 70% Isopropyl Alcohol.

The discs are easy to wipe round with a CLEAN cloth, usually a paper towel. The pads need removing to clean those. I find cleaning the pads, less satisfactory. I'll post a separate article, at some point, on that subject.

Cleaning tyres

I don't try to make tyres look new, so I can't comment. I just wash off the mud with a hose and if I'm cleaning the frame, wash the tyres over at the end with the leftovers of the water or whatever I am using.


I ride a mountain bike, I expect it to be muddy looking most of the time.


Conclusion

I clean my bike so it is suitable for riding. I'm not after showroom shine.
