Pivot Collaboration

Many people enjoy keith-kid's instructable on pivot, but because he no longer "pivots", the instructable has been discontinued. I'd like some collaborators, along with me, to produce an other instructable which covers more topics and covers them in greater detail. If I get enough acceptance, I'll make a start, but only if people are happy to collaborate. Feedback would be greatly appreciated.

Camera Stabilizer (Physics related)

I had an idea for a camera stabilizer a while ago which involves some basic rules of physics. I've done some thinking on it and I can't seem to figure out if it would really work or not. It involves two principles: 1.) Torque (t=f*d) 2.) Inertia (p=m*v) ---- The idea is to combine a gimbal design found on camera "gliders" like these: -Commercial product: http://www.bhphotovideo.com/c/product/521721-REG/Steadicam_MERLIN_Merlin_Camera_Stabilizing_System.html -Homemade design: http://www.diycamera.com/stabiliser/index.html ...with some sort of see-saw to counter the effects of up-and-down motion.  Ignoring the fact that this might be somewhat hard to hold such a thing, I just want to know if this would work. ---- Any balanced see-saw will have an equal amount of torque on either side of the pivot point. Therefore, a balanced see-saw will work with 500g hung 10cm from either side of the pivot point, OR 750g 5cm from one side and 250g 15cm from the other side (750*5=3750; 250*15=3750).  With this concept, I thought of designing this part of the stabilizer like a small camera jib (http://en.wikipedia.org/wiki/Jib_(camera)). That is, the camera on one end with a counterweight on the other. The pivot point would have a handle or some kind of vehicle mount on it.  The stabilization occurs (or so I'm thinking) because of inertia. Inertia=mass*velocity. So, when the pivot point (the handle) moves up or down, one of the sides of the see saw should move up faster than the other. The side that moves up slower (the longer side of the see saw, I'm thinking) should have the camera mounted to it.  ---- Is there a flaw somewhere in my thinking? THE QUESTION: Would both sides of an uneven length, balanced see-saw move up at the same time when the pivot point is moved up or down? I'm not really sure and I'd like to hear your input.

Help with building a sphere made of wood.

I'm looking to build myself a globe but I'm having a little trouble. Most globes today have a single pivot that lets you rotate the globe along a single axis. I'm looking to build a globe/sphere that will allow you to rotate it 360 degrees in any direction. My grandpa used to have a globe that didn't have any pivots and that had a stand that you could place the sphere/globe on and you could rotate it anyway you wanted. I haven't been able to find anything close, and his got burnt down in a fire. I don't foresee the base being a problem, but I haven't really built any spherical shapes with wood as of yet and I am hoping you guys might have a few tips to help me on my way. I figure I should start with creating a skeleton of a sphere using at least three interlocking rings and go from there and see how sturdy it is. Any insight or tips are much appreciated.

I have drawn what i was thinking of designing, i am not particulaly good with google sketch up, i would use an engine with a horizontal drive, 10- 20hp probably. i would have an idler on the belt connecting the front and back axles. i would like to set up a pair of belts to go from the engine to the first axle, both with an idler that can be used as a clutch, it would have one belt for forwards and one for backwards, it is likely to be controled by a second clutch peddle, one forward, one backwards. has anyone got any surgestions, especialy for the pivot. I have limited tools, parts and time, i have only acess to tools we have on the farm, drill, welder, grinder and some hand tools.  I'm nearly 15, so the design needs to be fairly simple, but i will get dad to help with some of it. we have a fair selection of old parts, at the farm, i will probably get 2 garden tractors to start from, two westwood?

Solar deathray smelting? Answered

So Im not sure of the capabilities of the fresnal lens in terms of maximum temperature but I've seen them melt brass. I was thinking with a solar death ray on top and a charcoal fire on bottom that I could get temperatures to melt steel. I have drawn a rough sketch of the overall Idea I really need someone to further refine this idea into a working schematic that I can create when I do I'll document it all and relay the results on here to help others recreate it. Now This setup will be behind my greenhouse on the corner of my property on the side that would be hidden from the sun, however if the base pivots on an axel I'm thinking of using, then it will be able to catch the sun from all the points when it's most useful. In that I'll also have the fresnal lens on a pivot bar to help get it on my focusing lens which will be a plastic and water style parabolic lens my only concern is that if I can't turn that lens will it hinder my project entirely or will it be fine, plus I'm not sure about focal point on this kind of lens. On the sides of the frame I'll build for the fresnal lens I'll have strings attached for turning on the bar and I'll be able to lock it in place to keep from fires around my smelter.. Hopefully! Overall dimensions may appear small in the drawing but the fresnal lens should be at about I'm guessing at roughly 25 feet off the ground, or roughly 7.5 meters and the focal point in the middle will be found and adjusted to the fresnal in terms of height. I think it was roughly 1 meter so I'm not sure entirely I would love some feed back on this idea as I plan to make a smelter with it to complete my in progress foundry I'm building in my shed.

