Most chips have multiple power pins that need to be connected to the same power supply, but Eagle doesn’t allow you to give 2 different pins the same name. This short tutorial shows how to get around this and name multiple part pins the same thing. Keep reading below, see our other Eagle tutorials here.
We are off to the Bay Area Maker Faire, and we’d like to share some of the tips we picked up on our previous visit there. Below are our tips for both visitors, and participants. If you are in the area be sure to drop by.
Raj wrote a tutorial on how-to implement servo control on PIC16F microcontrollers. The article starts off with some servo theory, and is followed with an open source practical example. A servo motor is a special geared DC motor equipped with an electronic circuit for controlling the direction of rotation, as well as the position, of […]
Eagle’s popularity is partly due to the sheer number of parts and footprint libraries available for it. Sometimes you can’t find the part you need in an existing library though, and it’s time to make your own. Making a new part in Cadsoft Eagle can be intimidating for new users, but the guide below shows […]
A while back we started selling Bus Pirate v3.5a-SOIC “DIY Edition” PCBs from the free PCB drawer for $3.95. Our informal survey and found that $5, including shipping, is a sweet spot for one board. So we hacked Zen Cart to accept PayPal for only one item, and started taking orders. With shipping, two boards […]
There are many ways to built a DIY PCB. Some of the more popular ones are the toner transfer method, and the UV exposure of PCBs. Both methods require lots of trial and error. Here is another way to go around building you PCBs. Pourcirup posted a tutorial on how to convert an old ink-jet […]
Chuckt asked what goals important to master microcontrollers. There’s been some good suggestions so far, which are consolidated on the wiki: Basic Pins/port/direction (LED flashing) PWM (LED intensity) Advanced UART communication (when and how to use max232 chip) SPI communication I2C communication CAN communication Interrupts (pin – detect button press, UART – communication) Hardware timers Interfacing an […]
Here’s how a PCB is made: Last year around mid-November Eric and I (Base2’s owners) were in the Denver area and were fortunate enough to be able to visit the circuit board manufacturer that we frequently use – Advanced Circuits. They were kind enough to give us a tour of their facility and explain the […]
Simon explained in detail on how to update the Bus Pìrate from firmware v3 to v5 easily. Get your own handy Bus Pirate for $30, including world-wide shipping. Also available from our friendly distributors Adafruit, Open Source Control Systems, and eHaJo.
Hack a Day has a how-to on programming PICs under Linux with the open source SDCC compiler.
Don’t miss Mike’s tutorials on AVR microcontrollers at Hack a Day. Part 1: introduction Part 2: the hardware More to come.
Michal Demin posted a tutorial for the OpenOCD JTAG debugging support he added to the Bus Pirate. Some time ago, I have added support to OpenOCD to be able to use Buspirate as JTAG interface. This how-to will show you, how to setup all the things necessary. Things you will need: – Buspirate – Computer […]
