Thanks people I knew it would not be easy,
It’s more to find short circuits more than resistance so may be 500ohms may be ok, I’ll do some reading and testing and may be forget the protection side of things and make sure power is turned off
Thanks Dana some bed time reading looks a good book...
Sorry Yeah battery powered with internal power source (no common ground between meter and testing circuit) Like my fluke meter.
It will be working only on DC voltage circuit and 2 wires.
I know that the circuit should not be live while testing resistance but sometimes you may get a bit of...
Thanks but I don’t always have PC on site plus this could work expensive if you drop it , the remote display I use a Nokia lcd 100x100mm box with magnet for my voltmeter.
My idea is another device to measure ohms so the same display can be used for both
I'm looking at making a wireless resistance meter like my fluke233, But the trouble with the Fluke 233 meter the range is very short and intermittent dropping in/out.
I've made a wireless meter using an ESP32 using the esp-now protocol that can measure up to +/-100V DC only(that's all I need)...
Thanks guys,
The other system uses a similar type but this only has 4 wires 2 are the power supply of 12v feed both of the other wires give 2.5v out while in centre then when you push it forwards one increase’s to 4.98v and other decreases 0.5v, there is no markings or can’t find any data sheet...
Hi all,
I have a couple of these paddle joystick JC120-0002. It’s an Hall effect joystick that gives A voltage output of 2.50v in centre then down to 0.5v backwards and up to 4.98v pushed forwards from the wiper part and a switch type of thing (were you can use it to give direction of lever is...
I've looked through LEMO and BINDER manufacturers but can't see that type, these are fitted to plant machines and that's the trouble there is no marking or logo on them. The other side is jsut a round 7 pin where the one shown in the photo above just inter locks and you have to press the button...
I’ve got this connector and struggling to find it, Not sure who it made by or what you call it, I’ve been looking trying various methods but can’t seem to locate it or who sells it.
Any ideas would be helpful
Thanks
I borrowed a friend m a sealey power probe PP1 V3 and it looks like he has blown as there is no continuity between the terminals, It has got some markings on it, See photo attached.
The markings are TS-G24A and the small number is 19F28
I've tried searching but drawn blanks, I've been told that...
I had this issue, once you have created the gerber files don’t save them or export them. Then I use the original file to export drill file and save the drill file making sure the setting are set the same.
I found once you created your gerber files then saved them things mess up
No its pure DC voltage of 5V. It's just so that I can just use one transformer and rectifier smoothing capacitors to convert the 9VAC into 9VDC then regulator to 5VDC, Then one of the RI3-0505S to give me the 5VDC isolated supply
I'm currently working on a project where I need to have an 5V isolated supply from a single 5V supply.
I've been looking at these RI3-0505S Isolated Module DC DC Converter 1 Output 5V 600mA 4.5V - 5.5V Input rather than having 2 transformers/rectifiers to supply the 5V isolated power
I will...
Thanks for the input which is good to know.
How many SPI devices can I place on the SPI lines on an Arduino ?
I know each device has got to have it's own CS pin, Only I'm using to ST7920 128X65 LCD already, Just in the process of now adding the MCP4822 DAC'S to my existing code
I'm currently looking and working on project where I need run 2 X MCP4822 (12Bit Dac) and 2 X MCP3422 (16Bit ADC) but need to have them isolated as there will be 2 identical channels which all run from there own supply. The main unit that will be sending the data will be an ESP32 running from...
