Today I received the order from MakerFarm. In the photos below you can see: the heated bed and the MDF bed mount; the control board (Printrboard) and the endstop switches; the J-Head MKIV-B hotend; timed bels and aluminium gears; screws, nuts and linear bearings; plastic elements, printed in “glow in the dark blue” ABS; stepper…
Today I received the rods (smooth and threaded) brought from Charlie’s 3d technologies. As Charlie suggested, for the Z axis I brought stainless steel threaded rods (instead of the zinc plated rods used for the frame) with 4 nuts, these too made by steel. I also included in my order two springs, useful to reduce the backlash.…
In the last few months, the ecosystem of “hobbistic” 3d printers litterally exploded: hundreds of different models are now available and this multiplicity may confuse someone who intends to build his first 3d printer.
My Nixie clock won’t have any visible buttons, so I chose to use a touch sensor, that signals to Arduino when the user touches the clock.
Today’s example is about a request I received from Francesco: how to choose the text to be shown on the display using a couple of buttons.
With this post, I’m starting my jurney in the 3d printer world: after having followed for a few the evolution of this technology, I decided to build my printer. Reading this blog you’ll follow the project, starting from the choice of the right model to its build and test… stay tuned!
Some readers wrote me asking more “real” examples using this display… in this post I’ll write a sketch to use it as a thermometer.
I decided to try the PCB service offered by OSH Park to manufacture the PCB for my Type4me project after having read good reviews about it; it was also recommended me by my friend Dario. OSH Park takes designs from many hobbists, panelizes them and – 2-3 times a week – sends them to the fab. For each design, you get…
A couple of days ago I brought an LCD keypad shield for Arduino. This shield, available on many Internet stores and on eBay, has an alphanumeric 16×2 LCD (16 chars for 2 rows) and a small keypad with 5 buttons, labeled UP/DOWN/LEFT/RIGHT e SELECT. This shield is perfect if you want to add a menu to your…
