The lion kingdom suspects most of the EOS RP's in the world are dead or going to die after short lifespans. The environmental shielding isn't there. The lion kingdom's EOS RP died after being splashed with a small amount of water. It...
During a mission at an industrial agri-food customer, I found a barrel of raspberry pulp at the company's waste disposal site.Guaranteed without petroleum residues, I immediately thought of having a barbecue. Here are the design steps in pictures.Such...
So, to date, this project includes the following high tech concepts: Green construction using locally sourced bamboo - it grows everywhere in D.C.Composite construction of mast points (fiberglass and epoxy resin on the bamboo poles), creating a mast...
This project is very much in an alpha stage. It's the first time I've designed my own circuit using IC's (I used to do chip level repairs, not creating my own)The schematic looks absolutely horrible, I know. I should really have broken it out into subnets...
There's a few reasons I'm working on this besides just creating yet another little ARM Cortex-M dev board:I've had plans in the works for a beefier Cortex-M0+ board for a while now, and this is, in a way, a first step towards thatI really like NXP's...
HardwareThe sole signal needed by star-cycle is a pulse on one of the Raspi's IO-ports on every revolution of the pedal levers. My exercise bike has a tachometer generator, consisting of one reed-switch that is closed once per revolution. Normally, this...
Late last year, I found Mohit Bhoite's instagram. He had posted a picture and video of an HP 5082-7415 that he was going to use in a project. This prompted my unnecessarily large order of all sorts of vintage LED displays including an HDSP-2111,...
When the ESP8266 came onto the 2014 IOT scene by storm in the form of a tiny 8-pin system-on-chip repleat with on-board WIFI, I was an eager early adopter. I bought a fistful of dirt-cheap ESP-01's with great intentions to build a network...
Why mighty ATtiny? It's dirt cheapIt's quite capableIt's just enoughWhen it's not, it's challanging ;) Why ATtiny Flasher? Code, build, flash, test, code again, without interuption. Just like normal Arduino boardDebug using Serial. Just like normal Arduino...
The RepRapXY is a coreXY design RepRap based on Zelogik's machined aluminum coreXY this variant was developed by Jand and sdavi. Jand created the 3D printable version of Zelogik's and sdavi added the modification of horizontal Zelogik's RepRap.org thread...
The LED's in this project are SunLED's, which are bi-directional LED's. There are three types of LED's used, blue-red, green-red, and green amber. I got them from digikey, and they're about $0.20 each in quantity. You could in theory...
Well here's the project, finally. After so many months I've finally uploaded it!I got asked by a teacher at the Erasmus High School in Brussels to make a Game Boy XXL for him too. I've already put some time into the new one but since I've got a few other...
Specifications Utilizes an ESP32 as the microcontrollerCode will be written in C using Espressif's ESP-IDFSensor transmits data over ESP-Mesh networkBoard will be programmable with a daughter board and micro USB cableSoil moisture will be calculated...
The whole project started after seeing a commercial for the toy on a Jaboody Dub's twitch stream. The meme potential was just off the charts. Hardware wise, it's an ESP32 running Arduino which plays audio from a SD card via an i2s dac+amp. Also there's...
This is an art installation project for my non-genetic brother - it is an old Mexican cantina sign he found at a flea market (Elephant's trunk in CT) which I am tarting up to have 36 high power RGB LED's - that means it's going to need 8...
