2012

So its a new year, and to go with it is a new plan. This plan includes pushing some things forward, dumping others, and keeping others exactly the same.

Step 1 of the plan, thanking everyone for last year. By all accounts, last year was terrible. So many issues, so little corrected after them. Wouldn’t have got through it however without the help of a few close friends. So with that, thanks guys.

Step 2, kick start some smaller plans. Those things you were planning to do? Less thinking about it, more doing it.

So what are your plans?


Review: Fluke 233

Late post is late.

 

Many thanks to e-14 for this one. Some time in summer, I won a lovely bit of kit. At the time I was cursing, the day I found out I was only round the corner from the offices but couldn’t make it to drool in person. However, following a short wait (and a looong drive home from Leeds), I got home to find a box. What was inside it you ask? Simple, a Fluke 233 and some e-14 goodies.

 

The Fluke 233 is a remote display Digital Multi Meter with an impressive feature list including:

  • Measure up to 1000 V ac and dc
  • Measure up to 10 A (20 A for 30 seconds)
  • 10,000 μF capacitance range
  • Frequency to 50 kHz

 

Whats impressive about this, aside from the features, is the display. For those who have parts of systems scattered about, or in awkward places, or just want to monitor something from the other side of the room (We’ve all been there right?), the display module detaches. This allows you to connect up the meter as usual, but walk away (Up to 10 meters) with the display. To make it easier the display itself is magnetic allowing you to easily attach it to a nearby surface such as a control box you are working on. The main unit however is not so lucky. With the basic kit your only option is to carefully place it somewhere stable. Or, take advantage of one of the accessory kits. One such item is the ToolPak. This simple strap clips onto the back of your Fluke meter and adds the magnetic feature seen in the disaply module. Should you not have a magnetic surface available, you can always clip it onto another appropriate surface. Should you want to refrain from hanging about, there is the stand option, seen on many meters. Simply flip it out from the back of the meter to prop it up while you work.

Aside from the amazing remote display, the meter itself is pretty standard. Auto ranging, Min/Max/Avg options, temperature and frequency features, back light, true-rms etc. A good quality meter, great for any engineer working in potentially hazardous or awkward spaces.

 

While working with it, I haven’t had any major problems (The minor ones all being down to a lack of tea), the battery life is ok. It might struggle with heavy use, however it does not need anything special, just AA alkaline cells. The wireless function for the display turns off when connected to the main unit (and resorts to an IR connection, no dirty pins to deal with) in order to conserve power. Over all it is a very nice unit, well worth the money, if a little on the expensive side. Not one for beginners thats for sure!

 

My only complaints with it are with the kit contents. While it is not expected that the meter comes with a case, I do feel it could have came with one, or at least some nice bubblewrap to package it. For those considering getting one, or who have one I do recommend getting a case. You can get one from Fluke directly or locate one for yourself. Just don’t forget it must have room for all your accessories! My other complaint is with the manual. It is on CD. While not a problem for most users, some platforms may have issues opening the included files. Should you need the manual, you can soon download a copy from the Fluke website.

 

My rating? 9.9/10

Marks are lost for the manual not being as accessible as it could be.

 

Worth buying? Yes, if you are going to need the remote display, go for it, if not, stick with one of the other models and save the money from the batteries.

Steve Jobs

Earlier today it was announced that Steve Jobs, one of the men behind Apple, has passed away (http://www.bbc.co.uk/news/world-us-canada-15193922).

This is a sad day for everyone. Whether you  like Apple products or not, it is hard to deny that his work has made a great difference in the world. Without him, we may not have had things like the Macbook, the iPod, the iPhone. Certain printer drivers may not have been as good as they are.

For me, Jobs played a part in where I am today. Had it not have been for the inspiration from him (and that of many others), I may not have been in computing now. It is safe to say I owe a lot to Jobs and the work he has done. Lets not forget of course his work in other areas that have touched many more of us.

Pixar was co founded by Mr Jobs. Since then they have produced nothing but amazing films. At some point, we have been touched by the work of Pixar, or know some who has been. Had Jobs not been involved in Pixar, who knows what would have happen. Perhaps no Wall-E? No UP?

No matter what he has done, he has touched countless people in some way. One of the best comments I’ve read so far about this tragic event is from Mr (Evil) Wil Wheaton http://wilwheaton.typepad.com/wwdnbackup/2011/10/your-time-is-limited-so-dont-waste-it-living-someone-elses-life.html

A sad day for everyone. Steve jobs shall be missed. Rest In Peace dude.


