Thingiverse - Newest Derivatives

RS232 add-on for the badBrick model B RaspberryPi case


This snaps on top of the badBrick model B RaspberryPi case to hold a level-converter for RS232 so the 9-pin D connector can be securely held to the RaspberryPi for easy connection and disconnection. This makes the RaspberryPi significantly more useful as a micro-computer for dedicated devices (I use one for interfacing to a Amateur Radio transceiver via the UART serial built into the RaspberryPi and a USB sound-card)
NOTE: this is the serial adapter that I designed this to fit.

That particular adapter is more expensive but works "out of the box" for not only TX/RX but also CTS/RTS pins which my project required.
These CTS/RTS GPIO pins can be enabled with a bit of soldering and programming, details found here: dl8scu.wordpress.com/tag/raspberry/

Medieval Double Window for Block City blocks


Because sometimes a tripe wide window is overdoing things. This window is two blocks wide.

Geomagic Design - Mesh to Solid suddenly missing


Update: FOUND IT!  You can scan meshes in the parts and the assembly editor but only in the parts editor are the other tools visible. Very confusing UI inconsistency. There's no reason this wouldn't just create a new solid part in the assembly editor.


My Geomagic Design suddenly decided to no longer allow me to convert Meshed to Solids.

That's the sole reason I purchased the last update.
I had positive email confirmation that the features would be in there (they where not on the website then, only in the promotional video for the new version) and based on that information I shelled out the money for the extended support contract that would give me that update.

My license states "Geomagic Design".
(Not "Geomagic Elements")
The website states that this feature is included in Geomagic Design.
I still used that feature extensively in May after having extended the support contract in March.
Now in October this most important feature is suddenly gone.

printfs syscall in ARM assembly

You can assemble and link it with

arm-linux-gnueabi-gcc --static hello.S -o hello
.data
LC0:
	.ascii  "%d\n"
.text
.align  2
 
.globl main
main:
	stmfd	sp!, {r0, r1, r2, r3, r4, r5, r6, lr}	@ save the registers we use to the stack
	movs	r4, $0
loop:
	ldr     r3, L3
	movs	r0, r3
	movs	r1, r4
	bl	printf
 
	adds	r4, r4,$1
	cmp	r4, $100
	bne	loop
 
exit:
	ldmfd	sp!, {r0, r1, r2, r3, r4, r5, r6, pc}	@ restore registers before exit
	movs	r7, $1                  @ set r7 to 1 - the syscall for exit
	swi	0                       @ then invoke the syscall from linux
 
L3:
	.word	LC0
	.size	main, .-main
