Optical mouse for Amiga classic

[aGGreSSor]

I adapted modern optical mouse for standard Amiga port.  The author of this idea StarCat from amiga.org.ru forum. He described it verbally, but I decided to solder in reality. The advantages of optics to mechanics obvious. It doesn't require any adapter, plug'n'play

You can watch a short video on You Tube (including English subtitles).

If you are (non)interested in this topic - let me know.

Interested in making some money? I'd like one. Make it for me and name a price.

Interested, but not this time. Modification is extremely easy.
You don't need programming PIC. Only required accuracy.

Amazing!

I'm photographed the entire process and will describe it "step-by-step" in his blog.
My article is written in Russian language. I didn't know how to write in English.
It gives me great difficulty. At the same time I'm well read English texts.

I would like to find someone who would be able to translate into English and publish
this simple thing for everyone. This may be material for amazing Amiga magazine. =)

I remember an Amiga optical mouse back in 91 that needed a special mouse pad with a grid pattern to work.

I like mouse pads, but for this mouse doesn't need.

Well, you can only convert a couple of older optical mice with a sensor chip that has quadrature output pins. There are a couple of older Logitech mice for which this works. Basically, one has to remove the microcontroller and connect the quadrature pins of the sensor chip directly with the Amiga mice.

Yes, I've done this a while ago with an old Logitech mouse, works fine given that you have the right type of vintage mouse.

You are absolutely right. But I never read about it.
It works on a large number of mouses. It's necessary to specifically look for the mouse with the right sensors. For example PAW3602DH, PAN3201H, etc

quadrature pins of the sensor chip directly with the Amiga mice.

I read your link. I think so, no one working? This is possible, but it is wrong. It should look a bit different.

Sure. But if you just buy an average optical mouse today, it comes with an all-integrated sensor chip that includes the USB interface.

Most of today are designed such mice. I'm redid Logitech M-BJ58 with USB interface (2008 year). Logitech M-BJ69 (2012 year) also nice. I'm even find them on sale, not only in museums. :lol:

Only older models used two separate chips, which is a more expensive design and is nowadays no more available due to its cost factor.

Of course I am always inclined to plunder museums. In fact, the sensor is licensed "know-how". His only produced in different versions, with different power and strapping. The same sensor can be operated with different 400-2000 cpi. Artificial lock. Some sensors have a CPI pin for select. Often in a mouse for gamers and office is the same sensor .. =)

Thus, if you find a probably ten year old mouse in your house (an electronic one, not the biological cheese-loving creatures), chances are quite good. Everything younger uses likely a single-chip design that is unsuitable for a modification.

 The Chinese produce sensors including quadrature outputs. I bought a USB-mouse year ago in Finland, some Trustex and found in it a chip HM-bla-bla with quadrature outputs. They do it. The presence of the interface chip allows use USB -> PS/2 adapter. It's more compatible mouse. There is no guarantee that chinese sensor will approach us. Required a list of compatibility.

I hope this is not too far off topic.
Do track-balls still exist for the Amiga?

The Kensington Optical Expert Mouse (trackballs) previously used an ADNS-2051 optical sensor. Possible use now. Produced today and modified with the topic equally. Therefore Amiga have them.

the printed circuits looks terribly and it is next to impossible find out thin and flexible rounded cable, but the mouses work perfectly.

When finished creating a layer of wires (remember about clearance = 2.1 mm!) also visited the idea own mouse PCB... Now I see that there are three ways:

• Direct connection of the sensor to Amiga mouse port. (conditionally, deutsch version)
• Almost the same, but with harmonization (russian version)
• Wiring own board (czech version).

Surprisingly, when people didn't know each other come to the same in different ways. Thank you for your reference!

It is really a matter of the chip. For the mice I had a look at - the old version - the chips were designed for TTL logic levels in mind anyhow, so the quadrature output can be connected to the Amiga TTL input directly. This is not necessarily true for all chips, some use an internal conversion to 3.3V and run on 3.3V logic levels.

Absolutely.

I personally tried to recycle as many components as possible, so the mouse itself is the original Logitech design, the mouse cable comes from a defunct Amiga mouse and hence fits nicely. The drawback is that it lacks a wire for the middle mouse button.

This is a very big problem. I used twisted pair like UTP Cat5e and it isn't sufficiently flexible. Inelastic telephone cable like 01-5402 REXANT (10 wire) too bad. Multi-colored plume is more flexible, but also no good. It's problem.

The czech version is a new "design from scratch". That's of course the better solution for professional vendors, but not an option for hobbyists like me.

It's completely amateur, Toner Transfer Method. It depends on the willingness to bother. Personally, I'm just lazy.

In the beginning of the topic was promised a big russian article. I'm fulfilling my promise!

Perhaps it can be read in google translate.

:hammer:

I did the same thing with the 800dpi genius optical mouse only i installed the pic in the DE9 housing, so its all self contained and no adapters needed, i used the project on aminet to program the pic chip.

It's an excellent solution. Thanks to RDC, we have it in various realizations (including industrial). But PIC scheme requires more experience and more expensive. Support mouse at the same level (PS/2 and Combo).
