Long time no see

I've not slept for 36 hours so this maybe a little incoherent. Since my last post I've completed the 3D Printer project. On a personal note it only cost me £50 to complete as I've an array of junk parts to source from. The stepper drivers amazingly were only £1 each the A2 stainless rods were $15.50 and the rest was for the extruder as I didn't fancy building that. One of the steppers is from a 1990 era dialysis machine and boasts 0.8 degrees a step. I'm overrunning these steppers to 200% for speed Vs. moving mass and they require heat sinks else they bind up and loose steps (yee-haw).

Secondly; I've made the smallest watch in my collection (32x32x7mm). It's only on the second prototype so it's a little junky-funk. expect some images to appear in a day or so. The third prototype will incorporate Blue-tooth (BLE) a nRF8001 chip from nordic. I'm still wrestling with the ACI (Application Command Interface) Thats has some silly features like command credits. my C++ Fu isn't strong so understanding some of the *euch* Arduino examples is tricky but getting there slowly. It's probably going to just have a UART link between the watch and phone with a custom app that bangs all the notifications to it.

Watches Watches Watches!

Watches Watches Watches!

I do love my watches. Lured a wonderful female into my life with one of these aluminium chunks of ..um art?


Binary LED watch

I made this using a PIC18F2550 (overkill) The readout is 0-9 hh:mm:ss for easy easy reading. It also scrolls swear words at ~10mph with persistence of vision. LEDs were taken from an alarm system. It sports a chunky mobile phone battery in the rear.









 SPI TFT Watch

My most complicated watch to date. PIC32MX250D with USB and MicroSD. Firmware update from USB or SD, needs lots of coding to make pretty and functional.





VFD Watch

A Russian IV-21 (NB-21) 1982? not looking very bright as the battery was low and there's no feedback for compensation. One of the first projects I did in KiCad





7-Segment watch

The thinnest of all my watches, the Li-Po battery goes in the front... yes, another bloody watch 




There's more somewhere
