Pixel Versions of the LMR LogoBot

A while back I drew up a 32x32 px version of the LogoBot, but I don't have a 32x32 LED matrix to display it on. I do have a 16x24 matrix that is collecting dust though. I decided I'd try and make a 16x16 px version... here are the results. You cannot upload .bmp files to LMR so if you intend to use these you will need to convert / save as .bmp format. If you end up using one of these and take a photo, could you post it here? I'd love to see this on some different displays.

Looking for RoboVoice IC

I have been looking for a RoboVoice text to speech IC and it seems they don't sell them anymore.

I'm posting here to see if anyone has an extra one on hand that they are willing to part with? I'm willing to pay or barter for it.

What does this circuit do?

Found this today... I'm trying to figure out what it does. Any guesses?

Support PopPet

Update,

Looks like dx, banggood and tindie all pulled this from their 'shelves'. Banggood wants to know who can supply PopPet. I'm passing them CP's way.

I'm scrubbing this post to avoid giving anyone bad names at this point. Thanks everyone.

Hello Guys & Gals,

I am posting this so that fellow LMR members know what is going on, and send an E-mail to ____ in support of PopPet.

Heated Bed Warning Light

Hello everyone, I thought I'd share a circuit I am using on a little 3D printer upgrade project.

I have a heated bed PCB for my Printrbot that I am currently adding to the underside my aluminum bed. I needed clips to hold the pcb in place and provide a housing for wire strain relief. I designed some and printed them out. I wanted to add LED warning lights to the clips so they would glow when the bed was hot. I really wanted the lights to stay lit after the bed was off and slowly dim to nothing over about an hours time like the warning light on my stove does.
