When designing boards, one of the things I spend a lot of time checking is if my UART transmit (TX) and receive (RX) lines are the right way round, or switched over. When the design gets to the printed circuit board (PCB) level, it can be nearly impossible to rework. […]

This looks like a way to allow for addressing nodes on a CAN, RS485 or DMX network without needing to use either DIP switches or PCB changes.
As part of my K9 and ROV projects, I am using at least one Arduino to control components such as the K9’s ears. Since the Arduinos will be fixed to the robots, I will program them via the Raspberry Pi. The version of Raspbian I am running is Raspberry Pi […]
Today’s Makevember There seems to be very little consensus on the arangement of the colours of the buttons on the back of K-9, K9 has a 4 x 3 array of buttons on his back, I am using this image Binary kitten got me from the k9 at the Doctor […]
Following on from my Makevember post yesterday, where I tried to make turbine blades, and Failed… I fed 6050 from SG6050 into Fusion 360 and this is what it gave me: SG6050 profile To check it wasnt it that was broken, I ran the script with the defult value of […]
I missed a Makevember post yesterday, and the one for today is going to be quite virtual again… Last time I did a post on K-9’s Back it was to work out how to read the buttons, and to do a first draft of the CADing up for the 3D […]
Another boat: I was trying to dial in a 3D printer, the blobs on the hull seem to be caused by buffer under-runs from the Raspberry Pi. In the last Makevember post, there were some strange shaped Duplo links, here they are in use:
I have been back in Fusion 360 designing parts for my wind turbine: These are parts of the hub, they are the bearings 3D printed to be the size of F 6902-2RS (15x28x7 mm) bearings that are commercially available, the printer settings have been edited slightly, so I still have […]
As in my Q-Blade Post 1. I made reference to both HAWT (Horizontal Axis Wind Turbine) and VAWT (Vertical Axis Wind Turbines), A standard VAWT design has been covered by the Ultimaker Blog: There are several other designs that are more novel. One of these novel approaches is the O-Wind, […]
A while ago I picked up these buttons for my Dr Who’s K-9 robot from AliExpress, Hobby Components have similar available online, The ones I purchased are SPDT with a 24 V DC incandescent bulb in them, regardless of the button colour they are all illuminated with a white incandescent […]
On Boxing day, Tamarisk, MiniBoyGeek, and Granny went for a look round Warwick Castle, We also saw the Mill and Hydroelectricity plant on the river Avon
