Folks,

We'll probably have a decent lab table sometime next week. It is the modern type with the back panel area. The question is - where shall we place it ?

In the real world - it exhaust would exit high on the roof - with a large no-go area around it -- but that is obviously not possible - nor is the rest of the space suitable for that :) So next best, I guess, would be to have it vent on the backside - i.e. the smoking balcony - as opposed to the normal side.

Any thoughts ? Does it make sense to use this as an excuse to start a bio-hacking corner (where we'd also coat the floor a bit, etc) ?

Would this be suitable for putting in the dark room / wet lab room,
this has windows that could be modified for extraction.

Don't those windows also open onto the area where there is no balcony,
so nobody can stand outside ?

If it won't fit into the designated toilet, maybe it could go just
outside (where the small lathe is located) and vent through a duct
like the laser cutter.

Grin :) yes :) -- but that brings up a much larger issue. And really - if there is even the most remote risk of that (and at those volumes) - then we certainly should do a lot more health&safety, training, registering, drills and regulation. Our current space is not suitable for that at all.

Hi, any news on this? If you want me to get a streetvan to pick it up I need to book the van, so dates+times+how long you think it'll take would be good ;) 

Cheers,
Catie

So zee beast has arrived. It has turned out to be a lot fancier than expected - and in good condition. And has come with good lights as well. All tested and ready to be mounted.

So where to place it ?

- In the soldering area (as it is also a very nice soldering and electronics table) - down side is that we'd ideally want to contain the bio hacking to the other room.

- dirt room - roughly where the tools are. This is nice and near the water - and near the emergency exit - which is not bad. And easy to vent.

- remove the wall in the biohacking/darkroom (as we did on the other side) - and fit in that room. Would fit very nicely - and again - venting and water is easy.

Suggestions. Is this something we can pick up at tonights biohacking evening ?

Thanks,

Dw.

It looks amazing!

I'm keen on option 3 because it's a nice compromise between noise, dust, and keeping the biohackers contained somewhere. Also because it might mean sledge-hammering something.

Which wall are you referring to, because as far as I am aware no wall
in the hackspace has ever been removed aside from the gap between unit
23 and 24?

If you mean the one between the sink and toilet, removing this is part
of the overall plan - so if there are no objections I think it is safe
to go ahead with it.

That is indeed the very one I was thinking off.

This is now in progress. We took out the toilet seat and sink (they're on the balcony, unharmed), just removed the glass, and will next take down the wall.

Adding a few more details:

* the toilet cistern has also been taken out and is on the balcony (forgot to mention that earlier)
* there will be enough space on the outward facing wall for both the new workbench and the environmental chamber
* we will be able to store the toilet under the new workbench
* we may be able to reposition the sink with a bit of extra pipe, if we wanted to
* this leaves both corners of the inward-facing wall free for darkroom equipment.

Let me know if I can add any more details.

More updates and photos coming up later by Dirk and Catherine.

The workbench is set up, at the moment a few inches away from the outward facing wall because that still has pipes attached. And the extraction fan needs an exhaust pipe, in the meantime it's more a circulation fan as spooq pointed out.

Let's figure out who can help make this happen.

It's pretty. And big. Will make a good lab space.

Quick Braindump before I blow my buffer.

MOST IMPORTANT:

- Thanks to all involved. That was a most amazing bit of teamwork. Remove a wall; remove a window, toilet, cistern, doorframe, window, clean the room

- And then mount a complex piece of machinery inside it - larger than the door. And heavy.

- And all that in just a few hours.

Most impressed. Thanks !

URGENT:

- We may have made a design mistake with the inverted cup to seal off the toilet outlet; it may be able to get sucked into the duct.

=> todo: check that that is not the case; or if the case fix/tape-etc.

- We forgot to put the reservoir inside. It is still on the balcony.

=> todo: rescue.

Somewhat urgent - blocking use.

- Right now the desk is not screwed to the bottom frame. I think this needs to be done. No idea how. Suspect needs drilling some holes.

- The left glass panel (with bolts taped to it) has not been secured.

- Buy a proper plastic cap for the small sewer duct in the corner; and a bigger one for the toilet one. They sort of look like this
http://www.drainageonline.co.uk/Land-Drainage/Land-Drain-End-Cap.htm or get the fancier screw cap one and some glue.

- If we're postponing the wash basis - the taps should probably be removed and replaced by these:

Longer term:

- When we leave the space - toilet and basis need to go back. Basin we likely will mount - but toilet is a bit of a pain.

=> do we keep it - or do we donate the ?? 50 ?? UKP (guessing!) needed to buy a new one - and put it in the hack space piggy bank. Or do we put it in the other toilet for now ?

- We should be able to move the thing much closer to the wall. Problem is that the plumbing is in the way. Various options.

- slide it towards the wall and shorten the frame.

- remove the bottom frame - and mount a simple horizontal beam on the wall with a few anchors to take the bulk of the weight; and then two simple plates Left and Right with generous holes for the plumming. If you'd put a shelf between them you'd have plenty of stiffness. We have plenty of double plywood plates to do so. Alternatively - this arrangement could be across the full width.

- muck around with the metal frame - but cutting large holes may not be fun. So that it fits around the plumming.

- Outlet to the outside. Should not be too hard

- a bit of plywood or similar to ceiling and sides - and leaving the window(s) simply open behind it all.

- heroic cutting of a large hole in the metal top - and running a flexi-duct out.

- The room has no power :)

Other thoughts:

- If you open the panel on the top of the lights - you'll find a lot of fancy electronics, fuses and what not. These let you add additional lights, UV, etc with ease - it is all prewired; so any light can just be wired up with simple 2 wires - good grounding is supplied; and the switches at the front are already there.

- We propably want to either use the pre-wiring to put some power sockets in the top aera; or under the desk.

- Wash basis could be moved to the side or the other wall and be remounted. OR alternatively - a hole could be cut in the fumehood desk.

- Perhaps put in a very easy to clean bit of vynil. And seal it to the walls to make keeping this room very clean easy. Probably also give walls and ceiling a coat of water-disliking paint then.

Note that the use of 'we' in above is not the royal we - but almost 'you' -- as I'll be on holidays next week :) So would appreciate if folks pick this up. And an ack on the list of the 'urgent' things would be much appreciated!

Thanks all that helped !

Dw.

Hi all,

A very hastily uploaded set of photos can be found here: http://liedra.net/misc/Biohackspace/ I'll endeavour to make it look a little more presentable when I get home from work. 

I've got some video clips but those will have to wait til later :-)

Cheers,
Catie

Great work! Looks excellent!

But do my eyes deceive me? a file being used instead of a chisel? http://liedra.net/misc/Biohackspace/IMG_0518.JPG

There may be a cheaper source, but a quick look around Screwfix
suggests more like £200-£300. So worth hanging onto the old one if
possible.

Ok. I checked Argos - and they are 59 including all the bits around it. But fine to hang on to it - suggest putting it in the other toilnet next door ?

I just got a pipe cap from Leyland and replaced the improvised seal with it, using solvent cement. I've turned off the water in #23 (both pipes) to let this settle; and left a note on the sink to not turn it back on before Saturday mid-day (the glue instructions suggested to let it dry for 24h.)

The water reservoir is in the left-hand toilet in #23, the toilet and sink in the new wet lab.
