Vacation over, new boards on the way

The project moves forward. For the last couple of months we’ve kept busy finalizing the design of the instrument, trying to minimize noise and pickup of unwanted signals. We currently have two sets of boards being manufactured, which should hopefully arrive fully assembled in about a month. We’ve also had a much-needed vacation right in the middle of the current heat wave 😅

One of the boards currently being manufactured. Rendered via KiCAD.

Next up is providing more accurate mass, center-of-mass and moment of inertia measurements to PTScientists. We’re also working on finalizing the data format, since that decides how much bandwidth we need. So far it’s looking like around 200 B/s while the instrument is running. We can probably cut that down with some compression, at the cost of increased latency. Possibly more on that in a future post.

Vacuum setup

Just some pictures of the vacuum test setup which our MSc student has built.

The stainless steel mesh allows us to apply some known static electric fields to calibrate and evaluate the performance of our instrument.

God Jul! Merry Christmas!

Ytterligare ett år håller på att lida mot sitt slut, och vilket år det har varit! Vi har hunnit med massor av roliga saker och träffat intressanta personer.

Vi har bland annat träffat forskare och ingenjörer vid IRF i Kiruna. Vi har under våren arbetat intensivt mot satta deadlines för att se om vår “organisation” kan leverera under stor tidspress, det kan vi! Och nu under december månad fick vi möjligheten att hjälpa till i Musikhjälpens årliga insamling som i år samlade in 74 miljoner!!! till arbeten för att motverka barnsexhandel. Vår egen auktion drog in över 30 000 kr!

Nu ser teamet fram emot en välförtjänt semester över julhelgen och nyår.

Vi ses i januari!

God Jul och ett Gott Nytt År!

 

//Yet another year is looming to its end, and what a year it has been! We have had tons of fun and meet amazing people.

We have, as an example, meet up with scientists and engineers at IRF in Kiruna. During the spring we stress tested our organization and worked towards strict deadlines to see if we can deliver top quality under heavy time-press, and we did! We have also been helping Musikhjälpen with there annual fundraising. This years theme was to raise awareness and money to battle child trafficking. The total amount of donations accumulated to 74 million sek! And our own auction helped raise over 30 000 sek!

The team is now looking forward to an well deserved vacation and we will be back in full swing in January.

Merry Christmas and a Happy New Year!//

Här är ett urklipp från Musikhjälpen 2017 då vi gästade glasburen (det är på svenska).

Vi medverkar i Musikhjälpen 2017!

Thumb_Lunar

Likt förra året så medverkar vi i Musikhjälpen 2017! Till förmån för utsatta barn så auktionerar vi ut en möjlighet att få ett meddelande inetsat på ett kretskort i vårat instrument, som är tänkt att landa på månens yta! Gå in och buda på Tradera-auktionen genom att klicka på denna länk.

Vi kommer även att medverka i själva programmet Musikhjälpen klockan ett imorgon kväll dvs Fredag kväll dvs Lördag morgon 01:00. Vi kommer att berätta om vårat projekt samt såklart uppmuntra fler att gå in och buda på auktionen 🙂

Vi höres då!

Work continues

It has been a hectic autumn with little time for updates, about time for one!

First of all we paid IRF a second visit, for vibration testing. This turned up one problem, an M4 nut coming slightly lose. To rectify this we’ve invested in torque wrenches and are working on an assembly manual with specified torques for every screw and nut. For the curious, the work-in-progress manual is up on our GitHub account here.

The second bit of news is that we have a master’s thesis student working with us, Clayton Forssén. His job at the moment is to write LabView code parsing output from our prototype instrument. The goal is to get a series of measurements done in our vacuum chamber with the new XYZ E-field applicating cube (a miniaturization of the capacitor plate plywood cube we have used in earlier tests).

The third news is that our deadline has been pushed at least another year into the future. This gives us some much-needed time to fine-tune the design, code, documentation and so on.

That’s all for this update. As always, keep watching this space for more interesting stuff 😎
