Hi,
Please explain a bit more about force qauge? I thought that piezoelectric sensor IS a simple force gauge. It outputs a small voltage proportional to impact on it's surface.
What obout resistive sensors...like flexisensor I found from website
The FlexiForce single element force sensor acts...
I'm also interested to build something similar. The idea is to attach a force gauge directly to surface of punch bag. MCU (Atmega) will function as a standalone data recorder or interface to laptop data acquisition system. Maybe latter is easier.
What is needed
--- The sensor itself...
Well..the defected part was not the lamp drive. It was the main power supply.
And it was only partly broken. The stanbd by 3.3V supply was still working so it appears to be OK. But when pushing the ON button it didn't start the main supply at all. Couldn't find the defected pars so I had to...
smd switching regulator datasheet
Hi,
I have a defected powersupply from my Panasonic PT-AX100e projector.
Switching regulator is a small 8pin smd IC. I can see the type is IH07408, but I can't find datasheets anywhere. The power-unit order code is ETXMM636MCHA. Any idea?
Thanks,
Mark
panasonic pt ax 100e
Yep...my projector died. More specificly the Lamp HV power supply broke down. Or that what I assume since no voltage is coming to lamp connectors at startup.
Service manual or schematics would be great help. Any help appreciated
Thanks,
Mark
measuring impact force
There must be commercially available load cells or srain sensors to connect via some usb datalogger to laptop. Is there any cheap and simple DAQ systems available?
how to measure impact force
Hi,
I would like to hook up a system to measure impact and draw a graph on laptop screen. I'll need a sensor (maybe a strain sensor?), DAQ and a laptop with right software.
Any suggestions?

pic16f84 simulation problem on proteus
Thanks. I highly appreciate your effort.
I'll investigate those samples you sent me. Great stuff. And maybe I can edit worktimer code and get it work with ISIS. Althoug it works with real PIC.
Thanks

pic16f84a lcd display .dsn
Hi,
I have a simple PIC16F84 LCD design which actually works with test board. I'm trying to get familiar with Proteus ISIS so I implemented the desing to it. The simulation seems to work (those blue and red dots are blinking) But I can't get anything to the LCD...
treadmill disconnects adsl
My wife was complainig that everytime I start to run on trademill - ADSL was disconnected. I verified that myself.
First I thought it's the noise the PWM motor derives to mains line. I could see some spikes with oscilloscope from 12V powersupply when running the...
I have a datalogger which logs simple voltage information to a txt file. I would like to see the graph on Excel. I'm using Data--->Import External Data--->Import data
then I choose my log file. So far so good, the data appears to excel. But how can I update it online? When I choose Refresh data...
AC current converter
I tried to use ICL7660 to provide -5V. But somehow I got only -2.8Volts with 5V Vcc. Why only -2.8V? And when connecting to LM324 it dropped to 0.52V? I had two chips to try and both acts similar way. It has only few external components, two 10uF caps. Why I can't drive...
AC current converter
Yep, this circuit works pretty well. I added one more opamp to compensate zero output 0.88V which I couldn't get rid of. . So I can raise the virtual ground level with 22k potresistor so that output reading is zero. But my datalogger has USB interface and I would like to...
I bought a 4 channel datalogger. Dataloggers inputs are DC voltage so I built an AC current to DC voltage converter using opamps, resistors and capacitors. I pick the current with inductive coil around main cable in .So far the circuit is not very accurate so maybe I need to try AD536 or...