Is there something wrong with my new Leatherman Wave? Answered

I've never had a Leatherman before or a large multitool (Wave replaced a Gerber Dime), so maybe this is normal, but it is really stiff to fold at the pivot points. Some people say that it just needs to be opened and closed a lot to loosen it but I would like some advice. I haven't oiled it yet but I'm not sure what kind of oil to use. The tools and knives are ok, they don't require much force, but I am surprised by the folding action. Is the folding action supposed to go different ways? From the pictures I included, sometimes it goes to the right and sometimes to the left.

Switch Design Issues?

Okay, so I've been working on a prop for a Team Fortress 2 Medic costume, and I've run into a fairly major problem with the wiring of the Medigun. I have everything figured out, except the triggering mechanism for most of the LEDs. In-game, the "trigger" is a pivoting handle, such as one that operates a valve on a firehose. The problem is that I have no idea how to find/install a switch that will activate when the lever (indicated below) is pushed forward. I'm still trying to decide how to install the switch, but as long as the switch is active through a given angle, the installation shouldn't be too difficult to negotiate. Another problem is finding appropriate switches with low actuation forces, but that's an entirely different issue. So, where could I buy that sort of switch, or barring that, how can I make one that will hold up decently well? Thanks in advance!

Homemade player piano

So I got two pianos for free, one in great condidtion other than being out of tune and having a stiff action, and the other, a player, having a badly cracked soundboard and pinblock.  I salvaged the player pneumatics and bellows from the player and managed to mount it upon the other piano.  On each note bellows there were rods that pushed on levers to trip the action of the player piano.  On this one, these levers are about a foot and a half above the bottom of the action, because it is a console piano (shorter).  I've tried linking the bellows to the keys with hooks (which didn't work, it just pulled the keys off the center pivot point) and directly to the action, on the bridle strap hook.  I've tried different strings and two different gauges of wire, but they always seems to stretch, untie or to come unhooked whenever a note is triggered with the player, or with the keys.  If anyone has ideas on how to link the player mechanism to the piano action, any help would be appreciated.

Help make a quacking noise in a wooden toy duck (mechanically, not electronically)

I'm in the process of recreating the LEGO wooden duck toy. I'm only working from a few images I've found online, however; I don't have an actual one to examine. On the originals, the axles operated a couple of mechanisms: the duck head pivots to open and close the beak, and there's a mechanism under the base (I'm assuming) that makes a quacking noise. I've got a pretty good idea how to create a simple cam for the head/beak movement, but I'm not sure how to generate a quacking noise mechanically. My online searches have proved fruitless. Does anyone happen to have one of these vintage LEGO ducks and is willing to snap and share some photos of the mechanisms? Or, does anyone have any good ideas how to make a quacking noise mechanically? My thoughts are a push/pull rod-type crank attached to an axle, but on the other end of the rod . . . not sure.

Real-Life X-Wing Set to Fly

No, really.Andy Woerner and his crazy rocketeer friends have built a 21-foot long X-Wing model that can actually fly. Yes, this is a real X-Wing powered by four solid-fuel rocket engines complete with radio-controlled moving wings. It blasts off in California next week, and we talked with Andy about the project, and how they expect it will do. The X-Wing model is huge. At 21 feet long and with a wingspan of over 19 feet it is, in fact, big enough to fly a kid in. However, knowing that it will be powered by solid-fuel rockets, they wouldn't put a kid, dog, monkey or Gizmodo editor inside, even if it uses three full parachutes to land.After drawing the plans using CAD software, Andy's team and his friends at Polecat Aerospace (with the help of RMS Laser and Aerotech Consumer Aerospace) used laser cutting to make the pieces out of Baltic Birch wood. They also used solid aluminum for some parts, like the rods which are the pivot point for the wings. full story with more pics

