Remember the last logs : the goal is to use as few transistors as possible to send a string of consecutive non-overlapping pulses to several pass-gates. Here the design uses NPN as primary type but it will be reversed later because PNP are the majority...
While we were trying to figure out how to display it on a 4x8x32 LED matrix we decided to take a little break and try and wire the speaker to the Arduino board using a resistance. The only issue we had with this was the quality of our speaker. We ordered...
I started wiring up the Memory sub-system board and realized quickly that I needed the display board to show the state of the various registers. I first had to create a backplane to connect the boards into. The backplane carries all the signals...
In order to decode the 23 bytes of payload that the sensor is sending we need to implement a decoder, in this case we need to create one custom. Once you select to create a custom decoder you just simply copy and paste the next code which is written...
1 Intro The Enecsys Gateway is a Zigbee gateway allowing communications between the Enecsys microinverters and their monitoring backend. The Enecsys company is unfortunately defunct since 2015 and their DNS domains have been taken over by a UK enecsys...
These are parts of AIME's operating system that I am beginning to shoe-horn into a Raspberry Pi or more probably a few Zero's networked together inside a smaller and less sophisticated quadruped. AIME was 3.2GHz dual-core intel powered and a lot more...
First of all, to obtain weekly comics release lists from the ShortBoxed comics API, I developed a web application in PHP running on Raspberry Pi. Then, I used an Arduino Nano 33 IoT to get comics release lists transferred by the PHP web application and...
Saturday, 15:08, 26/11/2022 - This is a bad idea. "Why a human-sized mech, and not a exoskeleton?" Well... Sigh... Because the biggest limiting factor of any exoskeleton/power-armor/exosuit is the squishy meaty "pilot" inside of it. The machine...
So even after all of our effort we couldn't manage to make it work for our big LED matrix, so we went back to the simple 8x8 one. We then tried to link the speaker to the Arduino board with the LED matrix and the accelerometer, but we ran into another...
An Integer Version of the DemodulatorAs the code will be ported to a lowly Arduino using C code, I first looked at if I could use 16 bit signed integers. The answer is strictly yes. Strictly in that the 32 bit result of a 16 bit multiplication is not...
So I've recently got a fully electrically and mechanically complete CAD model of Tetrinsic and was, once again, doing some research for Tetent, mainly because I don't like how this featureless flat face looks: It turns out that the eteeController...
THE DAY AFTER......As we walk casually to the workshop, and discuss the various quad copter projects, and my old Traxxas RC truck which I have up the bench to repair it's glow engine and trying to find other radioactive sources to test geiger counters...
