It has been one hell of a long time since I last posted and sadly this will just be a short one, I hope to get some posts up soon! I have a ton of MY6812 motors that were originally intended for a hexapod design of mine (and still intended to) of which I want […]
Preface SR (switched reluctance) motors are pretty amazing things. Originally developed in 1838, an SR motor uses some of the simplest principles of electromagnetics – energize a coil to create a magnetic field and magnetically permeable materials (i.e. some steels, nickel, iron, cobalt etc) will be attracted to it, similar to how a standard solenoid […]
The robot so aptly named MechaCrab. This is my first attempt at a 2 DOF/appendage soft robotic quadruped. I’ve been mulling this idea over for a while as it came out of my initial designs of TAMI (I will get back to that project at some point…). The idea is to use 2 DOF soft […]
For once, I have actually decided to be proactive regards to actually writing software (shock horror!). I decided as I’m going to be using a PI for this project, I should probably learn Python finally. It also gave me a good reason to figure using FEA within FreeCAD, something I’ve been meaning to do for […]
The main part of this project has been designing a suitable bone capable of being 3D printed. The preface to this project can be found here. My first bone design was completely from scratch with no prior thought into what it would respond like. I came up with this design solely to get some 3D […]
I’ve been very quiet on the writing front. It seems a full time job and life to live doesn’t leave much free time for writing – at least for me. This is a project that’s actually been in the pipeline for years. It originated with myself and a friend perusing the idea of robotic human […]
Preface I’m currently doing a project that uses a tiny SSD1306 based OLED display. I’ve searched all over the internet but couldn’t actually find any data on current measurements done by people so I thought I’d do a couple and put them up here! The OLED I’m using is a standard 128×64 pixel version that […]
Long time no post! Now that’s out of the way… As ever, I’m always on the search for cheap electronics and this board is nearly mind blowing given both the price and form factor you can get it in. Enter the Gnarly Grey UPDuino v2.0 based on a Lattice iCE40UP5K FPGA featuring: 120Kbits of BRAM […]
Its been one hell of a while since I posted a tutorial so I thought I’d throw one of up for this. I’ve not had much time to do much electronics as of late (it is now my job…) but hopefully once I move into a new area, I’ll have a little more free time […]
Its been a ton of time since I last did any updates on the ol’ human sized hexapod! I finally decided to go for dedicated motor controller ICs (Allegro A4950) as opposed to a discrete solution. These chips were pretty expensive (~£27 for the entire board…) driven by an STM32F030 once again generating software PWM. […]