Open-Source Warfare

Open-Source Warfare is an IEEE Spectrum article discussing how information technology and the internet play a pivotal role in accelerating the adaptation of individuals against organizations through asymmetric warfare.Robb calls this new type of conflict "open-source warfare," because the manner in which insurgent groups are organizing themselves, sharing information, and adapting their strategies bears a strong resemblance to the open-source movement in software development. Insurgent groups, like open-source software hackers, tend to form loose and nonhierarchical networks to pursue a common vision, Robb says. United by that vision, they exchange information and work collaboratively on tasks of mutual interest. The reliance on IT also enables open-source groups to identify and respond to problems much more rapidly than a more structured, top-down entity can--be it the Pentagon or a large software company such as Microsoft. According to some estimates, it now takes Iraqi insurgents less than a month to adapt their methods of attack, much faster than coalition troops can respond. "For every move we make, the enemy makes three," U.S. Brigadier General Joe E. Ramirez Jr. told attendees at a May conference on IEDs. "The enemy changes techniques, tactics, and procedures every two to three weeks. Our biggest task is staying current and relevant."

Tire Tee

I want to make a tire tee for my softball-loving daughter. I saw the one in the link below and thought it would be an easy (and cheap) DIY. http://i44.tinypic.com/9tzol5.gif I'd want it to be portable, as her team is talking about practicing inside a school gym when it gets cold and this would be an excellent tool for hitting inside. My thought was to fill a bucket with concrete and stick the pole in it which would be my base. It looks like there's some PVC slipped over the pole with a pin/screw/bolt holding it at the height. If I want to get really fancy, I can drill multiple holes and adjust the height for each girl. The weight of the tire should provide enough resistance on its own. I want to limit any extra resistance from the tee as much as possible. The question I have is about the pivoting tire. What's the best way to set that up? I could have two pieces of PVC connected by a coupler and the tire would rest on the coupler. Or I could secure the the tire to the PVC in some way and when the batter hits it, the tire AND PVC rotates around the base pole. Any suggestions about this? I appreciate any insight! Thanks!

Circuit for a simplified DIY galvanometer?

I'm putting together a DIY performance lighting show set as a project and I'm currently working on the laser aspect of it. I've looked into the Galvanometers, which are used in laser shows and those units go anywhere from $60 to $200 a pop. So One thing is that I don't need to create any advanced imagery, I just need to vibrate a mirror at a fast enough rate in order to make a laser spread. My current solution is this: https://imgur.com/a/Cb6ev Basically a small motor pivoting a mirror along the axis. What I am wondering is, is there something more suited for this that isn't a motor or an expensive galvanometer. I've seen people attach a small speaker and supplying a pulse signal to make the speaker membrane rock back and forth. The volume of the sound would control the amplitude of the vibration but the downside is that it's actually audible, even more so than the motor. I remembered this episode of ElectroBoom, where a coil wound around a hollow cylinder would produce a magnetic field which would pull a metal object towards the center. https://youtu.be/mdZo_keUoEs?t=1m54s Before I would go off trying to attach a metal rod to a spring and repeatedly turn the electric magnet on and off to simulator osculation. Perhaps people would know of something like that which already exists?

Would mounting a TV inside a piano damage the TV?

We have an upright piano, and we don't have a good place to put our flatscreen. My thought is to put the flatscreen inside the piano. I have measured for clearance and it fits quite neatly. My only concern is if the vibrations from the piano will somehow damage the TV's electronics. On the one hand, the TV has speakers and generates a dynamic range of sound and volume and does just fine. The TV can get louder than we ever play the piano. On the other hand, the piano sounds are fuller and maybe vibrate more than the speakers in the TV do. More details: The vertical board behind and under the keyboard has a latch that is opened so that the board pivots down and forward.  The TV would go inside the space behind this board. It would make the TV close to the ground, but it would be more convenient than the current location. The space in the piano has a depth of about 6 inches. I would install a piece of 3/4 inch ply across the back to mount the TV to. It would be right in front and possibly touching  the sound board and the bass bridge. The TV is 4.5 inches deep at the deepest point. I am sure that the construction is feasible and well within my abilities. I am unsure of any danger to the TV from such a setup. Any insights, references or suggestions are well appreciated.  Thank you, Michael Moore

