Auto-pulse, auto-brightness
Log from Yapolamp
Last time we noted that the 2.2mH inductor was going to need long pulse-discharge periods to drive the planned 6x LEDs for the next version of #Yapolamp . I thought I would go for a 1mH inductor but plumped for a 680uH one instead. I ordered it...

ESP8285 GPIO
Log from One Tube Nixie Clock
Theoretically the ESP8285 has 17 GPIO pins and one ADC pin. The bad news is that many of these are already assigned to specific functions. Some of them are still usable, with restrictions, some aren't usable at all. First here are GPIO states for various...

Version 1, kinda.
Log from [mUPS] Minimal UPS for Raspberry Pi
I'm calling it version 1 with the intention of revisiting it to address some lose ends and make some improvements. Version 2 will come when I need a longer hold-up, rather than the (almost) immediate shutdown. You can find my excuses elsewhere as to...

Progress and some actual testing
Log from Lithium-Ion Battery Monitor Library for Arduino
This project has moved pretty fast overall, not sure how long I expected this project to take. Either way, I have been waiting on some OLED I2C displays to actually test this library properly and they finally arrived (I plugging into the arduino...

September 2019 Update
Log from mjbots quad
I've made a lot of progress in the last year, but of course still have a lot to do! This update video has a quick tour. And now for some details, eventually I guess I should split these up into their own separate hackaday.io projects... Moteus...

Much Ado About Batteries
Log from Open Autonomous Domestic Robots
This post is going to be less of a project update, and more of a stream of consciousness monologue about one of the aspects of OpenADR that’s given me a lot of trouble. Power electronics isn’t my strong suit and the power requirements for the robot are...

Broken but not bowed
Log from Cardware
OK so I've had a good cuss at those rotten processors. Other than commenting that 'Well, I think MOST of them worked when we packed them...' just isnt good enough when money changes hands over it I'm done with them. Maybe I'll come back to them later...

Laundry Tracker
Log from Sci-fi grade Home Automation
After I accidentally left my laundry to rot in the washing machine one too many times, I decided to permanently fix the problem with a Spark Core. I rigged it to cheap door sensors (http://www.amazon.com/Wireless-Doors-Windows-Security-System/dp/B00CDCIP00)...

A quick fun test with better filters..
Log from ramanPi - Raman Spectrometer
Ok, so I totally re-wrote the code for the CCD driving.. I actually totally removed the PWM driver for the ICG line and replaced it with a sort of state machine driven by the Shift Gate... So, now the firmware tracks the pixel position and...

Creating a Custom Weight Scale
Log from analog.io - A full stack IoT platform
I published a summary of my previous scale project. In this project I hacked a postal scale that was purchased off of Amazon. This has been working really well, really the only complaint is that the scale area is smaller than the Hive base so things...

Progress + Testing
Log from Motion Sensor Audio Trigger
Last week, I continued work on the project during a weekend that was extended due to snow. I started off by running the Blink sketch on the Feather board. The board proved to be similar enough to the Adafruit Trinket that I have some experience with,...

log 4 - 2d 2 servo arm joystick control of x,y
Log from Quadruped learning project
Today I made to working order (very simple, no stability engineering) a joystick controlled x,y directed foot for a 2d 2 servo leg. (as pictured previously). I will post an 8 minute video below the code. I do have some trouble. If I move the foot outside...

RF capability actual first success
Log from Quadruped learning project
This log is to describe my first experiment related RF capability success. I have managed to mostly replicate the success from my previous 3 joystick axis, 3 servo, xyz coordinate kinematics engine experiment,,, onto a wireless controller to servo driver...

rf + servo shield intro,, more log later
Log from Quadruped learning project
I will have to make a "real" log to discuss my activity, but this will be a short intro because I'm not prepared to make a good log entry. I've switched to working on my quadruped model instead of the cardboard leg,, but ALSO, am on a work trip so don't...

Free-running!
Log from Big Daddy 68k
This project started with me seeing an MC 68000 on a breadboard blinking an LED. It seems this is a rite of passage for 68k builds. Although a little bit of a challenge at the time, it's a great way of getting to know your way around the physical package...
