Hi, this project is a gift to a friend. I m building him a nixie clock with some specs.- Time- Alarm- Color (Led + UV reactive paint + eventually bar graph in 9)- Wifi (openwrt backed on a wr703n)- Video (optional)Right now i received the board, cleaned...
In this step we are going to add phpMyAdmin. This software is a GUI for our browser that enables us to manage our mySQL databases. We are able to setup users, passwords, permissions, manage databases and most everything else you can do from the command...
I purchased a couple of 8x8 LED matrices. The LEDs are controlled by a MAX7219 chip with a SPI interface. In the video below you can see the results. I chained two matrices together to form a 8 x 16 grid. The vertical direction represents the download...
Well I caved and purchased a mid tier Proxxon rotary tool and matching drill press and mini vise. I already had acquired a Proxxon KT 70 compound X-Y table before which works with the press as well.This tool is far more stable, with minimal run out compared...
Got the gantry assembly started. Just a couple of 2 x 4 x 11.75 (gantry feet) at the base which are screwed to the drawer slide. Each vertical support of the gantry is a 2 x 4 x 20. I used 2 pieces of mdf one at the top and one one the front of the 2...
Now to mix everything in a functional package. I had great difficulties there, as some code from the examples was still there, it happened there wasn't enough memory for some tasks and Arduino failed silently but with side effects like not displaying...
Since this project is all about watering the lawn, I thought it would be a good idea to see how well a gravity fed system would work. In order to perform a truly empirical test, I decided to test the water flow independent of the bot. I plumbed the storage...
Once the basis of the Adaptator X was created, an electronic system was added to control the rise level of the horizontal bar holding the phone. The main board was pierced, and a flexible camera tripod was fixed to it with screw and bolt.An Arduino Leonardo...
X- and Z-axes both seem to be surprisingly stable and wobble-free (except for a slightly bent Z screw which I'll attempt to straighten later). However, the Y-axis has a distinct wobble, so straight edges aligned with Y end up slightly wavy. The fault...
ElectronicsTested the photo diode sensors on Version 15 and was not seeing a high enough voltage for the ESP8266 to get the high input. Decided to run the the resistor before the sensor instead of after. Breadboarding it showed promise and so I redid...
I fabricated the cover for the theta drive belt and home sensor this morning.This is the complete mechanical system now. The tripod is interchangable with my previous version, avoiding one more piece to build. The complete system with the antenna is...
For the actual gimbal structure, I used Actobotics aluminum plating and pattern adapters from Servo City. The entire Actobotics line uses 6/32 threads for everything that is threaded (except the weird stuff). For fasteners, I used the new 6/32 stainless...
Big news today. I pushed the design and code for tCam mini to the github repository (new section: ESP32).I've also been busy putting the finishing touches on the companion desktop application and binaries for it are also available. ...
After some back-and-forth where to assemble, I finally uploaded my Gerber files at my usual go-to-shop and now waiting for the whole thing to ship in the next weeks (hopefully). Here is a KiCad rendering how the board currently looks like: To make good...
If I ever have the opportunity to make a version 3 of my cnc I would make several changes to it. I thought it was time to document some of those tweaks now, while they are fresh in my head.I would get rid of these 12 mm rods and go with...