MakerBeam Crowdfunded Open Source Building Kit

MakerBeam is a project to build a toy and tool for the open source imagination. Based on Mini-T, a new open source standard, MakerBeam will develop a construction toy for our times: open source precision hardware equally at home doing desktop fabrication or serving as a drawbridged castle for action figures.The fully developed MakerBeam line of connectors will make for an unsurpassed builder's toy and maker kit. Connectors, pivots, hinges, pulleys, cables, wheels, slot-in PCBs, and ALL of it open source, with the models published under Creative Commons licenses. Mini-T is a scaled-down version of T-slot, a building system widely used in automation, prototyping, and machining. This miniature building system will bring the strength and precision of T-slot to a modeling system, allowing serious robotics, CNC machines, and more to be built at a desktop scale. MakerBeam is being built now; we are raising funds and building our Alpha and Beta teams through Kickstarter, an innovative site for crowdfunding. We are nearly 80% of the way to our funding goal, and every extra dollar we raise will go to improving the project for public release, aiming for Maker Faire 2010.For more details including 3-d video of MakerBeam in action check out our Kickstarter page. Alpha kits, which are going fast, ship by Christmas, while Beta kits are projected for February. For even more info, and to contact, stop by the main site.

where can i buy a remote controlled stepper motor kit , that i can use to controll an esc?

Hi, i am building an rc tank, and have decided that i want to put an electronic speed controller on the tank to control the speeds of the two motors used for both steering and driving. however, i am having difficulties finding a stepper motor i can control via remote control, ANYWHERE!!. i need to get a stepper motor, so that i may control the esc, as the only esc i can get without paying more than $30, and will work at the current i am using, needs me to turn a knob to determine the speed, that knob, i will be turned by the stepper motor. now what i have in mind is that i have two kits foir controlling the stepper motor, both i will put onto my remote controller board, so they act like a gear stick on a car, these will control the speeds the motrs go at when i use the on /off signals from the remote control to the motors. what i am asking is where can i get a kit that will wirelessly control a stepper motor, using a band that isnt 27mhz, 40mhz, or 315mhz. but the thing is i dont want aan esc that can be directly controlled by a receiver, as i also plan on using that kit for something else,  as i may just decide to use it to pivot a wireless camrea that is mounted on the tank.

Folding coffee table?

Hi instructable community. I am currently graduating, and I own a 484sq. feet (45m^2) apartment. I have the basics and am quite grateful for what I have. however, I belive that a coffee table is almost a necessity. The problem is that if the table isn't wide enough, it won't be of much use, and if it's too wide, it will occupy too much space and will be in the way. That's (hopefully) where you brilliant minded people come in. I was thinking about a folding coffee table that will be thin, and when I have company over, I pull on it or something and it widens up so it can comfortably hold a few glasses and maybe a book or too. I have added a few images of the area that the table will go. The couch is 2m in length (6.56167979 feet) so you can get a generall image of the room. The couch is on a slight angle, so the small plant can fit behind it (it's on a chair so it can get sunlight),  so I can move the couch around a little for a bit more room. Please keep in mind that I do not have many tools, but I know how to work with raw materials, It will just take a little more time (instead of an electrical saw, I have a hand saw. Same job, takes longer). Also I don't have alot of spare money and I can't find "special" items (for example, ball bearings, and pivot and swirlly stuff are out of the picture). I know it sounds quite bizzare but I would like some help. It doesn't HAVE to be a foldable table, but I would prefer it to be, because the couch is also a bed, so if someone comes over for a couple days, I need to be able to "hide" the table to open up some space.  Worst case scenario, I'll make a small(ish) chest that will double as the table. Thank you for your time reading this message. I will be glad to hear from any of you!

