First couple of days with my new Fuji X-A1

Last week for my name day I received a new camera, a Fuji X-A1. I am moving up from my old Canon SX30, and the difference in sensor size is mind blowing.There are several areas I am looking at primarily when using/judging a camera, and here they are, after just one weekend of playing with my new toy:

- low light shooting: I took some pictures in my basement, lights off, no flash, moving the ISO from 800 to 6400. I have to say the quality is amazing, and no hand shaking either. The image looks great even when it is taken against the window, so the natural light comes from behind the subject. Also, another picture with the subject facing at 90 degrees from the window, with natural light on one side and artificial (LED soft white 3000K light bulbs) light on the other, the camera still manages very well.

- speedy subjects in good sunlight, outside in the backyard, really nice colours and no movement blur, the camera was able to open up and go really fast, so no blur.

- video: this is a much sadder reality, video is not quite that much better, the AF in video is just as awful as before, at least in any scenes other than strong sunlight with lots of contrast. Not realy great. I am not that interested in video, but still...

Coming from a big zoom point and shoot, I have to say I mostly used AUTO, so I am sure even better results can be obtained with a bit of manual control. I definitely want to explore manual focus.

It is interesting with a 3x zoom lens, coming from a 35x zoom, I thought I'd surely miss the long side of the lens, but it was not so. The AF performance in the Canon made the long zoom (pretty much anything above 125mm equivalent) pretty useless in anything but the strongest sunlight. Plus the manual focus is completely unusable in the Canon. So I don't think I took more than 100 pictures at long zooms in 5 years. Actually, I would rather get a prime lens at around 40 or 50 mm equivalent and make this camera even more portable, I don't think I'd miss the zoom.

Natural stone veneer on a fireplace.



As I finished the mantle (see my previous post), I moved forward with my fireplace's rejuvenation. Next step - the stone. After a lot of googleing, we (ie., my wife, as she is the CDO - chief design officer...) decided on the ERTHCoverings' ledgestone in Sydney Yellow. We had some discussions on the corners - I wanted "real" corners, to give the illusion of bigger stones, and she liked the look and feel of the ERTHCoverings veneer, so we went with that.

As it was visible in the post about the mantle, I've already covered the fireplace, and the wall above it, in 1/4 OSB. I don't know exactly what I was thinking... I wanted to staple metal lath to it and then PL Premium the stones through the lath, I guess. That I don't think would have worked.

A much better and easier way to do it is to PL Premium the stones directly to the OSB. As the regular PL Premium has some issues with the initial tack, I got some PL Premium Fast Grab from Lowe's.

Now the top part, flat on the wall, was relatively easier, and it only took me some 6 hours, during which I can say I learned several things - which served me well next day with the bottom part, more complex and including corners:

- do not use the same cutting wheel for too long - as its diameter decreases with use the cuts get shallower and the stone will be put through more stress when lightly hammering it to break after the cutting. I have an angle grinder with 4.5" diameter wheels, and from a $3.5 cutting wheel I could get probably some 5 or 6 big cuts, plus the grinding of the cut edges. For the whole project I used 10 wheels or so, but I should have used more... I just hope the little imperfections this caused are not easily visible in the final product;

- natural stone is very forgiving, I was able to hammer (using one of those rubber hammers) it into place here and there without problems, and even if it broke - the whole thing is built of broken pieces of stone, what difference does one more break make?

- even with the Fast Grab adhesive, pieces would slide down (at the top of the fireplace opening), so I had to support them with small screws which I screwed in just under them, one screw per piece - the adhesive will keep the pieces stuck to the wall, and the screw will keep them from sliding, so this way they stone is stuck in place until the adhesive cures.

The whole area to be covered has 45 sq ft, a rectangle of roughly 3' x 6' above the fireplace and the fireplace itself is 1'  deep, 6' wide and 4' tall with a 24" x 30" opening.

As I mentioned, I covered the fireplace with OSB first to have a flat (more or less) surface to stick the stones to. I used concrete screws for this, but the existing concrete pieces are made from a very weak concrete, so I had to be careful to not overtighten the screws. It is important here to have the boards as tight and fix as possible, but the adhesive will be a lot more forgiving with small moves than any lath and scratch coat.

In terms of materials, I used two 4' x 8' OSB boards and some 40 concrete screws, plus 18 wood screws for the top part. Also, 10 or so masonry cutting wheels - I wonder if a diamond blade would prove cheaper all in all, but at $30 I had a hard time choosing it. For the adhesive, I managed to use exactly 4 tubes of PL Premium Fast Grab, and several little screws for fixing the stone pieces, which I took out afterwards.