Working with Foam: Tools

So you want to work with XPS foam (Typically known as blue foam, pink foam)? First of all you’ll need your tools. This is by no means a definitive list. This is based on what I use and the most common suggestions I’ve seen. If there is something you think is missing, comment!

First up, and most importantly of all, safety!

  • Face mask
    When working with XPS, a lot of dust is generated. Some processes create more than other, for example sanding. This foam, is NOT good for you. Always use a face mask, FFP2 or above should do. Failing that, a respirator.
  • Safety Glasses
    As already established, dust is bad for your lungs, so naturally, it isn’t too good for your eyes too! Any reasonable safety glasses should do, just make sure they are a good fit!
  • Gloves (Optional)
    Our favourite dust can be a bit irritating. If you get sick of brushing it off your hands, or simply don’t like getting your hands covered in PVA, paint, adhesive, get some gloves.
  • Cover alls (Optional)
    As with making anything, it can get messy. I would suggest using some cover alls, or at least some old clothing. No need to spoil your good stuff when you can cover something else in muck! Personally, I prefer cover alls, fewer gaps when the dust starts flying!

Now you have your safety gear ready, its time to start getting your tools.

  • Marker
    Pretty self explanatory. I’ve found a simple black marker is the best thing to mark up your foam. Reasonable felt tip will mark your foam without damaging it (Beyond marking it anyway)

  • Snap-off Blade Utility Knife (Multiple)
    The blade needs to be long enough to go through a single sheet of foam. This is by no means the best method for cutting large pieces from the original sheet, but it works.
  • Bread knife
    Optional, but for larger bit, a thin bladed bread knife can be a great replacement for trying to cut through sheets with a utility knife.
  • Hot Wire Cutter
    Personally, I don’t use one. If you have one, use it, you will get much cleaner cuts that you will from a blade.
  • Brush
    When it comes to it, blowing the scraps out the way is a good plan, however if you have a mask on, its not that easy (Unless you have a compressor handy of course). The solution to this is to have a brush handy. Not only can you move the foam out the way, but when you generate dust from fillers, it can be a great help!  Can’t forget of course, when you go to seal or paint your creation, a brush is always helpful.
  • Sand Paper
    A fine sand paper will do for foam. Too rough and it will just tear the foam. Foam is best sanded when it has been sealed.
  • PVA Glue
    When watered down a little bit, this can be used to seal the foam before sanding and painting.
  • Solvent Free Grab Adhesive
    Unless you are amazing, you will have create things in different parts. A solvent free grab adhesive works wonders for glueing the parts together, laminating sheets and making repairs where you have shaved off a little bit more.
  • Filler
    A general purpose filler is highly useful for filling in gaps and smoothing surfaces where sanding is just not the best option. A scrap bit of foam or some proper filling tools are needed if/when it comes to this.
  • Masking Tape
    Multitude of uses from holding a template down to holding pieces together while the grab adhesive sets.
  • CAD Software
    One thing to sketch up your item on paper, but once in a while you may want accuracy, share your designs or simply print out copies as a template you can destroy. Some basic CAD software can be a great help with that. Should you have access to the equipment, you can also run your foam through a CNC machine.

Something missing? Leave a comment! Stay tuned, there might be some more of these later.


Music Videos.

One of my favourite songs. Can’t help but love the video too.

TV On The Radio – Staring at the Sun

Although that does raise a question, what is your favourite song?


Site Maintenance!

New round of site maintenance coming up. Should only cause issues on partner sites and not the main one. If there is any weirdness tomorrow, please let me know!


Mini Project

New mini project up today. Following a request on Twitter from a researcher looking for a search application, I was curious and started writing my own. A few hours research (Mostly rebuilding git after a machine rebuild) and a basic design and program is ready to go. Although it has a few issues and some missing features, the tool takes a query from the command line and returns the 15 newest results. These are then outputted to a CSV file for later use. To take care of the heavy lifting, the Twitter4j library is used.

Want to try it or contribute it? Have a look at the repository.


Hidden Science Map

Think scientists are just stuck in labs all day and follow all the stereotypes? Well you are wrong! Slightly. No promises about some of the stereotypes…

To prove this, the Science Council launched the Hidden Science Map project. The map, aimed at school children is designed to show that scientists, engineers and technologists are everywhere. They play the same sports as you, shop in the same places you do and have ‘normal’ lives.

If you are a scientist, engineer or technologist, I urge you to sign up and get yourself on the map to help promote STEM careers!
