This all sounds like the genesis of a good book - Canepa were are you?
I still have a Cambridge IAX-95. It would do dual deploy and My first try at that was with the Cambridge for my level 2. Now I fly the Quantum from Chris at Eggtimer and just can’t see any reason to use the old altimeter because It is just to big and way behind in technology.
Yeah but it's so cool to use a vintage altimeter and if it augers in, in a beater rocket, you can say you gave it a good death. I think I have a Cambridge around or one related to it but if not, the early deployment altimeters were of monstrous size. One of the problems is getting the early programming software to work on WinBlows "so and so". Not so hard if one keeps a "vintage" computer around!!
I've got an altimeter that has 4 channels for deployment from the early days, I have to go downstairs to look up the name. Has like 200 pages of instructions I printed off from a computer and I never had a rocket or a chance to fly it. Did connect it up to an old computer and it checked out o.k. Would have to use a serial port to get it to connect. Don't know if my old WinBlows computer will boot up for it now. Compatibility is an issue with old electronics. I had to connect a battery to the programming cable directly (came with it when I bought it used but it was extra cost otherwise) to get the altimeter to communicate to the computer! That is freaking outrageous in this day and age. It worked though back then.
Oh and all the "stuff" cost extra back in the day. battery cables, programming cables and such with quite a markup that one couldn't avoid if they didn't have a deployment device that had simple jumpers to do the settings with. If one could set the jumpers, if "ya" wants to get the data off the thing ya's got'sa pay extra for the freaking cables for your freaking computer!!
I started getting back into rocketry around the early 90's for a frame of reference but there were old deployment devices floating around for a long time thereafter some of which I picked up.
I need to go downstairs and see what I got. Got off track when my wife died and I retired to take care of the home and my mentally handicapped son. He's doing well and I could get back into launching if I could get out in my workshops, garage and basement, clean up and get back into building.
Nowadays, it's usually easier to get data off a "device" as a cable is provided or Bluetooth is used to make it easier or harder as it may be.
Had most of my altimeter programming software working under Linux back in the day and had a version of Rocksim running fine under VMware and actually WINE in Linux. Now if only I could find those "danged" hard drives and remember the stupid passwords!!! (I pulled them from various laptops. Still think I got them around.)
Got sidetracked by work, my life, my son and my wife's illness.
Glad to be retried now.
Does anyone have pictures of an Olsen or maybe Olson Altimeter? I think I saw one once and it had an lcd screen on it.
Great! Now I gotta go digging. I know I have one, but never flew it. Crazy small, originally designed for (I might be assuming) S8E flyers and those of other ilk that follow the things with wings program. I bought it for a rocket glider that was never born.My first alt and it still works! Winged Shadow ‘How High’ circa 2006 or so. Quest had a licensed version as well.

The various flavors of "How High" devices were quite interesting and worked very well. They have a really low sample rate (1 Hz) but if your flight is reasonably vertical, that's good enough to get an apogee within about a meter. I think that was the first dedicated rocket altimeter (well, at least suggested for rocketry use, but out of the model airplane world) that I flew.Great! Now I gotta go digging.

Heck, Y'all youngsters or what?
I actually had one of these when I was 7, (50 years ago) my parents got me one for Christmas - The Estes Cineroc. I took it apart to try & see how it worked & never got it back together again. I still do stupid stuff like that.
Is the MAD unit one of Dr. Galejs's? If so I flew a bunch of them awhile back and they worked just fine. I dorked one of the units in building and he fixed it for me! I think I built 3 of them. Great guy.I have an Olsen timer. Also still work I believe. Also a magnetic apogee detector. Not transolve. Never had the guts to try it.
Yes, it had a 2-line LCD display. I think I have one in a rocket stored away. If I can find it, I'll post a picture. I have several of the old units. I need to get them all out and take a photo. 20 years of electronics history.Does anyone have pictures of an Olsen or maybe Olson Altimeter? I think I saw one once and it had an lcd screen on it.
I think I have one of those too but don't remember who I bought it from! I have a Mission Controller deployment altimeter which I think was one of the last sold. Had four deployment channels on it and the programming software was a nightmare. The software loaded on a WinBlows computer just fine but there were a "buttload" of parameters one had to set! I had to connect a 9V transistor battery up to the programming harness so I could program it through a computer! That was ancient times! What a PITA! Never flew it as I never had a complicated rocket that needed the 4 channels on it. Was an impulse buy as most deployment altimeters only had two channels for deployment at the time and I had some money to spend. Two channels was all I needed. I bet if I connected it up to an old computer and figured it out, it would work. Actually, I probably could fly it as I kept it in the proverbial "cool and dry" place!.

For awhile I flew cardboard rockets. If there was a major deployment failure, aka lawn dart, they splattered in the cornfield. I was lucky if I could dig out the nosecone. Had a 4 inch Loc tubed project that went in. I learned early on to bring a spade and a shovel to a launch site. If not my project I gratefully loaned my digging hardware to an unfortunate flier. A similar rocket is in the picture above with my lovely late wife. That rocket still survives as I "mastered" sort of flying thin walled, cardboard rockets. Apogee deployment has to be "spot on" to avoid a zipper. It's a thin walled DD Loc tubed rocket that took me 8 years to get a nominal flight out of. The fincan is bullet proof and I could always replace the upper tubes for one reason or another (mainly zippers).If you want electronics to work, even after a 100g ballistic recovery, you have to pot it in epoxy. Humaseal will help to a point, but not like the right potting epoxy.
