automatic wire cutter diy

Probably best that it doesnt strip the wire itself. If the motor could reverse after the strip cut (while holding the strippers closed) the machine could also remove the stripped end. Since the program space was getting tight, I've switched to an external 25XX series SPI EEPROM, sharing the same bus with display and the TMC2130 stepper driver. I blamed my tools or the age of the wire many times, which I now know was just production variation. similar idea). ST7735 driver rewritten, added display rotation functions. The MP1584 based DC-DC step-down module has a max. Alternatively, the fimware can be uploaded after opening and rebuilding the PSoC Creator project: Unfortunately the PSoC Creator and Programmer software is not multi platform and runs on windows only. The type of the stepper motor drive can be set using the jumpers. Mainly just for fun as the project is ideal for learning several different engineering aspects. When I initially tried it with just one stepper motor and a linear ball bearing on the other side, it either failed the cut or tilted and got stuck on the linear bearing side since the top blade was only going down on one side. So as soon as all the components are available you can start assembly the machine. One more pulling stage would solve that problem. Here is the top view of final (almost, the latest version has a few optimizations aroung the ESP module) PCB. PWM is used to generate pulses of required width at frequency of 125Hz, matching the specs of the used BMS-L530MG high torque servo. Valer liked Teaching FPGA parallel computing. If there is a 3.3V voltage detected on the programmer port, the ESP's UART lines are redirected to the programmer header. Of course I could leave it at this stage as it is, since the stepper work does not require any ultra precision. Most DIY versions are of very similar format utilizing manual wire strippers to accomplish the cutting and stripping, but direct servo actuated blades would allow for more options and consistency. MCU tries to read one of the TMC2130's status registers. When youre ready to go, you just slip it off, and its ready to tin. I have always wanted to make a DIY cutter/stripper based upon my years of experience with cable assembly in the EMS world. Flipkart does not represent or warrant that the customer may legally purchase, own, or possess the product. As far as i know, the best and most economic way to get a PSoC programmer today is to get one of the CYCKIT-059 PSoC 5LP dev kits, containing a nice 5LP MCU to play with and a fully featured programmer/debugger: KitProg as a little snap off board. Basically there are 3 process level of this machine like, Input like wire length and wire quantity provided by pressing push button also the real time data can read on 16 X 2 LCD. The wire is fed from a spool to a custom attachment sitting atop a stepper motor, which looks very much like an extruder from a 3D-printer. This is awesome!! Of course, having a PSoC onboard I wanted to make use of the hardware blocks and construct a stepper driver out of a PWM and counter components. Both, the input and output from the extruder use an M6 screws, which are drilled through with a 4mm drill. dude- awesome project and great video. Wire length, the length of the stripped portions, and number of wires to be made are dictated by input to a Nextion 2.8 touchscreen HMI. "InputStateReg" allows software to read the debounced state of the button input. I was thinking the same thing. It is the responsibility of the customer to handle the product with due care and its intended and legitimate use as a tool. If theyre not pre-tinned, which is of course the best, keeping the insulation on them prevents the wire ends from fraying during transit. Andrey Skvortsov liked PERSEUS-9 homemade mobile 6502 computer. b) I actually tried using 1 stepper motor first, but I heavily under-estimated the force it needed to actually go through the whole wire and cut it. The first protype used a simulated EEPROM component to save data directly in FLASH. I admit this method does not work 100% reliably with thin wires like the 1mm solid copper one, hence I added an option to override that function in firmware. Holy snap that is an amazing idea! Using just about the simplest wire strippers around the kind with a diamond-shaped opening that adjusts to different wire gauges by how far the jaws are closed makes it so that the tool can both cut and strip, and adapt to different wire sizes. I am literally going to implement this right now! Copyright 2019 HexeFX. The prototype electronics was built on a home made dual layer PCB using the CY8CKIT-049 dev board, initially the A4988 stepper driver (changed to Trinamic TMC2130 Silent Step Stick), an SPI 12x128 TFT display, 4x4 keypad, MG996R servo (died shortly after), a 35W 15VDC switching power supply and a few other bits and pieces. An old printer is a good source for such diode + phototransistor modules, often used as paper presence detectors. A thin 0.5mm ABS sheet, available at hobby/model making stores makes a nice cover plate. Each block accepts commands and reports back its state, which can be polled by the central "engine". Underneath the servo there is another magnet to attach the cover when not in use. Such device has been on my "someday to build" list for a long time. Sending various byte values creates different kind of "beeps". I'm not sure if the version I found was the newest one, but it suffered from a few problems: While fixing the problems i decided to add a few more features: Here, again, I decided to make use of the highly versatile onboard logic fabric on the PSoC to create a hardware button handler. Like a toilet seat lid that you forget to open before sitting down. Any place that strands crossed over the others was an established failure point. The hardware and the software can handle both drivers. Maximiliano Palay has updated the project titled Bionic prosthesis. I have made a Automatic wire cutting machine using Arduino nano controller board. The wire travels through a tube, which can be shifted left and right via a servo to position it in the stripping or cutting section of the jaws. Long press detection with its own interrupt output. nice job. 128x128 ST7735 display mounted on the main board. The machine runs on an Arduino Nano, with stepper interface is via a pair of A4988 stepper drivers. Getting it to work on Mac and Linux requires using a virtual windows machine (ie. From what I understand its an hardware+software solution. 4 quick access presets for most often used jobs.

