I have been trying to design a K9 for 3D printing for a while, even using Fusion 360 getting the body designed has been a stumbling block, On Facebook, there is a k-9 builders community and a link to an OneDrive account with 200 x 200 sliced STLs. I have […]

On LinkedIn a while ago Glen one of the reps at Würth Elektronik offered free PCB fidget spinners. I asked nicely if MiniBoyGeek could have one, and as such one was delivered, I am glad I opened the bag before giving it to him. A fun little build of 9 […]
I just realised that in Part 1 and Part 2 that I didnt discuse how to go from Datasheet to Fusion 360, While I am not going to cover how to do the drawing in great detail, there are plenty of sites which tell you how to make drawings in […]
One of the simpler inputs to add to a microcontroller is a switch, I have chosen to use the ones I have added to KiCad for my Swarmbot. Most people who add microswitches normaly use something like the following circuit on a Digital in Pin. When the Switch is open […]
I found the ‘Picktor’ Pick and Place head for retrofitting on a 3D printer on Thingiverse (GitHub) As designed it uses a Nema 17 stepper motor, however I suspect that will be too big for my design. I got 3 x Nema 14 stepper motors from an old RepRap Huxley, […]
Using a LED and a 560 Ω in most breadboard projects means that you end up with four pins connected for two components, soldering them up like this makes them much easer to handle.
Following on from last week where we drove a motor in one direction with the help of a simple amplifier, this week we are going to have a go at driving a servo. Those of you who read older posts in my blog will know I have done this before […]
In Week 2 we made a single LED blink using an Arduino, now about 99.9% of the time this would be overkill (the 0.1% of the time is when you are learning); actually tell a lie, There is a VERY good reason to flash a LED with a micro, but […]
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 […]
I found MCN Gerber Viewer, at this site, it is an OS X application for viewing and printing Gerber files, the zip of the app is Mirrored here. I have been working on PCBs more frequently, and along with Eagle this is a useful tool.
