Mouse Robot Serial NumberUsing the Raspberry Pis serial port Claytons Domain. The stock Debian image for the Raspberry Pi uses the UART as a serial console. I was able to connect to it from my Ubuntu laptop via my 3. USB FTDI TTL 2. 32 cable. Meet Rolly our first autonomous microbot based on an Arduino Uno microcontroller and our own special sauce software. The Arduino Uno might be an aging 8bit. Hi there, great writeup that is accessible to linux n00bs like me. I wonder if you can help me at all further please I want to attach a serial mouse systems mouse. Mouse is an American surreal humour and psychological thriller animated television series created by Matt Maiellaro for Adult Swim. The series revolves around. Recover My Files V2 91 Download. Mouse Robot Serial' title='Mouse Robot Serial' />Mouse Robot Serial KillerYou can measure from the pins on the connector to the wires inside the mouse. Note which is which before you cut the cable. These wires are most likely colour coded. RobotShop, the Worlds Leading Robot Store for Domestic and Professional Robot Technology. Here you will find robots, robot toys, robot kits and robot parts.

I connected Raspberry Pis ground pin to the ground pin of the FTDI, the Rasberry Pis TX pin to the FTDIs RX pin and vice versa. The Raspberry Pis pinout is available here. Then on my Ubuntu laptop I installed minicom sudo apt get install minicom and fired it up with minicom b 1. D devtty. USB0. After typing in a username, I got a password prompt and was able to log in. Final Cut Pro X Torrent Mac Crack Apps on this page. Also, the serial console allowed me to see all the kernel output during boot, which could be handy someday. But I wanted to use the Raspberry Pis UART for my own purposes, not as a serial console. To achieve that, I did the following. First, I made a backup of the bootcmdline. Then I edited it sudo vi bootcmdline. Originally it contained dwcotg. AMA0,1. 15. 20. 0 kgdboctty. AMA0,1. 15. 20. 0 consoletty. I deleted the two parameters involving the serial port tty. AMA0 to get the following dwcotg. I rebooted sudo reboot to confirm that kernel output was no longer going to the serial port. But the serial console was still available. So I edited etcinittab sudo vi etcinittab. I commented out the following line 2 2. L tty. AMA0 1. 15. Finally, I rebooted again and confirmed that nothing was touching the serial port anymore. Then, to test it out I installed minicom on the Raspberry Pi sudo apt get install minicom. And ran it minicom b 1. D devtty. AMA0. After firing up minicom on my Ubuntu laptop again, I was able to send data in both directionsNow to get the Raspberry Pi talking to an Arduino.

