Psst! Looking for more? Check out the Tronxy P802M page with links to other articles about modifying and improving the Tronxy P802M 3D printer. In an attempt to improve the stiffness of the Tronxy P802M 3D printer along the x axis I printed a pair of corner supports I found on Thingiverse. As I half expected […]
Read More Tronxy P802M – Rigidity ModificationsWith my DaVinci 1.0 3D printer proving to be useless as a printer I was looking for a way to repurpose the machine. After creating a few electronics enclosures I needed a way to label the terminal connections and that got me thinking about converting the old printer to a laser engraver. A quick google […]
Read More DaVinci 1.0 – Conversion To Laser EtcherFor Easter 2017 I designed and printed half a dozen Easter Eggs. These eggs were designed to be printed on my new 3D printer with a single extruder. I printed one full egg in six different color and then swapped the layers to create the multi colored eggs. The eggs were then glued together after final assembly using superglue and scrap lengths of filament.
Read More 3D Printed Easter Egg 2017With my new Tronxy printer I was able to print the mounting hardware to upgrade the hotend on my DaVinci 1.0A to a E3D v6 hotend. Printing the Mounting Hardware I originally printed the mounting adapters by Thingiverse user oscahie, thing:707530. I found a few issues with this adapter during assembly and I modified it to better fit […]
Read More XYZprinting DaVinci 1.0A – Upgrade to E3D v6 HotendBend leveling on a 3D printer is an important thing and the adjustment should be as easy for the user as possible. The wing nuts that came with the Tronxy Prusa i3 P802MA are terrible; they are too small and difficult to use. To solve this problem and to start off my modifications for my Tronxy printer I turned a set of four brass thumb screws.
Read More Tronxy P802M – Thumb ScrewsMy 3D printer broke down and since I needed a 3D printer to fix it I purchased a inexpensive DIY kit. These are a few of my first thoughts. Also a quick word about connecting to Simplify3d.
Read More Tronxy P802M – Build, Setup, and Initial ThoughtsI aquired a car USB charger in need of repair and was inspired by a recent video from the EEVBlog to measure the power efficiency. The device become damaged when the insides flew out during insertion into the 12VDC car jack and the inductor was nearly sheared off the PCB. I was able to reinstall the inductor and slightly modified the circuit for easy measurements and connection to my DC electronic load.

There is something about LEDs and the joule thief circuit that keeps me coming back. This time around I went for something festive for the December holiday season along with a SMD transformer, no longer will I have to hand wind toroidal transformers.
Read More Single LED Joule Thief CandleSince June of 2016 I have been logging atmospheric pressure using a Raspberry Pi B+ and STEVAL-MKI165V1 evaluation module which features the LPS25HB atmospheric pressure sensor. The Raspberry Pi uses a small Python program I wrote to log the pressure data and time to the system SD card and also plot the past 24 hours […]
Read More Atmospheric Pressure Data Logging and DSTMy quadcopter has been grounded for over a week now. The last warm sunny day of October I went for a normal flight session only to find that the front right motor was not spinning. No spinning motor, even one, no fly. Back at the workbench I discovered that the ESC had given up on […]
