2017-10-21 Build day

Today we opened 10.00 until 17.00 to prepare for our open day next weekend (27th and 28th).

We are running a Make:Shift:Do open day event in association with the Craft Council on Friday 27th October from 17.00 until 21.00 and Saturday 28th October 2017, 10.00 until 17.00.

The laser cutter was put through it’s paces. After a few adjustments and a modification to the extraction system, the laser cutter was pronounced fit for use next weekend. A set of guidelines for use are here:- https://github.com/lesp/BlackpoolMakerspaceLaserCutter

Tony2 took a series of pictures with a Raspberry Pi camera for testing with photogrammetry software, then went home to set up a better picture taking environment with lightbox and turntable to try again.

Tony1 donated an i7 tower unit as the basis for a workstation to run the photogrammetry software. It will need the Radeon graphics card replacing with a CUDA compatible Nvidia card with at least 1G memory on board, and the computer memory will also need upgrading.

The Colmap photogrammetry software was tested on Mike2 laptop which had CUDA compatible graphics and Colmap was found to be very fast, but a bit of a learning curve is involved to use it effectively.

The 3D printer was found to have a drive belt with not enough tension causing it to slip and loose position while printing. There is no obvious way to tighten the tension, so the belt has either stretched or it is the wrong belt. The manufacturers are going to be contacted for advice on the problem.

The proposed photogrammetry demonstration for Make:Shift:Do is ready in theory.  The complete demo would involve taking pictures of an object, feeding the pictures into photogrammetry software to produce a 3D representation, converting that representation into a file suitable for use in the 3D printer, then printing out a 3D replica of the object we photographed. Unfortunately, with the 3D printer out of action, we will be unable to do the final part of the demo, which is to print the replica.