It will allow you to pretty much make anything you want :) It's fairly easy to get into as well. I absolutely love it, especially the precision nicking of the insulation without removing it. Think about it a minute and youll understand why. You could potentially get away with using just 1 or weaker motor if you use bigger and sharper blades. Cant tell you the sheer number of times I come across a technology on the internet or real life, and I see a hackaday article about it the next day, Great build and well documented!

It is quite handy to use that value to erase the line using a fast. However, I was curious if I could change the UART baudrate on the fly (well, almost, between fully sent bytes), thus creating an acceleration and deceleration phases. New Automatic Wire Stripper Cutter Crimping Pliers, New Automatic Mini Wire Stripper Cutter Crimping Plier Multifunctionalh Tool. bobricius wrote a reply on PICO ZX Spectrum 128k. PC Palette a Macro Keypad With Limitless Possibilities. I really appreciate that! In addition the input terminal has a small window used with the IR sensor (diode + phototransistor) to detect the presence of the wire. Added a custom symbol font (play/stop etc). idea: connect the end of the wire, in the spool, to ground. Display (128x128 SPI, ST7735) is driven with UGUI library written by Achim Dbler with a few changes and modifications: The 4x4 keypad component originally written by Bob Marlowe (component found on Cypress community forums), required some reworking and fixing. It helps the cut wire pieces land where they should. The easiest way to leave the strands in their natural lay is to use the stripper to nick the wire, then twist the insulation off gently by hand following the twist of the strands just before you use it. Yes, the insulation bits at the end still need to be pinched off, but its a lot better than doing the whole job yourself. Someday I might do it, for now, the device as it is, has proven to be extremely useful. In addition, these bytes can be sent in patterns, creating a crude, yet useful acoustic signaling block (anyone remember ProTracker on Amiga? Optional footprint and surrounding components for the Cypress EZ-BLE module. Learn how your comment data is processed. I like my wires this way. Weve seen a fair number of automated wire cutting builds before, and with good reason: cutting lots of wires by hand is repetitive and carries the risk of injury. Elecia White - for her command console code. Make 10 interchangeable cartridges for different colored wire. I made a cover out of a thick transparent foil formed with a hot air gun. Next step in Lo-Fi vinyl emulation: HEXE Melusine IV. The only left pin I could use couldn't be accessed by the SCB block. Chip tune factory for guitar: HEXE Sound Cartridge. a) It actually works perfectly fine with stranded wires too! The TX ouptut is inverted to make the pulses active high. Check out his label dispenser, a motor rotor maker, and thread bobbin winder. A thicker one could be used to make a new panel completely. Everything installed and plugged in, apart from the main power. Being a one off evolving project, I often tend to overdesign them a little bit. That will only work on the leading end, though. Using another hardware driven CS (chip select) line for the EEPROM was not possible due to routing restrictions. This allows e.g. A DC-DC converter module provides the main 5VDC rail and the 3.3V one is generated with a linear regulator. The stepper driver selection is done automatically at startup. https://www.komaxgroup.com/en/Products-and-Solutions/Products/Cut-and-Strip/. I will definitely borrow couple of ideas from this build. The display i used has a small onboard 3VDC linear regulator. A DTR signal from the CP2102 module is used to auto reset the ESP after programming. Stepper | Servo | Display/GUI | Keypad | Button | Buzzer | EEPROM| Program. I'm using lots of short terminals made of solid 1mm copper wire in my builds. This may actually make me buy a 3d printer Do it! This site uses Akismet to reduce spam. You could have easily tried to set it up to strip with a batch of low grip wire only to get quite frustrated later when your next reel of wire had too high a grip than your design can handle.

