This reminds me of the Atari 8 bit computers making sound when data was being transferred to the floppy drive and the cassette. The TRS-80 flashed an asterisk in the upper right corner of the display. I wish this was an option with modern c

An item the analysis didn't include is using Starlink signals for location, posture, and rotation. I have no idea if they do... Love the analysis.

Nice! I'd like to generate a Chebyshev approximation for a set of X, Y sensor values. Any hints on how to modify your code to do that?

I'm a very long time Windows user and am very very frustrated with Microsoft's shenanigans in the last few releases of Windows. I'm contemplating trying Linux but: 1. I don't know which distribution to start with. 2. I

I wonder if without the RISC-V cores the design was pad limited i.e. it had due area that wasn't used. So, they put in the RISC-V cores for no die cost. There will be some cost to test the RISC-V cores.

Thank you for doing this. I'd like to do the same. Any suggestions for getting started?

In many areas, the notion of government services operating at a loss doesn't make sense - police, fire department, armed forces, libraries, parks, etc.

Thank you both!

Unbelievable! I'd be very grateful for an explanation for how the first three lines in the Atari basic version that have only numbers and no alphabet work? I just can't remember what Atari basic does, how that data is presented to

The balls are missing to enable making connections to inner balls in a board with fewer layers. The outer balls take up space and so block the traces from inner balls. By strategically removing some of the outer balls, you create channels t

From your writing it is clear that you think very clearly and have good awareness. I hope you succeed in finding a place where others compliment you, and you them and are in a team with a lead who supports you. I've been in, asked let

In the Arthur and DW ActiMates ( https://news.ycombinator.com/item?id=36656190 ), my teammate, Craig Ranta, implemented the Real Time Clock using a Microchip 12C508 or 12C509. It ran at 32.768 kHz. Using the microcontroller w

I really hope you take a look at the 68000. I'm curious how Motorola's circuit design and approach differs from Intel's.

This. The voice chip on the ActiMates was a derivative of the TI Speak-n-Spell chip.

Not Barney. In Arthur and DW, on my birthday, of you press the correct sensor sequence, they will sing me happy birthday. On Teletubbies, there is an Easter egg that I think scrolls the developers names but it has been too long i.e. I know

Good job finding it. The patient calls out two other key patents. It also describes how the data is encoded.

by Zeetah 3y ago
The data was encoded of the left side of the picture. I believe there is a patent on this. My friend, Leonardo Del Castillo invented and productized this. So, look for his name. He was the electrical engineer lead.

Wow! Nice trip down memory lane. I was one of the three Electrical engineers on Barney (and the ActiMates product line). The three of us divided up the system design, radio and radio protocol design, PCB layout, and a bunch of other items.

Many of us have tried A* but because the maze is so "small" (16x16 or 32x32), the "just solve it every time" using Dijkstra's or a flood fill or similar algorithm wins out. In particular, in A*, the "to be expl

LOVE THE ENTHUSIASM! I hope you all will make some mice. I'll watch this thread for more questions.

I did not. Funny story - I was in college and the IEEE chapter was having a meeting with free pizza. I went to the meeting but went into the wrong room and in that room they were having the Robotics club meeting. I was intrigued enough to s

This eventually evolves into a controls problem i.e. reading the sensors and then driving the motors and keeping the mouse in control. With the use of a fan, the limit is now how much down force can you generate and then can you drive the w

I use C. I write all the code from bare metal i.e. no OS and I write my own routines to initialize and use the hardware. I could use the routines that the MCU manufacturer provides but when I've tried, I've found that I spend a la
