    Ideas For Delayed Bright Spark / Pop Sound Static Gap Capacitor

    You will find here under a circuit based on a capacitor discharge to simulate a starting pistol. The circuit is however not for beginner as high voltage is involved. If you don't have the required skills or if you can't hire them please DON'T build it ! Another approach can to record the loud...

    Hobbyist Techniques for Reflow?

    I have seen solder plate method videos and its look pretty good. I have personally used the paste (via a dispenser) and a dedicated oven. Results are correct but I still prefer the plain old solder iron method up to 0402 size + desoldering braid and flux for fine pitchs IC. I apply a simple...

    how to change schematic capture(ISIS) to pcb layout(ARES) in proteus software

    Don't sure about what you mean by"change from schematic to PCB". It's not specific to Proteus but the schematic is the graphical representation of an electrical circuit where the PCB is his physical implementation. To go to this physical implementation a net list must be generated and imported...

    Depth & Angle/Arc "sensors" (?) for Project?

    Depending of your project goals this kind of technology can be used: http://www.electronics-lab.com/blog/?p=8370 Will be more scientific/experiment purpose as the ball will not be certified for a "real" game, no need for fixed infrastructures however. Olivier

    Custom PCB

    @Dave, don't know about Protel file but it should be possible to generate, CAD package independent, Gerber files. @Dan, 1 or 2 layer is the same price because the 1 layer process almost disappear being fitted in the 2 layers board process with non plated holes and "blank" top layer. Olivier

    Which MC should I get?

    You can maybe consider a wav player, no need to decode MP3, a simple RC filter is to be added, combined with a serial data flash it will be a low part count setup. Here the code (in Basic for AVR)...

    Custom PCB

    I use those guys time to time: http://www.seeedstudio.com/service/ They deliver nice value for money pcb's. It's 10$ for 5 pces of 5X5 cm 1or2 layer PCB. They are delivered in around 3 weeks (to Belgium) cheers, Olivier

    Next/previous switching a multiplexer

    Regarding the non-volatility one idea can be to store the last selected input on analog form. An Up/down digital potentiometer with storage eeprom like the DS1804 can be used. A counter can increment few steps each time the up/down button is pressed. The potentiometer voltage can be "decoded"...

    Simultaneous events

    You can for sure have the USB cable directly connected to the PCB, however keeping the connector( ideally close to the pin 23-24) keep your options open as you can solder the cable in the connector holes anyway. You can also move up the 4021 close to the pin's 40 -->30 and just leave the crystal...

    Simultaneous events

    Hi, You also have to follow rules to route the USB port. see http://www.focusembedded.com/blog/high-speed-usb-in-a-two-layer-pcb/ or http://ww1.microchip.com/downloads/en/AppNotes/an1517.pdf It's not specific to PIC µcontroller but something linked to USB specifications. The USB connector...

    Echo canceller Schematic

    Echo canceling is not an easy task, the most powerful way is probably to implement algorithms in a DSP. However dedicated IC are available like this one: http://www.cirrus.com/en/products/cs6422.html The ressources tab is good start. Olivier

    digital multimeter sinclair dm 450

    You can directly connect a few hundred mV source on the ICL7103 inputs (pins 10&11) but this should not help to solve the flickering display issue. Few pictures of both PCB's sides can help us to find what is all about. For instance are the IC's or the displays socketed ? Old HP displays pins...

    Transmitt ASCII data

    You can maybe first check the BT module alone (if not yet done) by checking is bluetooth address (BD_ADDR) via the dedicated command for example. Also the CTS-RTS pins must probably be jumped. You can also test the BT module with a wire ended FTDI 3V3 USB /RS232 adapter and a terminal PC software.

    LCD screen and screen connector help

    Those cables are called FPC. They are many variations based on the picth, the side where the contacts are located and of course the contact amount. You can find them all around the web. But be aware that those LCD displays are not standardized at all ! The pinout, the controller, the signals...
