I think you need a CMOS I think you need a CMOS inverter. Either a 74HC04 or (apparently) 74AC04. I think the clock is the biggest problem right now. Try the CD4009. It can’t hurt to try. Maybe it will work. If not, can you order from Newark, Digikey, Mouser, Jameco, Farnell, – …

Agree with botthoughts about Agree with botthoughts about using the 74HC04 or 74AC04. The CD4000 series has a maximum toggle speed of 5MHz, see Wikipedia . Don’t think it will work. An alternative chip would be a hex schmitt-trigger inverter 74xx14. It is pin compatible to the 7…

Good News! Finally!! found the 74HC04 and i got the respond! its full of 1023 data flow… i have to reset my atmega first to see the data… the next cycle will be full of 1023 data… like this 1023, 1023, 1023, 1023, 1023, 1023 1023, 1023, 1023, 1023, 1023, 1023 <reset> 386, 452, 1…

New sensor, this time data are coming, but all zeros Hello, I’ve managed to dismantle another Wiimote properly and have soldered the sensor to a piece of perfboard. This time, instead of having nothing, I have data flowing on my serial monitor but there are only zeroes. I have m…

zero data flows means :1. zero data flows means : 1. the clock is not sufficient to drive the camera ( in my case, using 24mhz crystal, kako schematic, 74ls14, just got 3 MHz), fixed by using 74HC04 and got around 22 Mhz with 15pF capacitor, 18Mhz using 22pF 2. the reset is not …

Dead sensor ? 1. I have used the updated schematics with a 24 MHz clock oscillator so I don’t think there’s an issue here. I would need an oscilloscope to check that. Might be my next purchase… 2. I think the reset is correctly connected. 3. I am using two pull-up resistors from…

Did you checked the pinout Did you checked the pinout of the clock oscillator? I remember CtC had a problem with his Wiimote boards using different types of clock oscillators . Using the 3.3V from the Arduino board should be ok.

Now it’s much better ! I bought another Wiimote and this time decided to solder some cables directly to the back of the Wiimote’s board to test the circuit prior to unsolder the IR sensor. And it’s working ! So one must be really careful when unsoldering - this is yet my third d…

connector ports I’m a little off-topic with this question, but this seems to be the most logical place to put this question. Has anyone found a source for the female port of the wii remote control? I’ve built an adapter to allow me to use the nunchuck as a USB mouse, and I’d l…

Blob size

Getting the z position trough blob size is easy. However the resolution is 4 bits only. Also, I have a jump between a value of 6 and a value of 15 when getting closer to the camera. I think I’ll use two IR sources with constant distance and calculate the evolution of the tracked distance to infer the distance with a better resolution.
