Real Hardware, Main Voice Oscillator and Keyboard
Log from Synthe555er
Finally some progress on this project. After all these simulations it is time for some real (working) hardware. Enjoy this highly technical drawing: This board contains all circuitry which is shown in the main voice oscillator testbench (Oscillator,...

Hardware
Log from Power Monitoring
The module consists of 3 main components: PZEM-004T v3.0 – an upgraded version of energy meterWT32-ETH01 – well knows ESP32 but with wired ethernet connectionOLED display (SSD1308 128x64) A few words about the component choice. WT32-ETH01 was chosen...

Log 2: Battery, Regulator, and Solar Energy Harvesting
Log from Electronics Power and Energy Modeling Tool
SummaryThese modeling tools follow the block diagram shown below. All of the threads combine to form the "system." This is powered from battery through a regulator. Future features may be added to support more complicated topologies, but this covers...

First Update - Basic Info - 02/28/2022
Log from Alice (3d Printer)
Today is not the first day I have worked on this project, just my first log. This will be stream of consciousness and as-best-I-remember-it. I will forget things. I will get minor details wrong.I am approaching this project slowly. I have a lot...

First integrated test
Log from Automated storage and retrieval system
We did a lot of CAD design and before we continued tuning the design we wanted to do a basic test of the system. We build a rig with some 3D printed parts, empty filament boxes and metal pipes. A temporary rack was made with some wood and 3D printed...

The Descrewer Design
Log from The Disassembler by team Table Flip
It’s getting harder (and more expensive) to get components for our projects. Three of us (@dragomir, @jmakivic, and @LookHere) came together to see what we could do to extract useful parts from other devices. Originally we came together to...

Hardware Design
Log from DIY Retro Audio Player
From the beginning I knew that I wanted to go with a retro design. I had a few details in mind that I wanted to incorporate: The interface would be as simplistic as possible, with the classic buttons you can find on any cassette recorder. These recorders...

New prototype : Joytojoy v2
Log from Joytojoy
To test our solution with a wider panel of users and makers, we have to quickly facilitate its fabrication. The longest and most error-prone process was electronic assembly, wire and components soldering. We design a PCB to reduce assembly...

[M] Left Arm Section
Log from Tetent TimerSpy [gd0136]
I found out that this project just released the CAD files, and one of the things I was interested in was the arm scan. A while ago, I skimmed through GrabCAD and yeggi for an arm model (because I can't "section view" my arm IRL) and found nothing. ...

[T] Use CM4 for its MIPI DSI feature?
Log from Tetent TimerSpy [gd0136]
[00:45] While I've spent most of today computing my options for the #T^2 TyMist [gd0138], I started to have concern for the methods of controlling the OLED for this project too. I found these relevant projects: https://hackaday.io/project/364-mipi-dsi-display-shieldhdmi-adapterhttps://github.com/ylj2000/HDMI_To_MIPIhttps://github.com/peng-zhihui/HDMI-PI...

Getting a Second Skin
Log from OSI Challenger 4P Reproduction
Every Tuesday night my local makerspace (Kwartzlab) opens up to the public. People can get tours, seek member's advice, or apply for membership. Members come on Tuesdays to catch up with other members or work on their latest projects. I really missed...

1.- Error de temperatura
Log from Reparación de un amplificador de audio
El problema de temperatura fue el primero en afrontarse, aparentemente el amplificador entraba en protección de manera innecesaria. Esto llevó mi atención al funcionamiento del circuito de detección de temperatura, el cual se...

1.- Fundamento teórico
Log from Protector de altavoces
Los altavoces generan las ondas de presión que interpretamos como sonido comprimiendo y expandiendo un volumen de aire de acuerdo a una señal eléctrica de entrada. Esto se consigue mediante una bobina que desplaza un área (o...

Modeling the Map
Log from The Interactive Air Quality Map
There are no two identical places on earth, every area on the map is unique, this is an important point to keep in mind throughout this build, seen as the process used to build up one area on the map will need to be repeated to make up the rest of the...

New prototype
Log from Wigglegram esp32-cam
Rework The first thing I realized from the first success was that my method of "cut some slots in a cardboard box, shove the boards in them, and hold a bunch of wires to try to get a photo" was not only not sustainable but produced terrible results....