For tools, I used a pencil, ruler, hammer, rubber hammer, caulk gun and angle grinder. Also, a dust mask, gloves and safety glasses. For opening the adhesive tubes, an utility knife and a very long nail.


The conclusion is, just like with mantle finishing: patience wins the day. The whole thing proved to be much easier than I feared, the materials being really forgiving, but it is important to take your time and not rush. The one time when I rushed (it started raining for a bit and I was cutting stone on my uncovered desk in the backyard) I managed to break on piece of stone into small (unusable) bits. Just as with everything, what you sane in money you pay in time, but in this case the PL Premium proved to be such a better (faster, cleaner) way of achieving my goal, compared with the mess of mixing cement for the scratch coat and all that entitles.

The end result is in the picture at the top of this post, if you didn't notice it. The difference in colour temperature between the top and bottom parts comes from the light bulbs - the two bulbs that light the mantle and the top are incandescent, while the other bulbs in the room are CFL, and this makes the top part to look more red than the bottom.

Cheers.

A new mantle for my fireplace - wood finishing diy.

So, we decided to redo the basement - to some extent. The family room is the first we attacked, and the centerpiece in there is the fireplace. It is right now in the middle of its second birth, and it still has some way to go before it is ready, but this post is mainly about the wood mantle, and finishing it.

The original fireplace was as ugly as they come - all concrete, gray and huge. Now, the huge part I like - it really dominates the room. The gray concrete is the part I hate. Have a look:


Especially ugly was the mantle - two big concrete slabs on top of the thing. And the foot at the bottom was a real danger for the kids playing in that room.

So I took a big hammer to it. And this was its lowest moment:


Patching it took it to a somewhat healthier appearance.


In case you wonder, the pipe coming out of the opening is the original natural gas pipe that fed the fireplace gas insert that the previous owners installed (they converted the fireplace from wood burning to natural gas).

So, next step was to get the wood. I found a nice wood mill pretty far away in the country side - or Stouffville: Century Lumber Mill. They provided me with a good chunk of red oak - it seems oak is a very good wood for beginner wood finishers, as its open pores make the staining a breeze... That's the theory at least.


As you can see, I draped the fireplace in OSB, but that is a discussion for another day. This is the natural look of the wood, and this is how the fireplace looked like with the wood fixed in place:


For the finishing, I found this recipe:
----
This finish looks great on plainsawn red oak boards and is impossible to get straight out of a can. The red dye is incredibly strong. But the gel stain is applied without a barrier coat so it darkens both the earlywood and latewood.
1. Apply Trans Tint bright scarlet to the bare wood and let it dry.
2. Apply Minwax jet black mahogany gel stain.
3. Seal with wax-free shellac and scuff-sand when dry.
4. Apply a topcoat of your choice.
----
You can find it here, if you are curious.

Any way, the funny thing had been the way I did not use any of the originally suggested materials in the recipe...

I started by sanding the pieces. I started with #120 sandpaper and finished with #220. Now at the end I realize I did not take this sanding far enough - I can still see some saw marks in the wood - I should have sanded much more vigorously.

Even though the opinions are split - some/many say that the open pores of the oak don't require a conditioner - I decided to include it, so first step was brushing in the conditioner. As the first stain was to be water based, I picked a water based conditioner.

Now, I couldn't find the bright scarlet Trans Tint dye, or at least couldn't get it at a reasonable price (could have got it, but shipping from the States was a killer), so I found something called ColorFX dye and I thought "red" was looking rather close on their website to what I thought "bright scarlet" was meant to be (in the recipe). The site was shipping from Canada, so the final price was somewhat more palatable.

Once I receive the package I thought the colour matched my expectations. Of course I tried it first on a spare piece of wood from the same piece (the wood mill gave me the cut ends as well, after all they charged me for the whole piece they cut the final pieces from, at the dimensions I requested). I didn't bother taking photos of the trial runs so use your imagination...

So here is the red oak stain with the red dye dissolved in water based clear tint base.


Once the stain dried it actually got an orange tint, but I have to say at the first look (freshly laid on the wood) it looked a definite Ferrari red... It did give my wife a bit of a scare.

The next step did not use the stain mentioned in the original recipe either. I was not able to find the black mahogany gel stain (even Minwax's web site did not mention this particular shade, so maybe they stopped making it?). So I compromised. In my trial pieces I used three colours: red mahogany, espresso, and finally, when I seemed unable to get the darkness I wanted, ebony. This last one seemed to make the cut, so I put 2 layers of it on the mantle, allowing 24 hours for drying. No scuff sanding or anything. Here is the stained wood:


Well, not really, but I did manage to give my wife a second scare...

