Since I inherited an old HP 8753C Network Analyser from work, I figured updating a few things to relatively modern standards would be good. The factory CRT, being 28 years old, is definitely getting a little tired, not to mention being slow to warm up. I read over on the
These photos were sent over to me by a friend, an interesting piece of tech that’s used in the retail industry. This is a BluVision BLE Beacon, which as far as I can tell is used to provide some automated customer assistance. From their website it seems they can also
I posted a while back a teardown of the VM Superhub 2 router, as VM has “upgraded” to a rebranded Arris TG2492S/CE CM. Alas Virgin Media in their wisdom have decided that simple router features like being able to change the LAN subnet & DHCP server range are far too
Since this phone has been in my drawer for some time, I figured it was time for a teardown. (It’s never going to see any more use). The back cover on these phones is easily removed, as it’s just clipped on. Once the back cover is removed, the Li-Polymer cell
Here’s some teardown photos of an old De La Rue coin counter, used in businesses for rapid counting of change into large bags. An overview of the whole mechanical system of the counter. Coins are loaded into the drum at the rear of the machine, which sorts them into a
A lot of the electronics I use & projects I construct use batteries, mainly of the lithium variety. As charging this chemistry can be a little explosive if not done correctly, I decided a proper charger was required. This charger is capable of handling packs up to 6 cells for
Here’s another retired piece of tech that we used to route media from the NAS to the main TV. It was retired since it’s inability to support XBMC/Kodi & having some crashing issues. After attacking the case with the screwdriver (Torx in this case), the main board comes out.
Since the boat was still running it’s internal network on 10/100M speeds, an upgrade was decided on, the internal WiFi signal strength was also pretty poor further than a few feet from the NOC. The new router is a Cisco/Linksys AC1750 model, with gigabit networking, and full 802.11ac 2.4/5GHz Wireless.
To cap off the series of scripts for doing easy timelapse video on the Raspberry Pi, here’s a script to generate a H.264 video from the images. This should be run on a powerful PC rather than the Pi – generating video on the Pi itself is likely to be
This is basically an industrial, rugged MP3 player, in an extruded aluminium case. They are used in commercial settings for generating telephone hold music or continual playback of background music in shops. It’s quite a compact unit, in a nice aluminium case, designed for mounting into a comms setup. This
I recently dug out my other card printer to fit it with a 12v regulator, (it’s 24v at the moment), and figured I’d do a teardown post while I had the thing in bits. This is a less industrial unit than my Zebra P330i, but unlike the Zebra, it has
As per my site update post, I have migrated my radio log onto a new system, from CQRLOG. CQR log has served me well since I first started in Amateur Radio, however it’s a bit complex to use, requires a backend MySQL server for it’s database, and as it’s a
I have recently begun to create an archive of all my personal data, and since LTO2 tape drives offer significant capacity (200GB/400GB) per tape, longevity is very high (up to 30 years in archive), & relatively low cost, this is the technology I’ve chosen to use for my long term
Here is a home laser hair removal unit, a Rio LAHS4. Shown above is the system overview, with the laser wand & the user controls. Main base unit popped open reveals the main PCB, with the central processor, a PIC16F628A. Other side of the PCB is mainly populated with power
As the first USB hub I was using was certainly not stable – it would not enumerate between boots & to get it working again would require waiting around 12 hours before applying power, it has been replaced. This is a cheapie eBay USB hub, of the type shown below.
Here is an old chemical dosing system for industrial washing machines. These units are 4-pump models, with dual pumpheads. The motors are reversed to operate alternate pumps in the same head. From 2006, this is a fairly old unit, and made in the UK. Main controller PCB, with interface to
This will be the record of building a new Media PC, above you can see the finished system. It’s Mini-ITX based, with on-board HDMI output, specifically to run XBMC via Fedora for media purposes. This is the case that is being used, around the size of a Shuttle PC. It
This is the teardown of a Zebra P330i plastic card printer, used for creating ID cards, membership cards, employee cards, etc. I got this as a faulty unit, which I will detail later on. This printer supports printing on plastic cards from 1-30mils thick, using dye sublimation & thermal transfer

An early speed radar detector from the early 90’s. Pictures showing the front of the unit with the option buttons. Bottom of the unit showing label. Unlike the newer plastic detectors, the whole casing of this unit is cast aluminium. Model Uniden Stalker RD-6000W. PCB removed from the casing. Volume/power
Here is a PSP Slim that recently died. For those that are interested, here is the ID label, this is a PSP-2003. Here the front of the unit has been removed, showing the first internal components. Here is the unit with the LCD removed, here the mainboard is partially visible.
This is an old cordless landline phone, with dead handset batteries. Here’s the handset with the back removed. Shown is the radio TX/RX board, underneath is the keyboard PCB with the speaker & mic. All the FM radio tuning coils are visible & a LT450GW electromechanical filter. Radio PCB removed
