Enginursday: Boulder Bounces

SparkFun recently teamed up with the Museum of Boulder to create a new exhibit called Boulder Bounces. It’s a re-creation of our Simon Says Soldering Kit, but using trampolines instead of buttons, and spotlights instead of LEDs. The purpose of Boulder Bounces is to augment another exhibit called Sportsology, which has interactive areas where people can learn about their own agility and test their strength doing various sports activities. The museum wanted to add something geared toward toddlers to this area.Digital mock up from the project proposalEmily Zinn, their curator of education, had been to SparkFun for a collaboration involving their new makerspace, saw the original Simon Says trampolines and thought they would be the perfect addition!The original Simon trampolines - currently located at SparkFunAmazingly, the original trampolines have survived almost five years since their original Dunk Tank Hack Installation – they have even been on tour across the nation a couple times!

Visualisation Device for Industrial Automation Using ML & Holograms

The concept of Virtual reality (VR) or the Augmented reality (AR) originated as early as 19th century and with the latter coming into more and more commercial aspect recently through the introduction of support with mobile phones, most widely used in small-scale gaming and entertainment predominantly. Augmented Reality which is still in its preliminary stages is tending towards a definitive revolution. Augmented reality by definition is the integration of digital information with the user’s environment in real time.Unlike virtual reality, which creates a totally artificial environment, augmented reality uses the existing environment and overlays additional information on top of it.The concept discussed here is about a visualization device or add-on based out of VR and AR as to how can we put it to good and ample use for visualization and also that of providing an augmented control for the industrial processes from a remote location with the help of these futuristic technologies along …

Experimenting with 3D Printing on Fabric

I’ve been seeing a lot of 3D printing on fabric around on the internet lately. I found this technique extremely intriguing based on my interests in wearables and combining tech and craft, and I was excited to try it using our Lulzbot printers.Before we jump in, I want to give credit to my inspiration. There have been tons of similar projects, but most credit for the development of this technique can go to David Shorey, who wrote about his work in Make Magazine. His work definitely piqued my interest, but I really decided to give it a go when I saw this necklace on imgur. I loved the idea of not only using this to make a scaling malleable surface, but also to create a visual floating effect against the skin.I started my experiments by following the processes I read about online. It’s pretty straight forward but it does take some finesse. If it was broken down into a step-by-step format it might look something like this:Make/download a model and prepare the g-code for the printerStart t…

Scaling Open-Source Conservation Technology

This post is part of a series of guest posts by GroupGets and their appointed experts to talk about project crowdfunding and early-stage product development, from successes to battle wounds.Conservation technology - software and devices used by professional conservation scientists to monitor animals and their environment - is going through a rapid change. Individuals with exposure to online maker communities are increasingly using open-source software and hardware to develop their own bespoke monitoring devices. These are typically much lower cost than commercial alternatives, and most significantly, can be modified and adapted to their specific deployment setting.For example, Open Acoustic Devices - a research project at the universities of Oxford and Southampton - have been developing a low-cost acoustic sensor called AudioMoth. In contrast to commercial devices, AudioMoth uses a low-cost sensitive MEMS microphone mounted directly on the printed circuit board to provide a single-boa…

Glaucoma Detection Using Support Vector Machine Algorithm

Glaucoma is one of the second principal eye disease in the world, if not treated legitimately may prompt to permanent blindness. There are no particular symptoms for this disease; it is seen by loss of side vision. It is a moderate dynamic decay of retinal ganglion cells (RGC) and their axons, bringing about a distinct appearance to the optic nerve head (ONH), frequently called cupping. Because of this cupping, the cup area increments and causes loss of side vision. Various modern methods are being developed currently for the efficient  glaucoma detection to name them, OCT, HRT.Usually to detect Glaucoma, optic nerve assessment is performed by a trained glaucoma specialist or using specialized expensive equipment such as the OCT (Optical coherence tomography) and HRT (Heidelberg Retinal Tomography) systems. However, optic disc assessment by an ophthalmologist is subjective and the availability of OCT/HRT is limited because of the cost involved. If the 2D fundus digital image is taken …

From Preventive to Predictive Maintenance

When we think of high-volume manufacturing, we often imagine a smoothly running factory with every machine functioning perfectly to turn out finished products efficiently and in volume. For the people running such a factory, their objective is to keep the factory running at its optimal speed with minimal downtime. This objective recognizes every machine with moving parts suffers some wear and tear and will inevitably need to be serviced or have some parts replaced. The question is when is the best time to do this: do you do it according to a fixed schedule or do you wait for the machine to start showing signs of failure?Approaches to maintenanceA first approach is to schedule maintenance tasks based on a fixed predetermined schedule, which ignores the actual condition of the equipment. Think of a regular car checkup at fixed intervals or mileage. This approach has the advantages of being simple to plan but also has significant drawbacks in that maintenance may happen too late, resulti…
