You can test your modified K'nex motor by turning the K'nex motor switch "on" in either the forward or reverse direction and placing anything conductive wire, alligator clip, etc across the two foil fingers.
You can now re-install the K'nex motor into your motorized K'nex project. For our example, we're using the Ferris Wheel build from the basic 35 Model kit. You're essentially done with this build and ready to add your own external controller, switch, or whatever you want. But for completeness, we will show you how to connect an Arduino controller.
A complete kit of parts can be purchased here. The LCA is a really easy to use solid state relay. It requires 1. For this reason, you will need a 1K Ohm resistor between the Solid State Relay and your microcontroller's digital output. The Circuit Playground Classic is an Arduino with all sorts of sensors, digital and analog inputs and outputs, switches, and colored LEDs already built into the board.
You simply select the program function you want and you're ready to go. If you are using another controller arduino, raspberry pi, etc , these instructions will still work except that you will be attaching your own controller to the LCA chip and you will need to write a little code to control it. Simply wire pin 4 and pin 6 of the LCA to the two foil fingers of the K'nex motor. If you are using another controller arduino, raspberry pi, etc instead of a Circuit Playground, attach a digital output pin from your controller through a 1K ohm resistor to pin 1 of the LCA Attach pin 2 of the LCA to the ground pin on your controller.
I can't identify the particular chip can you help me Question 3 years ago. Can anyone help me with mine? I can't figure out if I can use this portable DVD player,i have the chip name and data sheet. But I'm new to this and don't know all the shorthand, The chip is a mediatek mtkqe. I1m working on this media player that has not dvd drive, just a memory card slot and two 3,5mm jack AV input, but it cant recognise any signal.
Then I tried that you did, i took apart and found the IR3Y29B processor, and the wire for it, but the wire cant recognise any signal too. Could soeone help me out what could be the problem? Reply 4 years ago. Thanks for sharing. I can only find the data sheet with feature descriptions that clearly indicated that there is video input but I could not find any literature on the schematic.
Any idea on how to identify the pins or the schematic would be much appreciated. I'm working on a portable dvd player myself, however, I'm stuck. It looks like the connections go straight from the mainchip right into the lcd. Oh, and marketroid bait like special-offers-for-a-limited-time instead of genuine good-will long-time policies do nothing but offend me even more instead of redeeming some respect.
Then he asks you to go in his van if you tell him your name and other login info. Seriously, they saw the end coming and decided to cash in while they could. They took a good place and ran it into the ground, then shit on it. Still, once it was implemented, if they had only hired more programmers to fix the weird bugs and screwups forum , pop-up ads they claimed they would never host, etc.
Simply because I had found a stable, persistent home for my projects. Instead they doubled the programming staff—to two. At least have the knowledge of site like bugmenot that was posted earlier if you want to avoid registering. Christ, ignorance is more annoying that add filled sites. Paying is optional. And there were other plans to limit content access.

Seriously, though, that was a nice gesture. Can someone explain to me how this makes Instructables easier to use? What a bunch of retard comments! The epub link is at the top and mobi reads it fine. Caleb Kraft — Thx! Hackaday and Instructables. See next steps for some pictures of the actual build. Attachments hemnes. I used a regular old jig saw to cut the wood into pieces. In it, you will find three versions: 1. The initial design, which I started out to build.
The thing I actually built. The improved design, with a wider plank width for the flat elements. Attachments Hemnes mod Publishable. During assembly, I mostly worked on my dining table - the perfect size for this kind of project. And once more, just because I'm so happy with it: an image of the final result! Did you make this project? Share it with us!