This is after I wiped it and the stain dried:


The colour was what I wanted, but it looked quite lifeless and shallow. The next layer would fix that - hopefully.

At this step I was supposed to put on a coat of wax free shellac. Well, I didn't. Once, I could not find it at Home Depot - well, it didn't really matter, I could have ordered it from somewhere. However, I read here and there that polyurethane does not work well over shellac. As poly seemed as a given for the finish at this point, I skipped the shellac. Polyu is supposed to be a sealant by itself. so the shellac was not needed - supposedly. As I will never know what look I could have got using the shellac under the poly, I am not missing anything.

Well, the recipe called for a finish of my choice - at least I didn't have to find a substitute... So I googled some more and it seems most people in the know agree polyurethane is the easiest finishing product to work with - however some seem to think you pay in look and feel what you get in ease of handling. Well, I was not about to complain about that on my first wood finishing project. So, polyurethane was in.

I applied three coats of poly at 24 hours intervals to let them dry. Plus some very light scuffing before applying coats two and three, using sandpaper #400. Here is the result:


I have to say it looks as good as I hoped it would... As of right now it is still quite smelly, so the poly is still curing. I hope in about a week or so it will be cured (it is in the basement and it is just next to the furnace, so the air is dry and the temperature is constant and quite warm). At that point I will give it a good polish with wax, and edit this post with another picture.

The idea is to have stone veneer applied on the fireplace itself and also above it on the wall in between the two oak poles. We will see how that goes...


As it is easily visible, this has been a Minwax shoppe - the thing is, I have a Home Depot at about 3 minutes driving time from home, so it is really easy to jump in the car and get there and back. And Minwax seems to be the brand they carry most. It easy to work with and it did the job well.

If there was one lesson learned after all this, is this: the one key skill in wood finishing is patience. You don't need to be handy or smart or anything. The materials available are extremely forgiving. The only thing that is really critical is to allow the coats to dry well before applying anything on top.

A week later: I did the waxing after a week and I have to say I had a hard time trying to find the meaningful difference... I used the cheese cloth to apply the wax and a  cotton painter rag to buff it ten minutes later. The only thing I can say with certitude is that there is a definitive feeling when moving my palm on top of the mantle, my hand slides less easily. Not much in the visible range, though. Here is the last picture, after the buffing:

WiFi Roaming

About a month ago I bought a new router, draftN this time, to speed up my network and to add a shared USB port. It worked rather less than well, and as it stands it doesn't really reach as far as I wanted in terms of features. On the USB port I attached an 1T external hard drive, and it works fine, but the speed is horrendous, which I expected. The bad thing is that it is absolutely incompatible with anything you can imagine, so the only way to get stuff out of it is to copy it somewhere else - disconnect the drive from the router's USB port and nobody will be able to read it...

Well, I moved the old G router to the living room, where the connection strength was really bad, and I decided to try to set up a WiFi roaming (meaning the device(s) would transparently and automatically move from one AP to the other as I moved through the house). It's been an interesting experience and almost fully successful.

The setup of the APs was rather simple. as my DSL modem holds all the routing functions (firewall, router, DHCP,...) I only use the WiFi routers as APs. All I had to do was to set them both up identically - same SSID, security settings and the such. Easy peasy.

My wife's netbook seemed to work rather well, roaming form one AP to the other without problems. But my phone didn't want to. As both APs manage to maintain at least a trace of a signal in all corners of the house, the phone kept its connection to first AP it connected to even in places where the other AP provided a much stronger signal. It seems Android doesn't have native WiFi roaming - this is 4.1 I'm talking about. However, some googling unearthed a small app called Best WiFi that supposedly solved exactly this problem: at a (user set) level of the signal, it forces the device to reconnect to the strongest AP available. I installed it, set it up and everything seemed to work fine.

Now comes the "almost" part.. It seems to work fine when I connect first to the new router in the basement and then I move to the living room - it transfers immediately to the old G router. However, when I head back downstairs, it takes a long time and it keeps reconnecting again and again at the old G router until at some point (after I get bored watching it going up and down) it finally connects to the new router. I only have a couple of ideas about the root cause, and I am really in no hurry to test them (considering I have a week left until my big overseas holiday...). First, the old router is on channel 2 and the new one on 8, so maybe it tries to connect first to the first/lowest channel it finds. Second, the signal strength the old router provides at the new router's location (den in the basement) is way better than the signal strength the new one provides in the old one's location (living room), so maybe the phone still sees the old router and keeps at it... I'll probably switch the channels at some point to see what happens... but I'm in not hurry for now.

The droid is here!

Earlier in the month I was as excited as the next guy about Google's new little toy, the Nexus 7 tablet. I fiddled for a while and then finally I gave in and went as far as (pre-)ordering it from NCIX - it showed "backorder", and it never changed...

