Re: 401 Size Can?
Group,
Who cares about stares, just bring a Tuna kit with you to the store. Measurement solved

Tuna Power
1) The LIFEPO4 has a BMS battery management system that will cut off the charge once it has determined it is FULL or ~14.6 volts. 2) The charge voltage of the UC3906N as hardware programmed is actually only sufficient to change the LIFEPO4 battery to approximately 66% at 13.8 volts. So overcharging isn't actually likely. The charging input voltage is asking for an 18-20 volt wall cube which is the same as a solar panel with peak power at 18 volts and an open circuit voltage of ~20 volts. I have a 20-watt solar panel that outputs a 1-amp peak in the ideal sun with afternoon temps in the "cool" range. This seems ideal. Any more and the 1N4004 Rectifier diode would need to be upgraded. A 1.5 - 2-amp suggestion? At one amp that is a good idea anyway just for the margin of cooling safety. So for a long weekend of camping and Tuna operating, the solar panel could extend the operating time of the 6 AH battery and a conventional LIFEPO4 changer could be used on the disconnected battery after the fun is packed up for the weekend. It seems that the T.P.S. hasn't been passed over in technology quite yet! Stay tuned for a video on it, of course! Davey - KU9L |

Re: 401 Size Can?
Love the monkeys! We had a family friend who had a Capuchin monkey named Tessa. She was ornery! I met a Capuchin monk (OK, friar), when I was in Detroit a few years ago, too. He was a really nice guy, but I don't think he was a Ham. I have no idea if Tessa or Br. David like Cappuccino. I don't.? I do like a good cup of regular coffee with nothing in it, though. Isn't it great how thoughts can chain together??? I think your can is very close to 401 (4" 1/6" OD), maybe within wiggly tape measure end slop. At least we hope so. The upside is the near-certain future of chicken salad sandwiches. Maybe a win/win! -HRS H. Russell Smith, N0QLT???

Our WM is next door to our snowbird campground and walking distance, but before I take the two hour drive to Costco I thought I would seek an extra breadcrumb locally. My next search will be Public 3 miles away. Cheers es 72, Davey - KU9L |

Thanks, Aldi is the same distance as Publix for me. A sure way to get stares is to go into the store with a tape measure, LOL. -Davey - KU9L

Tuna RF Monitor
Even though this kit still has no formal build instructions I decided to go ahead with assembly using the Schematic & parts list. The kit included all parts needed and the tuna can.
The kit has 3 L.E.D.s, but only the orange L.E.D. lit, so upon troubleshooting I suspect the silkscreen for the Red & the Blue L.E.D. may be marked backwards. Also, the board layout is slightly different than the current schematic, for layout convenience I suppose. After solving that little mystery all three L.E.D.s lit as expected.? Mostly this kit is just for fun, but I enjoyed the power measurement & dummy load section. I was able to measure the voltage at the peak & hold circuit so I could calculate the RMS voltage? (including the 0.4 VDC diode drop) & use ohm's law to determine power output of my transmitters. However, the 6 watts of dummy load will never get warm if one stays within the one watt maximum recommended power through the monitor circuit. I recorded this short video just so everyone can see how the L.E.D.s light up.? It was a fun kit to assemble & almost as much fun to troubleshoot to make sure I did not screw up the component installation. BTW, I spent 20 years fabricating test fixtures & writing software to test printed wiring boards for correct assembly that were to be installed in aerospace black boxes for aircraft & spacecraft. I do not miss SMD components, I love the old through-hole components just because that represents the hay day of electronics for me. SMD parts. Once the tiny SMD parts came, microscopes became my tool of choices, but my tired eyes didn't like it, lol. Cheers es 72, Davey - KU9L |
Re: Rockmite ][ Assembly Instructions/checklist
To answer your question directly, no there isn't a step by step guide for the RockMite][.
?
All the documentation you need is on the QRPme website. One thing I would say is read the material thoroughly and really get your head around it. The RockMite is quite a simple project in reality, but with Rex's version, there's quite a few 'builder's options' which may leave you confused.? Good luck, 73 Colin |
Re: Rockmite ][ Assembly Instructions/checklist
¿ªÔÆÌåÓýNo, you didn't overstep. I was making a
point that EVERY document for QRPme kits is sitting somewhere on
the QRPme.com website if it is in either mine or Chuck's computer.
Occasionally, someone looks for a very old document that was on my
old gigantic 1 page site that didn't get ported over, but anything
from the last 15 years or so should be there somewhere.
The doc you are searching for I believe
was generated by B. Scott Anderson, NE1RD. If you google NE1RD and
the document, you will probably find it on his site.

Re: Rockmite ][ Assembly Instructions/checklist
All, Seems that I have accidently over stepped. Rex? I was searching to see if there was a manual for the Rockmite ][ that was similar to the 49 page manual for the original Rockmite that had a step by step checkoff list with images of each step similar to the old heathkit radios.? I checked QRPme.com for something similar but could not find it. So I sent a query to the group. If this document is on QRPme.com and I missed it could you please point me in the correct direction? If not I will figure it out. Dan KD4VBV? On Tue, Feb 28, 2023, 7:36 PM Rex Harper <w1rex@...> wrote:

¿ªÔÆÌåÓýGangue, Remember.... this [email protected] is an email forum/group. It is NOT my website! If you are looking for kits, instructions, schematics etc for a particular QRPme kit you really need to look on the website: Almost all the historical documents are there... that's Rex?
