Mike's Software is Broke...Again!
Log from Bobble-Bot
The only excuse I have left Why test when James breaks everything anyway? Developing software for a complex embedded system is hard. Tracking down a single bug in such a system can often take hours. Even worse, "fixing" a bug in one of these systems...

Log from Parallax Update Hack Chat
Ken Gracey (Parallax)12:55 PM@Chip Gracey - marketing question! What's the ideal application? Do you foresee people using it as general-purpose or for a specific app? Maybe some of the forum members can share ideas. Frank Buss12:56 PMI think this interactive...

Modules under the hood
Log from PiXPi dslr camera controller
Hello, today i wanted share some detailed overview of modules, how they built and more importantly how they communicate with main controller, it's significant as standarized communication interface is something which make possible to easily extend...

Log from Linux in the Machine Shop Hack Chat
Andy Pugh1:01 PMI suspect that the inverted board on the right could be pulled off, and step/dir pulses fed into the headers. Axel1:01 PMSounds like a plan! Axel1:01 PMjust some tracing. What would the controls of a stepper driver be? Chris Radek1:01...

Motion Primitives
Log from CAN Controlled Dual Closed-Loop Motor Controller
OverviewIn robotics, online motion planning can be computationally intensive and/or add significant network load. To avoid this, motion primitives are sometimes used. The concept is that the higher level controller can command pre-determined trajectories...

Some of the basic ideas that seem to be working
Log from Minamil 2dc: a minimal CNC mill
(update: add note to Structure:Alignment)Here's an attempt to describe some of what makes this extremely low cost sub-mini CNC mill work. Hopefully having it somewhere to refer to will simplify writing more about how to make one for yourself! Axes Looking...

Core Console
Log from Think-a-Tron 2020
The heart of Think-a-Tron 2020 consists of three main parts: the camera QR code reader section, the display, and the question (?) console with speaker. The ESP32-CAM is mounted in a rectangular box forming the main part of the core section. You can see...

LAUNCH! Final Proof Test: Building a Test Sound Player in C
Log from HBSound
Introduction: So over the last week or so, I have been building on trying to test out HBSound at speed in a way that verifies all of the different subsystems of the module. In order to do that I had to make some slight modifications...

Project Log 27: 34000 liters per minute it is.
Log from DIY Mech/Exoskeleton suit.
It is Wednesday my dudes, 15:56, 22/02/2023 Well, let's see if I can get this right this time. I will first try to make that dang equation work, and then I will try to see articles using actual heavy duty McKibben muscles and guess the dimensions...

Project Log 55: DIY Hydrogen Fuel Cell.
Log from DIY Mech/Exoskeleton suit.
Sunday, 18/06/2023, 18:25 Soooo... I don't even know why I'm writting this project log, I really don't think that I will have the money, nor the mental fortitude and determination to go through with this project, but for some reason, I keep going forward....

Explanation of PoE and Development of Modules
Log from What is PoE? My tough PoE development process
POE(Power Over Ethernet) It refers to power transmission technology itself, and its components are divided into PSE and PD.It is a technology that can transmit power and data to devices over Ethernet using Cat 5 twisted-pair cables.It can operate without...

Initializing ROM during build-time from files
Log from From bit-slice to Basic (and symbolic tracing)
(for related subject, run-time initialization of ROMs/RAMs, see here) FPGA-based designs often have various read-only stores. Their content can be defined in different ways: Inline in the source code (appropriate for smaller ROMs)Using vendor-specific...

feature creep vol. {n+=1}: doors
Log from Minamil 3dp: another minimal CNC mill
Another log mostly about already-dead stuff that I took pictures of before breaking it down to make it different again. I tried to make this vulnerable corner at least not super fragile. It turned out to be super not fragile. It will take a much harder...

Launcher
Log from Apollo Saturn V and LUT
I am working on the Saturn V and realized it's looking a lot like fall out there so I wanted to complete the wooden box structure of the launcher while the temperature in the garage is perfect for wood working. I had plenty of scrap wood from other projects....

Can your phone double up as your name badge ?
Log from Kite : Open Hardware Android Smartphone
After we built Poorna, our base model, we had a bit of a problem. We had engineered a lot of flexibility into our design. Folks asked us, “what can you do with this?”. My typical response, invariably, would be “a lot – anything,...
