Folding Grill

I’ve gotten bored of trying to balance bits of old disposable BBQ on rocks when camping so I decided to make a folding grill.

The parts list is pretty simple -

  • 2m of 25x25x3mm Angle Iron
  • 2m of 25x15x3mm Angle Iron
  • 5m of 3mm steel rod
  • 300x300mm steel plate
  • 4 x nuts and bolts

This is also a good excuse for me to buy some new tools like a welder!

I did try to scrounge the parts for this but the scrap men have done a pretty thorough job of taking anything not bolted down so I had to buy most of it new.

Step 1

Cut 45 degree  mitre’s in the Angle Iron

Step 2

Heat the bend points and slowly bend the metal.

Step 3

Weld the two corners of the Angle Iron together and weld the steel plate at one end. As you can tell by the picture this is the first time I have ever welded! I would have made the welder myself from microwave transformers but when you can buy them from eBay for £20 it’s not really worth it.

Step 4

Cut the rods to length and weld them on.

Step 5

Grind down all of the nastyness and spray on some high tempreture BBQ paint.

Step 6

Cut the legs to length and cut a notch in to one end so that they can hinge then drill the legs and frame and bolt it all together. I also added some cross bracing to the legs to stableize the whole thing.

And your all done!

UPDATE!

Here it is in action

Power over Ethernet Tester

Ever needed to see if a network point is live? Using POE? Then this might be able to help.

All it does is put the 48v from POE through a couple of power resitors to somthing  the LED’s can handle.  I’ve wired this up so it can deal with the proper POE standard and the Cisco standard.

Unfortunatlly it doesn’t seem to work with all Cisco routers but it passed some time making it!

Firework Launch Control

A friend of mine wanted to be able to set off some fireworks from a safe distance. After a little research it was decideced that off the shelf products were too expensive,  so I came up with this.

DSC00509.JPG At it’s heart all this does is create a short circuit accross a 10 ohm resistor. 12v will do a pretty good job of melting the resistor which would be simply taped to the firework fuse. As you can see in the following pictures it is simply powered by a 12volt cordless drill battery and even comes with it’s own carry case.
