    NL5 Circuit Simulator

    Very interesting simulator. I havent got time to test its quality/reliability yet but looking at the components' properties I see this being a great tool to test funtional units or systems. It is not a subsitute for SPICE though.

    how to use the transmitter and reciver modules

    You have to digitise the audio signal using an ADC then serialise it and send it to the TX module. Then receive it at the RX module, deserialise it and use a DAC. This will make such a bad quality system for too many reasons to post here. I suggest you build a ready made audio transmitter.

    Problems with logic and control... can you help?

    Yes, this is the job for a Data type flip flop but you can wire other flip-flops to do that as well. Anyway, your thinking is right, you have probably made a mistake with your hardware. Can you post a schematic of how you would wire your D-flip flop? Whats V+?

    how many 10v leds for 230AC and a few other questions.

    I classify them as (there are always exceptions): Electricians that install wiring and electrics in buildings from tables they have memorised. Electronics repair technicians that repair your TV using using memorised tables and a fair amount of original thinking. These could install their own...

    AC power outlet

    Hello Kevin, If a normal person, not a general purpose silicon diode, has one bipolar transistor in each hand, and two capacitors on each foot how many components does the person have? Microwave magnetron voltage multiplier... Thank you Alex

    Designing generators

    The output power of a wind generator is a function of wind speed, blade design and number of blades,dimensions, air temperature and efficiency of the generator and the system as a whole. You can increase the power output if you increase the efficiency of the generator. This cone be done with...

    locator help

    You are lucky. Buy this Elektor issue (a few punds) as it is a good magazine for hobbyists. The issue is December 2006 of Elektor (UK publication) www.elektor.com What do they say? :P

    locator help

    I can bring you in contact with an IT services company that amongst others, do location tracking based on WiFi mesh networks and watch-like wearable units. They originally developed the system for security personnel in open-air events. Interested? Edit: I see this is not for a professional...

    locator help

    Who is the project for? GPS will not work as you are in a building. It might work but the accuracy will be low and sometimes you will lose signal. Does the building have wifi coverage?

    Design new 0 to 30V power supply.

    We have a problem as many pages are missing. From other topics too. I can't think of a reason to have max volts/amps. Maybe we could say CC/CV for each channel?

    Adding a Digital Multimeter LCD to XP-720

    Hero is right, we need the schematic of the XP-720 power supply. Also I dont know if you have noticed Hero but the current sensing resistor is connected to an LM337, not an LM317, which makes this a very weird circuit. I bet S1 and S3 cost nearly as much as a second DK203.

    Design new 0 to 30V power supply.

    You will probably find that less current will be needed. Most of this will be going to the LCD backlight, about 20mA. Digipots will draw about <1mA (excluding resistor ladder). Dual or more versions can be found. The MCU itself needs not run off 5V (the LCD accepts TTL signals). It can run at...