V Regulator Cap for 9. V Battery. For quick portable projects and temporary hacks, it is often faster to reuse a simple 5. V regulator circuit than to integrate a power supply into the device design. My toolbox has an LED tester and magnifier light, so why not add a convenient 5. V regulator cap to the collectionThere are nicer ones on the market that have surface mount components, but half the fun of an electronics hobby is creating something basic in your own style. This double decker board with flashing LED power indicator allowed me to experiment with flush battery snaps and board interconnects. Mercury Battery Replacement Regulator. Several decades ago, mercuric oxide button cells were common consumer power sources. Mercury was phased out due to environmental concerns, leaving behind vintage photographic equipment and watches that were incompatible with alkalines wide voltage change or silver oxides slightly higher nominal voltage. Tinkerers have come up with a variety of solutions for many devices. Perhaps modern technology can address a few more with an itty bitty 1. V low dropout linear regulator. D Printed Spool and Wire Soldering Holder. Buying new wire begs the question of what type of insulation to choose. PTFE is selected since it doesnt tend to melt back as common PVC wire insulation does. The new wire arrives without a spool, which necessitates printing a spool on a three dimensional printer. The spool is easy enough to model but consumes the day with a six hour print time. Soldering the newly acquired wire to another wire is frustrating with the classic misaligned helping hands tool. Thus, old fashioned wooden clothes pin attached to a base become the project being worked on rather than whatever I needed that wire for in the first place. Generating Waveforms with Paper Discs. In a pinch, you can generate square, sawtooth, sinusoidal, triangular, and noisystatic waveforms by playing a patterned disc on a record player or spare motor using a light sensor. An LED illuminates the paper disc, which reflects varying amounts of light into the light sensor as the disc rotates on the turntable see the video for a demonstration. The circuitry is fairly simple and uses commonly found parts. Can you guess the waveform generated by the thumbnail image Resistor Forming Tool. Who hasnt looked at a classic red resistor lead forming tool and exclaimed I could 3. D print this. I took a shot at designing and printing a few variations. The end result is a functional tool with a couple of improvements, but not as crisp, due to the limitations of home fused filament resolutions. Amd Black Edition 9950'>Amd Black Edition 9950. Upgrading Magnifying Desk Lamp to LEDs. Circular T9 LED bulbs are available to replace fluorescent bulbs in desk lamps. LEDs provide a broader spectrum of light, which is particularly important if you are shooting macro photographs, but is also easier on your eyes if youre soldering or inspecting boards. Unfortunately, the commercial LED bulb I received was defective and had a flickering power supply. Hacking in six additional smoothing capacitors and replacing a missing LED solved the problem. Identifying Bad Capacitors. If your consumer electronic device is failing, it is often caused by old, overheated, or defective capacitors. If you open up the case and inspect the capacitors, you may find some that are bulging, crusty, or are lifting off the PCB. Here are some photographs of damaged Cap. Xon brand aluminum electrolytic capacitors found inside failing Samsung LCD monitors. Also included is a photo of a good capacitor that has beneficial goop surrounding it. How Notto Cast and Machine Bismuth. Bismuth is a high density non toxic metal that forms beautiful crystals. Well, supposedly it forms beautiful crystals, just not for me. See examples of clay casting failures and chipped surfaces as I muddle my way through trying to make anything out of bismuth. Sun Tracker Failed Project. Sometimes you gotta know when to walk away which was eight years ago. I dug up this robot that was supposed to emulate a sunflower tracking the sun. Due to a design flaw in an overly complicated analog sensor bus, and general ugliness, this project got literally shelved. Now it sees the light of day, if only to be a lesson to others. Mounting an i. Pad for Desk Based You. Tube Videos. For many hobbies, an overhead shot of your desk or workbench is the ideal view for your videos. This is unwieldy for tripods, but suitable for a desk swing arm. Similar to a desk mounted magnifier light, the camera can be quickly positioned at various distances, and can be swung away when not in use. The single arm does not tend to block room lighting. Take a look at my tablet mount setup, and see how the arms were extended to fit a larger form factor. Macro Photo vs Microscope. Fifteen years ago, I proudly photographed a PCB using an Intel QX3 toy microscope. How well does that old microscope compete against a modern 1. LED ring light, and stacked photography softwareCan such a photo setup match the microscopes 2. In fact, exactly small of details can we clearly see with a modern rig Would you believe 1.

Come closer to hear the tale of The Great Internet Migratory Box Of Electronics Junk. Replacing Broken Tip of IC Hook Probe. Arg The multimeter measurements are wrong because the probe detached from the circuit because the IC hook tip broke, again I go through far too many broken IC hooks to keep throwing them away. Is it possible to 3. D print a replacement tip Is this an opportunity to improve the tip to be more robust Leveling A 3. D Printer. How to accurately set the extruder nozzle height above the print bed when leveling a 3. D printer. Use a thickness gauge, magnet, and a multimeter in continuity mode to beep when the print head makes contact. Includes a trick to clean the tip of the nozzle by scraping it with the zinc interior of a penny. Printed Circuit Board Survey. What features do hobbyists, students, and small shops look for in a PCB manufacturer Do people care about lead freeWhat about board shape and internal cutouts Is board color important enough to offer as an option Find out the results of the PCB survey. PCB Motor Mount. If you dont have a home machine shop or 3. D printer, you can make a motor mounting bracket from a PCB. Printed circuit boards are strong, lightweight, precise, and are easily manufactured. The PCB bracket can then be attached to your project using screws, straight solder, right angle headers, or dual row headers.
