I grew up in the age of the Soundblaster soundcard, the reputable brand by Creative which lead the charge in MS-DOS supported audio. In my eyes the fabled Soundblaster Awe 32 with soundfonts was the creme de la creme of soundcards, with its own RAM for the benefit of playing the most deluxe of MIDI sound files for your games and audiophile excitement, back in the day of the ISA standard for add-on boards for your computer system, a standard that lasted for a long while until PCI came along.  ...
I haven't thrown it away. I still have the Playstation 4, if you remember the last time we looked at How not to repair a Playstation 4 - The Risks of Second Hand Electronics , my intention was to look again at the vias and pathways on the board and see if I could resolder the connections from the HDMI port to where they were supposed to go.   However, unlike many of you who are very capable at soldering (according to What (metric) size have you managed to hand-solder ? ) I am... not, well ...
I saw that this is going on through tomorrow in case anyone is interested.  I think I'll try to catch a couple of sessions tomorrow.   https://makerfaire.com/virtually-maker-faire-2020/schedule/     ...
It feels a bit strange to be working on my projects in the midst of this Covid-19 crisis but since the advice is social distancing - I guess it is an appropriate activity.  Hopefully isolation will slow the rate at which the virus is spreading so that a mitigation strategy can be implemented.   I've been working on my low power (5.5W) laser setup that I've described in previous blogs.  I've recently been doing some lightweight cutting of 2.5mm thick craft wood.  I've been us ...
I'm starting to get more experience with my laser and I'm trying to do some photo engraving on craft wood.  It's taking a lot of iterations to figure out the correct settings for transit speed and power for different materials and my workroom is starting to smell like a fireplace !   I had planned to do some active ventilation and/or air filtering when I started using the laser to cut wood as that generates a lot of smoke but I'm discovering that engraving is also problematic even ...

Laser Operating Sign

Posted by ralphjy Top Member Jan 18, 2020
I'm continuing to work on enhancing my laser setup.  One item on the list is a warning indicator that the laser is operating and that it is not safe to enter the room.  I plan to put it outside the door to my computer room (the access to the workroom with the laser is through the computer room), so one requirement is that the indicator should be remotely controlled via WiFi or Bluetooth.  I received an Adafruit 8266 Huzzah board in the latest Element14 goodie bag and that seemed l ...

Trying out my laser

Posted by ralphjy Top Member Jan 7, 2020
Santa brought me a laser for Christmas and I finally picked up the last piece of required safety equipment - a CO2 fire extinguisher.  So, I finally get to give it a try .   I have a SainSmart Genmitsu 3018 Pro CNC router that has provisions to swap the spindle for a laser module.  I am using a SainSmart 445nm 5.5W laser kit.  There are less expensive modules available, but I've found that it is difficult to get a good set of specifications on these units and decided it wa ...

Laser for Christmas

Posted by ralphjy Top Member Dec 26, 2019
Santa brought me a low power laser module for Christmas .  It is a 5.5W 445nm blue laser kit that is an accessory for my Genmitsu 3018 Pro CNC router  https://www.amazon.com/gp/product/B07RV8TG18/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 .   I'm going to use it to do engraving and lightweight cutting.   I'm going to install LaserGRBL and play around with that before I actually try running the laser.  I'll post about my experiences next year as I get ...
This blog is written to help me remember this trick.  I'm sure its actually a common approach, but it just wasn't an approach I've bumped into. Original issue:  PS4 HDMI Port Failure  The HDMI port of my son's 5 year old PS4 had a couple of bent pins that would push back into the unit.  In turn, it had no display.  I found a replacement port for just 5 bucks, so I decided to give it a try versus scraping the unit.   Removal of the Port: I removed the port by snippi ...
I have enough game consoles in the house, they're not all current generation. I have a Wii, Wii-U, XBox 360, Nintendo (3)DS, GBA, Gameboy, SteamLink to my gaming PC, and access to a Playstation 3. A friend of mine offered me a copy of Destiny since I've been playing Destiny 2 on the PC and I haven't finished the first.   The problem? It's a console exclusive, so I thought to myself "What if I managed to get a Playstation 4? I can play Destiny 1 free online with it and... maybe if it's a bi ...

Forgotten treasure

Posted by gecoz Feb 21, 2019
I can still remember when, more than 4 decades ago, I was used to go and visit my grandmother Vincenza at her place for every holiday. It was never a long stay, just a day trip, as she lived in Nettuno, near Anzio (famous for the landing of the Allied forces during the second World War), about an hour away from Rome, where I was born. We would arrive usually mid morning.   There were a few hunches that would make you immediately realise that was my grandma's home: the first was the lovely s ...

Retro Gaming Round Up!

Posted by plowe element14 Team Mar 6, 2017
Gaming continues to be a massive market with global appeal. While consoles like the Xbox One and Playstation 4 battle it out for supremacy, there is a movement that has been building for a while now- a movement that is seeing some of the old school classics make a return to our gaming screens in a big way.   Now, I'm a nostalgic kinda guy and think that people connect best with the things they have fond memories of, which is why Retro Gaming is back with a bang. A serious bang.   The ...
This program simulates the operation of a strip of interactive lights placed along a stair. The lights are controlled by two pairs of photocells at the ends of the stair.  The lights turn on and off with a sequence depending on the direction you walk. A count instruction prevents the lights from turning off when the stair is occupied. A PLC is a bit expensive for a project like this. However there is an application which converts ladder logic into microcontrollers code. https://drive.goo ...
For those outside the UK, Argos is an unusual kind of store. It's a catalogue shop, so it's products are essentially mail order. Except Argos has a massive chain of high street stores, so it's mail order goods where you actually go into a store to buy the stuff. Just like non-mail order goods...   Yeah, I know it doesn't make any sense, but the company's been going for a long time, and over here you just accept the non-sequitur of its existence, and move on.   Argos, Winter, 1985. It ...
