[OpenTRV-dev] intro

Hi

are the 3d printers homebrew? i was thinking that and bad build... or that people does not take enough care of them?

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

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



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

/bo

Hi,


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.


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.


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.


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.



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.
