G25 game wheel repair...

I have a Logitech G25 force feedback steering wheel. (i.e. a very expensive computer games peripheral!)

It is malfunctioning and according to the Internet the most common reason for this is that a small plastic disk associated with the optical encoder is broken.

If I were to open it up and find that this disk is indeed the problem, could I mail you the broken disk and you replicate it and send me one with a few spares back?

It's a common enough issue that if this works I suspect you could make a fair few bucks selling replacement disks on eBay.

Hi Travis,

This is the real strength of 3D printing - creating those hard to find, or impossible to get otherwise, parts. Sounds like a simple job and no issues with mailing me the defective part. I'll send you a PM and we can go from there

Hi all,

I have started a thread here about ideas for printing laser pointer holders. If anyone is interested or has design ideas, please send me a PM or reply on the thread Thank you!

Secondary design

Hey all,

Big thanks to Meru for getting this design to print. This design has 2 large threads that work perfectly.

It had to be incredibly precise as the thread holds the secondary mirror in place. And it works.

It also has a plenum to create a air flow effect over the secondary.

It is the secondary of a 16 inch RC I am building.

That looks excellent Brett, what's it weigh? I've been thinking of replacing the one on the RC12. How's the focuser working out?

dual dovetail stalk

Hi all

I have a home made lightweight dob and had explored using a couple of finders. I had found a few aluminium/steel dual finder stalks, however I need to keep the weight down. So, Meru recently printed one for me using this design: https://www.thingiverse.com/thing:608132/#files

I'm very pleased with the result, which is more robust than I anticipated. And Meru was a pleasure to deal with.

Cheers

Andrew

Just received my order from Meru of a couple of Bahtinov masks including one for a FSLR lens hood that I use as my guide scope plus a lens cap to suit so I can leave the hood on.
And the most important parts being cover plates to replace the ones I destroyed so I could adjust the EQ6 mount. The new ones are made of a baseplate glued to the mount and a cover plate screwed to that so it can be easily removed for future adjustments.
Another happy customer. Thanks Meru.

Brett,
Been great working you, can't wait to see our other projects come to life!

Andrew & Ken,
Thanks for the feedback it was fun helping get these custom parts made

All,
As always lots and lots of bits and bobs to be designed and/or printed. I will stop listing every job from now on and only occasionally place an update when something really interesting comes up. In particular have been these three parts:
  • Brett's custom secondary. Been a great project to create a large, 3-piece design which screws together and also has angled vents to create a vortex-flow over the secondary for efficient thermal transfer and dew prevention. The threads to screw these pieces together had to be custom designed and on the whole took several iterations to get it perfect.
  • ParamountME steel pier. Member had access to a laser cutting company and created multiple files for the machine to cut out every part of the pier out of structural steel (base, top and bottom gussets, upper plate with mounting clearance holes etc).
  • Custom tube rings for a 16" RCOS. This has definitely been an interesting bit of work I got asked to do. Had to design two sets to tube rings, using a laser cutter, using stainless steel and perspex as the sandwich material. The rings clamp to the RCOS via the felt-lined perspex (shown in red in the 3D CAD renders). There were alot of constraints, such as mounting hole size and location, perspex shape to maximise contact with the stainless rings, aesthetics and function of the truss cutouts to save weight on the stainless, and how to best integrate the aluminium blocks (not shown) which will mount the tube rings to the mount as well as serve as the clamping mechanism to secure the scope. The joint also had to be designed to meet a certain bolt type and hinge design per request of the member. Lastly, I provided a sketch for the operators to verify various dimensions to ensure the final parts are cut correctly. This item was finalised today and is now ready to be cut, can't wait to see the outcome!
As always, clear skies

Hi Meru,

Got my mask today, looks very good and I like the label, too! I might paint it in a bit to define it.

Cheers,

Bart.

Hey all,

I thought I would show some of the 'out of ordinary' parts that Meru has drawn up for me.

Not only has he been doing 3d printed parts but also for laser cutting steel plate, in Aluminium, stainless and polycarbonate. The pictures in this post is the 3 piece assembly that we used to mount a 150mm secondary mirror to a van slyke manual secondary I had. This is for a redesigned RCOS 16 inch I am building.

There were also air vents so I can blow air directly onto the secondary surface, hopefully eliminating dew and surface boundary layer on the secondary mirror. The assembly parts all screw together via the 4 x 3d printed threads.

These are 3d printed parts to Meru designed to mount the Renishaw axis encoders to my mount. Cant wait for unguided imaging at over 3000mm focal length.

Anybody with Renishaw encoders on their mounts (i.e. Planewave Ascension owners) will know the satisfaction of the green light on the readheads!

Mounting rings

Next the mounting rings.

I already had dream dovetail plates. So I needed to make the mounting rings for the custom tube.

So we designed up a mounting ring system made from stainless plates with poycarbonte sandwiched in-between.

Meru made up the CAM files for the laser cutting of both the polycarbonate and stainless steel, including bolt holes.
