**Ron Evans:** Daft Gopher. |
**Mat Ryer:** \[laughs\] |
**Ron Evans:** GopherPunk. |
**Mat Ryer:** Yeah. Yeah, they're just so great. And then there's lots of components and things for people to build... |
**Ron Evans:** Yes, we have fully assembled gopherbots for the people who want to explore the software side of hardware... And then we have all these IoT sensor kits, with individual sensors for people who actually want to touch metal. They want to plug in cables that control individual LEDs. We've got that for you as ... |
**Mat Ryer:** Yeah. As I'm talking, the robot's ears are flapping. |
**Ron Evans:** Yes, the ears move, they're on servos... That was one of the things people asked about the original tiny gopherbots, is "Do they move?" I'm like, "No, they don't move. It's an emotional support robot." You hold it close to you and you tell it what you need to tell it, and it just listens. It doesn't resp... |
**Mat Ryer:** \[laughs\] Yeah, nice. |
**Ron Evans:** But you know, for conejoninja, he really had to go to the next level... He had to go larger, first of all; full life-size. If you want to become one of the gopherbots, then... You know, it's got the cyberman style... |
**Mat Ryer:** You could get away with wearing them around Berlin, I think. |
**Ron Evans:** I think -- I saw someone wearing something very similar last night... |
**Mat Ryer:** Yeah... |
**Ron Evans:** But he's got these awesome TinyGo-controlled ears that have small servos... So eventually, we'll hook up a brain-computer interface and then they'll move based on your mood. |
**Mat Ryer:** Amazing. So how does it work in code then? Is there an API for these particular things? Do you send messages? What's the actual interface like for the programmer? |
**Ron Evans:** Well, it's all just Go code. And we do have APIs... We have a low-level API called the Machine Package, which in TinyGo lets you actually control the different individual LEDs at the very low level... |
**Mat Ryer:** Right. |
**Ron Evans:** And then we also have a drivers package, which has got somewhat higher-level, for things like displays, and sensors... If you wanna read the temperature of a particular known sensor, you don't wanna have to figure out the low-level protocol details. You just wanna read the temperature and then do somethi... |
**Mat Ryer:** I see. But that's cool that you still have the option of that really low-level stuff. That is very appealing, especially if you spend a lot of time in higher-level software. The fact that this also reaches out into the real world I think is really -- it gets really exciting. |
**Ron Evans:** And we have another layer on top of that, with some packages... There's a couple of packages specifically for displays, the TinyDraw and TinyFont packages. This is actually treating these LEDs on the helmet as if it was a kind of small display... |
**Mat Ryer:** Yeah, it's scrolling text, right? |
**Ron Evans:** ...and it's compatible with the same exact APIs as those little, tiny... These very, very small displays that are about the size of a postage stamp, and then you have these large displays and you could use the same types of software, and the same drivers, and the same TinyDraw and TinyFont package, regar... |
**Mat Ryer:** So how is the text scrolling then? Is that part of the driver tech, or is someone actually redrawing each time, and then coming up with the logic to toggle the LEDs individually, and stuff? |
**Ron Evans:** I don't know. But the programmer himself, conejoninja is right next to me and knows all the answers to these wonderful things. |
**Mat Ryer:** Well, that sounds like a great segue. Hey, how's it going? |
**conejoninja**: Fine, thank you. |
**Mat Ryer:** Yeah, so how does the text scroll on this display? Do you have to calculate what it's gonna be and then update things individually? |
**conejoninja**: No, we just have these fantastic libraries, TinyFont and TinyDraw. With TinyFont, you just say "I want to print this text, in this position." So we just move the X position... |
**Mat Ryer:** Ah, I see. Okay, so you have some kind of loop that you manage then, with a sleep in there, I assume, for the delay. So you're drawing it and offsetting it. That is very cool, because it looks very familiar. It just looks like a -- we're used to seeing this kind of scrolling text display, but you're contr... |
**conejoninja**: A couple of months... But I've been busy. |
**Mat Ryer:** Yeah. Well, I can see you've been busy. Are you worried about them coming to life? Have you thought about that? |
**conejoninja**: Yes. |
**Mat Ryer:** Yeah, a little bit... |
**conejoninja**: \[unintelligible 01:02:44.10\] |
**Mat Ryer:**Yeah, that's the plan, isn't it? \[laughs\] Well, this is it. I look forward to these. Because this is gonna be like The Terminator, but they're adorable... Yeah, so... In a way, be nice. |
**Ron Evans:** We're all gopherbots now. |
**Mat Ryer:** \[laughs\] Thank you very much. Great stuff. And if anyone's interested, check this out online, because the TinyGo project is really great. |
**Ron Evans:** TinyGo.org. |
**Mat Ryer:** Okay, there you go. |
**Jingle:** \[01:03:16.26\] |
**Mat Ryer:** Well, that's a wrap from GopherCon EU, and... I'm a little bit exhausted, but it was such a good -- I've met some amazing people, had some great conversations... I hosted with Ale, Natalie, Jessica and Vee. Co-hosting there was great fun. The Gophers Say podcast that we recorded live was great fun, and it... |
Great. Okay. Well, that's it from me, from Berlin, and from GopherCon EU. I had a great time. I'm off back to London now... \[wanker!\] You're welcome! |
