Deur Opener v2

Eddy Pronk: Added some ideas, observations regarding unlock mechanism

{{Project
|Name= Deuropener Versie 2
|Status=Initializing
|Contact= cfw
}}

The door opening mechanism on the front door of "De Verlichting" needs a redesign.

It should be somewhat more durable (current mtbf is around 2 months) and the appearance could be improved.

We invite participants to adopt this project.

== Ideas area ==

''Ideas regarding unlock mechanism:''
# We've looked into a winch servo, but with the torque needed they are just as expensive as linear actuators
# Linear actuators are a good option and could be "retrofitted", but still reasonably expensive.
# How about something like this? [http://nl.aliexpress.com/item/ES-130A-130B-Narrow-type-Electric-Strike-Series/505735088.html Electric Strike]. Not as easy to install, however they are cheap, easy to operate and unlock the door instantly. (12V = unlocked, 0V = locked)

{{Project
|Name=UVBox
|Status=In progress
|Contact=user:Eddy Pronk
}}

A cheap and simple UV exposure box for creating PCB's using the photoresist method. The current solution is huge and inconvenient.

The box will consist of a frame, a matrix of UV LEDs and a timer circuit. The solution will be geared towards 10x16cm copper clad boards, and will therefore have a small form factor. For the timer circuit I propose using one of my ATMEGA88's and an LCD module. The box will be powered by 12V and by putting LEDs in series (every 2 or 3 LEDs, depending on Vacross) I hope to keep wattage down.

== Status ==
500 UV LEDs are currently on a boat from China towards the space. This should be enough for at least 1 decent size box and a tanning bed.

Update June 2013: Almost finished soldering the boards. Each 10x16 prototype board contains 12 x 18 = 216 LEDs, and the enclosure will house 2 boards with 432 LEDs in total in a 20 x 16 configuration. For each 3 LEDs (in series) there is a single 68Ohm resistor. Total amperage per board is around 1.4A (observed).

Microscoop

2013-02-26T14:31:44Z

Eddy Pronk:

Ik (smeding) loop al een tijdje met het idee te spelen om een microscoop voor de space te regelen. Idee is dat dit het veel makkelijker maakt om bijvoorbeeld klein elektronicagepruts te doen. Daarom deze pagina, om eens te registreren hoeveel interesse er is.

Wat ikzelf in een microscoop zoek is:
* bin- of trinoculair
* vergroting ergens tussen de 10 en de 40
* liefst op een arm gemonteerd
* genoeg ruimte eronder om ook te kunnen werken met bijvoorbeeld een soldeerbout.

Opties variëren van redelijk goedkoop maar bare-bones (zoals [http://link.marktplaats.nl/628211804 deze]) tot duur maar goed en flexibel inzetbaar (zoals [http://link.marktplaats.nl/645560827 deze]). Meer geld is dus van harte welkom!

=== Construction ===

==== Lego Train ====
* Maxell will bring his Lego train set. Also able to bring regular pieces (might need to sort out and clean them first).
** ~30 pieces of [http://imagehost.vendio.com/a/35097860/aview/4515_new.jpg straight] track.
** ~35 pieces of [http://www.dallasvintagetoys.com/images/products/detail/lego4520.jpg curved] track.
** One [https://upload.wikimedia.org/wikipedia/commons/d/da/IMG_1916_Lego9vMotor.jpg electric train], two one [https://revspace.nl/images/8/8d/Legocontroller.jpg power controller], three [http://www.brickinstructions.com/04000/4531/001.jpg turnouts], etc etc.

==== Geomag ====

=== Games: ===
* consoles
* pinball (including look inside)

== To Dos ==
* Funding (mainly to cover costs of parts):
** Contribution or voluntary onation by participants
** Sell kits for selected projects
** Revspace
** External sponsors?

* Trashman / Willem van de kinderkelder contacteren
* met XNDR de datum vastleggen
* projecten voorbereiden (materiaal, test build, etc)
** Bill of materials maken en een kosten schatting maken
** Als alle bestelde onderdelen binnen zijn een en bijeenkomst plannen tussen Devnuller en Gori
* inkopen

* Final "Enge Dingen Removal" ochtend van te voren.
* Make sure there is an EHBO kit. -> There is an EHBO kit in the handwerklokaal

== Shopping List ==

* all done !