TheDunkis's Display and Request Thread

Alright I'm not saying I'm special enough that I should have my own little personal thread dedicated to what I do but...I'm lazy enough that I should have my own little personal thread dedicated to what I do. Why? Simply that. I'm lazy. I don't feel like making a thread/slide show for any new gun I make but I don't want to post it in some other random place. I also don't want to go around asking for ideas whenever I'm stuck. So to put it simple I'm going to display whatever current projects I have here and I'll also take requests. ~Current Project~ FKG (Folding K'nex Gun- Yes very original...) Alright I saw SK's FMG and I wanted to try one out myself. It didn't end up as pretty or as functional as SK's but it is compact and in a very early stage of design. I'm not sure what to do with it because it's at the point where I'll have to completely butcher it to improve it and then that would require whole new ideas on getting the parts that do work to keep working. So as said the only real big difference here is that it's more compact than SK's. Some other differences are -Held in place by a "grip" rather than a "bolt" -At the moment not rubber band loaded -Simpler trigger -Double hinge thingy for the stock to gun connection. So instead of a fixed pivot swing, two different areas rotate to move the stock from the very bottom to just behind the gun. Otherwise it was to fire dark greys with greens as well with a hopper but right now it doesn't work so well. I think the barrel has some friction in it from the way I set it up. I could loosen it up but I'm just going to redesign the gun anways. Should I continue? Or shall I try making a bolt action gun similar to Zak's (but different enough)? Or I'll try something completely new.

Bizzare Google Earth images of my home town.

I was fiddling around with google earth the other day when I realized that I've never looked at the area around my home town in Nebraska. I dialed in the coordinates and pulled up the satellite images, and what I found was so profoundly strange that I felt compelled to share it. What you are seeing here are topographical images of prairie land and cows. The land consists of small rolling hills of dry grassland, and as you can see, the only landmarks to speak of are the cattle stock tanks. These tanks are essentially circular, large, metal, outdoor swimming pools, some as wide as 30 feet across. The tanks are placed on some of the higher hills with a windmill powered pump to keep the tank full of fresh water. Cattle are then let loose on the land to graze on grass and drink from the tanks. Over time the cattle wear down paths in the grass leaving only dusty trails concentrated around the tanks. I am speculating here a bit, but my theory is that rainfall then follows these trails down the hills and creates the strange, vein like lines through the grass. I don't know how long the area has been used for keeping cattle, but my father grew up here and will be able to tell me more later. The final image is of the developed farm land a little closer to civilization. Most people don't know this, but Nebraskans are really into pie charts. Ok, that may be just me, these are are the patterns left by automatic springler systems. They are literally "crop circles" as corn and sugar beets are only planted within the area that the center pivot sprinkler can reach. PS: These stock tanks are ripe with salamanders, but I still have yet to learn how they got in tanks in the first place? It's too dry to walk to the tanks, and they are pretty far from natural water anyway. There is a massive aquifer underneath all of this, maybe they get pumped up into the tanks? Can salamanders live in aquifers?

Ultimate Frisbee Lite.

Ultimate Frisbee rules run to twenty pages, so I came up with this for my classes. I thought I'd share it, but I couldn't see the point in posting an Instructable when my school's rules require written permission from every parent involved before pictures of kids go online, so I just took advantage of Rachel fixing the topic-posting bug. Indoor Ultimate Frisbee Lite (“Indoor Lite”) 1. The play's the thing: all players and observers must keep to The Spirit Of The Game. Teams shoukd self-referee. If any dispute requires a decision by a bystander or observer, that decision is binding. 2. The game may be played with and disc agreed upon by both team captains. 3. Teams of up to 8, with a maximum of 5 players on the field. 4. The game continues for either an agreed length of time, or to an agreed score (for example, “first to five”). 5. Before play, team captains agree the end zones and playing field, and choose ends to defend. An indoor game has no “out of bounds”, and play continues as normal if the disc bounces off walls, ceiling or fixtures in the room. 6. When the opposing team gains possession of the disc, it is called a turnover. 7. Ultimate is non-contact sport – intentional obstruction of, or contact with another player will result in a turnover. If a turnover is the result of a rule-break, the disc is handed to the nearest opposing player. 8. At the start of play, each team gathers in their end zone. One captain throws the disc towards the opposing team. Nobody may enter the playing field until the disc passes the half-way mark. 9. A point is scored when the disc is caught in (or above) the opposing team's end zone. 10. After a point is scored, all players return to their own end-zone, and the player who caught the disc to score the point throws the disc to re-start the game. 11. A player in possession of the disc may not move, but may pivot on one foot. “Travelling” results in a turnover. 12. The player in possession of the disc must throw the disc within five seconds – any near-by player may count to five out loud. Holding the disc past five seconds is a turnover. 13. If the disc hits the ground, possession passes to whichever team did not touch it last – if team A throws it and nobody catches it, team B gain possession. If team A throw the disc, team B block its flight and it then hits the ground, then team A regains possession. If team A throw the disc, but team B catch the disc in the air, team B gains possession and play continues. 14. If two players catch the disc, whoever caught it first gains possession. If two players catch the disc simultaneously, a single round of rock, paper, scissors determines possession. 15. Unlimited substitutions may be made after any point is scored. House Rules. Because Indoor Lite can be played in a wide range of venues, typically school gyms or halls, some “house rules” may be developed, such as “if the disc goes through the basket ball hoop, that's a point as well” or “if the disc falls behind the vaulting horse, possession turns over and everybody goes back to their ends to start play again”. Before play begins, any new or visiting players must be made aware of the house rules. I also blogged this.

