Intro

Dome

I love Geodomes! There I’ve said it, you can argue till your are blue in the face that teepee’s are more practical, yurts are more traditional or a marquee is more user firendly… none of them are as cool as a geodome! Therefore I’m going to be making one! I just need to buy my van first as there is little point in making one without being able to transport it.

 

(Update 2014.03.11 – I’m now doing the van up. A geodome is getting closer!)

Covering Your Dome

This is going to be a UK based dome which means that waterproofing is a greater consideration than UV blocking heating from the sun! Having said that it would be helpful if it wasn’t a complete heat trap or I’ll end up frying all the lovely guests!

Review So Far!

Having had a quick look into this it looks as though its going to go on the back burner for now as my initial plan was to have a dome of around 2.5m radius, with various things supported by the frame itself (lighting, a swing seat and so on!). Plugging this into the dome calculator at http://www.byexample.com gives me a rough total strut length of around 172m for a 3v.

£10.50 (25mm Galv x 3.75m) = £481.60!

http://www.tlc-direct.co.uk/…..
£7.50 (20mm Galv x 3.75m) = £344!

http://www.megatradestore.com/Tube_Steel__Alloy/….
£538 (30 x 6m X 33.7MM X 3.25MM) = £538!

This is getting expensive as I haven’t even thought about a cover for it yet! Back to the drawing board.

How about PVC conduit instead of the galvanised steel? It would then be tougher to make the geodome as I’d now need to make star connectors instead of flattening and bending each end of the pipe.

20mm White PVC 3m = £1.15
172m = £65.93

20mm White PVC Heavy Gauge 3m = £1.85
172m = £106.07

http://www.jpldirect.co.uk/…

20mm White PVC heavy gauge 75m = £16.13 + 20%
225m = £58.07

This looks much more affordable and with the bundles of tubing I may be able to increase the size of the dome! It’s not what I was originally after though so I may have to have a think on it.

Finishing Touches

I have a few ideas for finishing touches but I’m only going to spend time on these as and when I’ve built the dome!

  • Astroturf flooring, slightly raised to allow water to run underneath.
  • LED Chandelier
  • Swing seat hanging from two apex
  • Narnia lap outside the front door

3.5mm Input to Car Stereo

Project Status: Abandoned

Intro

The idea behind this project is to add a 3.5mm audio jack socket to my car. I currently have a Toyota Avensis with all of the factory standard equipment, including a single CD – CD player / radio. At the moment I am listening to a very small collection of CD’s and on occasion an MP3 player using a mini FM transmitter. FM transmitters are rubbish in built up cities with little spare bandwidth.

Once out to a 3.5mm audio jack it would be nice to mount that on the dashboard on a spare switch point. I would do it on a spare switch point so that if it needs to be removed or updated only the switchpoint cover needs to be replced and not the facia or any other large (and expensive) part of the dash.

Review So Far!

Shouldn’t be too difficult to do and will set me back ~£50 but leave me with a 3.5mm audio jack socket and a haynes manual!
