To encode the Hardware Revision number, so that we know what the version numbers of the main PCB is and is available to the Microcontroller.
After AC Rectification, the next step is Reducing the Ripple on the DC supply line as much as possible.
AC (Alternating Current) is used for the transmission of mains voltage, one of its main advantages for use as a method of transmission over DC (Direct Current) is that a change of voltage between High Voltage, Low Voltage, and SELV (Safety Extra-low Voltage) can be performed using a transformer. A […]
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 […]
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 […]
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 […]
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.
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, […]
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 have been trying to design a K9 for 3D printing for a while, even using Fusion 360 getting the body design has been a stumbling block, On Facebook, there is a k-9 builders community and a link to a OneDrive account with 200 x 200 sliced STLs. I have […]
Ohm’s law (sometimes written as Ohm law or Ohms law) is one of the fundamental first principles of electronics. The law was named after the German physicist Georg Ohm and states that the electric current through a conductor between two points is directly proportional to the voltage across the two […]
