SMD hand soldering is easy with solder paste!

You can even have success with 0603 and TQFP32 chips with a bit of care! After years of delaying attempts to try SMD soldering and then a couple of really bad attempts using traditional solder wire, now using solder paste I have confidently started soldering 0603 and TQFP32 SMD parts. After several successes, today I […]

Firsts: DirtyPCB, large design, Kicad use!

Ordered these prototypes from DirtyPCBs Friday morning, at factory Saturday, shipped Sunday, arrived Shanghai Wednesday morning (even with standard free post and parcel had obviosuly been opened at some point (customs?)). Looking good – only issues so far are my own design issues, like poor layout on this early prototype (taking advantage of up to […]

The Arduino F macro – saves SRAM and it is really great and nice and easy to use. It has been a real joy to use after struggling with the inter-related editing associated with use of PROGMEM arrays! However there is a big surprise for the unwary – like me. As you would expect, every […]

Telecine next steps, design decisions, camera & lense selection

          Thinking about next steps: 3D print and test the new rollers and capstans 3D designs … for example just realised capstan sprockets need to be rotated 90 degrees! Is there a need to improve camera, lense, or backlight before get into film cleaning, post processing and creating final movies Current […]

Telecine film or SMD roller openSCAD designs published.

Finally polished the code for the generic film & SMD tape rollers, including updates to use thingivers customizer, so users can adjust parameters in thingverse. openSCAD code is available direct in thingiverse and via the customizer and also on github. Design is yet still unverified, hopefully will try some 3D prints in next week and […]

Film or SMD feed roller - capstan 8mm/16mm/35mm...

Designing a combination roller/capstan for the telecine prototype as the mounting of current sprocket has some wobble in the mounting. Also need at least one more roller to improve film tension and frame position stability/accuracy. Plus looking to use for SMD, 8mm and 35mm films, so have been making the scripts very easy to change […]

The telecine code has been opensourced here. (Edit – updated URL) Readme extract: MovieFeedControl Summary: This code controls two stepper motors for film feed and take-off. Sendkeys is used to send keystrokes to computer application to trigger frame capture via chosen camera – application. So you need an Arduino Leonardo or Teensy. Currently only tested […]

There is plenty of good information about the web and several summaries of telecine methods, but I still struggled to choose the best approach that suited my goals. Partly as I need hands on to better understand things and partly as different summaries were incomplete, in conflict, or out of date. So hopefully this summary […]

Telecine simple, cheap prototype in action.

Simple(ish) telecine prototype that has very flexible construction options. Below is the prototype in action converting a film. Sorry about the clutter, will post some build photos that are a bit clearer in next posts. It is cheap … depending on parts you have. I had steppers, projector, case, power supply and a film scanner […]

First projects using new 'pimped out' personal hackerkspace

The layout and organisation of what goes where is evolving, but is already proving pretty good! Just won an auction for about 35 square meters of 30mm thick particle board ~700kg!. So now can do a full renovation (walls, ceiling and storage) on my machine room (garage) after another auction win (~700kg of 30mm particle […]
