  1. I think your best bet would be to look at www.item24.de, they specialize in extruded aluminium. Well documented, you can find loads of information on their site about weight distribution and stuff. I think some guys on this forum already used their services Rails for building cart? in the DIY subsection of this forum). Another option could be using T-slot or V-slot profiles (with lots of possible joinery and other options from openbuilds), commonly used in diy 3D printing and CNC machinery. Probably less documented than item24 above, so no real idea how solid it will be for heavy duty jobs. I've built some enclosures with 20x20 profiles from Ratrig and they feel very strong already, so I guess if you'd use larger profiles, you'd be ok. As for wheels, look into any decent bike shop, you'll have enough choice for small, strong and light wheels (in the picture you posted, it looks like a 20"-ish bike wheel). Look into BMX rims if you want strength, they are designed to take some abuse.
  2. I bought a UwMic 9 system (a set of 2 Tx and a dual RX, with frequencies compatible in Belgium). And a XLR plugin. To see if I could recommend it as a cheap alternative to students. Long story cut short, I don't recommend it. First of all the plugin Tx came dead on arrival. Backlight turned on, but that's it. What I also immediately noticed was that the XLR plus was quite short, and I confirmed it with the fact that it doesn't hold well when plugged in (a little lateral motion and it pops off. Even slightly jiggling is enough to make it fall off). The store I bought it from was quick to exchange it with a working model. But the XLR problem remains. The XLR connector looks like the front part of a Switchcraft XLR, so I managed to modify the Tx with a Switchcraft part (with a little elbow grease and a Dremel). By doing the modification, I understood that the problem is a combination of the XLR connector being slightly too short and the locking pin being too small (and rounded to booth). After modification, it holds now. Has phantom power, nice. So quality control seems off. The beltpacks come with integrated antennas, quite thick and quite stiff, not removable. Care should be taken to store them properly. They are very sturdy (metal casing), but quite heavy also (way heavier than a G3). But then the stupid part, the battery compartment is in flimsy plastic. They use more power than Sennheisers, batteries don't last as long. The Rx comes with a belt clip and a camera adaptor. Also a minijack to XLR cable (with caps to block phantom) comes with it also. Only mono though. Which is a shame, because the first models mixed both channels to a mono output, but they were quick to put a setting in the newer firmwares (as far as I know, not user updateable) where you can chose to output each channel separately. But then you need to make your own cable. Separate phone output, but doesn't go very loud. Each Tx comes with a lapel mic also. Problem also, the lapel clip seems to be glued to the microphone, you can't remove the mic without breaking the plastic clip. The sound of the Mic is meh (quite nasal, and not a lot of air). The Tx are modelled after Sony's, so the mic cabling follows Sony also (if you have Senns, you need to rewire them). Main problem I find is that there is no sensitivity setting in the Tx, only the output of the Rx can be changed. The mics that came with the Saramonic seem to be quite sensitive, as I couldn't get adequate level with any other mic (I used Senns, DPA's, Sankens, even hi sens models, they didn't reach the level of the included mics). So forget using them as hops, unless you can pad down to mic level. Same with the plugin Tx, no input level setting. Setup is quite easy, the Rx has an autoscan feature for each channel. Once a free frequency is found, you can just hold the Tx close to it, and they'll sync up properly. Rangewise it's adequate. Haven't run into problems inside, even with thick concrete walls. Outside, I managed to get about 120-130 meters before getting drops (30mW). There seems to be a squelch, but you can't modify it. Soundwise, meh. If you use them with the included lav mics, the levels are in the sweet spot for talking. But no input level setting means as soon as it gets louder you risk clipping. And if the levels are low, there's some audible expanding going on. As I stated, the lack of input gain setting is a big no no for this system, it shows it was made to a budget. Key test, scratchy as hell I firmly believe if they would add an input setting in the Tx, they would have a capable low budget system, but as it is now, stay clear. I contacted Saramonic with all those details (both US and China), never got any reply. So I don't know, they don't seem to care. So basically, you get what you pay for. Stay away if you care about sound. If you want a good cheap system, G3's remain tried and tested.
