Exactly five months ago, on May 11th I received an e-mail from gflorez with a question:
"I must ask you, are you interested in doing a series of mouse adaptors?"
It's like waving a red rag in front of the bull's nose
By the way, my zodiac sign is Taurus.
Are you, gflorez, you're not accidentally toreador ?
From this e-mail began project EnterMice (name I came up a little later).
It was created from scratch.
Only on the basis of ideas and very detailed descriptions of the operation,
for which many thanks for gflorez.
There are a few of my original concepts.
Starting from the shape of the plate, joysticks matrix, circuit to generate interrupts,
ending on written from scratch firmware that supports PS/2 (maybe better than on PC
),
emulates a Neos/MSX mouse and a joystick.
A little statistics
The time spent on work on the project is 5 months on average approx. 1 hour per day
(not counting tests which has just officially start
).
This gives approx. 150 hours (times are approximate) at:
- project of the design (5h)
- electronic circuits design (25 h)
- project of PLD matrix (10 hours)
- simulations and tests of electronic circuits (10 hours)
- PCB design (20 hrs)
- execution of PCBs (48 h) - This part the Chinese did
- preparation of orders and deliveries of components (5 hours)
- preparation of components for assembly and assembly of interfaces (25 hours)
- preparation of software to test a prototype (5 h)
- tests of a prototype (5 hours)
- project of the firmware (10 hours)
- writing and testing the firmware (30 h).
Left to do:
- individual test of each interface
- shipping
Well, EnterMice is ready
First few pieces to tests will travel tomorrow to gflorez and Zozo.
After approval
will go to the other.
The final EnterMice price is 41 EUR (plus the cost of shipping within Europe 5 EUR).
This is the price only of components, PCBs and costs that I had to incur on purchases (shipping, duties, taxes).
The rest, all my work which is inserted in the project, you have free.
Perfectly wonderful time.
I wish you also have fun.
