For a guide on how to do this, please see this log. The latest keyscan Arduino code can be found in the project's Github repository here. Even though each vintage toy piano may have a slightly different construction for it's keyboard mechanism,...
Simply cut button wire/trace and solder ATtiny13, it would receive button press and trigger toy. Some toys triggered by LOW level, some by HIGH (A and B), check your wiring and comment/uncomment define accordingly. The same applies to LEDs. My Dracula...
Wheel orientation is critical! The only parts from the toy you need to keep are the wheels and the screws they're mounted with. Note that the toy has many other useful parts, including a motor control IC, 3.2V lithium cell with charging circuitry and...
1) Up down mechanism is quite easy using a old toy car wheel. 2) Just Hot glue the old toy car wheel to the servo arm away from the center. This acts to lift the arrangement smoothly. 3) Fix the arrangement to the other side of the slide.
For a guide on how to do this, please see this log. Feel free to ignore the last part about connecting the circuit to the BeagleBone Black - this will be covered in a later instruction.
Solder the switch contacts to I/O 8 and gnd. Solder wire to the speaker and attach the other end to the amplified output of the shield. Also solder the jumper spots on the shield to increase the amplifier gain to maximum. This will...
Once the toy is open, you can pull all the guts out from the plastic casing. So all you should have left is just the bubble module and some wires and tubes dangling out of it!
How to build a scraptrack:Step1 find an RC toy you like, but want to make autonomous.Step2 buy an Arduino (I like the Uno dev board)Step3 buy a motor sheild, or build your own.Step4 wiring!Step5 programmingStep6 sensors!Step7 more programmingStep8 frantic...
Place all your components inside the enclosure of your choice. I found the dog chew-toy a perfect fit as they are designed to take more abuse than any other enclosure I can think of.Add padding/packing around the electronics to protect them as needed.Here...
affix the LED to the muzzle of the toy cap gun. wire the LEDs back into the handle area. bore out the handle, and insert the microcontroler, battery, LED pins, and a trigger.cover up the bore hole where your electronics are stashed. trigger the muzzle...
Assemble a robot. It can be anything with wheels that moves: either you build one from scratch, you convert a toy or get a dedicated platform. Ideally it should be able to keep pace with a running human.Personally I go for 4WD rovers, where each wheel...
This is definitely not a model to try if you are a beginner. Being a low winger and a speed plane it might require very quick reflexes in tight spaces and a lot of experience in this domain. Depending on the configuration, I expect that it can reach...
Some essentials are Photo Mount / Display Mount, Cardboard 9single or double corrugated is fine), Sticky Tape, Hot Melt Glue, Scalpel and Ruler. As mentioned, 3D printing is not essential, but you can get into that later, if you have / access...
