I was hungry, so I bought these today (random internet image below, not actual victim. I ate mine before I got it to pose for me)

I just finished "Calculus For the Practical Man" after a year so to reward myself with more toil, I bought Feynman Lectures on Physics volume 1, some 0.5mm Rotring leads and The Songs of Distant Earth (CD version) by Mike Oldfield.

The most fun you can have for £30 these days.

this thread should really come with a warning... Make sure you pay the rent and bills BEFORE you buy shiny new gadgets... I forgot them in the excitement. In fact the forum should have a warning of such and how addictive it is.

Deathwish, I just got the same LA. I haven't actually used it yet, but I installed the Saleae Logic software, ver 1.1.15 and the software reports it as a Saleae LA and it paired up immediately. Win 7 Ultimate 32 bit also installed the driver without an issue.

I loaded mine up with the new 1.1.34 software and it loaded up and recognised it the same, win 7 ultimate 32 bit as well.

I will try the same, thanks.

Edit: I tested it with the clone and my Arduino and it all plays well together. Now for the learning.

Bought THIS a few days ago. It's on its way here now. Surprised me when my offer of $100 was accepted! Can't wait to play with some high voltage (low energy) circuits...

BTW - the same seller has another one - slightly less pristine looking - listed for $149...

Four 50W LEDs. One each R, G, B & Cool White.
I'm starting on my next 'microscope light' project. This one a bit more powerful than the last. http://everist.org/NobLog/20150510_Olympus_bhm.htm That was 10W, this one will be 200 to 300W max, adjustable for normally lower output.

The aim is to get all the light from these mixed and steered down to a small diffuser aperture about 3mm diameter. Or less, maybe. I think it will be something unwise to look at when lit.
Lens coupling from the small aperture to the microscope.
Maybe I'll be adding 50W UV and IR LEDs too. Still looking for R & G 50W LEDs that are not pathetic in output compared to the Blue/White ones. Seems sad that R & G LEDs lag so much in efficiency.
Anyway, the idea is to have individual current drivers, for an adjustable spectral distribution.

Pics are the bare LEDs, then mounted on heatsinks with fans.

Oh, and I bought 200 ordinary 5mm Red-Green bicolor LEDs, for that 'magic LED ball' experiment. In the post.
See https://www.eevblog.com/forum/projects/magic-led-ball/

Edit: Correction. I take back that bit about the green having pathetic efficiency. Also that these would be eye hazards once concentrated to a near point. Powered up, the green is completely impossible to look at. I made the mistake of looking at it for a very brief instant just before leaving to drive to pick up a pizza (at night.) Mistake.

These were from ebay http://www.ebay.com.au/itm/111299756188
50W Color: Cool White USD$2.99 AU$3.85
50W Color: Red $3.13 4.03
50W Color: Green $2.89 3.72
50W Color: Blue $2.99 3.85

Operating: DC32-36V 1750mA

Red 620-625nm 500-550lm <---
Green 520-525nm 500-550lm <--- perhaps these '500 lm' are plain wrong?
Blue 450-460nm 2500-3000lm
Amber 585-590nm 2500-3000lm
Cool White 6000K-6500K 6000-7000lm
Warm White 3000K-3500K 6000-7000lm

It's interesting how much more sensitive eyes are to green than blue. On the same drive power, the green looks *much* brighter than the blue (going by reflections, not directly looking at it.) Yet the simple 'how close can I hold my fingertip' test says the blue is outputting easily twice the radiant energy. 'Ouchy' distance is about 2 cm for the blue, 1cm for the green.

I still find the idea of an LED you can't hold your finger next to amazing.
It's a relief to find these heatsink-fan units are adequate for 50W LEDs. But only with fans going at full 12V. Dropped to 5V, they warm up fast.

Hmm... I'm starting to wonder if all of these actually have blue LEDs under the phosphor. When I put the Red, Green and White LEDs (unpowered) in the light from the Blue one, their cover materials all fluoresce brilliantly. The Red and Green ones are not just tinted covers over Red and Green LED chips.
Pics below don't capture the effect

I recently bought some 320x340 SPI 2.2" LCDs for something below 5€ which I wanted to use as default display for future projects.
Now I found some 2.4" displays with the same controller (ILI9341) and additional touchscreen (also kinda SPI) for slightly below 6€.
Couldn't resist.

