hah I have the exact same super cheap multimeter, I feel better now (although it’s not the only one I have)

@dielectric:

Fella, don’t kid yourself. There are things you could try. Acid for his visual system, noise for his hearing. No matter what, he’ll always be one jump ahead of you!

You haven’t got a chance.

From datasheet (page 1):

Typical response time: 39 ms

Is the sensory really that slow or is that just the multimeter?

@edz: good to know about the jingling keys if I have to defend myself against killer robots. They usually have ultrasonics, right?

I think this kind of sensor need to be integrate to roomba washer / cleaner instead of hitting a wall and make very noisy sound for my neighbors.

Not quite as cheap as ultrasound proximity detectors can be, but far more reliable (jingling your keys will seriously screw with ultrasonic transducers).

I used one of these and hooked it up to the head of a Roboquad or whatever, took control the motors and used it to give an image of what the robot could ’see’, just converted it to analog and got the distance from the sensor to whatever the object was and moved the head in a grid like fashion to determine distance to objects between small degrees. I then sent the data back to my laptop and painted a grey-scale image of it. Only problem I had was since they were just normal DC motors the weight of the head after attachment with some brackets caused it to dip.

It was pretty snazzy.

When you test the analogue version could you please please test how far and close you can register hand movement. I’ve found with other devices that hands return only about half as much IR as the white paper the manufacturers use, so I’d like to know if this is similar, worse)

I’m planning a project using the analogue devices to detect hand wave gestures (three units placed in a line could detect wave right, wave left, wave top-left to bottom-right, middle stab etc!)

Many thanks as always for great parts write ups..

Neat stuff, thanks for the info and video.

Um wasn’t a device like this attached to a roland 808 type thingy and used like a theramin?

Wooa oo woo aa woooh!

Im sure i played with one in a mind altered state!

@cde

Interesting link. We also have the true analog version, we’ll demonstrate it soon.

I love these sensors but I have not purchased any yet since the cost seems much higher than it should be. I would like to see these come down to the $3 or $4 price point. Nice work on breaking it down Ian.
