3D design for 3D printing day

On the 17th of June from 12pm to 5pm we are organising a day of demos and talks on the subject of ‘3D design for 3D printing’. There will be several talks and demonstrations on the subject of how to use 3D design software to produce physical objects for manufacture, whether on a 3D printer, laser cutter, or CNC milling machine. If you are curious about 3D printing and other computer based manufacture techniques but don’t know where to start, or if you have experience but would like to share skills and ideas with others, this could be the event for you. All ages welcome but under 16s must be accompanied by an adult.

The talks / demos will be:

Tom Bloor – Introduction to Fusion360.
Ian Norton – Modelling in OpenSCAD.
Andrew Baxter – 3 ways to model a real object in FreeCAD.
— break —
Dave Leack – 3D Printing with Blender: Common errors and how to fix them.
Ian Jackson – Modelling in Vectric Aspire.

The talks will last between 30 to 40 minutes, with a 20 minute break in the middle.

If you would like to help publicise this event, please download and print out this poster, and put it up wherever you think people might be interested.

Presence sensors again!

In my previous two posts I’ve talked about hacking cheap presence sensors to work on 24v DC rather than mains.

As does happen with these things, we’ve ended up with another different style of sensor from the same supplier!

pir3-pcb

The design of this one is actually more complicated than we’ve seen previously making use of zenner diodes to drop the +24v DC to 5v for the front panel PCB.

pir3-2

Thanks once again to Malc who eventually gave up trying to make this design work and posted me three up to look at, I shall enjoy the beer on you mate ūüėČ

Hack on!

Presence sensors revisited

In my previous post I talked about 24v presence sensors for Loxone home automation:

Is there anybody there? Click once for yes!

Shout out to Malc Crook (https://hackaday.io/mal8837) and Adam (https://hackaday.io/Bobbsta10) who both contacted me to say that the PIR linked to in the original post is no longer the one you get when you order the same item from the same seller ūüôĀ

Fear not, for I have hacked the new one this evening and it’s pretty straight forward ūüôā

2016-09-10-17-49-04

Well that mostly looks similar…

2016-09-10-17-49-45

Still looks similar…

2016-09-10-17-51-32

Well that’s different. The two boards are fixed together and the front board has to come away from the plastic shafts for altering the time and lux level

2016-09-10-17-53-30

Those are really annoying to get back in but I’ll come back to that.

2016-09-10-17-54-47

Different AC supply board this time around. Let’s take a look see what’s going on..

pir-ac-board-layout

So capacative dropper is driving an actual bridge rectifier this time rather than four discrete diodes. Seems like there’s a lot here we don’t need….

2016-09-10-18-24-24

I always end up with spare bits when I take things apart….

2016-09-10-18-48-00

Right, so now we look like:

2016-09-10-18-33-06

So having removed all but the diodes for protection and the capacitor for smoothing the supply, we’re left with +24v going in and a working automation PIR! I put the front board in place without screwing it in and put the spacers on the back board as it came but without the screws. We’re no longer dealing with mains voltage and the spacers keep everything sensibly… well… spaced… Best update the labelling…

2016-09-10-18-47-18

That’s a bit neater than the previous scribblings with a sharpie… ūüôā

I’m hoping that step by step pictures and the diagram will make it clear how this change works. The PIR module is 24v all along, all we did was remove the AC components and drive it directly.

There doesn’t seem to be an LED on this model. The relay is triggered by dropping the signal line from the front board to 0v. It floats at +24 otherwise so technically we could lose the relay completely and drive that back to an input. I’ve not tested that so your mileage may vary.

Hopefully that update will be useful to people!

Keep hacking, Ian.

Why make when you can bake

The upcoming open Saturday (Saturday 17th September) will see a change to the hackspace. ¬†While we busy ourselves with preparation for the Lancaster Fun Palace (October 1st and 2nd), there will be something spongy, crispy, something with a lovely crumb or maybe a good snap. Yes that’s right we will be holding an informal bake off.chocolate-cake-1576494_640

If you watch the BBC, you’ll be no stranger to The¬†Great British Bake Off which started back on the telly last week. Quite a few of us seem to be keen bakers, so for a bit of fun we’ll be taking our best bakes into the space for a bit of a competition.

