- In my opinion as a student with engineering background there was too much focus on the design and creative part of the discipline, rather than on the technologies and devices used throughout the course. The good part was that seeing many phycomp projects gave me a concrete idea of what the discipline is about.» (2 (low))
- Most lectures just listed and showed a lot of projects other ppl have done. It would have been very very useful to have some kind of introduction to electronics, soldering quality, etc, etc.» (2 (low))
- Not very interesting content. It felt as though the lectures was just another place and time to showcase some stuff that people have done in the physical computing field. I would have appreciated more depth and analysis.» (2 (low))
- Good: Links about where to find information was given Bad: Most of the projects showed in the lectures were arty stuf without practical usage and some just useless. It would have been more intresting if some with practicl usage was considered too. » (2 (low))
- The rooms where the lectures was located was way too small and it got very warm in the room which makes people tired. » (2 (low))
- Too basic content, based on my previous background (3 years bachelor so nothing special)» (2 (low))
- More relvant lectures towards what we do in the labs» (3 (average))
- For many of us have no ideas when we first contact with some components and circuit, although we read material book, there need more interpretation.» (3 (average))
- having resource is good, but it is better to have more lecture.» (3 (average))
- Overall, the course could benefit from having less examples, more detailed perhaps.» (4 (good))
- Great course structure, smart choice of using a blog for home assignments, » (5 (very good))

- Too difficult, given it"s intended for beginners also. the first exercise should have been second (after we learn how to solder and layout, and after a smaller example on breadboard)» (1 (very low))
- WAY to advanced taking into account the general electronics skill level. No decent soldering course AT ALL, no general electronics introduction etc, etc.» (1 (very low))
- Most student don"t have background, but made soldering and operate an IC in just first course.» (1 (very low))
- Since I already had the knowlige about this it didn"t give anything to me. But I can understand it"s good if you have another background.» (2 (low))
- it seemed too complicated for a first lab assignment» (3 (average))
- Good: hands on approach on soldering and physically building of circuits. Bad: probably a little bit too much complex for a first lab.» (3 (average))
- For me who know how to solder it was kind of wast of time, but i understand the need of teaching such skills to the participants in the cource. Improvement: Setting up a more advanced alternative for the people who already know » (3 (average))
- I missed the first of the two days that covered lab 1. But it was alright.» (4 (good))

- This lab was very unorganized and unsttructured. It felt like it was 2 labs in 1. The lab assistant couldn"t help us with any of our questions. In the end not even Lalya could help us so we had to go home since we couldnt continue.» (1 (very low))
- Way to much different tasks that had to be done. Half of them would be adaquite. Also it would be nice if we didn"t need to wait half the lab time for an answer on an explanation of a part of the exercise. Which was needed to move on to the next.» (2 (low))
- There were to much to do, we didn"t have time to reflect on what we were doing!» (2 (low))
- Good base idea, but WAY to many mini-tasks we had to show Lalya. Takes to much time. Much better to just show the 2-3 of the most advanced circuits and do the other tasks internally in the group.» (3 (average))
- Good: Since Arduino is a high-level platform it"s quite easy to build even rather complex applications in little time. Bad: Exercises were too many for the time we had at our disposal for the lab, there wasn"t even time to try to understand all the different stuff or to explain it to students with different backgrounds. » (4 (good))
- Good» (4 (good))
- Now it got interesting, but very stressful to make everything work. Also quite bad that not all components were available.» (4 (good))
- simple enough with clear instructions It was even easier than LAB1 and that is what surprised me» (5 (very good))
- good chose of microcontroler, and verý good instructions for the asignments. I think its a good way of working, copying the code and then changing it to your own needs, when needed.» (5 (very good))

- There were to much to do, we didn"t have time to reflect on what we were doing!» (1 (very low))
- See #3» (3 (average))
- having resource is good, but it is better to have more lectures about the theory behind them. And learn more about PD.» (3 (average))
- Same as Lab 2, but worse in the sense that here there was even less time to spend on a single exercise. This one felt really like we were in a hurry from start to finish.» (4 (good))
- This was a lot better lab then the one before. More structured and easier to follow the lab pm.» (4 (good))

- There were to much to do, we didn"t have time to reflect on what we were doing!» (1 (very low))
- Didn"t really like the textiles, sewing in these materials wasn"t that great. Also the keypad that we had to do could easily be lowered to a 2x2 keypad to ease the sewing.» (2 (low))
- Maybe better textile material could help.» (3 (average))
- Pretty good, would have been good with more introduction of how to connect inductive threads to normal electronics etc.» (3 (average))
- It was good in such a way that it let everyone know what was out there to work with, but as it was so hard to get any thing to work i dont think anyone wants to use textiles in this way. (with an exceprion for the strech sensor wich worked quite well) » (3 (average))
- Great to see new concepts of materials and how they work.» (4 (good))
- it was so much fun» (5 (very good))
- I liked Lab 4 quite a lot, subject is relatively new and thus interesting. To improve i just recommend to get more kinds of different e-textiles to experiment on.» (5 (very good))

