I've always loved the sounds of the TI SP0256 allaphone chip and was hoping to find something using it for this project. That's chip is what gave the speak-and-spell its robot voice. I picked up a "VTECH Talking LITTLE SMART alphabet DESK" at a garage...
I designed the first pass of a toy pushbroom image sensor. This should get me started, anyway. The sensor is a TSL3301CL, with 100x1 pixels, 77x85 microns each (centered on 85 micron centers). These are big pixels, so noise will be...
A Toy PIMD I would describe this PIMD as a "toy". Why? Because it is necessary to detect the target signal immediately after the coil signal has decayed below the target signal, and before the target signal has decayed below the 40 mV threshold. In the...
One of the ways forward on this project is using diode sampling gates. Schottky diodes that can switch well into the tens of GHz are readily available, so it's just a matter of connecting them to the right stuff :-) I started out with a toy version -...

The first part of the drone I took apart was the camera. It is a complete linux machine based on the HiSilicon HI3518 ARM SOC that usually finds a home in Web Cams along with a USB-connected WiFi module and a 4-wire connection to the Drone itself. It...
The computing unit is fine but I have not even covered the memory aspects.I'll leave the instruction memory for later, since I'll need quite a bit of it. I'm focusing on Data RAM (less memory needed), and there are 2 memory ports.I decided to use a unified...
By whygee on Monday 19 January 2009, 00:34 - FPGA As you may know, YASEP16 will probably be used in my girlfriend's "pet projet" Ours Agile. This involves lots of real-time computations, countless sensors and more than 30 actuators... Sure, YASEP...
I've been playing a lot with my new "toy" and it performs better than I expected. Here is a little comparison of the kind of details I can obtain with it:Left is from the photo I took with my Galaxy S10, right from one took with my document...
An improvement has been on the design board to increase the size of the legs and use the 1980 ATAT toy as the body, add the servo legs, and get the original toy to walk. I added a servo to the knee joint in my first print/test. Now 3 servos...
The toy is essentially done, and working properly. I encased it into a baltic birch enclosure, with lots of hot glue and CA glue. The openings are for the buzzer and the micro-USB charger. I was surprised that it was nearly too large to fit inside the...
(Original post date: 03/04/16)In order to undertake this project I had to completely take-apart the toy piano, unfortunately slightly damaging it in the process due to the way it was originally connected together. As all the electronics for the project...
Because my hobby budget is close to zero I often search thrift stores and fleamarkets for electronic junk i can salvage for parts. I recently found a toy soccer scoreboard / game timer that was fully functional for only 1 euro.After taking it apart,...

Here are the main mechanical modules that I developed to test my implementation when it is ready. They may look simple, but practically work 🙂Cat Interaction MechanismI took a favorite toy of my cat - a piece of filament for 3D printers.Transportation...
