Full Project Log on the RPF My posts copied here. Okay, so I went a bit overboard on this one. (as always) Currently I want to make this for myself and release the design files once done. (If you want me to start a separate thread let me know) I took...
Here are the first three chapters of my arc42-based architecture documentation. Next time we are doing the architecture constrains and maybe the system scope. It is necessary if I want to make it right, but if you are bored, please wait for 2–3...
The title stems from the fact that this revision added wireless functionality. This is the first money spent on this project. A $7 remote control toy car was purchased and torn down for its precious wireless ICs.Basically the parts from the RC car replaced...
Looks like the relay unit sets the brown wire (#2) to high for ~20ms then send a reset sequence and the height value in inches 0 1 0 0 0 0 0 0 0 1 0 1 0 0 0 0 0 0 0 1 0 1 0 0 [BITS FOR HEIGHT]Each bit is ~100us long (9,600 bps? My "logic analyzer" is...
Hello everyone! To begin prototyping my ideas out, will need the following materials: 1- an accelerometer breakout board (which I have already ordered from eBay), 2- a microcontroller (I will be using my brand-new Freescale-based "Teensy LC" for that,...
The project of Simon game was developed as an electronic set for ÚDiF alias Amazing Theatre of Physics. The aim was to create a simple toy to teach basic skills in electronics.The first version (summer 2015) was driven by ATtiny45 or ATtiny85 microcontroller,...
As one dives for wood in dumpsters, one comes across all the flotsam and jetsam of today's throwaway society. But for poor, no-budget me that's a very good thing! The stuff I keep finding is simply amazing. Weirdest thing of all is that I often find...
usually the mechanics of a toy capsule machine is operated by coinonly a round object can push up the "obstacle" that blocks the notchSolutionThis capsule machine is no longer control by coinsif the sensor sense someone toss a ball into the machine,...
I decided that the best way to interact with the servo is to have a dedicated application. I did toy with the Idea of the user changing parameters in the Arduino sketch and re-uploading it to the servo. That's not a real polished product and will deter...
For all of the vintage "toy" computers that I have made reproductions of one thing stands out, they all had excellent manuals. To that end I have created the TMD-1 Quick Start Guide, a small 10 page document that contains: A brief description...
This started with a comment made by Newspaperman5: "Sweet! I would love a smaller and/or more capable version of [TMD-1] as a desk toy!", and it made me realize that I did too! I loved messing around with TMD-1. The tile interface is...
(Original post date - 28/12/15) The first part of this project I have decided to undertake is the development of the key mechanism - allowing the existing toy piano keys to generate note messages in the digital domain. I have decided to start with this...
(Original post date: 06/03/16)Even though I ended up constructing a brand new front panel for the toy piano for this project, the rest of the enclosure of the vintage toy synth will be using the existing piano enclosure. Apart from the front...
In Log #6 I showed how I had gotten the Hoverboard driving, but now I had to consider how I was going to mechanically link it with specific assistive platforms. When I contacted a local Occupational Therapist, she showed me two "Standers" that were used...
I was inspired by pin impression toys (The toy where you put something like your hand on it and the pins make the shape of your hand). If foam could be injected into the shape that the pins make, then parts could be made section-by-section,...
