Hi there

Got my copy a couple of weeks ago. It seems to be the 'corrected' version. I'm just waiting on some parts to make up the LED strobe. A good read and liking it so far!

So many projects so little time!!

I'm hoping mine will be with me on Monday! Looks interesting and fun.
It's a present from my wife!  smiley-lol

Looks good to me. Though your sum has 3V in it but the result is correct for a Vf of 2V. It's also good practice to always round up to the nearest standard value even if your within a couple of ohms of a lower value. It looks like you need 16 resistors for the column pins only. 8 for red 8 for the green.

On Saturday I scored 6 metres of UPVC fascia panel for nothing. This is for a Dr who Prop See image -



This may become relevant if I manage to get my head around programming my Arduino to make the prop 'function'.

This will consist of counting from 8 - 0 rounds, detecting that the magazine then has been changed to begin again. Also each shot requires the gun to be 'cocked' using the pump action. Sound and muzzle flash will also be a part of the effect.

In theory Arduino will make this simple, in terms of component count and simplicity and allow for a realistic operation of the 'BFG'.

I have a circuit drawn up that uses 3 555 chips and 2 chips to drive a 7 segment display which will work fine. At this time this circuit has the upper hand......On the Arduino I can make the LED blink, several LED's blink but so far Mr Lightbulb hasn't gone 'DING'

Hi there

It's an impressive piece of kit  smiley-grin I reckon you'll get some very positive responses from the EM forum, I see you've joined, I'll be watching this with great interest.

7  Community / Bar Sport / Arduino- when is one never enough? on: January 28, 2011, 01:00:38 pm
Hi Chaps

Having merely scratched the surface in my few weeks as an arduino owner I have come to realise I am going to need more than the one arduino I have. This is in part due to the huge quantity of neat,cool,brilliant, amazing projects and codes available to all.

I will be making my own PCB's and using my clone to program the various units as I go.

How long did it take you to realise that one was never going to be enough?

Hi there

A very impressive piece of electronics and Arduino. You might consider showing this at the electromusic.com website. Specifically this link, to the DIY section -

http://electro-music.com/forum/forum-112.html

I am sure it will be well received by the members there, of which I am one. You will find many other DIYers who have also developed their own systems and designs, many using traditional analogue electronics, some of which are made available as kits or PCB only.  Good luck with it!

I like it. I had only just joined before the migration but this is a very nice upgrade. I would like to echo Biocow with reference to the pop ups. I like the idea but they do vanish very quickly. Can this be addressed?

Hi Chaps

The penny dropped just 5 minutes ago! I obviously misunderstood part of how to get here from the original site. It's only taken 3 days  smiley-lol

Very nice it looks to. So well done everyone involved and it's nice to have 'arrived' eventually.  smiley-red

If it has any bearing ULN chips can be stacked to increase the Amps they can handle.

Absolutely. If in doubt just use the clothes iron as is. It is a knack and practice will pay off.

Hi there.

Inside the laminator there are 2 sealed thermostats. These need removing. They are in series BTW.

The replacement thermostat is from an old clothes iron. It was fixed to the iron by a machine screw so was easy to remove.

I then used the same screw to fix the irons thermostat to the laminator. I gut a groove in the bolt up it's length for a 1/4" so it would cut and clear it's own thread in the aluminium channel. The bolt needed cutting slightly shorter so it would hod the thermostat securely.

There is also a thermal fuse strapped to the aluminium channel. Remove and join the wires together. The wires from the original thermostats connect to where the irons wires were on it's thermostat.

Do ensure that there is no possibility of making the laminator aluminium extrusions MAINS LIVE!

The plastic case needed a hole cut in it as the thermostat is quite tall. I built a shroud round it to prevent any issues with touching mains live parts. The dial is fixed with silicon sealant.

THIS IS MESSING WITH MAINS POWER PLEASE BE CAREFUL!

A thermometer would be handy as well as the scale on the irons dial isn't exactly accurate and it is easy to get the rollers smoking!

The largest PCB I have done with it was 5 x 4 inches. My unit is getting a little tired and the gears in the AC motor gearbox start slipping if the unit starts getting to warm. But it has done a lot of boards.

That's one of the online tutorials I read when I was 'investigating' the TT method. True to say it was the most influential for me  smiley Here's to GOOTEE!

My Laminator is a 'texet A4'. cost me £10 sterling. The modification was removing it's thermostats and replacing them with the thermostat from the iron I was struggling with. I really need to get a thermometer as well as there is a fine line between working and the rollers starting to smoke slightly =D
