With the median filter/edge detection from the previous log the following two images can be generated from the hackaday logo...median edge (=cleanup + edge detection)median (=cleanup of jpg artifacts)For the edge picture, it is possible to implement...
The HP 8647A is an excellent signal generator with a lousy power supply. Here is how to use an Artesyn LPT-103-M and an XP-Power EML30US36 to replace the dead original. CAREFULLY use a jeweler's screwdriver & magnifying glass to set the XP-Power to 38...
As I've mentioned in the project description, I started the project with a pen form factor controller in mind. So when I started to build the perfboard prototype, I decided to construct the prototype with exactly the same components as I would in a compact...
I know, I know - It's been a long time seince I've written (and done) anything on this project.A lot have happened although not that much on the project specifically. I got married, I've completed my laser cutter (at least to a stage where it can burn...
I recently got a message from a 'community manager' at hackaday.io requesting that I post more pictures of bright. I threw together a rough prototype on a breadboard with an arduino pro mini, but ultimately didn't want to post pictures of it. I wanted...
Printze was a months-long project... Where're all my logs?Off the tlp of my head:Goopy-vias from blown caps was an early thing, fixed...Blown transistors, replaced...Once functioning, a little alcohol revived 20+year-old ink heads.Injected ink from a...
Copy from old blogWire Works & Free-Wire Circuit Basics :: BarnBrewMaker (webnode.page) So this is technically my first blog that focuses on my interests. And here I am going to introduce my Automation, Wire Works/Toys & Free-Wire...
Today ICStation Team introduce you the amazing calendar. You may say there is nothing special from the front of the picture.But this calendar can display apart from year, month, day, week, hour, minute, second and also the real temperature.And I still...
The problem with ideas : we know when they start but not when (or if) they end !Some famous historical computers have a "dead start panel", a plate covered with switches that encode the first instructions to execute when the power is turned on.For the...
Well this is sad. I really didnt want to post this but the last few weeks I've been really struggling and contemplating doing this... I have to admit defeat. This version of the project is now dead. Which is a painful shame given all the hard work...
Linear motion is a mode of movement where all three degrees of rotation are fixed and two degrees of motion are fixed so that an object can only move along one axis. This is how the bold on a dead bolt moves, how a drawer slide moves, and how a...
The Situation:I have a PCB mill. It is pretty antiquated (it has a DB-25 RS-232 port!) but otherwise perfectly sufficient for my needs. Unfortunately after working with LPKF support to sort out a DB-25 to DB-9 adapter and hooking up a USB/RS-232 adapter,...
This weekend did not go as planned, there were a bunch of setbacks... First of all, I'm still waiting on the Z-axis stepper motor, but that should goefully arrive this week. What should have just a quick test of the firmware and the X- and Y-axis turned...
