BTPA-7

 This is my newest project-the BTPA-7.  BTPA stands for bullet transfer pump action.  This gun brings out the new year of innovation, as it is my most innovative and successful gun yet.  It is a bolt action gun, making for superior efficiency, combined with a pump, making for a high ROF.  Unlike other bolt action guns, however, this gun uses a pusher to transfer the bullet to the firing chamber, and also unique to other bolt action guns, the bullet stays there until it is fired, no matter how you shake or tilt it.  Right now I have most of it done, but do not have the pieces for the ram guide, which is crucial to making the gun fire successfully, keeping the ram in tact as it is pulled back.   Here is a video of the bullet transfer system: And here is a video of the gun with the pump (I also removed some pieces that were getting in the way of the trigger so now it works perfectly) Let me know what you think.

7 segment counter

Hi everyone , i have a project that include connecting two 7 segments together to display an input that makes one of them for the units and the other for the tenth but i can't connect them together in a way that makes them count exactly correct as the tenth 7 segment usually starts by 1 whenever we try it and when the unit reach 9 then the tenth gets 2 not 1 as it already started with one  https://www.dropbox.com/s/w50bn9nk8fu7q5s/a7aneeeek.pdsprj?dl=0 http://i58.tinypic.com/1z4eucx.png

How to replace damaged LCD in iPhone 7

Yesterday while getting out of my car, my phone slipped out of my gym shorts and hit the sidewalk. I came to a complete halt and slowly but carefully picked up my phone. "Maybe it got a couple of scratches and that's it?" But when I flipped the phone over, I discovered that it had a bunch of spiderweb cracks. I would like to repair this myself, I found a good video guide: https://www.youtube.com/channel/UCxKlNJ577sGSnZAb5fLPD1g Should I follow this instuctions, I think it is pretty decent job, what is your opinion?

Can someone please help me create a simple 7-segment number display? [see below for details]

Background info : My name is Simon. I'm a member of the Classic Celica Club of Victoria (Australia) that competes in an anual event called the Winton 6hr Regularity Relay. It's a 6 hour long track event with about 40 teams and 6 cars per team. Each team has one car on the track for the 6 hours. Prior to the race, each car nominates a time that they believe they can consistently do for their share of the race (usually approx. an hour each). Points are awarded for each lap achieved that is within 1 second of the nominated time. Points are deducted for any lap that is faster than the nominated time. The thing is THE DRIVERS CANNOT CARRY ANY FORM OF TIMING DEVICE IN THE CAR. The aim : To build a board that clearly displays a 3 digit time. (eg: 1min 56sec).  Team members will time the car on the track and then use the board to display the time for the driver to read as they pass by the pit wall.  (note: this practice is not against the rules). The requirements : The board must be big enough, and clear enough, to be read from >75m away. The adjustment of the board must be very quick and intuitive. (the task of timing is shared around and there's no time to train people to use the device). The board must be light enough to be held by outstretched arms. No timing device is required in the board itself. The time displayed on the board isn't always the time that is recorded. Adjustments are sometimes made for one reason or another. Scrolling through the numbers is fine, so long as you can scroll both up and down. Each digit should be completely individual (ie: not linked). Layout : [see attached images] I was thinking of using a typical 7-segment display layout made up of 79 x 10mm LEDs. The actual physical construction of the board is well within my ability. It's all the circuitry that i am clueless on.  I am a total newbie so please be gentle when describing electronics. I'm new to instructables but i have spent quite a few hours searching this site for answers. The thing i've found is that my device is far simpler than anything posted on here but i'm still too much of a newb to work out how to do it. ps: I hope i have posted in the correct section. Simon.

Laptop with low Connectivity

I have an HP Windows 7 laptop that always had fast internet up until 4 months ago. Its been having 2-3, or sometimes 1 bar now. Im trying to use my personal hotspot but thats not even working. My sister has a Windows 7 laptop as well, uses the same internet and still has better internet connectivity than I do. FULL BARS! I know my laptop is capable of having fast speed too, I just don't know how. I think there is a setting or program stopping it from having better connects.How do I fix this?

