A Coding Dojo is a meeting where a bunch of coders get together to work on a programming challenge. They are there have fun and to engage in DeliberatePractice in order to improve …

Will regular leaded(or non-leaded) solder stick to actual tin or tin foil? Does the tin have a low enough melting point that it'd melt along with the solder? Has anyone actually tr …

Hi i bought this data logger a few weeks ago, http://www.littlebirdelectronics.com/products/Logomatic-v2-Serial-SD-Datalogger.html I've been having some trouble with it. I read th …

I'm trying to connect an RJ-45 jack with integrated magnetics (Belfuse L829-1X1T-91 datasheet) to an Ethernet PHY chip (Micrel KSZ8041TL datasheet). The TX+/-, RX+/-, and the LED p …

I want to do PIC programming in embedded C. But I don't know the language well. Please help me by suggesting some good sites for getting an idea about C programming.

We used an Asian design house to design, program and build our custom MP3 player. The chip we used (Sigmatel) is no longer avaialble and the DH does not do this type of work anymor …

I was implementing the ALU from the specs given in my The Elements of Computing systems book. I am stuck on only one problem. How do I find if a given number is zero or not. One th …

This feels like a dumb question, but I'm going to ask it anyway. If a crystal has a rated load capacitance of 6pF, is the right thing to do to put a 6pF capacitor to GND on either …

What methods and equipments can I used to measure and record the current variation of CNC servo motor while machining.

Hi folks, Using a PIC16F886, I am trying to generate interrupts every 100 milliseconds using TMR0 clocked from the internal oscillator, but I am getting some really strange behavi …

I've heard rumors that the power line frequency is kept stable and accurate by syncing it with atomic clocks. Is this true? What kind of accuracy does it have? Is this true ever …

Hello all, I am thinking about starting a project and was just looking for some general input. Where I work our company currently have remote stations that take data in from a rad …
