I make sensors by cutting the top off of a metal power transistor and using the base-emitter junction as a PIN diode. This works very well for detecting Alpha particles (and photons).Alphas would be blocked or attenuated by an oxide layer,...
I'd like to "improve" MCH heater (50*50*1.5mm) for DIY reflower: add panasonic PGS on top side and aluminium foil on bottom side. That requires glue, operating at least on 300C, ideally up to 400C. Also, this glue should dry without air access and be...
Any idea how to get a sample?No really, does anyone work at a biolab and can get one?I have a huuuuge Pothos at home, they are super hardy and low maintenance and great for hackspaces, outside of the cleaning-chemicals-we-frequently-use thing.
Integrating IR 38(-56)kHz + AM 433 MHz + 868 MHz (+ 915 MHz in jurisdictions that have made this an ISM band too) + 2.4 GHz OQPSK remote controls preferably within one instance of LIRC on a headless 2W board.See also http://dangerousprototypes.com/forum/viewtopic.php?t=431#p3702...
I'm looking for inspiration to export data (simplex) / one-way) across a short air gap from a small device with a low energy budget, so trying to optimise for power. BLE seems like overkill and potentially too complex for the relatively quick development...
Last night made the attempt to include several images onto my Hackaday project pages but ran into a wall. The images taken were all larger than 3mb in size and the system declined them. For the camera, used my iPad Air, but didn't see a way...
This is the idea, for a RC flying toy:A single propeller, or a small centrifugal compressor blows air into a reservoir which is the body of the flying machine. The reservoir can even be made of textile material. So it will...
The North County Mini Maker Faire is back; co-hosted by the San Diego Maker’s Guild and the Antique Gas & Steam Engine Museum. This weekend event falls on Father’s Day Weekend, June 17-18, making it a perfect family event.The Mini Maker Faire is a celebration...
I'm looking into what engine to put in my boat. Marinised engines generally have several parts water-cooled that are usually air-cooled on an auto engine. The most extreme of these is the exhaust manifold - in a car, there is constant air...
I will be using sensor MiCS-6814 for measuring concentration of gases. So how to interface with microcontroller and how is the working of sensor.I have downloaded the datasheet but i have few queries like,1. I got the circuit of interfacing from...
I'm looking for a crash data recorder from an automobile that has actually been in a collision of some sort. These are devices in a car that record various sensor data in a first-in-last-out memory that can be read back by law enforcement or insurance...
The unofficial story of the A-10 Warthog, a very cool amalgam of technology begins with GE. Yes, General Electric, they bring good, and sometimes dangerous things to life. You see, they built an amazing chaingun cannon. This gun chews...
Hi guys,if you know FSRs, you know they are really expensive. If you need just one, maybe you'd better buy a professionally made one. But if like me you needed more than 10, well price becomes an issue.I have an idea on how to make cheap FSRs that I...
The Youtube algorithm just brought this awesome tech to my attention, and already I'm thinking about trying to build one :) Basically you use a relatively low pressure water jet (50-800bar according to Synova's site, as opposed to 2000-6000bar for regular...