The 7 pound bike

The wheels are barely over 700 grams for the pair and weight has been shaved off of every possible spot to create a ride that weighs in at 3,195 grams or just over 7 pounds. Damn. I used to have a beast of a cruiser that was easily over 50 pounds. This bike isn't just for show either. The owner has ridden 1,000 kilometers a week on it! link

7 Layer Cake

My baking skills are not good enough for me to do this on my own, but I'd love to see an Instructable on making a traditional 7 Layer Cake. I was surprised to find it in the supermarket freezer the other day and wished I knew how to make it (at least in theory). It is usually only found somewhere where there is a large Jewish or Eastern European influence and there seems to be fewer and fewer bakeries making it so I'd love to have a recipe for posterity should I ever be inclined to give it a try. It was the first time I've seen it in California (and it was shipped from a bakery in Brooklyn no less!).

7 Color LED Help

I have recently bought two 7 color blinking LED's from RadioShack and learned how to make them change colors and such. I have figured out that if you put a momentary push button switch (with 4 pins) onto the "switch" pin to ground you can get it to change to a solid color then to the cycling of all colors forever. I have two of them set up in parallel, they both start at the same time but slowly become out of sync. Can anyone recommend anything I can do to keep them in sync? I plan on putting these in my car someday as floor lights and it would be nice to have all the lights change color at the same time and not have to keep pressing the darn button over and over again to reset the LED. Any other tips regarding LED's would be appreciated. I am kind of a noob at this so please try and "dumb it down" so I can understand. I am only just grasping the basics of hobby electronics but am very eager to learn more. Actually, any tips in general that any hobby electronics enthusiast should know would be nice.

Driver for arduino on Windows 7?

I have recently had to wipe the hard drive of my computer due to a virus. Consequently I had to re install all of my arduino stuff. I got my IDE arduino 0022, but when I plugged in my board to get the driver again I ran into some problems. First off it came up in other devices on my control panel, and when I tried to update my driver, the ArduinoUno.inf did not come up in the driver folder. I moved the file to its own folder, so that it would actually come up when I tried to update the driver, but even when I selected the file I knew for absolute certain was correct the computer said that there was no driver in that file for my device. What is going on and what can I do?

Windows 7 explorer becomes unresponsive Answered

Sometimes my computer glitches and  I am not able to click on anything that has to do with the windows explorer process (desktop icons, taskbar programs, etc.)  I have tried ending the explorer.exe process, but i cant start it back up again because starting explorer.exe opens an explorer window (my computer, my docs, etc.).  The only way to fix this is by restarting.  Does anyone know how to prevent this?  The laptop I'm on is a Dell XPS L501X (i5 460M, 4GB ram (2x 2GB) NVIDIA GeForce GT 425M (1GB))  I am running Windows 7 home premium 64-bit EDIT:  This problem got weirder...Now it happens less frequently, but the problem goes away if I open Revo Uninstaller (maybe because the UAC message refreshes the explorer process?).  Does anyone know if that is the reason?

3 volt signal to trigger 7 volt? Answered

Ok,so I get a 3 volt signal from a detector and use this 3 volt to trigger an alarm which atleast need a decent 7 volts to function.The detector could take a max. of 5 volts input which I got from the 7 volts DC supply.This 5 volts fed,gets transformed into 3 volts after the detection.So let me make this clear,I have a 3 volt and a 7 volt supply.I need to use this 3 volt to trigger the 7 volt circuit.I know what you are thinking-a relay !right?but I couldn't get  a 3 volt relay anywhere(though I got a 5 volt relay).I can tackle this situation in two ways.1)Either by stepping this 3 volt to 5 volts and making the relay do the job.but how? 2)Or some circuit to use this 3 volt to trigger the 7 volts(like a relay but maybe by using ic's).This is the final part of my project and so please help me.

