Nice, love the history lessons and seeing the LM232. do you have a component break down of the board maybe a schematic. What bluetooth module did you use, is the microcontroller an 18F4455 ?

Yeah that lm232 was a great find for that board. The v3 eventually used a heat sinked 5 amp regulator, that was way more efficient

I forget the micro. It was a 18f465 I believe? At 40mhz with pll

The 2.1 was a prototype to see if there was an addressable market interested in this sort of modular robot platform. I soldered them in my basement haha. It was a fun time!

nope, i have an ez-b v3 4 and an iotiny

DJ I dont think i have ever seen one but i do remember way back on youtube when you first started showing how you could make it more easy to hack the robosapiens.That was when I had my v2 looking to find hacks.Of course back then i thought you just had a temporary business idea that would go nowhere. Wow was i ever wrong about that LoL!

Thanks RoboRad It's been a fun and long adventure - that's for sure! A lot of other robot companies have come and gone in the time we've been progressing.

I still want to get my hands on one someday.

Ha you're really digging up old good stuff. It's funny the photo of the v2.1 is not even there. I don't know if i have a 2.1. I think i do i a box somewhere but not sure where. I hand-built the 2.1's myself. I'm not sure how many were sold before the v3 was released.

I remember before the current EZ-B camera was used, you used to use a wireless webcam. The downside was that you would have to charge it. However, you took it's charging cable, cut off the unnecessary wires and soldered the power and ground wires to an EZ-B cable and you were able to get power to the webcam from the EZ-B. Now, this process is no longer necessary because of the new camera not being wireless. However, this was helpful before the EZ-B was given a dedicated camera port.

Remember the videos where people would make battery operated toys go over the original voltage? Almost the same process except it's directly connected to a power supply.

Speaking of old EZ-Robot products, were any robots shipped with the wireless webcams?

The robot kits for the ezb v3 all had the wireless camera. There were thousands of those shipped, yeah. Not sure how many have survived on peoples robots. I still have all my old robots, even the ones with v3's and the wireless camera.

I meant revolution robots like JD, Roli, and Six. I'm sorry for the confusion.

Oh, no. The EZB v4 included the camera connection by that time. The v4 was developed in conjunction with the revolution robots.

The reason why I was asking was because in promotional trailers for the revolution, the webcams were shown instead of the (better) wired cameras. The webcams could have been used as placeholder.

It is a 2.1 and they still have it