This website uses cookies to improve your experience. Really handy! You have allowed cookies to be placed on your computer. If the chip is not present the result will be a 32bit 0xFFFFFFFF value, hence the program can assume the driver used is the A4988, skip all the SPI config routines and set the microstepping via M1-M3 control pins. https://github.com/hexeguitar/AutomatedWireCutter. DIY Crafts New Automatic Mini Wire Stripper Cutter Crimping Plier Multifunctionalh Tool New Automatic Wire Stripper Cutter Crimping Pliers Wire Cutter. Their editor is pretty good too, if you can handle a bit more UART coding for the 2-way-com, you are rewarded with a great GUI that is really light on the C side. Thanks for the sub! (Video, embedded below.) New version of the reVOLVER sampler/looper pedal. After a few trials I ended up using a much simpler and, as it turned out, effective way: one of the SCB components (Serial Communication Block) configured as plain UART. One of the cleaner versions I have seen of the DIY cut and strip machine. Dead Spider Becomes Robot Gripper: Its Necrobotics! By using our website, you agree that we can place these types of cookies on your device. Virtualbox + Win7 or higher). The small bodge wire around the ESP module has been rectified in the final version of the PCB. Write for various publications, including Hackster. Press J to jump to the feed. Additional LEDs and prototyping area on the PCB. The function takes the number of steps, recalculates it into a series of bytes and starts the interrupt driven transfer. Working on my own stripper-bot at the moment! Stripper-bot sounds like a relative of Cherry 2000. This website uses cookies to manage authentication, navigation, and other functions. Nice. More epic projects incoming! Choosing between cutting and stripping is a matter of aiming the wire for different areas on the cutters jaws, which is done with a hobby servo that bends the guide tube. A custom PCB links things together electronics-wise. Implemented, but commented out interrupt trigger. The ESP-12 (ESP8266) module runs the ESP-Link firmware and is used as a Wifi/Serial bridge. When you need to strip a bunch of wire to a certain length, you could bite the bullet and measure manually, then carefully cut over and over and over. Single cut and rewind (remove the wire from the extruder) operations. They were paranoid about reliability, One of the requirements was zero rats-nesting of the wire strands. earned a sub from me. At the 2:14 mark of the video, there is a slow motion video of the cut, strip, and pullback actions; all of which can be morphed into a DIY version. The machine is very well built; It is clear that the author put great effort on the project and made it all worth, but what really catches the eye is the mechanism provided by the servo to displace the wire to either slice or cut. V cut blades used on the machine mentioned below are not cheap though, so a home made version from 2 razor blades might accomplish the same goal. Kustaa Nyholm / SpareTimeLabs for the excellent tinyprintf library. Very cool. It provides a footprint for the module with all the required components and pins available on a header. It also does some basic scripting and calculations, has some variables and the bigger models also have storage for images I think. Those americans. Calculates required wire length to perform the task. A4988 does not have such a feature, thus the fan is turned on when the motor is working. UART is set to 8 bit of data, one stop bit and no parity (8N1). If there is no wire, the phototransistor will produce a logic 0 signal, a wire blocking the light will result in logic 1. Irony for me is I work for one of the top US wire producers, but have no access to that expertise because I work in a different division. Funny story, last week I added wire stripping bot to my project list. Some parts, that are often removed are mounted using neodymium magnets and a piece of ferrotape. DIY Crafts New Automatic Mini Wire Stripper Cutter Crimping Plier Dedso Professional Heavy Duty Self Adjusting Automatic Wire Strip You, the customer hereby represent and undertake that you are of legal age for purchase and use of this product. I was fortunate enough to work in the business for a few years. The plan was to make a base hardware which might be used for other stepper/servo related projects. The feeding mechanism employs a NEMA 17 stepper motor to pull wire through, using a timing belt-style pulley setup thats very similar to a 3D printer filament feeder. Engineer, maker of random contraptions, love learning about tech. Changed the PutString function to return the end of string 'x' coordinate, similar to Adafruits' GFX library. The compiled HEX file is provided in the github repository (/software/hex). It would limit the shortest jumpers you could make, though. no more size adjustments. Detailed view of the IR wire presence detector.