new to arduino, want to run a dual display for 2 sensors

I'm new to the Arduino community.  wanting to set up a dual radar setup with 2 ultrasonic sensors,  (Ultrasonic Sensor Module HC-SR04), and outputting to a pair of 7 segment displays ( two 7 segment displays each).  I've found a code to do a single could use a lot of help to output two at the same time, basically 2 lanes without 2 units.  im using an arduino mega, ordered a unor3 and hopefully it can be made to run on one or the other. code is as follows: /* HC-SR04 Sensor    The circuit:     * VCC connection of the sensor attached to +5V     * GND connection of the sensor attached to ground     * TRIG connection of the sensor attached to digital pin 2     * ECHO connection of the sensor attached to digital pin 4  */    /*  This is a radar ping sensor that calcultates the speed of an  object traveling away or towards the sensor.

7.1 DIY audio switch, please help

Dear Instructables community,I stumbled on to this site while looking for a DIY solution to a problem where no commercial alternative seems available. The problem? I need a dual input/output switch for my 7.1 audio system.What I found on this site was: https://www.instructables.com/id/35mm_51_Surround_Sound_Switch_Splitter_Box/I'm "OK" with a soldering iron, but I've never really built anything before, and I'm not familiar with some of the terminology. Really, the only things I have done in the past have been soldering plugs on the ends of wires and re-soldering loose connections. Even so, I'd like to build something similar but for 7.1 with dual inputs and outputs.I'm hoping you can help me make the right choices building this.My original plan was going to be just like the 5.1 version with a few most switches, but instead of the input 3.5mm jack as the source for the switch, I would just connect another switch and then connect it to two 3.5mm jacks.(See attached image)Will this work without taking a hit in audio quality?Is there an easier or more efficient way of doing this?Here's the hardware I selected initially:Switches: http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId;=10001&catalogId;=10001&productId;=76260&3.5mm jacks: http://www.allelectronics.com/make-a-store/item/SMJ/3.5MM-STEREO-PHONE-JACK-W/N.O.-SWITCH/1.htmlI don't understand most of the terminology on these parts, but they look like they should work.Please let me know what you think, I'm open to advice.Thanks!

10 bit to 7 segments

Hi everyone!! I'm posting because i need help! I want to make a 10 bit to 7 segments schematic/circuit. I need to just convert 10 bit binary to decimal.. In my idea i have 10 switches and every one of them represents a number in decimal. for example when i put ON my first switch from the right i want that in the 7 segments appears the number "1" and for example when i switch ON the last switch from the left it appears "512" and if all of them are ON appears 1023. So i have 10 ON/OFF switch and 4 (7 segment) display. I have a PIC programmer, so if anyone can help by hardware or software it would be great. Thank you very much!!!

However, I'd like the computer to run the server 24/7 (or until I tell it to stop) I've gone into the power saving properties and changed it so the computer never hibernates/goes on standby/shuts down. I've also made it so that the computer never shuts down the display, or the hard disks. However, when I leave it overnight, I wake up to find that it has gone to it's screensaver, and when I wake it up, I find myself back at the login screen. (Despite checking a box telling it NOT to do that.) Also, when I do log in again, the program running the server has been shut down.  Is there something I'm missing here? How can you make a computer stay wide awake 24/7? I'm running windows XP by the way.

Windows 7 truely sucks

I put Windows 7 pro on my gaming PC, oh my god, it sucks so damn bad! Good thing I dual booted with Vista, I have no clue what everybody was thinking when they said it was good! Every 10 minutes, blue screen on death. Tried everything, removing ram, taking out the video card, changing the power supply, plugging it straight into the wall with out the battery back up, nothing worked, so I booted Vista and it worked great, had it on for 2 days so far. And yes, my computer is very compatible with 64-bit. Windows 7 had a 10 minute maximum. Windows Vista just works, I just wish it had XP mode.

