<DIV>ours are locked in a room and they keep log who has used them when... the
room/hall we have are at the local uni so we are not the only ones that use
them, hence i think i can rely on at least 2 of them up and running... its
makerbots 2 i think... the 3rd i forgot to note name on</DIV>
<DIV> </DIV>
<DIV>common for all 3 is that they accept a sd card... small lcd and
buttons</DIV>

<DIV>The hackspace-owned ones have been mostly kit-built, and suffered from
inadequate care and over-enthusiastic fixing. It's quite a big hackspace and not
very easy to enforce good practice. The most reliable, mechanically, was an old
Stratasys but the extruder died and a replacement (based on reprap components)
seems to be taking a while to get completed.<BR><BR></DIV>We've recently got a
lulzbot that hasn't broken yet, but I wouldn't want to rely on that
indefinitely!<BR><BR></DIV>Agreed about temperature measurement at the ceiling.
Unfortunately it's also the best place for a movement sensor. <BR></DIV>

<DIV>Hi</DIV>
<DIV> </DIV>
<DIV>are the 3d printers homebrew? i was thinking that and bad build... or
that people does not take enough care of them?</DIV>
<DIV> </DIV>
<DIV>anyways i got access to 3 3d printers... on top of that a
pick&place... reflow oven as soon boards to control my toaster oven is
here... last bit yet to order in a bit is a solder paste dispenser</DIV>
<DIV> </DIV>
<DIV>tried stencils but the setup time is prop more than it would be doing it
manual... also the paste got smeared out under the stencil</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>i know damon is playing with a sensor to detect occupancy.... but i would
not place the stuff at the ceiling.... all the hot air goes up there and it
would be the wrong place to messure temp... a microwave sensor and then
messure at more normal hight... say arround chest hight a bit away from
radiators so you dont get false readings</DIV>

<DIV>Hi,<BR><BR></DIV>I've just sent a join request to the list admin after
seeing Damon's pitch at the Connecting Homes event. I've been looking through
some of the list archives and have probably missed a few things, but am
wondering if I can help out with some parts.<BR><BR></DIV>I'm a member of
London hackspace and have access to the tools there. Items that may be useful
are an envronmental chamber, a laser cutter, a 3d printer and a reflow
oven.<BR><BR></DIV>It's fairly common for the 3d printer to be broken, but
there's also a group based near reading who have well-developed printers, the
thames valley reprap group. These might be a useful resource for getting small
quantities of prints made. Given how much effort seems to be involved in
keeping 3d printers working, this might be more efficient than buying the
Maplin machine.<BR><BR></DIV>I've personally got some SMD equipment - small
irons, hot tweezers, hot air, microscope. I don't have reflow or paste
equipment yet, though. There are a couple of people at the hackspace who have
done more with stencils and dispensers.<BR><BR><BR></DIV>I was at the
Connecting Homes even in connection with an energy-managed house project. This
also requires good occupancy sensors and we're looking at a crude thermal
imaging camera. We think there might be a case for making a ceiling-mounted
occupancy sensor with light and temperature sensors and I'm wondering if this
could share some development with your
plans.<BR><BR></DIV>-adrian<BR> <BR></DIV></DIV></DIV>
