With a CNC the main goal is to get a platform to a location. This location can be specified by different coordinate systems. Currently I'm limiting the aim to a 2D plane. Most hobby CNCs use the two drive axis as the basis for the CNC's coordinate system....
So i really wanted a warm cookie at my desk one day.Rev-01so i took apart a cupcake tray and got the cup. I wrapped a beaker warming nicrome wire around it and cemented it in place with fire place caulk. It was a 150W heater and i found although it cooked...
OverviewWhen starting #Goliath - A Gas Powered Quadcopter, one of the goals was to use off the shelf hardware. After looking at propeller/rotor from traditional aircraft suppliers two issues became readily apparent. The first issue was that the cheapest...
Heating regulation system include features:- Starting procedure- Stop heating- Shutdown- Overheating (emergency)- UPS cooperation for emergency stop- WiFi LAN connection for remote command lineThere will be Stage two to use practical experience from...
The sound samples are free samples from musicradar.com. They are assembled in one 8-bit, 11.025 KHz mono wav file with silence as separator. I slowed the samples down and toned them lower before converting them to 8 bit, because the drum kit can run...
Time: Mon Aug 21, 2017, 12:00PM - 4:00PM Location: Jordan Hall of Science On August 21, 2017, the shadow of the moon will draw a path across the continental United States, from Oregon to South Carolina. On campus we will see the moon obscure...
Internally, the HTML structure and the low-level JavaScript is intended to mimic the operation of addressable LED strips very closely. The main difference is that the browser implementation is not timing-based -- we take more of an ad-hoc approach, and...

This is the output you will get from the from the Yagi Calculator. These measurements are only valid for a 3/4 in (19 mm) boom and 1/4 in (6.35 mm) elements. VK5DJ's YAGI CALCULATORYagi design frequency =725.00 MHzWavelength = 414 mmParasitic elements...
Automated Distiller v1 - July 2011 I discovered the cheap tabletop distillation unit that I purchased had a few design flaws. The most common problems being the circuit breaker failing and the heating element cracking. With the heating...
To know the current satellite position, the ESP8266 first gets a recent two-line element set from the web. Then it uses the SGP4 model to calculate the current satellite position. With the model and some extra algoritmes, it's able to tell if the satellite...
My previous creation of CPLD board in the above picture is surely working for VHDL training, but it is too simplified and we need wiring of switches and LEDs for testing the results. Indeed the macro-cell in this CPLD is just 36 and just switch and LEDs...
This video documents the prototyping, building, unit testing, and final assemply of the sculpture. Admittedly the final circuit is a mess. As an excuse for my lack of effort at beautifying it, this is in keeping with the types of hacks my Dad would come...
After made a little arm robot on a RC vehicle, my little daugher destroyed the servos in less than 5 minutes :-( I thought of a solution to avoid this and I try to add a belt-type elastic element between the servo and the actuator: it seems to work pretty...