SRV-3 The Concept Review with JBG's SRV-3

Hello fellow iblers’! I’m JonnyBGood and today I decided to post a review of the SRV3 concept. Be sure to note that this is not KILLERK’s official version but a close knock-off. I did not use the same bands or the exactly same mech. I also did not make side covers or the monopod so don’t judge his version based on my model. I also never shot it outdoors so ranges are a complete guess, but I will say KILLERK’s ranges are very believable since I witnessed them at Knex War 2013. So now with all that gibberish out of the way what exactly am I reviewing? Well I’m reviewing the concept, the ratchet mech, trigger mech, and any other part that contributes to the guns function and ergonomics. Okay so now let’s start with the ratchet… Ratchet- After the first use of the gun, I couldn’t imagine trying to load the gun without it. I did try loading it without using it and ended up spontaneous launching it in random directions, something you don’t want to happen with a gun this powerful. (Luckily the wall I hit was cement) The ratchet concept is really what makes the gun usable for people of any age, height or strength so I definitely think KILLERK did a great job designing this feature. Trigger- Well I willingly admit this part is the most different from KILLERK’s version, but it does rely on the same concept of the round being held in by a clamping force. I was actually the most concerned about how this would work because to me holding back a force that could send a yellow rod through a door with a clamp didn’t quite make sense to me.  I will saw after building it I now don’t doubt the clamps capability to hold the round, and now it also makes sense as to why he used a clamp. The clamp trigger mech allows for a very light trigger pull due to the pivot point being so close to the ammo, so the slightest pull moves the clamp up.  SRV-3 trigger is definitely one of those surprising concepts, being that the most powerful gun on instructible’s has one of the lightest trigger pulls I have ever used. Random other things- The ratchet and trigger were the two concepts which to me stood out the most for the SRV-3 concept but there are many other things about the gun which I will cover here. The Handle- So surprisingly enough it is actually pretty comfy, and it’s mainly built to hold the heaviest knex gun I have ever built. On the other hand, I wouldn’t try lifting this gun by just the handle, but why would you? You are definitely not going to akimbo these things unless maybe the handles were moved more toward the front of the gun, and then held like an RPG, but again why would you even want to akimbo or hold it with one hand? It’s a sniper rifle! The Dimensions and some other random things- Alright I bring dimensions up here because I think it’s one thing to see pictures and another to actually know how big this is. If you stand it on end it’s about six feet tall and it’s a yellow rod wide, so ten layers wide. (if you filled in the center which you would not do).  Again as I ranted about earlier this is what makes this gun so heavy but it’s required for the amount of power it’s capable of. You would also add another two layers if you wanted to make it more presentable so it could be 12 layers wide if you want it to be. Another thing that I noticed on my version was that the gun bows toward the end.  Granted I’m not sure as to why or if I was missing a support somewhere but it wasn’t a problem just something I noticed. The only other thing I was planning on reviewing the accuracy but if anything was relevant it is that I suck at shooting accurately! XD I can’t even shoot guns I build accurately so, a guy who is much better at creating coverfire, will not be giving an accuracy score. I will say the sights allowed me to shoot a 8 ½ by 11 sheet of paper from ten to twenty feet relatively easily, so they do help. In conclusion I would recommend you build the SRV-3 if you have the pieces for it. I would especially recommend it if you haven’t built one of KILLERK’S SR’s before because the power will blow you away. It is deffinitlly the king of the slingshot platform for now and probably until an SRV-4.   ( I apologize for the poor picture quality but it would not fit in my normal picture taking spot and there's still too much snow outside for outdoor pictures. Sorry!)
