Let's Make Robots!

Take that Apple!

After 5 stupid-ass denials, finally released a dead-simple serial terminal for iOS.  It neatly connects with an HM-10. :)

LPC1114 USB-Serial Solution -- Rerolling Boot Uploader

UPDATE: 6/04/14

Working UUE, but I know there are better ways to write it.  And I still need to deal with null padding.

Rerolled LPC1114 Bootloader Interface (v16)

 

UPDATE: 5/31/14

Been distracted by other projects.  Back at it.

I've a rough draft of the UUE encoder, but doesn't work.

555 Solar-Wind Controller -- For Ossipee

Ok.  I'm building a parts list for an SMD version of this guys 555 Charge Controller.  So far I've replaced,

Damage Assessment on the Kossel

Well, I ran into my first real fail of cheap parts.  Apparently the RAMPS 1.4 board I bought has two defective mosfets.  I'd like to take the blame and say I blew them, but I was being insanely careful.

And after inspecting the mosfets I've found physical damage to them.  Sigh.

Robot Contest up on Instructables :)

 

Question for Oss, Hoff, or someone with a 3D Printer

Alright, got my parts in for the Kossel, ran into a snag.

I don't suppose you think I could do something like this to fix it...

My Favorite Chip Sample!

I keep saying, I got into robots for the women...Max, back me up here. :)

Anyone else playing with LPC1114?

I know Mr. 6677 is playing with one off and on.  Anyone else?

I started using LPCExpresso, LPC1114_CodeBase, and FlashMagic.  Everything was going great until I found CodeBase is far from complete :(

 

Any suggestions?

Silas and SMD

So, someone was in my lab looking for batteries and knocked over my SMD passives container.  Luckly, the resistors didn't make it out, but all the 0603 green and yellow LEDs, along with a 3.3v SOT-23 regs were lost.

Sooooooo....guess who learned to use tweezers, how to identify LEDs, and what a "SOWT-TWENIE-DREE" was?

This kid,

 

Ok, shameless parent brag is over.

Yahmez' Y-Babies

UPDATE: 2/1/14

I'm about to send the first run of the ATtiny 84 version of the Y-Baby to OSHPark.  It is a lot larger than Yahmez' original design.  Coming in at 26mm in diameter.  This was necessary given it uses the LIR2032 and a SMD coin-cell holder.

A few design notes:
