Transmittance and reflectance are two basic types of photoplethysmography. For the transmittance PPG, a light source is emitted into the tissue and a photodetector is placed on the opposite side of the tissue to measure the resultant light. Because of...
After ripping out everything off the plastic frame, it's time to start installing the necessary components and testing that they work. Rewiring the motor, circuit board and mechanical assembly together, I found that the original grease was solidifying...
As I am going to often use this for soldering work, the plastic platform is not an ESD safe working surface. Using some scrap rubber ESD mat, I custom cut and grounded a mat for the platform.Cutting the mat is quite simple with utility scissors. I added...
While brain storming sources of feedback that could be put onto the robot, We came up with a barometric pressure sensor encapsulated in a form of rubber. After researching a number of pressure sensors a highly sensitive, 24bit MS5611 pressure sensor...
The dream of improving the sandals continues to give way to the need to keep the current fleet alive as it wears out. It came to pass that a $40 sheet of soling material became cracked from being stored in a folded position. This sheet only yielded 2.5...
Sorted out the pitch changes needed to make #MPRT - Modified planetary robotics transmission mesh without interference. Two layers, two different gear pitches. Added it. I think I may still add a carrier for the planets as I actually...
Hi everyone, welcome to Hack Chat. I'm Dan, I'll be moderating today for Adam Zeloof as we talk all about mechanical engineering. Is @Adam Zeloof logged in yet? Adam Zeloof12:01 PMI'm here! There we go. Hi Adam, welcome to the chat. And welcome to the...
small vibrating motors: ~84c each (ebay - $8.36/10)LDRs: ~5c each (ebay $0.99/20)Simple SPDT switches, ~10c each. (ebay $1.86/20)Toothbrushes : ~17c each (dollar store $1.00/6) 2xButton cells: 25c each (dollar store $1.00/4)And creepy crawly to go on...
A resistive sensor, also known as FSR (For-ce Sensing Resistor), is a polymer film device that exhibits a decrease in resistance when the force applied to the active surface is increased. FSRs are not load cell or strain gauge gas although they have...
[En svensk version finns i slutet av inlägget] Background Two years ago I bought a boat with the hope that someday be able to electrify it. It is a displacement boat of a type called snipa or snäcka which typically has low drag at low...
This was the most important part for me because I wanted a variety of target options. This is what I had to work with and this is what is does:1. The ancient Vivitar flash slave is only triggered by a flash from a camera (or staff flash in this case)...
It's been a long time since I have updated this, mostly due to the lack of internet at home, and the death of my laptop. Main computer has died, using my home theater PC for now.Anyway, truck stuff. The cheap, bent, Summit Racing distributor has been...
07/17/2017Description of operational aspects of the 3D printable Raman SpectrometerOperational Manual Part II am including this brief explanation for some of the operational aspects of this project so it's functions and interconnectivity is less ambiguious....
When designing something new there's always things you didn't know that come out during testing so it's incredibly important to put together a proof of concept to learn as much as you can as quickly as you can. The first version of the launcher was always...
This is the motion control headset I put together for controlling my Dalek dome. It tracks the motion of the wearer’s head around 3 axes, though I only use two for the the Dalek.The basis of the headset is a protective face shield I had lying around,...
