Video Tutorial: BME820 Environmental Sensor and MQTT under Micropython
February 20, 2018
This week we’re starting to make our Micropython powered Wemos D1 truly useful with a sensor and data collection. We’ll wire up a BME280 sensor which measures temperature, humidity and air pressure. After we know it works, we’ll use Wifi and MQTT to send the data to a website for viewing.
3D Printing: Knurled brass inserts using a heat gun
August 31, 2017
In my current quest of building the Hypercube Evolution, one of the early and critical steps is putting in the knurled brass inserts into the 3D printed parts. These inserts are the receptacle for screws/bolts that would otherwise chew up the plastic you’ve printed. The standard instructions are to use a soldering iron but I wanted something with a little more accuracy so I used a heat gun. It works well so I thought I’d share a quick tutorial video I made!
Howto: Glass Bed Upgrade for the Monoprice Maker Select v2
June 16, 2017
One of the most commonly recommended upgrades I’ve found (For all printers) is switching to a glass bed (Technically tempered Borosilicate). While it is not a hard nor expensive upgrade, it can be a bit time consuming. Since your bed is very important to the print process, this shouldn’t be something to rush, so I’d recommend at least two hours to complete (not including print time). Please note that the process here should work just fine for the Wanhao Duplicator i3 and similar series printers however you may need to verify what the correct glass size is.
Selecting a 3D Printer
May 31, 2017
The field of Additive Manufacturing at Home, aka 3D Printers isn’t terribly new. However it is still a field in which it’s new to most people. It’s also a field that is very rapidly evolving. Therefore the hardest part for me to write is “which 3d printer to pick” because by the time you likely read this, there will be other new options to consider. So rather than telling you what to select, I’m going to share my thought process and a few things to keep in mind.
Down the 3D printing rabbit hole: a background
May 30, 2017
For those of you who happen to follow me on various social medias may have noticed a ton of Instagram posts as of late regarding 3D Printing. It makes for great writing material. A number of you have strongly requested more details, as it is my style to share my journey, this begins a series on 3D Printing. Let’s start with my background on 3D printing (or lack there of) and what I’m going for.
A $20 tablet/laptop organizer
September 30, 2015
Do you have several laptops? Multiple iPads? Do you find yourself with an annoying stack of laptops sitting on your desk that you need to play Jenga with every time you need to switch machines? If this is the case you might be living in the most egregious world of #FirstWoldProblems -or- you work in technology. I fall into the latter group and wanted a cost-effective and nice way of keeping my laptops & tablets organized, charged, and undamaged. What you see to the right cost me about $20 and an hour of time to make.
A Pinterest success story
August 24, 2015
For those of us who aren’t super crafty types, when one mentions “Pinterest” typically the mind jumps to “Pinterest Fails". You can Google that and find hundreds of websites dedicated to the very topic. However today we’re discussing the opposite, Pinterest success stories, or more specifically one success story. This particular story centers around my niece who had mentioned to me before that she was a fan of Pinterest . However, I had no idea how amazing the results could be until this weekend at her wedding.
Securing your Apple adapters in conference rooms
February 28, 2013
Modern IT is an increasingly Mac-friendly endeavor. One of the major annoyances (in my book) with Macs is the use of adapters and dongles. It isn’t so much that adapters are required, it’s that in shared spaces (such as conference rooms) you need to have them easily accessible AND removable, but not-easily wandered off with. This last requirement is the most troublesome for me because people seem to love to go wandering off with VGA and network adapters from conference rooms. They may have dozens of the damn things back at their desk (because I readily provide them to my users), but they’ll accidentally walk off with another. I found a solution to securing all types of Apple adapters in our conference rooms, and it costs about about $0.10 USD.
Build Complete: My Gaming Rig
March 27, 2012
This is the 3rd post in a series. Check out the first and second entries for information on planning and building your own PC. A few weeks ago I decided it was time to build myself a new desktop, despite not having had one for many years. I set out to build a machine that was reasonably competent at playing games; I also wanted it to be fairly small and quiet. Lastly, I wanted something that would handle future upgrades with a minimal amount of part replacement. This wasn’t going to be a crazy complicated build since I didn’t want to sink a ton of money into it. I ended up with a bit more than I expected…
Building a new Desktop (Gaming) PC: Step 2 – Building
March 22, 2012
At this point, I’m assuming that you’ve got your plan all worked out for the desktop PC you’re going to build (if not, go read my last post). I spent about 2 days in the planning stage; it isn’t hard; it’s just a matter of getting all the research done. After all is settled, it’s time to get to the fun part… buying components and building! I’m not going to talk much about the buying step since that should be fairly self explanatory (and fun! boxes in the mail! it’s like Christmas!). Today’s entry will cover some tips and tricks about the actual assembly of your computer.
Building a new Desktop (Gaming) PC: Step 1 – Planning
March 20, 2012
In all my 20+ years of computer experience, I have never bought a prebuilt desktop PC (for personal use). In the early days, my desktops were hand-me-downs that I upgraded. Later when I had the money, I built or rebuilt machines to fit my needs/wants. About 5 years back or so, I gave up my desktop PC and switched entirely to laptops. My gaming had migrated primarily onto the Xbox, my desktop was outdated and I had brand new laptops (plural) from work. A few weeks ago, I decided that this needed to change. I wanted needed a desktop of my very own again. Of course, the idea of buying something prebuilt didn’t even occur to me.
Recording high quality voice prompts for Asterisk
February 21, 2012
Recently I’ve found myself setting up a new Asterisk box, which is oddly one of my favorite tasks. IP Telephony (or VoIP for the rest of us) is quite fun to play with. Office phones and IVRs are something that everyone uses. It’s really nice to see something you have built used day in and day out without anyone ever noticing it. Asterisk doubles this fun because A) You can make the phone system do whatever you can think of (as long as you can program it) and B) You can build a system that rivals the functionality of the BIG corporate systems… if you know what you’re doing.
