Introduction: Spinner Motorizer Homemade
goes from half second to 10 second exposure. i finished this shortly after lomo released their official one for silly money, they went wireless, i went adjustable.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: You Get the Idea.
lead for stability, 10 battery's, can use ac adapter, went for a slider pot insted of rotary, remote control is from part of zenit shutter and car phone charger. rubber band drive pully made by friend with access to lathe, i tried a diy but it was a bit naff.
early prototype tried adding a light but it was most ineffective, the project was shelved for a while 23march 2011. incidently having batterys on top and light on front balenced well so high speed could be used
Step 3: What the Spinner Does
first image 10 second exposure caught the entire blackwall tunnel
second image turning slowly by hand not the smoothest action hense iffy exposure values
third image normal use but then polar coordinated in photoshop (thats an instructable in itself, im meaning to show a good technique at some point)
Step 4: Loosen This Screw to Get Handel Off
Step 5: Get Sizes Right
the pully wheel, and the flat side spindel
t tried modifying an existing plastic pully wheel from a sash window (size close)attached to nut and bolt put in power drill and file, went a bit oval so i got al at the toolmaking department to adjust a al-u-min-ni,um cam belt pully (also from mfa, was part of the 1st prototype)
i got the flat sided spindel a bit wrong permanent attached to gears so a screw in base of spinny bit keeps it level
Step 6: Sockets for Remote and External Power
best not mix em up think i got the jack socket cut off terminal right, normaly used to cut speaker on audio devices when headphoning
Step 7: Speed Range
rpm devided by 60
approximate (changes) length of 360 photo neg devided by width of image slot
think this is formula i used, i just wanted a rougth idea what to engrave on the box
Step 8: The Box
its a money box the slot came in handy ,needed lengthening to accomodate slide resistor
Step 9: I Bought the Gearbosx From Mfa 3000:1 Ratio
they got website, they hour drive from me,they in big black barn with shouty dog, i wanted to get touchey feeley with the products, quality box forget the price 4.5v to 15v ,i took plastic cover off to help fit and i like the look
Step 10: Pwm Speed Regulator
parrently better than just a pot, it uses a chip and pot , i swaped the twisty type with slidey type, then i thought can it go slower, so i pot random resistor in series used switch to cut it in out circit to maximise speed range
Step 11: Slider Does Same Thing As Twisty ,
3 wires used meter to figer out
Step 12: Some Wires to Connect Everything
Step 13: 15volts Worth of Batterys and Some Lead to Keep It Steady
well i had to use the lead for somin
Step 14: Nice Gears
Step 15: Super Pully
its epoxted to the box and the gearbox pully goes through the middle, can you see the leveling screw mentiond elsewhere
Step 16: The Slot
just incase you were wondering what i was on about
Step 17: The Light Component Remains From Prototype 1
maybe one day....
Step 18: And of Corse the Remote Control
with a 3.5 to 2.5 jack adapter i could use the one from my canon dslr! ha,
