Camera and Lens testing
Log from Portable Video Microscope
Digging out the various camera's and lenses I had, I set about testing different combinations. I was testing for zoom range and the minimum and maximum focus distance. Some of the options would require making a custom mount to connect the camera to the...

The rig works and I flew all sorts of missions
Log from Your Personal Flight Simulator
I configured this beast with everything I had and kept tweaking it until I had a working system. And of course, it works and works well. But it's mounted to my desk....As you can see I have yolk, pedals, single engine throttle quadrant, a 6-pack, radio,...

FTF = File To Fit. Yeah, V1.0 of everything seems to have problems. :) Anyway, good news. The beast is up and running with the Frankencarriage install - after extensive fiddling and cracking and patching and filing.Here are some...

Carry and borrow
Log from PDP - Processor Design Principles
If there is anything that fueled the RISC vs CISC debates over the decades, it's the status flags, and among them, the carry flag is an even hotter topic. This flag has been a common feature of most architectures and MIPS slashed it. Considering that...

Where does the speaker go?
Log from FATCAT: Altoids Tin Mod Tracker
For sound output, I initially designed FATCAT with a small PCB mounted piezo speaker in mind. While that's still an option I've found it difficult to source piezos of that size that can achieve high enough sound volume. I've had some luck with piezos...

New Feature: One Button Record and Stop
Log from Raspberry Camcorder and Video Editing Station
I decided it was time to finally start cleaning up my code this morning, and it's going surprisingly well. I created some basic functions, and basically started over. I finally got a function working that lets me start and stop recording by pressing...

Milling Videos
Log from Shoptask 1720 LinuxCNC
Some peck drilling in 1080, and keyway cutting in W1 tool steel. This is all handwritten g-code. I find for these kind of operations it's easier to tune this to the machine than working through the Fusion360 CAM. The keyway cutting video quality is crappy...

The board material list
Log from How to use an aerial 36 inches lens
The 5 mm thick L profiles have been roughly cut to fit the circular shape, they already had exactly the good length. 2 holes that hold the lens are going to pass thru the 3 mm board and the 5 mm L profile on each side, 8 mm thickness should be...

TKIRV - now controllable over the internet! Because hell yes. Check out the orange wheeled monster in action...From the beginning, the goal of this project has been to build an R/C car that can travel far and wide. This necessitated a way of controlling...

Starting Software Development Back Up
Log from Raspberry Camcorder and Video Editing Station
The first version of the code I posted is very crude and often errors out. It keeps saying there is no video recording when you go to stop the video. It only does this sometimes, not consistently. As I type this, I suspect that the "if" statement that...

Transputers?
Log from Keplermatik
At some point in planning this project, I stubbornly declared to nobody in particular that the hardware in question had to be era-appropriate and suitably exotic. Preferably something used in spaceflight. Something not commonly found in home or business...

Centripetal Force and the BLDC Gyrofan
Log from TrillSat
I started to look more closely at the centripetal force equation, since I've been wary of raising the Gyrofan speed higher with its full mass, as I didn't know exactly how much force was being generated. I'd like to ramp the thing up to get appreciable...

[E1][T] Photon M3 Screen
Log from SecSavr Suspense [gd0105]
So I'm browsing AliExpress and stumble upon the control board for the Photon M3. Additionally, the Photon M3 screen was still available for the £54 price, and with more quanitities than 1 or 2. So I start thinking of what could have been when...
