  1. An update on the bus/shed heater. It is now powered by a 30A power supply, and the exhaust is extracted with a 150mm fan and ducting. I got a whole lot of ducting leftovers for $60 off marketplace. The fan was a freebee from when I worked at a tech company in chch, they cleared the storage out and let us take what we wanted, I grabbed loads of shit. I still have boxes of ally brackets and bus bars in my container... The fan is pulling right on that exhaust so I checked the temps while running it, it hits 43 degrees on high, 30 on low. That ducting isn't sealed so it is sucking air as well. The fan is a Pabst that is rated for 70+ deg so should be sweet. Still need to mount the supply and an RCD in a box for safetys and cut a hole in the shed to waft the fumes out.
  2. I made an executive decision and bought a 24v 30a power supply. One of the batteries was completely toast, the other not far off it. I used another to get it going but I would still need some more batteries plus something to charge them. I have also discovered it doesn't like anything connected to the exhaust so might extractor fan it.
  3. https://waveinverter.co.nz/shop/accessories/powersupply/powersupply-24v-20a/ Or maybe 2x PC power supplies feeding each of the batteries? Basically free from the dump shop.
  4. So that supply is 8 amps roughly? Could be worth a try.
  5. I am a man who mostly finishes projects. I don't have the room for too much unfinished shit. Maybe. I could actually sit this outside the shed under a wee roof and make holes for the ducting. This means I don't need to worry about the exhaust too much either, then set up a couple of panels for charging the batteries.... It could work.
  6. So how about I get an 8 or 10a 24v power supply and hook it up to the batteries. That will run the fan and supply a bit of charging current....?
  7. I may as well leave it running in the room and forgot the heater completely.
  8. Yea the batteries make sense to deal with startup, then it's a case of supplying running current. In reality I would probably disconnect the power when unused as long as it had enough jibber to charge it up a bit while running the fan.
  9. What about a big PC power supply? I don't know how common 24v would be on those.
  10. My little 5.5kW eberspacher drew 10 or 15 amps initially, this is way bigger. I found a user manual, fan is 4 amps, there is a glow resistor that I think this is in series with the glow plug, this should measure between 15 and 17 amps. So 20 amps on startup probably.
  11. This one is appealing to my sense of hackery and danger.
  12. Maybe, although it may be good to supply some amps to run the fan after the initial heating draw...?
  13. No unfortunately, there is a big ass heating coil that draws lots of current for a bit, then it's just a fan. Hence the batteries to buffer that.
  14. Bitches. I have purchased a large Mikuni diesel bus heater that I will use as a shed heater, for reasons. It is 24v, and I happen to have two spare batteries that are mostly fucked but may do for this situation. What would be the best/cheapest way to keep them charged for starting and also when running etc? I guess the most budget would be a couple of cheapy battery chargers, but would they cause issues if left hooked up long term? What are your thoughts O wise ones.
  15. Yea so I have set up a budget recording studio in my shed, it works pretty well. I have been playing with getting a good sound when recording acoustic guitar. My main go to acoustic is a K. Yairi that I bought brand new in 1992. It has amazing looks, sound and playability, but access to the battery for the pickup has always been a drag, you have to loosen off the strings and get a fat hand in through the soundhole. Also if it is left plugged in it will drain the battery. So I ordered a Gotoh panel mount battery box and got to work. This was pretty scary as this guitar is pretty much my most prized possession. All seems good. I added a switch to isolate the battery as well, so if I leave it overnight plugged in and set up it will still work the next day...
  16. Some crane action for yiz; That's a massive Mikuni bus heater that I bought to heat the lined and insulated bit of the shed. It cost $100, still had half a tank of diesel in it, they are big tanks so I am probably at a net profit.
  17. We will sort it once the 1.3 throws a rod doing a 12 second pass at 13800 revs.
  18. Andrew is the man I got all my kit from. It was from his first machine he built when he was 16 or so, and he had ripped it all from a machining center or something. He is a good man.
  19. Viking Machinery in chch is where I got my breakout board and prox's. He was a good dude, very helpful.
  20. Probably because I had success with it. Once I had googled the IO for the servo drivers and bought a breakout board it was pretty simple to set up.
  21. There is also the challenge of getting an NA 1.3 to run 13's.......?
  22. Shit man I'm happy to put in a fiddy for another junker engine to see things keep moving, I am sure there are many more here would do the same. Time for an onlyfans.
  23. I'm excited for exhaust stuff. I think you will see big gains. Anecdotally, my x1/9 sounded amazing when I put 40s on it but wasn't really all that much gruntier. Then I made some headers based roughly off the Guy Croft opinion spec, although smaller pipe sizes cos it wasn't a race engine and I wanted it to fit the bodywork, and I immediately gained 800-900 revs and a big increase in livelyness all around. So yea, make it happen ....
