10:02:43 From James Newton To Everyone:
Looking forward to it. The history of software development is a long time interest.
10:02:56 From James Newton To Everyone: See what I did there?
10:03:11 From James Newton To Everyone: Nice! Does my heart good!
10:11:07 From Ihler To Everyone: SRS PopCan Challenge in Feb 24th.
10:29:13 From James Newton To Everyone: I strongly recommend this Youtube video
10:32:47 From James Newton To Everyone: Interesting approach to a working robot:
10:33:41 From James Newton To Everyone: Disney walking robots. Cute
10:34:31 From James Newton To Everyone: turtlebot
10:37:58 From James Newton To Everyone:
Using ChatGPT to control a robot by asking it to write a program with custom actions:
10:39:03 From Ihler To Everyone: 350W driver for “hoverboard” motors: https://www.amazon.com/gp/product/B087M2378D/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1
10:41:26 From Colin L To Everyone:
There was no cement holding those bricks together, apparently. Or am I wrong?
10:45:48 From Colin L To Everyone: Reacted to “There was no cement …” with 🧐
10:45:54 From James Newton To Everyone:
@Colin L they do use cement normally, as far as I know. Might have been a practice run?
10:45:54 From James Newton To Everyone:

10:47:14 From Colin L To Everyone: Probably so.
10:58:57 From Colin L To Everyone: I knew things were probably going where Slaughterbots was going, James.
11:00:32 From Lloyd Moore To Everyone: https://nwcpp.org
11:05:05 From James Newton To Everyone: The linker invited by “Amazing” Grace Hopper, BTW.
11:13:26 From James Newton To Everyone:
It’s really good to have data transmitted instead of stored when your prototype might explode aka rockets.
11:13:52 From Colin L To Everyone: Reacted to “It’s really good to …” with 😂
11:18:46 From James Newton To Everyone: Silab is also a good name. CP21xx line.
11:21:02 From James Newton To Everyone:
You can get better range at high speed with twisted pair, and actually following the RS232 standard (which is the signaling standard, not the UART standard).
11:22:13 From Ihler To Everyone:
We run RS485 at work for some older tech up to 5000 ft but at lower speeds (38400).
11:26:57 From James Newton To Everyone: Gotta love the blinky light. It’s a great starting point and fall back.
11:28:09 From James Newton To Everyone:
Blinking out an error code is a great backup for a product as well. Just have the customer send you a video and the extra bit of data can tell you a lot.
11:28:30 From James Newton To Everyone:
Great to use it as a trigger for scope or whatever.
11:32:34 From Ihler To Everyone:
Logic analyzers are great tools for troubleshooting bare metal applications (and blink-error codes).. you can get them anywhere from $15 to .. well the sky is the limit. The $15 LAs are okay enough to get along but I recommend something that plugs into your USB port, has some kind of computer based app and has a protocol analyzer that includes types of communications that you want to use (UART, I2C, etc..). I have a Saleae LA that I love and can’t recommend enough.
11:34:00 From James Newton To Everyone:
Love my Lab Nation SmartScope (also an LA and waveform / signal generator, and protocol analyzer with open source plugins). The best part is the user interface with super easy operation.
11:35:57 From James Newton To Everyone: The first job of a programmer is to NOT write programs.
11:36:43 From Tony To Everyone: Replying to “The first job of a p…” Oh but where’s the fun in that lol.
11:38:12 From James Newton To Everyone: Reacted to “Oh but where’s the…” with 😂
11:39:23 From James Newton To Everyone: The Power of Compile Time Resources
11:39:43 From James Newton To Everyone: Javascript’s JIT compile is sort of an example of this.
11:40:50 From James Newton To Everyone: Well, you can patch a single file program.
11:42:40 From James Newton To Everyone: Animated simulation of CARDIAC:

11:43:20 From James Newton To Everyone: NAND Game is also very very good for learning
12:00:05 From James Newton To Everyone: Great presentation Lloyd!
