- This is an quite old project I made in 1996 but still interesting. It's an simple RDS decoder based on TDA7330B RDS demodulator and AT90S2313 (obsolete part, replace with Atmel ATtiny2313 ) controller. The RDS data is displayed on an 2 x 16 ...15-10-2007
- .. I have chosen the Atmel ATtiny26 microcontroller. It has some interesting features for this project: small and cheap 10 bit ADC sufficient IO pins, which can source and sink 20 mA; LEDs can be driven directly Possibility to use the ...17-10-2007
- .. on time (TON) is VIN=L×IPK/TON. For a supply voltage of 3 V, you should select an inductor with a nominal value of 10 µH and a saturation current larger than 1.5 A. You can calculate the microcontroller’s on time as 5 ...08-02-2009
- .. is typically on the order of 1 to 2 mA. Higher currents are available, but decreases the output voltage. A 2 kV, more than 10 mA may be possible depending on your particular flyback transformer input voltage and current. As you can see the ...05-12-2010
- .. This Instructable covers creating a USB connected Human Interface Device Keyboard that has 10 button inputs which are mapped to key combinations in the firmware. Key combinations can be quickly accessed without ...07-09-2011
- .. Kit. But there are various other devices that could be programmed onto this hardware/device, anything that could use 10 switch inputs. Included in the ZIP on Step 1 is the MPLAB project files, you must install the latest version of MPLAB ...08-09-2011
- .. operation. The circuit itself has such low leakage currents and trigger-current requirements that it can run the motor on 10 nA of current if you use a low-leakage energy-storage capacitor. Transistors Q 1 and Q 2 form a regenerative pair ...07-11-2017
- Mincior Vicentiu, Braila, Romania. Inside the case of a regular wall charger with a 500mA transformer I’ve built a source in commutation for powering 10W LEDs by using a TOP242 integrated circuit in the primary part and the LM393 dual ...19-12-2012
- .. the MCU (Figure 1). Optionally, a third I/O pin can be assigned to periodically reset the CD4017 (a cascadable decoded 1-of-10 Johnson counter) for reliable operation should an EMI or ESD event occur that could falsely clock the counter, or you ...11-03-2014
- .. for this and its worth to buy. Unfortunately, it is not very popular, and if you find it, it will have a tolerance of 10 to 100 ppm which is not suitable for any accurate measurements. If we have another device to measure the exact ...17-05-2013
