BB-75 Blasting Machine 320V @ 10Joule (75EBCs) test circuit 800µA; tactile and optical feedback when continuity supply is a 9V battery 89m x 165mm x 30mm; 326g fuse protected test circuit shunted output for EMI protection ABS case with rubber boot...
Going further on the path explained in log 27. What is it ?, I'm exploring the question of addition. The Pisano-Carry state space has the operation "next" and "previous" state but addition is not natural, or more precisely it does not correspond to something...
X-8266 x1X-OLED x118650 battery shield V2 x1Simple 3D printed case X1You can have a look at the pin map.SDA is connected to D1.SCL is connected to D2.This two pins work as the IIC pins.The other pins can be connected to other sensors.The X-8266 can really...
Remapping the KeyboardGiven most of the work is done with the "basic shift logic" how hard could it be?The basic shift logic:Well much harder than expected, here is the schematic:Now many will recognise this as a PLA (Programmable Logic Array).Designing...
The robot is based on Arduino code for Arduino Mega 2560 and it is open-source. Not like CNC machine which has X, Y axis perpendicular aligned and we can find x, y co-ordinate of target by tracking traverse distance of X, Y stepper motor. The wall drawing...
The starting point of this positioning module is that we have three Infrared emitters located on three edges of a rectangle: Our robot is located somewhere in this rectangle: On the top of the robot a IR sensor rotates 360 degrees and detects the angle...
The schema below illustrates the additions to CPU programming model and how they are activated by the upper 4 bits of the instruction register. Some notes:Microcode (or state machine) driving the instruction execution has no knowledge of the registers...
A simple circuit using an Op-Amp and variable resistance. Its a simple amplifier stage.Using a simple line drawing program written in python, draw out the bones of the circuit to scale as it would appear on the circuit board and save the resulting image...
As mentioned in one of earlier logs, I have implemented OLED drawing capability as a simple interpreter for graphics string commands sent over serial link.There are now seven commands available:STOP - stop processing, string terminatorSTRING, x, y, -...
This project calls for a robust and easy to use interpolation function, preferably one that accepts a list of (Xn,Yn) points sorted for ascending value of X. The result should be (Y0) for X < X0, and Ylast for X > Xlast.If anybody has some code lying...
Because the printer should work with different crucible sizes to save time on smaller objects and because the printer has to know the exact limits of the build area it will use a probe to detect the exact position of the crucible center to use it as...
Video GenerationThere are several very good references for understanding how TVs are controlled by a pulse sequence. I particularly liked the Stanford EE281 Handout #7 entitled "TV paint". Also very useful were Software generated video, by Rickard Gunée,...
I struggled a little bit to teach the particle to stop at a collision with a solid object. But now I did it. Above you can see the result. You see 20 particles starting in the area between the tip an the deflectors. The Tip has a Voltage of -100V an...
