Getting rid of Facebook's annoying new ticker and adverts

Thursday 06 October 2011 at 11:37 am

This works for Mozilla Firefox or Google Chrome, however if you’re a page admin it will hide some useful links.  The process basically hides the CSS element which governs the right-hand column, so it’ll only work until Facebook does another re-write (in about 10 minutes, by previous experience).

Both browsers use the Adblock Plus extension/plug-in.  To get it go to:

Firefox or Chrome

To configure it in Firefox, click on the little ABP icon at top-right and click Preferences.  Then click Add Filter…

In the New Filter box, type facebook.com###rightCol and hit apply.  Refresh your Facebook page and hey presto!, it’s gone.

In Chrome, once you’ve added the extension, go to the spanner icon, tools, extensions the click Options for Adblock.  Click Add your own filters tab and add the same text. Job done.

As I mentioned earlier, it kills the whole column which in Page administration contains some useful stuff, so you’ll need to disable this filter temporarily to see these.

Guitar over Cat5 project 4

Sunday 17 July 2011 at 10:37 pm

Done some testing in a ‘real’ environment now, and it’s a qualified success.  It handles the FX send and return plus the channel control without a problem, even over 10m of cat5.  However the disappointment is that as soon as I add the input from the guitar it squeaks and feeds back like a bastard.  It just about copes over 1.5m but is unreliable over a longer run.  If I had any electronics knowledge at all there’d probably be an explanation.

So I will be using it live, as I hope it’ll reduce setup/breakdown times.  Pics of the final setup to follow

Actually there won't be any pics; I've had a radical rethink and gone all old-school, and I've got rid of the Vox Valvetronix and Boss pedalboard, in favour of a good old-fashioned valve (tube for American listeners) amplifier.  I've built up a nice selection - main gigging amp is a 15-watt Laney Cub 12R, perfectly loud enough for the small pub/club gigs we play, plus it now has a 1976 vintage Celestion speaker in it for lovely warm bluesiness.  I always carry a spare, which is a cheap Harley Benton GA15, although my friend and amp builder has tweaked it slightly, and it also has a Celestion speaker inside.  For bigger, posher venues I use my precious and brand new Trevinitone TT18 18-watt, hand built by my friend.  If I really want it loud, I also have a 1981 vintage Watkins (WEM) Dominator Mark4, which runs about 30 watts but has enough power to demolish small dwellings.

I just use a simple Ernie Ball volume pedal to switch between rhythm and lead sections, but otherwise plugged straight in.  It's a lot less bother!

That said, I was very happy with the Cat5 solution, and did use it for gigging for a good few months.  Gets some funny looks from those 'in the know', I can tell you.

The stage end now looks like this:

Guitar over Cat5 project 2

Tuesday 28 June 2011 at 2:26 pm

Moved into phase 2, here’s what I have now:


Basically a Cat5 socket connected to 4 bits of guitar cable with jacks on the end, and;

and a Cat 5 socket connected directly to 4 jack sockets.

Item 1 gets connected to the amp sockets: input, FX send, FX return and footswitch
Item 2 (stage end) connected by short patches to input/output of the pedal, guitar connected to the corresponding input socket.  For my test the amp I used had the wrong type of footswitch (momentary action rather than latching), so I had to plug the actual footswitch into the box.  All I’m really doing here is making an extension cable, but just using the medium of Cat5 rather than multicore!
BUT… the damn thing works!  No apparent crosstalk/interference/line hum/attenuation, even through a 5m patch cable.  I’d call that a success.  Next time, testing it in a proper band environment (rehearsal room)…

Guitar over Cat5 project 1

My stage guitar rig can be a bit of a bind when setting up and breaking down – it’s configured thus:

Guitar plugs straight into amp
Effects send to Boss GT8 pedal
Output from GT8 to effects return
Additional cable from GT8 to footswitch allowing GT8 to switch channel

So all in all 4 cables involved.  I wanted to try & cut down, initially by using a 4-pair multicore, then I could bring the guitar input down to the floor, keeping to a single cable run.

