This pictue show the error in micros stepping on my lineair stage. I use 8 micro steps for 1 full step on the encoder. 1 full step = 1um. The speed is 4000 micro steps/sec. As you can see the total time of the micro steps is not equal but the sequence is repeated after 4 full steps (not to see here due to the limiet of the picture but on the logic analyser the cycle is repeated).
This teeny tiny swoon block finishes at 2" square - which means the HSTs finish at 1/4"!! I set it on point inside a thing pink border and matchstick quilted it with some variegated thread.

Exposition
VERNISSAGE PUBLIC : MER 21 MAI - 18:00
L’infini n’a de cesse de nous fasciner, qu’il soit petit ou grand. Ses représentations comme ses perceptions ont été dernièrement bouleversées par le numérique.
Les données d’aujourd’hui sont reproductibles sans limite et la miniaturisation des processeurs augmente en permanence nos capacités. En conséquence, notre appréhension du monde augmentée remet perpétuellement en jeu les échelles. On s’est tous habitué à se propulser au sein de vues satellites et à parcourir le globe virtuellement en quelques clics jusqu’à l’inexploré...
Les progrès scientifiques, en accélération comme toute la société, bénéficient des effets de la circulation instantanée des données et de capacités de calculs toujours plus puissants. Le web accueille de nouveaux micro-processeurs connectés à chaque instant et donne accès à un champ lui aussi en croissance permanente.
En quelques années de nouveaux infinis sont apparus et sont eux-même pris dans une expansion incontrôlable. L’exposition Micro Macro s’intéresse à ces phénomènes contemporains, au travers d’un parcours d’œuvres d’artistes internationaux.

Tiny micro-droplets of water sticking to this stem. Was probably remnants of the first major frost of the year.

Over the last 40 years, TWI has been at the forefront of the research, development and application of many non-destructive testing (NDT) technologies. The driving force behind these developments has been industry's need for techniques that would accurately locate, characterise and size flaws in every type of component and structure, from printed circuit boards to offshore platforms and from medical implants to nuclear reactor pressure vessels.

55mm f2.8 micro nikkor AI-s-manual "1981 model"
after fidling for much time i end up with a decent light setup,,exprementing with product photography,,this old micro nikkor is gem ' 55mm manual,no metering or any auto functions work with d70 body but very easy to use if you already using the manual mode for years.. ,high optical quality compared to now a days lenses.,i think its outa production since long now, ,,,
Sorry It's only a screen shot Bluerender doesn't seem to recognize the colour and renders it a dark Gunmetalish shade
This was one of the smallest Classic Space sets ever made, and was not available in the US. Building the tiny sets presents a unique challenge, as it's hard to get much detail without bulking up the model too much. The rear of this craft had an anomaly: transparent blue used for the engines. This color was not used in Classic Space until 1981 when it was paired with white vehicles.
