Ok. So you've got an iPhone. You like it. You really like it. A lot. It takes great pictures. It takes REALLY BIG great pictures. So, you load your photos from your Apple Photos app to your favorite picture hosting service and merrily place them into your posts. Then various and sundry people start screaming at you and threatening to give you a proper thrashing because it takes around 3 hours for your post to load for them because your pictures are so big. The BM mods see it, tap you on the shoulder, and ask you kindly to reduce the size of your pictures because they're using up all available bandwidth and nobody can see anything else till your pictures finish loading for all the BM users who are trying to access your wonderful posts all at the same time. All because you like your iPhone camera. What's a person to do? So, you think, "I'll just get into the Photos app and tell it I don't want the bigger pictures. I only want smaller ones." Wait, how can I tell the silly phone that? There's no setting that lets me do that. Sure, I can email them to myself and specify small, medium, or gargantuan but where's the fun in that? I already talk to myself (and the little voices talk back), I don't need to start emailing myself also. Fear not. Your iPhone has the ability to fulfill your smaller picture wishes. Follow along with me in the subsequent posts and I'll try to show you step-by-step how to build a handy-dandy photo size reducer. It's not hard. You might actually enjoy it. And when people ask you where you got that cool app, you can say "I built it"! Mods please feel free to delete this thread if you don't think it's appropriate or helpful.
I'm having a lot of ideas at the moment. The latest is to build a DIY spray booth, (for when I've sorted out an airbrush), but what concerns me are the electrics. Assuming that I've got the right parts - bathroom extractor fan, 3-core, on/off switch and 3-pin plug, does anyone have an idea on how to wire these things up? I only ask, because I'm a simple mechanical engineer and can attach bits together, but have always seen electrics as a bit of a black art.. Any advice would be appreciated.
Notice: Go here to see a later post in this thread to see the final result: http://www.britmodeller.com/forums/index.php?/topic/234991809-finished-homemade-spray-booth-project-an-attempt/?p=2186396 I will have to do some detective work, but I thought I'd start by making this thread. I acquired this nice transparent storage case shown in the image below, and I have 6x used Noctua NF-P12 fans that fit nicely at the bottom of the case. I think I can make this work, but there is one problem that I am not sure how to deal with: Q: How do I power the six 12V (1watt) fans from the 230V power outlet? Presumably this is easy, but I have really no idea. Hopefully someone knowledgeable can chime in and state the obvious solution. That would be much appreciated. Putting on a hose and finishing the rear part behind the fans seems easy, so the power conversion problem is what seem difficult for me at this point. Ah, I forgot to point out the specifications for the NF-P12 fans: DC 12V (unsure if the 'direct current' part is important) Size: 120 x 120 x 25mm Rotational speed = approx 1300 rpm Airflow = 92,3 m3/h = 1,54m3/min = 54 cfm Static pressure = 1,68mm H2O Acoustic noise = ca 20 dB Input power = 1,08 W Input current = 0,09 A 1,54 x 6 = 9,24 m3/min = 324 cfm (unsure if it makes good sense multiplying these numbers by six) 9,24 seem to be double of what a popular spray booth seem to push out, though I am not certain the numbers for these two solutions are directly comparable. *unsure* Edit: Hm, I wonder if the six fans would be powerful enough. The popular spray booth on Amazon uses supposedly a 25W fan, which seem more powerful than my 6,5W setup. Not sure what to think about this. I have a 15cm wide table fan that uses 20W, that one doesn't really feel that powerful to me. Hm, I vaguely recall my compressor having 17L/min airflow, roughly 40-50psi constant pressure, unless I am totally mistaken. Maybe around 9L/min with 25 psi? Just guessing though.
My latest project, a nice 12V static grass applicator. Dead easy to make, you need a few items :- A resealable container... small one cost 40p and the large one cost 90p Handle was made from an old table, real quality table made with ABS plastic legs which were cut up. Switch was a Futaba RC switch. Power supply, borrowed from a Netgear router. It was broken . Honest. 12 Volt DC Negitive Ion generator, this was give to me by Nick off the forum, I'm not sure how much it cost but I think you can buy them online for a few pounds. Fine mesh colander, cost £2 not fitted yet. Untested at the moment, i'm waiting on some crocodile clips to be delivered, one to attach to the mesh and one to the earth wire, hopefully tomorrow they will turn up so i'll give you a full report once done. Fingers crossed that it will work and I don't frag myself I'll keep you updated on how it works. I've seen some of these units sell for crazy money (£130) so hopefully I'll save a few quid. Cheers Dan
