The McKenzie’s Blog…

We started out a weeks camping by leaving the house about noon on Sunday. The drive to the camp site, Brickyard Farm Camp site (Banham, Norfolk, NR16 2HQ), was only about an hour or so from home. Even at the reduced speed we had to travel at because of towing the trailer. After a stop at Sainsbury in Thetford for a few last minute supplies and lunch as well, we arrived at the camp site at about 1400hrs, plenty of daylight left so we could take our time getting everything set up.

Lisa and Emma immediately found the horses in the fields to go and see plus a swing set to play on as well. I was a bit worried for a while, there were no other kids around. Then, a family came trooping back into camp. They’d been out to the Banham Zoo. It’s about 1/2 mile down the road. Anyhow, Lisa and Emma quickly became acquainted with Hanna, 7yrs old. They spent the next 3 or so hours playing all sorts of games and running around the farm.

The camp site itself is a small family run business. It’s run the brother of our neighbour, very nice folks. They popped around to check on us and see how we were settling in. Quite layed back, they haven’t asked for money as yet. The site is, as I mentioned, small. Only about 6 or so pitches, most with electric. We didn’t bother with that, I’d brought the 120amp battery with us. More then enough power for the week to run a laptop if needed and charge the phones. I brought a 12v florescent lamp as well but likely won’t need it.

The kids are knackered. They’ve had a busy afternoon that’s for sure. Tomorrow we’ll be walking to the zoo and checking out the animals and whatever else they have there.

Well that’s about it from here tonight I think. the big people are knackered too and ready for bed now as well.

Watch this space for the day 2 report. I won’t be posting pics on the blog, but check on facebook, flickr and mobypictures and of course Twitter.com/m1xzg for updates.

Btw, this is all from my phone, there are likely spelling errors, I will fix them later. Don’t think I have a spell check on here.

So, while looking for a small and light weight stove for hiking / SOTA whatever I decided to pick up a Hexamine pocket stove and give it a try.  I usually have a Camping Gaz type stove but it’s big, bulky and you need to carry compressed gas cartridges with it.  These themselves are big, bulky and can’t really just be chucked in a bin when they are finished as they are still a risk of exploding.

I’d really like a MSR Whisperlite but they aren’t cheap, however, they are very versatile.. best you read about them on the manufactures website (click the link back there).  At some point I’ll likely get one of these, but not right now. 

For now I’ll have a go with this Hexamine stove.    This the very same one I have picked up for £4.00

To night I decided to do some timing experiments to see how long it takes to boil water in both my crusader cup and a small aluminium kettle.  The Crusader cup took 6m20sec to bring 1L of water to a boil and the Hexamine cube held the boil for 3 minutes.  Might want it to boil longer if you were sterilizing water, but just pop another cube of Hexamine and it would be good for another 9 mins of burn time.  The kettle, which has a lid, only took 4m30sec and the same 9 min burn time on the cube so that means 4m30sec of the water being held at a boil.

A couple of pics and a couple of videos can be seen below.. click to enlarge or see the videos.

Well, now just have to try it out in anger one day in the field

Today after I finished work, I decided I needed to get out for a walk.  Emma was sleeping and Yuki was hoping to get some sleep before she started work in the evening.  Lisa didn’t at all want to have a sleep.

So, I decided to take her with me.  The question was where too.  I decided to take her to Wicken Fen again.  We’d gone there before (Wicken Fen…) with Lisa’s school.  That visit was good for the kids but we didn’t really get to see too much of the place.  Today when we went back we’d ended up walking about 1.25 to 1.5 miles around part of the area.  Lisa had a good time but sure was tired.  Surprisingly she didn’t fall asleep on the way back home.

There are some pics and a video from the day HERE – here are some samples.

Yesterday I took a walk around part of Grafham Water, however my GPS logging of the walk didn’t really pan out.  Some have considered to be a pretty great and impressive person, but even I can’t walk on water, I don’t consider that a failing though because I like to swim, and well it tough to do when you can’t get past the surface

Anyhow, I took a load of pics which you can see if you CLICK HERE.  Some samples of the pics.

Today I took the girls to Welcome to Wild Britain – Bedfordshire’s Butterfly and Conservation Park.

Yuki was working and I needed to get out of the house today with the girls, so I decided to take the to this park.  We’d talked about it for a while but today was the day.

You can see the photos from the Flickr Gallery.

The girls had a great time.. they even did some crafts there too.. they painted some paper butterflies, they did some drawing and coloured in a small bit of paper that was then pressed into a badge with a pin in the back to put on their clothes.

I’ve been searching the net for ages looking for the wiring diagram of the 12VDC power cable for my Respironics REMstar Plus CPAP machine.

Not having any luck at all on the net finding the information I needed to build a cable, I’ve finally broken down and paid £26.00 (including shipping) to buy one.  I’ve wanted a DC cable mostly so that I could a) go camping without the need to have a tent pitch that was powered (extra cost), and b) be able to power my CPAP should we have a prolonged power outage at home (fairly low risk of this, but a risk none the less).

Click on the image below to see the full sized one.  This is a page from the manual that came with my cable.

Basically, should someone have posted something like:

To make your own Respironics Shielded DC Cord, Part number 1001956, you will need the following:

• 1 x 2.1mm (5.5mm outside) X 15mm Coaxial DC plug
  Such as: Maplin’s Part number HH61R (www.maplin.co.uk)
• 2-3m of suitable wire for a max of 7amp DC (depending on your CPAP model)
• 2-4 Clip on Ferrite suppressors, such as Maplin’s part N89AB
• 1 x 12VDC cigarette plug, suitable for upto 7amp DC

The construction of a DIY Respironics CPAP DC Cable, model number 1001956 is quite simple.  Wire up the cigarette plug to the DC plug that will go to the CPAP, be sure to wire the tip of the cigarette plug (Positive 12V, I suggest a multi-meter to confirm this in your car or battery pack you intend to use) to the centre connector of the 2.1mm DC plug.  Wire the negative to the other remaining connections. 

At both ends of the cable, as close as possible to each of the plugs, leave not much more then 3-4cm of cable “exposed” put a couple of the clip on ferrite RF suppressors.  These are quite important as they will ensure the dc is free of RF (Radio Frequency) or Electromagnetic noise.  These, should they get into the machine, could cause damage.  You can likely get away without them, but frankly for the extra £5 it will cost for these it’s worth saving your £500+ CPAP.

That’s all there is to it.  I really hope people find this useful, for some reason there has been a black hole of info about these cables, and I’m not sure why.

**DISCLAIMER** This information has been provided purely for theoretical and personal information.  I will not, nor can not, be held responsible if you are not competent enough to build this simple cable and end up damaging or destroying your CPAP.  I’m pretty sure in the wonderful lawsuit happy world we  live in it’s also most likely a violation of your warranty to attach a home made DC cable to your CPAP machine.  You have been warned, don’t come crying to me if you blow something up, also, don’t ask me to make one for you.  These are beyond simple to make.

On June 26 Lisa’s pre-school, Ladybird Pre-School, had a day out at Wicken Fen.  This is a National Trust owned Nature Reserve near Cambridge.

The weather couldn’t have been better for the day.. it was a little overcast, but that kept the heat down which was good.
