I'm tired of the buzzer in the microwave oven that is beeping constant u p to a minute.So I opened it up like any normal hacker would, found the buzzer and snapped it off.Sure, the buzzer was irritating, but so would be not to hear when my food is cooked....
This idea was inspired by Russell Durrett's Light Bulb PCR Machine. http://russelldurrett.com/lightbulbpcr.html I decided to attempt to make a similar device with parts I already had on hand. I replaced the light bulb with a 3D printing heating element...
Having a dated car and finding spare parts can be difficult, especially when such a simple element as a hatch button is molded in a meter-wide, monolithic and model-specific plastic part.I couldn't hope to find this part in a scrapyard as they probably...
The display (which also serves as the main structural element) comprises 3x Neopixel 8x8 panels. This element was originally going to be fulfilled by colourduinos but they didnt offer satisfactory results despite the higher pixel density and having square...
Nothing Fancy about this one.Uses an Arduino UNO clone (more on that later) to read a one wire temp sensor and drive a relay to disconnectpower from the choke heater element for a couple of minutes on cold mornings.The Craburettor in the VW Beetle has...
IntroThere are some very cheap soldering iron handles available as spare parts. They usually work with 900M type tips, the heating element has 50W at 24V, and the temperature sensor is a 40uV/*C type K thermocouple integrated into the heating element....
The antenna uses 'choc block' type screw terminal connectors that are held to the boom by zip ties. They allow the individual elements to be slid in and secured in place with a screw driver by tightening the screw terminals.When it's time to pack up...
The peltier element comes from a mini fridge i found in the dumpster. It was used to cool a swedish type of tobacco called snus. The cooling module was in the bottom and on one side was the black cooling element that you see in tho top of the finished...
A single 5V supply runs the light show. It is regulated to 3.3V for the Z8 and temperature controlled crystal oscillator. The 5V input is also monitored by an input on the CPU, triggering a low power mode if the 5V source is lost. The backup power could...
This project implements the CipherSaber-2 encryption algorithm. It is based on RC4 using a passphrase, with a 10 random byte Initialization Vector appended to the key. The initialization stage of the cipher is repeated a number of times (10 minimum)...
CTM encompasses a hardware and a software element. The hardware element is comprised of the component listing in the project page. The board accepts commands over USB and directly signals whatever soundchip you load the board up with. The boards are...
Short demo video: ---------- more ---------- For this I took a single TEC2-25408 Peltier element, which sits on a Thermalright Peerless Assassin 120 CPU air cooler. On the cold side of the Peltier sits a 100 x 100 x 2mm copper plate into which I drilled...
In this project I will take a conventional toaster oven (any kind of toaster oven can be used) and design a precision controller to turn it into a reflow soldering oven. I know there are already plenty of controller kits available out there, but I hope...
The brains of the operation is the Raspberry Pi. As of right now, my platform of choice is Windows IoT. Why? Because I didn't know any better. Also, it's actually not that bad for a novice programmer like myself. It will be doing all the hard stuff,...
Efficiency targeted features: - magnetic bearings, maglev using permanent magnets to suspend the z axis and keep the x-y position of the shaft stable. - omni directional wind harvesting, either with a helical vane or impeller design / fixed wind guides.-...