- All instructions not availible in the beginning, no info on what was possible to order, unneccessarily long waiting time for components.» (3 (average))
- There were much to do, but we managed quite well.» (3 (average))
- Generally good, but allocated time is too little, especially because at least for my group the components we ordered took several days to arrive.» (4 (good))
- More time, to get components.» (4 (good))
- Nice to make a hole project in only 3 days.» (4 (good))
- good starting point for group projects to be prepared for the bigger UbiComp project» (5 (very good))
- Perfect! Letting everone utelize the groupmembers capabilitys to create something fun in three intenzive days. Bad things: problem with finding something to do, maybe more sugestions would help. » (5 (very good))

- Not very interesting to me, seemed pretty useless in a more general sense.» (1 (very low))
- was not meaningful and scientific» (2 (low))
- I didn"t really see any point to it. I was hoping to get a technical-ish lecture about musical interfaces, instead he mostly described the work of his collective (which i deem of very disputable interest), showed us a bunch of useless projects without even describing them, and basically did little more than self-promotion.» (2 (low))
- It gets low instead of vry low only because to highlight how bad i think dorkbot meetings were. Isnt there any good musicians out there that can really show some music instead of all this bullshit?» (2 (low))
- Out of topic for me!» (3 (average))
- Nice to hear what the field looks like from someone hwo works with it. How to make music instrument is also intresting and is somewath missing in the cource in the sense that the participants never constructs anything using midi or simmular.» (4 (good))

- Bad. Bad. Bad. The first guy hacked commercial electronic instruments without any kind of knowledge about it, or either was just very very bad at explaining it. The second guy was kinda freaked out, and didn"t even seem to know why he was there. In general the event was too artsy for my tastes. In all honesty I believe that we were pratically coerced (or else extra homework!!) to attend the dorkbot events because one of the teachers is involved with the collective organizing them and thus we were basically used to make the events seem more successful than they actually were. As a matter of fact i think we students were actually the ONLY (and if not, for sure the most) people in there.» (1 (very low))
- Why make this mandatory? It"s fun to have extracurricular events for those interested, but I"m not sure if that many would"ve gone if they"d known what it was about. It"s one thing to be creative, it"s another entirely to do useful and entertaining stuff. I do not learn by listening to loud noise. Also, several students had a hard time finding the place since they were new in town.» (1 (very low))
- Worst thing ive ever attended. Those guys that we were listening to didnt get my attention at all. The first guy starts off, with a bad english, presentating his homepage which is a white background with light grey text. Arent we going on a design program? After showing some other crappy homepages from the mid 90"s he started to "show off" his things. Apperently it was done with circuit bending, what circuit bending acculy is we didnt have a clue about untill the end of his presentation. So what about his "things"? I dont understand how you even can call it music... The other presentations during the evening followed the same pattern.» (1 (very low))
- I don"t understand why this was mandatory? It should be recommended for those who are interested. When people claim that they play music when they make sounds by "hacking" a device, they should at least have some kind of a musical ability to play it! This was awful!» (1 (very low))
- For me it was just strange noise everything. Can"t say I understand the meaning of turning something that sounds good into something that sounds really bad.» (2 (low))
- Presentation was poor. Especially the first one. The music demonstration is not very convincing.» (2 (low))
- The cultural aspect is wery nice to inegrate with the cource but the people in dorkbot are not wat i call musicans, so, good intention but bafd performance...» (2 (low))
- Low quality projects and a shame that it was mandatory» (2 (low))
- Cool to learn how artist making circuit bending, but lack of meaning.(but meet the goal of physical computing, isn"t it?)» (3 (average))
- Should NOT be mandatory!» (Not been there)

- This should NOT be mandatory!!!» (1 (very low))
- Same as the first Dorkbot. Just as bad. Again, people had trouble finding it. And seriously, putting mandatory events on a Saturday night?» (1 (very low))
- Like the last dorkbot there were some projects presentated, this time the presentations was a bit better made but still not intressting to me. The music acts was still a big question mark in my ears. What was those bicycles all about? To make those meeting intressting to a bigger group of ppl like our class i think you need to get some more entertaining presentations. Something that acculy can play music, why make your own mixer boards that sounds crap instead of using those that could be bought in the local music store and plays nice music if combined with a great user?» (1 (very low))
- I don"t understand why this was mandatory? It should be recommended for those who are interested.» (1 (very low))
- Low quality projects and a shame that it was mandatory. A bit more interesting beacause of the festival.» (2 (low))
- A little better than dorkbot #2, the first presentation here was actually quite interesting (read: technical). But still, i don"t like things when they"re forced upon me.» (3 (average))
- better but the bicycle thing was kind of pointless... » (3 (average))
- Presentation was good, but lacked a significant musical example.» (4 (good))

