What is up at h4h since Tuesday afternoon – 25 April edition


Kobus catches us up on what has been happening at h4h:

Good afternoon
Ran out of parking again on Tuesday night.. Richard say we should NOT think of building a carousel for cars.. very adamantly. (32 cars the previous week..)
Lee brought some finger food and Rusks  –  
Sorry could not take photo’s lots this week- hands full – got there first… 4mins .. all gone – very tasty. Real home made.

rewind a week from Tuesday…
Hans Chocolates and myself stand outside the Quad copter\balloon room and discuss the uses of 3D printed plastic- with Hans it is ABS. He showed us his lawn mower wheel and a plakkie- The plakkie is flexible and still in R&D. So we start chatting about travel cases.. scroll down

nonamei think there should be a market for OR Thambo proof travel cases…so Hans made a prototype..

have a look at the shell of the case. It is honeycomb reinforced between two 3mm sheets of ABS- all in one print… So this consist of 2 pieces. Weigh 2kg, but very strong- Hans made it.. So still a prototype. Lesson? Careful what you wish for aloud- it just might come true.

And what about a Morgan frame out of ABS?

and myself 3D scanned and printed – Thursday  beer!!!
So remember Quentin’s toy- the laser cutter?

we have learned so much from it already- like dont open when in operation, reading warnings like the fire warning?

noname2So the laser caught alight yesterday… and almost burned itself out. So Quentin will probably rebuild it again soon – for the second time.. 1 stepper confirmed dead. Quentin bought a fire extinguisher and installed it about a day after the arrival of the lasers. No he did not take photos while the laser was ablaze.. :)
But the first rule has not been broken by a member yet- ambiguity  “dont be on fire”… the laser dont count.  Quentin had to read though all of this- So no finger pointing..

Build your own quadcopter – 10 May 2014


ZARCDEV is planning a “Build your own quadcopter” course on the 10th of May 2014 at House4Hack.

Included in the course is the following:

  • Background and some theory of flight
  • What makes it fly and what stops it from flying (the latter is quite important!)
  • How to fly safely and grow the sport (don’t be a dork!)
  • The components of the quadcopter and how they fit together
  • Some soldering basics
  • Step-by-step building the quadcopter
  • Pre-flight
  • Your first flight
  • 1 free flying lesson (learn with a toy copter before you check the cat’s 9 lives)