There will be three prize wining classes

  1.  Biscuits or Cookies
  2. Bread
  3. Cake

Please feel free to bring your best bakes and join in

Prizes will be given for the best in each class chosen by those there.

(Please note we will NOT be baking in the space)

Okay so that’s the fun part.

We do need peoples help to prepare for the Fun Palace and there are, as always, jobs to be done around the space.

LAMM Membership

Hey All,

This is not going to be a short message, however I will get straight to the point: We need more members. Without any more members, then there is a strong possibility that we will not be here in the next few months. So, if you are already a paying member, well done! Continue being awesome. If you are not a paying member, or know someone who would like to become a member, then please join up here: LAMM Membership Request

We have two payment levels, which depend on your circumstances.

The first one is the Standard Membership Рthis is £25 a month, and will get you full access to the space, meaning you can come and go as you want to work on your own projects.

The second one is for the following:

  • Young Members ¬†– for those under 16, and will require a guardian present.
  • Student Members – those who are still in full time Education, at University, College, or another education establishment.
  • Supporting Members – for those who want to support the space.

This payment level is £10 a month, and in the case of the Young or Student member, will get you full access to the space as you would in the Standard Membership. The Supporting Member is meant for people who are not close enough to Lancaster to make use of the space, but would like to support us to allow us to keep doing awesome things.

More ballz

As part of the continuing Manchester MakeFest preparations, and in particular the Amazeballs challenge from Manchester HACMan tonight I completed the next step of my marble (well pinball) run drop.

This is a large version of the version 2 Lammballz. So essentially a Version 3 Lammballs and is 555mm by 300mm made from a combination of perspex and birch.

Big thanks to the ever-wonderful Tom Bloor for help with the setting on the laser cutter, design done as always in Inkscape. Images of the unfinished (needs lots of glue/fixings) version with business card for scale, below.

I Made a Thing

So last night I made a thing at the hackspace and although it is relatively simple and small I am inordinately proud of the thing that I made.

You may, or may not, have heard that there is a Makers event in Manchester (Manchester MakeFest, I believe this to be a faire or carnival of makers) that is to be held at the Museum of Science and Industry (MOSI) on the 11-12th August. For that event the folks at Manchester HackSpace have created a AmazeBalls challenge and we at LAMM are trying to create something for it.

My small part in this is to create a small pair of ball drops. One of which I am cutting out of wood using the laser cutter and the other I am making from scratch (predominately) using a 3D printer. This challenge is a great way for me to start to play with both Laser and 3D printing.

Last night I designed a simple rail in Inkscape.

I then took the simple rail and extruded it in OpenSCAD with a lot of patient and generous help from Tom Bloor (who guided this old duffer through the openSCAD way of doing things).

screen-shot-2015-06-11-at-14-26-00

And then I sliced the resulting stl files in the 3D printer softare.

Then I printed and played with them as they seem to work ūüėČ

It was a great achievement, I said it was small, for me and it was another example of how a place like the Lancaster Space can inspire you to create using a variety of tools even if you are new to them or an ‘old duffer’ like me. Thanks all for the pointers and help, a big thanks to Tom for all his gentle tutelage.

Stamp It

There was a small, determined, and succesful combined effort at the Lancaster Space this week.

Stamps

Those of you familiar with the MakerSpaces will know that there is a MakerSpace Passport. This is a copy of a traditional passport with the idea that you fill it with stamps from the various hackspaces you visit.

Hackspaces themselves are encouraged to make stamps for the visitors.

We at LAMM took this into hand and made a collective effort amongst some of the members to make a stamp for the Space and for the LAMM people.

Make It

  • Darren provided us with some laser-ready rubber from which to create the stamps.
  • Claire checked online for the details and did the organising of data and information.
  • Mark designed the logo in Inkscape.
  • Tom designed the handle and performed the Laser and 3D printer duties.
  • Ian drank coffee and cola and made jokes when we forgot to reverse the first cut.

The end result is something we are proud of and also means we have now costed the time, effort, process for creating custom stamps, which is another service we can provide or that we can teach to local people.