And yeah well, some ultracheap FT232L with additional pinout and 3.3/5V jumper. Let's see if they are fake

New ( to me) computer, Fujitsu Empriso. Was $150, and currently sitting in the corner after doing an overnight run of diagnostics, and busy now doing a new OS install of Linux Mint. About an hour to go till it finished install and reboots.

Just scored a Panasonic Lumix DMC-SZ8 Camera from Officeworks for $40, they were clearing these out for $58 and the only one left locally was as new but missing the 240 to 5 volt USB charger so I took one that I had for my phone to the store and asked to test it first, worked a treat, happy as larry I was.

Basic auto focus point and click camera with 3 inch screen, looked bigger in the pictures, next time I will take more notice of the dimensions in the specs. Also it uses a proprietary 8 pin micro type USB connector for charging and data transfer, one manual said no charging through the port and other documentation indicated that USB charging through the supplied cable was fine, didn't risk it so checked before hand.

I despise proprietary connectors and hate conflicting documentation even more so.

A new drain pump for our Bosch Nexxt 300 series washer. Damn washer broke down just before company came to visit. A new pump was $75 shipped, 4 days to the door and was fairly simple to change out, outside of the traditional bloodletting along my arm from squeezing into a tight place to remove hoses. After almost all the towels in the house were used up going to the beach, it took 2 full days to catch up on all the laundry. I should have listened to SWMBO and used the local laundromat and get everything done at once.

As a side note, the Bosch Nexxt 300 series combo is the worst combo we have ever owned. The washer has been finicky since day one and the dryer blows the temperature limiter once a year. Luckily the part is cheap and easy to change after getting the 1/2 ton of screws out of the back. Any setting other than regular dry results in the clothes smelling like they were burnt. I wouldn't be surprised if we could smelt metal on the extra dry setting. All this for only $1600 USD for the set. When these finally die, we will get anything but Bosch.

I could have bought a used Icom 746Pro for the same price or cheaper than the IC-718 + IT-100 but I have not had good experiences with others used radios.

I plan to mostly work CW, Contest and get some Awards. I plan to add a few more antennas to it. One thing that attracted to me to this radio is the portability, so I will likely be operating portable a few times, probably from a beach (Atlantic Ocean) location.

I had been on the lookout for a scopemeter for a couple of weeks now, but couldn't really find much of interest. Ended up bugging TopLoser for one, and he gave me a great deal - I felt so bad when I had to decline! Got an email notification from a local "ebay", someone selling a Philips/Fluke PM97 just down the road (3 minutes walk). Went down immediately and here it is:

Guess what I paid?

$45!

Actually I build a lot of stuff! But After selling my old rigs, I wanted to get back on the air asap. So this is what I did. I plan to build some SDR's and QRP rigs, as well as some antennas. One of the things I am building right now is a Go Box with solar controller, AGM battery, a panel, power buses, etc.

Time is a premium for me though, so I have to be careful about what I decide to take on.

I am also building a workbench for a lot of this stuff to live on, so wood, miter saw, ground bus bars, basic stuff, but takes time.

I am not crazy about those scope meters, but for $45 I don't think anyone could pass that up, rather nice! I didn't even think you could get one of those for 10x that.

Well, went to the dentist today for a check up, and asked him if he had any old dental picks he was going to throw away. So got an assortment of 5 dental picks, a set of tweezers and 2 special tools, plus a bit of mercury amalgam that was hiding inside, which had survived a good few autoclave cycles.

Bonus points if anyone can identify the 2 tools on the right, as I doubt many have seen them before. I don't know if I will use them as is, but they might come in useful.

Was chatting after the polish ( interesting that the burnishing tool is a plain disk of SRBP material used to abrade your tooth, used once and then thrown away) and when he upgrades the Xray he will call me........ now I have to find some scintillator film in the interim, to make up an imager using an old CCD camera or just a camera obscura with the sheet and a sacrificial cheapie camera I have around.
