Creating a wood frame for my projector screen

I have an Infocus IN72 projector that I have been very happy with, in my old apartment I mounted my screen made of Do-Able board to the wall using industrial velcro and was happy. When I left my apartment, the industrial velcro removed the paint and a pretty substantial paper layer from the drywall.

Setting Up Raspberry Pi For the Children

I have not played with linux in probably 10 years, when i did then everything was a hassle. I made a firewall media server device out of a loud and huge dell power edge server. After buying a raspberry pi for my daughter and I to play with I was amazed at how easy it is to install and update linux now, especially on something with common hardware like the pi.

Cloning Raspberry PI SD Cards

After playing with the raspberry pi a bit longer it became clear that I needed some way to make backups of the SD card used for the OS. I quickly remembered that I could easily use Win32DiskImager to write an ISO image and was able to backup my PI easily.

Getting Started with My Printrbot Simple Metal

I got a printrbot simple metal kit on black friday so I have had it a little longer than those who got one for Christmas. It has printed at least 4 hours a day since and I think I have it up and running pretty nicely now, here are my tips for getting great prints quickly.

Just completed a simple touch menu for Raspberry Pi projects using the 3.5” Adafruit PiTFT 480x320 touch screen.

TouchPi with PowerBoost Low Battery Automatic Shutdown

Part of the reason I bought a 3D Printer was to add some polish and portability to Raspberry Pi and Arduino projects, my favorite of those projects has been the 3D Printed Touch Pi battery powered Raspberry Pi case with Adafruit 3.5” PiTFT Touchscreen.

Driving an 8x8 Led Matrix using the Adafruit HT16K33 Led Matrix Driver backpack with Arduino

When Nwazet closed down I bought a number of 8x8 Led Matrices for $1 each. I had these for a while and then bought some Adafruit 16x8 Led Matrix Driver Backpacks - HT16K33 to power the Matrices.

Using Taulman Filaments with Printrbot Simple Metal

After printing a lot of PLA on my Printrbot Simple Metal I started looking around at some of the exotic filaments available. I have a roll of ninjaflex and was interested in some of the filaments from taulman.

Pay for your Printer by Running a Low Cost 3D Hub

After I had my Printrbot Simple Metal for about a month, I found 3D Hubs and I listed my printer at the suggested prices. 3D Hubs suggests a $10 setup fee and $1 per cubic centimeter of filament.

Order a PCB to build your own Zum Scan Shield using OSHPark

Buy a Zum Scan PCB

Don't want to order from 3 places? Buy a Zum Scan PCB and Stepper Driver in the Project Store


One of the more interesting components of open hardware to me has been the theoretical ability to produce low quantity custom hardware based on well tested open source designs at pretty low prices.

Building the Ciclop 3d Scanner Part 1 PCB Assembly and Ordering Parts

On June 4th I ordered PCB’s from OSHPark for a Ciclop 3D Scanner, the OSHPark turnaround was amazing and my PCB’s were manufactured and shipped on the 12th. On June 16th I had three beautiful purple circuit boards in a nice purple envelope.

Building the Ciclop 3d Scanner Part 2 Printing Huge Parts on my Little Printrbot

I have been working on printing a Ciclop 3D Scanner entirely using my Printrbot Simple Metal despite several of the pieces being to large for my bed. Reading forums and searching thingiverse I found most of the files I needed to print the Ciclop on my Simple. I also modified a couple of files so that I could print all the parts on my Printrbot.

Building the Ciclop 3d Scanner Part 3 Laser Cutting and Electronics

One of the final pieces that I had not figured out for my Ciclop Scanner was the 200MM diameter laser cut acrylic turntable disc. There were laser cutting services available from some people I had met at a 3D printing workshop and at local makerspaces but I wanted to try and find a more universal option.

Building the Ciclop 3d Scanner Part 4 Final Assembly

I have been working on my Ciclop 3D scanner for about a month now and the build is almost complete. I had been looking for a complex and complete open source hardware project and the Ciclop has been perfect. Because the BQ kit and components are not available yet in the United States.

Installing the Printrbot Simple Z Axis Upgrade and v2 Extruder

After almost a year with my Printrbot I was excited to see the new Printrbot Simple Z and X axis upgrades they recently made available.

Building a couple Pocket Pigrrl RetroPi 3D Printed Gaming Handhelds

I am building two customized Pocket Pigrrl’s for my daughter and niece. As a kid the NES system was mine, but my younger sister owned the original gameboy which I constantly stole from her on car trips so it seemed right that both our kids have little portable gameboy like devices. I am also hoping that this device will help keep mommy’s phone away from the children.

Installing the Printrbot Simple X axis upgrade

In my ongoing effort to buy every upgrade for the Simple Printrbot offers I bought the new X axis upgrade on Black Friday.

Printing one at a time in Cura with a Printrbot Simple

I love my Printerbot Simple, but I have had a limited amount of success printing plates full of parts since I installed my X axis upgrade. Despite having more bed space I continued to have issues with printing batches. When printing all parts at the same time issues with one print seem to multiply themselves to all the prints sometimes wreaking the entire plate of parts. There are also sometimes imperfections and stringing on parts caused by the extruder traveling between parts.

Dymo LabelWriter 450 Thermal Printer Ubuntu Setup

When I started using Linux printers eluded me a bit, my Canon multifunction printer did not have good linux drivers for quite some time and initially I could not find any software to run my small Brother label printer. Eventually Canon improved their driver and I found a program called blabel for my brother label printer.

Raspberry Pi Surveillance and Timelapse Camera with the RaspiCam

I have wanted to build a motion activated and time lapse capable raspberry pi camera for a while now but never really found a case I like. I found this nice case for a raspberry pi and camera on thingiverse. It was designed for a specific fisheye camera but looking at the model it appeared that one of the cheap Chinese fish eye cell phone lenses I have would fit nicely in the hole.

Using a FlashAir WiFi SD Card with my MAKEiT 3d Printer

I have used OctoPrint to manage prints in the past with my Printrbot. As time went on I found myself using the SD card more often because it was more reliable. When I got my new MAKEiT Pro-M printer I continued to use the SD card because it has a fantastic tune feature that lets me adjust a number of settings on the fly if you are printing from the SD card.

New Project Idea Electronic Fireworks Controller

I decided it might be fun to try and build an electronic fireworks controller for the 4th this year. It seems as though there are a ton of various options out there both DIY and commercial. I think I am going to try and model a .50 Cal ammo can insert for the wire connections, battery and buttons, and hopefully storage for the wires and ignitors.

. . .

Electronic Fireworks Controller Initial Plans

I have ordered up a bunch of parts and have started to map out my design. I think the whole project will cost about $100. The first thing I did was a quick scale sketch on a piece of paper, and then I started to work on my design using tinkercad and my digital caliper.

Electronic Fireworks Controller First Prototype

I have been playing around with the TinkerCad drawings as the parts come in. I have some left over pink and magenta filament so I printed the face of the controller so I could test fit some of the parts.

. . .

Electronic Fireworks Controller Final Assembly

With two days before the 4th it is mad scramble time. All the parts arrived and every thing fits. The first button and associated lights work correctly with the key and toggle switch, now I just need to solder the resistors and leds for each of the 12 buttons.

Electronic Fireworks Controller Finished

Done just in time!

Dymo LabelWriter 4XL Thermal Printer Ubuntu Setup

My LabelWriter 450 served me pretty well, but the smaller shipping label size was never adopted by anyone but paypal and I just wanted a printer that worked with the standard 4” X 6” shipping label.