- Messy, schedule and deadlines were constantly changing, home assignments sometimes weren"t notified.» (Very badly)
- Way to many handouts came way to late, last-minute changes in the schedule, home assignments from one day to another etc.» (Very badly)
- The HA was too late to come up on the homepage. That we had to turn in HA on paper isnt a great solution either. We are going on the IT univeristy of gothenburg right?» (Very badly)
- Make the material be online faster and ever before the lectures. After just one or two days one forget about what the lecture was about if thers no material to read.» (Rather well)

- Great!»
- great, it was hard to find a proper glue / adhesive tape though»

- Not enough components!»
- Really bad organisation, very hard to find components. Many bog standard things ran out (wires, specially in black and red (both multi-threaded and single-threaded), resistors, leds, piezos, soldering irons, etc, etc). Most of these things cost <1kr each - buy 100s of them!»
- Pretty good.»
- very well»
- well, the studio was a mess and a lot of time was spent searching for stuff that was there but was hard to find...»
- It was quite good. A bit hard to find components in the small boxes but overall quite okey.»
- At the beginning there were a lot of components, but in the end of the course it was hard to get some of the components. But overall good »
- I am amazed that we have so many equipments.»
- Great in the begginning but since this many people can"t work in the same space and still take care of their own it got quite messy fast. Maybe people have to sign a contract for using the studio or you could split the class into two smaller groups so the anonymous of persons being ignorant disapears. Also a better quick education (short one) to be credited to use the studio and the workshop. Was really awkward to have one the students demonstrating the workshop, since he was all unprepaired and couldn"t answer about specific questions or procedures in this lab.»

- The labs were the hard part of the course. To get a high grade during lab exercises you had to keep a really high pace. We never had any breaks during labs. This stressfactor made it harder to take in all the information and to really learn it. Think it would be more successfull to remove some elements to increase the learning curve. Appart from the labs it was chill.» (Adequate)

Genomsnitt: 3.06

- Covered topics are per se good and interesting, but imo there"s room for a lot of improvements in both practical organization and perspective of the teaching.» (Fair)
- The labs could have been better, but dorkbot was a disaster!!» (Fair)
- In contrast to all I complained about I will also say that I liked the idea, the intentions, of the course and in general it was interesting and fun.» (Good)
- I wich this was the first course i took when i started my chalomers studies. It teachjes everything in a very easy and hands-on way. Much because the ardruino is so easy to work with. » (Excellent)

24. What should definitely be preserved to next year?

- I think the home assignments were unnecessary! We spent too much time on this course and when we needed some free time to spend on the other course...this was really annoying! So if possible, reduce the home assignments or specify a period in class time to do them!»
- The mini-project was absolutly the most fun part to do»
- Arduinos, they"re definetely a good tool to play around with.»
- Lectures about the technology and projects. Mini-project.»
- The mini project is a good idea. The labs are useful to learn. The optional lectures are a plus. The musical aspect could be pushed further, if it was more open to more traditional music making´,.»
- The Arduino»
- The last exercise.»
- the ardruino!!!»
- The labs, but some changes might make them even better. Its a practical course and build on to that.»
- labs are good, but to much to do»
- The straight forward trying-and-learning philosophy»

25. What should definitely be changed to next year?

- Better planing. The differnent tasks we are suppose to do need to come up much earlier. We have another course parallel to this, and don"t have all the time in the world to do the tasks.»
- lecture should be more detail not just show the webpage,and interpresent some principles.»
- Lalya. No kidding.»
- The course should be made more flexible. Students should be allowed to pursue ideas that interest them. Groups should be formed when students feel they can pursue their ideas better within a group - not because it"s a university requirement.»
- The labs could have more components, and a more structured approach. Those who have little knowledge in electronics will not have anything more at the end of this course. Maybe a more structured approach, or labs to support the first chapters of the book will be useful.»
- You REALLY need a soldering course (this year we had a useless "component layout" course), with slides with how a solder joint should look like, temperatures, solder application, etc, etc. Maybe you should consider replacing Lalya with someone with more knowledge about the course content, electronics and computers in general and also someone more flexible.»
- No mandatory events outside of the schedule.»
- Short, writen description about how we can search for mistakes in the circuits. What to do when circuit doesn"t work. How to debug it.»
- The blog was just a pain in the ass. I dont think anyone learned anything out of that. Maybe have seminars where you ask questions about one or two articles instead of how its atm.»
- no mandatory dorkbot»
- The pace of course.»
- The blog-reading, the context of the lectures and the level of mandatory content of the course. Set a level of mandatorety of 70% for lectures or so... Maybe Lalya shouldn"t be the person i charge of this course, but then she made improvements so maybe that"s no problem next year.»

26. Additional comments

- Very good content of the course, VERY bad course in general!»
- I didn"t have experience with building circuits before I started physical computing course. I was missing "tools" to find errors in the circuit by myself.»
- Course could be improved by moving more focus to the labs, and less on useless musical interfaces and such»
