Yeah I thought it would be a bit easier to find the stuff. I spent a lot of time looking at Arduino and it looks perfect. Although the router weights 9kg its just turning a threaded rod with a fairly shallow pitch. It doesn't take much really to turn it but its hard to guess what that is in NM.

Hi bernard,

Yeah I was in at the beginning of something great I think with the DIY cintiq!

I'm ok soldering, and happy to pay to have a PCB board made up. Regarding the programming side, I'm actually a computer science student nowdays so thats the bit I'm ok with.

It would be great if you could help me work out what sort of kit I need and a design. The most confusing aspect at the moment is what power motor will be required. Its only going to be turning a threaded rod so there shouldn't be massed of resistance.

Hi Guys,

I'm looking to make a foray back into the electronics for a project. I have a new router in my router table and would like to incorporate a rise and fall mechanism in it that is controlled by a stepper motor. The mechanics are already in place a threaded rod and static bolt on the body of the router provide the movement up and down when the rod is turned. It doesn't require a huge amount of torques as the router only weights 9kg and the springs are to be removed.

What I'm after is a programmable chip board, pref C lang and support for a range of input buttons which will be at minimum 4. The 4 buttons will control the rise and fall. One button will raise the router fully, and the other lower it fully. The other 2 will raise and lower in 1mm increments.

Do you suppose any of you guys could give me some help in getting a circuit diagram going and what sort of hardware combinations I'd be looking at. I have the programming side down but other than my bongofish cintiq experience my electronics are rather limited.

Thanks in advance I hope you guys can help!

Nice to see the forum is still going strong. Lots of completed builds online now. Its nice to be able to say I was there in the beginning!

Hello to all the old hands!

Well it will still be cheaper than the £400 I paid to personalize my car. Im the proud owner of CH** EMS number plate. Smiley

Id bet money that cross piece is part of the bumper.

A much quicker and cheaper way to remove that front logo is to take it to a body shop where they can saw away that part, rebuild it with filler and paint it. Wont cost much at all.

Wowzers!

Thats what I hoped for my build to be like, I should never have cut the hole out on my build Sad

Super Work!

Cant believe how good this thing looks, fantastic job!

Yeah I just did my sisters. Popped it open and bought a new power pin off ebay even thou it probably just could have had the current one re soldered and its as good as new.

Thats not a bad tip actually, you could take a Volito or similar small tablet, be up front about what your testing for and test it. That been said 99% of people from here got their screens from ebay.


As for a real test, basically the problem with interference is that something is playing up with the magnetic field, so something like a itchosketch board but really sensitive may show up the interference. In Theory, trial and error I think is the best way.

It only broke because I was a bit heavy handed with the cover, an it would have only taken 20quid for a new screen and Id have been back on the road. In my eyes the goal had been accomplished and onto the next project!
14  General Category / Can't stop building / Laser Wood Cutting Guide on: April 23, 2008, 10:22:01 PM
Im ready for my next Electrical DIY Project. Having been doing a lot of woodwork lately I really fancy making my own Laser Designator that the fancy power tools have to show where your cut is, or indeed where its going to be when your wood is covering the blade or bit of the router.

I'll show you my little shop first and the router table I said I was making back in the Photo frame thread (Ive got some pics of that to upload as well)

Here is the router table made out of the old tiny desk top.



Mounted underneath with dust extraction in the form of an old vacuum.


Close up of the top, I need to make a new fence this one is just temp:



My cheap table saw.

The main work bench, I built this just after I did my DIY cinitq which had to be made on the floor as I had no work space.



My current work in progress:





So what I want to do, basically I want a system that I can move between the table saw and the router, for the router I want a cross hair of laser line that I can mount off to the side and line up with the bit before I start cutting. For the saw just a single line. Where do I start Bongo?

I deal for you Colin, you could use the base of your Intous case as a mold to make more for others.