But multicore can be a bit expensive, and I’m an IT network technician with access to lots of Cat5 cable, so I started to wonder…  Could I run the whole thing over Cat5 UTPnetwork cable, put a RJ45 socket at either end then all I’d need is a patch cable of the correct length.

No-one as far as I can see on several Googlings has tried it, so the only way to find out is to experiment.

Today I have this:

which is an old guitar lead soldered to one pair of a bit of Cat5, punched down onto a socket module

and this

which is Cat5 cable punched down into a module with a jack plug on the end

Plug in the lead to my guitar, plug the 2nd bit into an amp*, connect with a 5m patch lead and… bingo!  It works!  No apparent loss of signal strength or quality.

*I did use a proper amp to test – the mini-Marshall is just to show schematic!

Next step is to put in the other channels and see if there’s any crosstalk, hum or interference with the FX loop running backwards & forwards.  Watch this space.

Acerbis Handguards on Yamaha TDM 850

Friday 28 January 2011 at 8:38 pm

As requested by my friends at Carpe-TDM here's some more pics of my handguards.

They're Acerbis Rally II's whose website is HERE. They were an easy fit, and have stayed put ever since I put them on, about 4 years ago. If you're leafing through the Acerbis catalogue, I also used the 'ATV fitting kit' which is no more than a stand-off for the inboard end. The bar end weights had to go, so the Acerbis expanding bolt fitment went straight on. Excuse the grubby state of the bike!

TDM 850 Aux Lamp Fitting

Friday 28 January 2011 at 8:31 pm

Here's some piccys & words following my installation of fog/spot/aux lamps on my MK2 TDM850.

I originally fitted some cheap LED units, but the bulbs started to fail, and of course they can't be replaced.  So I found these halogen ones on good old eBay.  Shipped direct from Bulgaria (yes!) and I think they look pretty sturdy.  Includes mounting brackets and relay/wiring.  Boffo.

I expected H3 bulbs in these, but it turns out they're sealed dichroic MR16 bulbs.  So easily replaceable, and there's even LED bulbs available (obsessed with LEDs? Me? A bit...)

Anyway, off to the garage, out with the allen keys and sidepanels, screen and inner fairing off.  As I'd previously run the old lights straight off the sidelight circuit with a dashboard switch, I used this wiring to run the relay.  I mounted the relay behind the sidelight (stubby screwdriver required here).

Next is to run the power direct from the battery.  I connected a ring crimp connector straight on to the battery terminal next to the main fusebox via an inline fuse, then ran the cable following the main harness under the airbox. (Wiring got tidied up later & fuse holder strapped in)

Then connect it all up; that concludes the live side of the installation.  The earths for the lamps were wired to the fairing stays on each side.  Pic shows earth point and the route of the main feed wire (green - it was all they had in 17amp).  I mainly used insulated crimps for joins where I might need to disconnect in the future, but some I soldered & insulated with heatshrink. 

Mounting the lamps was a single hole drilled in the lower fairing, and the brackets bolted through.  Bracket pic:

Lamp mounted; sidepanels still off:

Finished article - the camera decided they were too bright & adjusted the aperture, so not a direct comparison, but you can tell how bright these are:

The only drawback is that there's no 'focusing' of the beam.  It's a wide pattern so even angled down they're dazzling.  Having looked around a bit there are several bulbs available with a narrower focus for a bit more control.  Should make night rides a bit safer though.

And previous readers of the Carpe thread may recall the amazing wording on the pack of the original lights.  These ones are no exception:

And finally - these are my trusty £2 QD kneepads which are invaluable for crawling around under cars & bikes:

And my other very useful home-made invention - the Daniel Park-O-Matic keeps your bike upright in the garage, giving more space without hauling the paddock stand out.  It's a bit of 2x4 with a slot drilled in it.  I'm thinking of taking it to Dragon's Den, what'd you reckon?
