This took about 1.5 hours today to build. I suck at soldering or it probably would have been faster. For influxdb and Grafana, I simply followed the instructions on the respective websites. I'm thinking I might add some calibration code to the ESP code...
Short demo video: ---------- more ---------- For this I took a single TEC2-25408 Peltier element, which sits on a Thermalright Peerless Assassin 120 CPU air cooler. On the cold side of the Peltier sits a 100 x 100 x 2mm copper plate into which I drilled...
This coffee machine is by now up and running for about 1.5 years. I started documenting and open sourcing everything offline; this month's Hackaday Prize was the motive to speed things up a bit and put it online. Project logs will follow...In the project...
Compared to the original #192:LED design. Nearly everything did changesmaller: 15.8mm x 14.6mmNo complicated Multiplexing anymore! LEDs are WS2812 style ones in a metric 1515 packagesmarter: MCU is a SAMD21USB: quite more convienat and easier to...
Requirements To start and designing such product is to understand how Peercoin algorithm work : everything is well explained here https://university.peercoin.net and here https://www.peercoin.net/wallet to download wallet on your machine...
Aims:I don't want to buy an external phono stage, and everything is set up for one inside my amp, so lets build one. First to work out the spec.1. Must work with MM (Moving Magnet) cartridge turntables. These require the least amplification, so are easier...
I am going to be 3D printing a Qi Charging case for my phone. This is a pretty complicated project for something that involves 1 3D printed part, one component module, some wire, and some washers. 3D printing off of the bed using carefully designed support...
This is an ongoing longterm project to create dual channel precision bench power supply 2x50W with ultra low output ripple, fully programmable and adjustable from PC. Output channels are independent or connected in series or parallel. It will contain...
The TinTTY hardware setup is simple: Arduino UnoTFT screen (1in x 1in ILI9163C), connected via SPIUSB Host Shield, connected via SPIcheap mini 2.4GHz wireless USB keyboard The input device, by its nature, cannot be too miniature, otherwise it becomes...
From the picture it looks almost done, but far from it! This was just a layout test. I need to redraw everything, make it smaller and find out the arrangement of the LEDs first. Some things have to be fixed in software, as the original layout for...
There are four main components:1. The control board (that I'm making myself)2. A Tamiya tank chassis and gearbox3. A raspberry Pi with web server and fcgi API1. The control boardGoing on Version 7 (Minified3).MCU used is AT32UC3L0.Using separate battery...
The idea is quite simple: Stick some resistive wire under the build plate and tap into the 19V power supply of the Cetus to heat it up. I started by drawing some guide lines on the under side of the Cetus' build plate: I then covered everything except...
I wanted to make a portable outdoor sound system that actually sounded good, and could be heard.I didn’t think this was much of a hack, I am just connecting off the shelf stuff, but a friend said I should send it to hack-a-day. I go camping(if you can...
I've been a fan of Apple's hardware since the early 2000's when they first introduced OS X. I had enough of Windows, its inferior architecture, and poor stability. OS X was stable, fast, and under the hood was Unix. The PowerBooks were...
This clock will tell you everything you need while you’re in bed. It tells you the time and date of course, but it can also tell you the temperature outside the bed, or the weather forecast. During the day it can function as an atheistic piece, showing...