In the meantime I noticed (RFD forums be blessed! - that's Red Flag Deals for the uninitiated) the carrier I am stuck with for another year (Telus) had a reasonably nice promo: a refurbished (aka refreshed in Telus parlance /haha/) Samsung Google Nexus S for free with a "one year commitment on any plan." Sounds good. The small print? New activations only. So after a while (and talks with various people, and listening to a lot of music at phone quality...) I had to give up and admit that I had to get a new number if I wanted that little piece of high tech - which I did. I went on the site, got the cheapest plan ($25/mo) and got it this past Monday. The sucky part was that my old phone had a $20/mo plan... extra $5/mo. But all is not that bad. I noticed the new $25 plan has the CID included (for which the $20 plan required an add-on worth $8/mo!!!). I never bothered, but my wife had it, so I called and got her the same $25 plan, which means we are saving $3 this way - almost pays for my increase... Plus I got CID, too.

Going back to Nexus 7, once I got my new cell phone, I called Telus and cancelled my old phone, then called NCIX and canceled my Nexus 7 order (which was still waiting stock...) So no 7" tablet for me... yet!
I also upgraded the phone to 4.1.1 JB - it came with some 2.3.1 or so.

And it blew my mind away. The JB Android is amazing. The phone is also (almost) amazing. Almost is here because the battery is awfully undersized - on a full charge and with all networking turned off, playing games and watching movies will kill the battery in 3 hours... I disabled the data over mobile networks (for which the big RoBeLus guys charge an arm and a leg) and with wifi only it is amazing... Did I tell you it is amazing? Well, it is. The screen, the video performance, games, the availability of free apps, I love them all.

BTW, BB is dead. I was growing to hate it more and more over the past 2 years, but now I *know* it. And it is not the hardware that is sinking it, but the software. It sucks big time.

I am now contemplating my next moves: first I plan to root the phone, and then unlock it, sometime in the nest year as I am still tied to Telus for another 12 months. Which doesn't really matter as my wife still has 12 month on her contract anyway - and we have both phones on the same account for the free "family calling" feature. Plus try the USB OTG thing. Get a keyboard? First I'll have to get a case of some sort.

Now I need a NAS...

After several days with it, I think this phone has two technical weaknesses: the battery which is undersized - probably one three times the size would make the phone really unwieldy - and the wifi sensibility - this one is quite bad, I compared it with my wife's netbook (an Acer Aspire One some two years old) and the Nexus drops the connection in places the netbook has no problems connecting. It is rather annoying not to have a stable connection in your own livingroom... BTW, the access point is an old WRT54G from Cisco hidden in the basement.

And the lesson learnt: subscribe to RFD forums (especially the Hot Deals and the Latest Deals)!

SSD Action

I found a nice offer this past Friday for a nice little SSD, the OCZ Agility 3 120GB at $85, plus a mail in rebate of $15, will see how that goes, I posted the form today... Anyhow, I got my little SSD and I was faced with two problems: one, how to port Windows 7 from my current SSD (a 64 GB Kingston V100) onto the new one, and second, how to port my living room OS, Windows XP, from its former host - an 120GB "traditional" hard drive, onto the Kingston SSD.

The first step proved to be rather easy both to research and to actually perform - the nice Windows 7 feature called System Image took care of all the details - I imaged my boot SSD on my secondary 1TB hard rive, then replaced the SSDs, booted from the Windows 7 installation CD and told it to "repair" the system using the system image just created. Really a let down in terms of dramatic build-up. The whole action took maybe 30 minutes including screwing the screws.

The second part proved to be a bit more challenging. First, the ubiquitous Google - I tried "system image Windows XP" and found another gem for my little bijoux collection. It is called XXClone, and comes with a freeware version, with very limited functionality. Basically, the only feature it has in the freeware version is... you guessed, cloning one hard drive onto another. Talk about lack of drama.No tension, no angst... A bit of action, though, as I had to download the little thingy, install it on my htpc and let it do its part, after I connected the SSD (I had to get a SATA data cable out of cold storage... more action!). It took about an hour to move all the data from the old hard drive to the SSD, then 2 seconds to make it bootable, and voilĂ !  More screws to screw, and the whole thing took maybe two hours or so.

That was so much easier that I first feared. While I knew Windows 7 has that nice backup feature that can handle replacing the system hard drive with no pain only gain, it was the Windows XP one that gave me the shivers for a little while.

In the end, one word: XXClone!

The Harper year

I found yesterday a very nice article about the first year of Conservative majority in Canada - I thoroughly recommend it: Harper Unbound in The Globe and Mail.
