Anthrophex – Linear actuator feedback

Obviously having feedback for each of the linear actuators is a pretty big requirement (though not essential realistically for the leg lifting actuators), therefore a fair bit of through needs to go into this section. I was originally going to use flex sensors on the joints to measure the angle of each joint but after […]

Anthrophex: Part 2 – The build

I guess now would be a good time to disclaim my machining abilities. I can safely say that I’d make a shocking machinist but I guess its the effort that counts right? Regardless, with the arrival of parts, the build could begin! The leg and hip hinges As all of the aluminium was pre cut […]

STM32F0 CubeMX Tutorial 1 – GPIO

It’s certainly been a while since I wrote a tutorial, a lot of the STM32 ecosystem has changed and its probably time I changed with it. CubeMX was developed by ST to streamline application design and creation. It allows for a visual method of generating initialization code without needing to know the ins and outs […]

Ochi – Version 1

A couple of weeks back, I posted about designing a pair of smart glasses. Now that university has finished for the year (results tomorrow!), I’ve had a lot more time to work on my glasses – though I started employment on Monday so I’m not completely free. I have however been developing both an app […]

STM32F0 – Software capacitive touch

Capacitive touch is “rad”. By utilizing one of the simplest physical characteristics of an object – charge storage, one is able to measure the presence of a grounded object including touch and pressure. There are a couple of capacitive touch libraries that I’ve seen around but many require dedicated hardware, for example the TSC peripheral […]

Ochi – Smart glasses

So I’ve made a smartwatch previously and while they’re cool and all, they had nothing on the hype created when Google Glass first came out. For reference, Ochi is eye in Romanian – there is no language preference, I just thought Ochi was a pretty cool related word. While I’ve wanted a pair of Google Glass […]

STM32F0 Simple Boost Converter

Having changed my degree title from Electronic engineering to Electrical and Electronic engineering, means that I have to take some power modules. While I don’t find mass power transfer particularly inspiring (HVDC links, the grid and power networks blah blah blah), I find small power conversions pretty interesting, the low power stuff that enables us […]

STM32F0 – High sample rate ADC usage

My current university project is based around non destructive evaluation using ultrasonics. I’ve been delegated the task of trying to design a suitably cheap (cheap being my speciality 😉 ) low end ultrasonic evaluating system. This involves designing the high voltage supply, the output driver, a high speed amplifier system AND the whole digital domain […]

Eon V Smartwatch!

Well after months of waiting and designing, I’ve finally managed to build the Eon V smartwatch! Why its version 5, I’m not to sure other than other few that actually worked though five sounds good so I’m going to keep it. I came across a fair few problems with the implementation of this watch, predominantly […]
