Any FIRST Robotics team mentors?

My younger son has joined his high school Robotics team to compete in the FIRST Robotics competition (website) . The students build fairly sophisticated tele-operated robots to compete in an invented arena. Each year is different; last year was a basketball gathering + shooting game. The student tea...

Bring out your GIFs - signboard going to production

The glass block sign board is going in; we've got 1 panel in now, and we should have 3 live by Monday. They look great, and we'll have a great sign facing East. So once it's ready, we'll have a signboard app to put any text we like, and most importantly, a tetris app. But we'll also have a 'display ...

Favor: update MAC address for LED system?

A while ago, someone (David?) very helpfully set up the dhcp server to assign my old laptop to a static IP and the host name of led.tcmaker.org. I was hoping to update that information to use the MAC address of b8:27:eb:7b:5f:95; that corresponds to the new Raspberry Pi I've dropped in to drive the ...

Re: LED sign board update

Okay, the Raspberry Pi came in...and sat. But I finally got off my duff and installed it into a control box, and largely un jury rigged things. Now they're just rigged, I figure :-/. So, I think we're ready to go to production. I've updated the task list on the Wiki: http://www.tcmaker.org/wiki/doku...

Re: LED sign board update

For those of you who missed it, we had the boards up and playing Tetris during Minne-Faire. Things were still a bit jury rigged then, but the core vision was realized. And today today I got to place my order for a Raspberry Pi. So, in theory, in just 6 short weeks I'll have what I crave to finalize ...

Re: Glass block lights update

Pete, I came in last night and tacked down one of the strings you soldered up (thank you very much), and made sure that the 4th connector you set up worked as well. So I think the todo list is as follows: For step 1 (a 10x20 grid in the current West window) Drill the last board we have, and put in t...

Re: Glass block lights update

Okay, I think I've done most of my awful electrical hacking and can get back to the software. Electronics gurus are welcome to go and clean it up, so long as you leave it operational. The lights should be pretty much operational. Nicely, switching the PC power supply on/off is an easy way to turn th...

Re: Glass block lights update

Alright, trailer hitches work great, and it looks like a PC power supply will work fine as well. Sadly, I learned that running negative voltage into a string of lights seems to kill 'em. Hopefully, I've only killed the first light in the chain and not the whole string. So I think that counts as 3 st...
