More Maint and a teaser

Got an email from myself reminding me to renew my Let's Encrypt certs. Checking in here I found that auto renewal was failing cuz the renew utility needed port 443 in use by nginx. Stopped nginx ran the utility manually and, poof, all set for another 30 days or so.

Also I finally may have some content for this thing. I've been toying with FlashForth again and got hooked using it on a dsPIC33EP256MC502, really a sweet combo. I've been testing running some motors and generating servo pulses for a small biped that I've printed on my 3D printer. It got to be a hassle with all the wires trailing from the little bot to my dsPIC33E breadboard so I decided to tape up a small board using the PIC, a 5V @ 5A buck regulator, a 128x64 monochrome OLED display, 0.1in strip connections for 10 servos, 2ea. I2C off board connectors, off board connector for a USB to UART breakout, a RN42 bluetooth module with antenna, load indicator LED, a photo-resistor to measure ambient illumination, an off board connector for PICkit 3, power (switcher enable) switch, a reset pushbutton, and finally, two mini Omron pushbutton switches for user input.

Whew, when I say it all at once like that, it seems a lot. It might be but the board came out being pretty small at 2.25in x 1.6in or 57.15mm x 40.64mm. Major space savings was had using Micro JST-SH 1.0mm pitch off board connectors for most of the I/O. I've received (via ebay) a number of JST-SH 4pin and 6pin board mounted connectors with matching plugs with 4in leads pre-attached that I plan to use to hook up off board peripherals.

Boards should be here in a couple of weeks and I'll get to see if I my tremors allow me to still build SMD boards.