DVDRW is not recognized, Samsung laser printer does not work, USB is slower than 1.0, movies cannot be played properly... Many conflicts, programs often don't work etc... It seems almost as bad as Vista. W7 32b ultimate, AMD dual core, 2 Gb, etc. Is this normal???

Blakes 7 Teleport Bracelet

This is how to make the magic blakes seven teleport bracelet!Ingredients:one cardboard roll, such as a poster or postal cylinder or the cardboard roll from inside a roll of packing tape; diameter 8.5cm, width 4cm (cut to this width if need be, using a saw or knife)cardboard, thick enough to be sturdy, thin enough to be flexiblethin cork (optional)plain paperglueblack or dark brown foam rubber (optional)silver tape width 1.5cm OR aluminuim foil cut or folded to width 1.5cmAntique Gold or metallic brown paintgrey paint OR a round grey button 2cm diameter OR grey tapered paint OR pink paint OR red paint + pearl nailpolishbrown packing tape or beige paintclear or red contact (optional)Visual Reference:Refer to the Liberator Teleport Bracelet diagram in the Horizon Technical Manual.Instructions:Cut your roll to the right width if need be. If the roll is too thin and flimsy, stick a layer of cardboard over it. Cover the rough edges with paper.Cut five strips of cardboard, one 15x3cm, one 9x3cm, one 1.3x3cm, and two 2.5x1cm (measurements will vary depending on the precise size of the cardboard roll). If the cardboard is thin, cut twice as many strips. If you are using thin cork, cut one strip each from the cork also.Stick the strips onto the roll, making sure they evenly positioned in the center. Check the diagram for where to stick them: the two long strips should be next to each other with a small gap representing where the hinge of the bracelet would go if it had a hinge. The small 1.3x3cm strip goes in the larger gap between the long strips - this is where the red button will go. If using cork, stick the cork down first, and the cardboard on top.When all the glue is dry, paint the bracelet with antique gold or metallic brown enamel paint. Do more than one coat if you think that will look better. Wait for the paint to dry.The red receive-button is made from the two smallest strips of cardboard stuck together, covered with white paper, painted red, and covered with contact to make it shiny. Another way of doing this is painting it red, and then painting it with white-pearl nailpoilish to get that glowing pink-red effect. Glue this as indicated in the diagram.The grey transmit-part is made either from cutting a circle of paper or thin card (1.5-2cm diameter) and painting it grey, or by using a grey round button and cutting off the shaft so that it will stick on flat. Stick this on as indicated in the diagram.Cut out silver tape or foil and stick on the bracelet as indicated in the diagram. Cut out (very cleverly) pieces of brown packing tape in the shapes of the alien characters that decorate the rest of the bracelet and stick them on, or else paint them on with beige paint. You may wish to paint the whole bracelet with clear enamel to protect it.Optionally add a lining with foam rubber, to aid the bracelet in not falling off when you wear it.NOTES: Cardboard rolls: the roll from inside a large roll of packing tape comes closest to the right size. A large postal cylinder is too large and a small one is too small. A Pringles packet is too small, but may be easier to obtain. A Pringles packet is easier to cut but is also flimsier; it is recommended to add bulk by sticking on more cardboard to thicken it up.Cardboard: most cardboard you can buy will probably be too thin. The backs of note-pads may provide thicker stuff. The disadvantage of thicker cardboard is that it will not bend as easily, and the cardboard used here must bend. An alternative if available could be thin cork (a few millimetres thick); this will bend fairly easily and add the bulk you need. But only bother if you happen to have some (maybe left over from someone's redecorating or the like). I used it for mine, it worked beautifully.The red button: building this up from strips of cardboard is fairly tedious, and if you can think of a better way, do that.I know Michael Keating!He Played Vila.

I have looked everywhere for solutions.  Could it possibly have to do with the fact that I just installed Drop Box on it?  Thanks in advance for your answers.
